Authors:Jemima Owusuah Asante, Faustina Wireko-Manu, Christopher Larbie, Gertrude Nunana Kpodo, Ibok Oduro Abstract: Food Science and Technology International, Ahead of Print. Herbal teas are ingested for various purposes and by diverse populations across the globe. There is a growing recognition among individuals of the advantages associated with the use of this beverage, leading to a heightened demand for the manufacture of herbal tea derived from therapeutic plants. Spices on the other hand add flavour to food but could pose harm if it is high in phytates and oxalates. The objective of this study was to develop natural spices and herbal tea with health beneficial properties using Solanum nigrum and Solanum torvum berries. Herbal tea samples from S. nigrum were prepared by sorting berries, maceration, divided into two (fermenting at 18 °C and non-fermenting) and dried at 60 °C for 12 h in a hot oven. Spices from S. torvum and S. nigrum were prepared by removing the berries from the stalk, freeze-drying and smooth milling into fine powder. In addition, antinutrient, phytochemical and sensory evaluation studies were conducted on these spices and herbal teas. A nine-point hedonic scale was utilized for the purpose of conducting a consumer acceptability sensory evaluation test using 101 untrained panelists. Data was then analyzed by t-test, one-way analysis of variance (ANOVA) and the level of significance (p Citation: Food Science and Technology International PubDate: 2024-07-26T10:02:15Z DOI: 10.1177/10820132241266103

Authors:Khadije Abdolmaleki, Farahnaz Rezaei, Reza Mohammadi, Leila Zare, Saeed Shahmoradi Abstract: Food Science and Technology International, Ahead of Print. Edible films containing anthocyanin and betacyanin as indicators of freshness are promising systems for food smart packaging. This research aimed to develop a smart color film for food packaging using gelatin/hydroxypropylmethyl cellulose (HPMC) and red beet betalain. In this study, edible films with different ratios of gelatin to HPMC were prepared successfully, and the ratio of 3:1 was determined as optimal samples based on water vapor permeability (WVP) and mechanical properties. Betalain with different concentrations was then added to the optimal film, and the physical and mechanical properties of the resulting films were evaluated. Also, TVB-N test to assess their ability to detect beef meat and shrimp spoilage was studied. The addition of betalain improved the solubility, WVP, mechanical properties, and 2,2-diphenyl-l-picrylhydrazyl free radical scavenging activity of the film. As a final point, the incorporation of betalain into the gelatin/HPMC films can be used to indicate the freshness of food.

Authors:Cengiz Caner, Çiğdem Uysal Pala, Muhammed Yüceer Abstract: Food Science and Technology International, Ahead of Print. Effectiveness of ozone concentrations (2, 5, and 10 ppm) and exposure time (3 and 9 min) on selected physicochemical properties (pH, soluble solids, color values (L*, a*, and b*), and texture) and health-promoting indicators such as organic acids, total phenolics (TP), and anthocyanins of “Angelino” fresh plums was evaluated during storage (0, 30, 90, and 120 days) in equilibrium modified atmosphere packaging (EMAP). Total anthocyanin contents and organic acid profiles were significantly affected by storage times. Malic acid (MA) was the main organic acid in “Angelino” plums. MA content (4663 and 4764 mg/L) was the highest value in the ozonated 2-ppm/9-min and 5-ppm/3-min than other ozonated groups and also control at 120 days of the storage. The ozone treatments especially 2-ppm/9-min and 5-ppm/3 min can significantly retard the degradation of MA content (8294 to 2688–2694 mg/L) during the storage (p Citation: Food Science and Technology International PubDate: 2024-07-22T12:52:45Z DOI: 10.1177/10820132241263198

Authors:Purificación García-Segovia, Zaida Natalia Uribe-Wandurraga, Marta Igual, José Luís Mullor, Javier Martínez-Monzó Abstract: Food Science and Technology International, Ahead of Print. A growing market for seaweed products has emerged in the last 20 years, with microalgae and their extracts representing a source of high-value chemicals. In this study, antioxidative and anti-inflammatory activities of lipid fraction extract from Chlorella vulgaris (Chlorella) and Arthrospira platensis (Spirulina) on Normal Human Dermal Fibroblasts (NHDF cells) were evaluated. Treatments with Chlorella and Spirulina lipid extracts in NHDF cells at 0.1, 0.5, and 1% significantly protect UVA-induced damage by decreasing oxidative stress in the form of reactive oxygen species (ROS) but do not display any significant protection from HEV-induced damage. Chlorella or Spirulina lipid extracts at 0.1 and 0.5% display significant anti-inflammatory effects by inhibiting the 2-propanol-induced IL-6 expression on NHDF cells in vitro but showed no decrease in TNF-α expression. Chlorella and Spirulina lipid extracts present antioxidant and anti-inflammatory activity on NHDF cells.

Authors:Vijay Shankar Kushwaha, Shubhangi Srivastava, Prashant Pandharinath Said Abstract: Food Science and Technology International, Ahead of Print. The investigation was conducted to optimize process variables to manufacture functional pasta from composite flour. The selected grains were steeped, germinated, dried, and milled to produce flour. The flours were mixed at optimized proportions (57.31% buckwheat flour, 12.68% finger millet flour, and 30% paheli dal flour) to produce composite flour. The full factorial experimental design opted for optimization of process variables namely, moisture content (mc) (28, 30, 32, and 34%) and mixing speed (60, 80, 100, and 120 rpm). The optimized multi-grain pasta showed shorter processing time, in-range cooking loss, and higher cooking weight and water absorption capacity (WAC). The highest overall acceptability was recorded for multi-grain pasta processed at 60 rpm with an initial mc of 32%. Proximate analysis of optimized multi-grain pasta showed that pasta contained protein (13.95%), crude fiber (5.05%), ash (2.05%), a lower amount of fat (0.74%), and carbohydrates (71.71%).

Authors:Samsul Rizal, Maria Erna Kustyawati, Murhadi, Reka Kumala Sari, Rahmat Hidayat Abstract: Food Science and Technology International, Ahead of Print. The combination of Saccharomyces cerevisiae and Rhizopus oligosporus liquid inoculum has been successfully used to ferment soybeans into tempeh that contains β-glucan. However, using the liquid inoculum of these two microbes as a starter is impractical; so, developing an instant tempeh dry inoculum in powdered form, called the Mosaccha inoculum powder, for ease of use is necessary. This study aimed to determine the best concentration of instant Mosaccha inoculum powder to produce high-quality Mosaccha tempeh. The study used a Complete Randomized Block Design with seven different levels of instant Mosaccha inoculum powder percentage, ranging from 0.3% to 1.8% (w/w). A commercial tempeh inoculum, RAPRIMA, amounting to 0.2%, was used as control. Then, the microbiological (total mold and total yeast) and sensory (color, aroma, texture, and taste) properties were evaluated. The data obtained was analyzed statistically using analysis of variance (ANOVA) and Honestly Significant Difference (HSD) tests at the 5% level. The results showed that the percentage of instant Mosaccha inoculum powder significantly affected the microbiological and sensory properties of Mosaccha tempeh. A concentration of Mosaccha inoculum powder between 0.6% to 1.8% could produce good quality Mosaccha tempeh, but the best Mosaccha tempeh was produced with 1.5% instant Mosaccha inoculum powder, which met the Indonesian National Standards (SNI) 3144:2015, had a very favorable taste, and contained 0.49% β-glucan. Therefore, Mosaccha inoculum in powdered form can be developed and used as a starter in making high-quality tempeh that contains β-glucan.

Authors:Soutrick Paick, Rahul Das, Masud Alam, Anamika Sharma Abstract: Food Science and Technology International, Ahead of Print. Corn silk, often considered as a waste material in sweet corn processing, is typically discarded by most food manufacturing industries. This study aims to maximize the utilization of corn silk by evaluating its phytochemical, physicochemical and sensory characteristics. The development of food products with enhanced nutritional value is a pressing concern for both scientists and food producers in the industry. Therefore, this research focuses on the creation of highly nutritious muffins incorporating underutilized corn silk powder (CSP). In the muffin preparation, CSP was used to partially replace refined wheat flour at levels of 10%, 20%, 30% and 40%. As the proportion of CSP increased, the protein and crude fiber content of the muffins gradually increased. Additionally, the total phenolic content and antioxidant activity of the muffins significantly increased (p ≤ 0.05) with the inclusion of CSP, reaching their maximum values when CSP was used to replace 40% of the refined wheat flour. The incorporation of CSP led to a decrease in the L* (lightness) value, resulting in lower a* (redness) and b* (yellowness) values in the muffins. Texture analysis revealed that the cohesiveness, chewiness and gumminess of the muffins increased as the amount of CSP in the recipe was raised. A sensory evaluation was conducted to assess the acceptability of the corn silk muffins. The addition of CSP in muffins improved the sensory characteristics including colour, aroma, mouthfeel, texture and overall acceptability. These findings indicate that CSP has the potential to be used in the development of bakery food products, instant mixes, infant food formulas and value-added items.

Authors:Nathalia Aparecida Barbosa Lossolli, Magali Leonel, Sarita Leonel, Maiqui Izidoro, Hebert Teixeira Cândido, Jaciene Lopes de Jesus Assis, Luciana Alves de Oliveira Abstract: Food Science and Technology International, Ahead of Print. Mangoes contain several components that are beneficial for health, in addition to being potential sources of starch for the food industry. However, a substantial amount of fruit is lost in the field because it does not meet commercial standards, resulting in food losses and environmental damage. Herein, the physicochemical properties of mango flours and starches obtained from different parts of the fruit of two cultivars were evaluated. Mango peel flours have higher levels of proteins, fibers, minerals, carotenoids, ascorbic acid, and antioxidant activity than pulp flours, in addition to a higher yellowing index and water and oil-holding capacity, and can be used as a functional flour. The pulp flours, with the higher starch content, showed characteristics that make them valuable as a potential ingredient in soft baking and gluten-free products. Mango starches have circular and oval shapes, with a bimodal distribution. All starches showed an A-type crystallinity pattern. Pulp starches showed a higher peak viscosity and breakdown, with a lower setback, and can be used as a thickening or gelling agent. The higher thermal stability of kernel starch suggests its application in sauces, baking, dairy products, and canned foods.

Authors:Yuqi Zhang, Xueyan Wei, Jiao Bao, Kang Xu, Xiaoyan Chen, Mengmeng Guo Abstract: Food Science and Technology International, Ahead of Print. Brewer’s spent grain (BSG), one of the main byproducts of brewing, has been widely used in the food industry due to its high nutritional components of dietary fiber, proteins, polysaccharides, and polyphenols. This study investigated the influence of wheat brewer's spent grain (WBSG) on the physicochemical properties of dough and steamed bread-making performance. The incorporation of WBSG in wheat flour significantly increased water absorption, development time, and degree of softening while decreasing the stability time of blending dough. Excessive WBSG up to 20% restricted the dough formation. WBSG contributed to the remarkable increase of pasting viscosities, pasting temperature, and immobilized water proportion in doughs. For all doughs, storage moduli (G′) were higher than viscous moduli (G″). WBSG addition resulted in higher moduli values and the formation of highly networked gluten structure, finally leading to the lower specific volume, spread ratio, and elasticity of bread. Lightness (L*) of bread decreased with increasing WBSG while redness (a*) and total color difference (ΔE) augmented. Low WBSG addition (≤5%) could endow steamed bread with the appearance of a chocolate-like color and pleasant malt flavor, which is acceptable for most consumers. Nevertheless, the improvement of nutritional and functional characteristics of steamed bread incorporated with WBSG should be more focused in the future.

Authors:Ranúsia Maria de Melo Lopes, Cristiani Viegas Brandão Grisi, Jorge Luiz Santos de Almeida, Janiele Ferreira da Silva, Camila Sampaio Mangolim, Solange de Sousa, Leonardo Augusto Fonseca Pascoal Abstract: Food Science and Technology International, Ahead of Print. The objective of this work was to evaluate the effects of the replacement of nitrite by natural antioxidants from black garlic (BG) on the quality parameters of jerked beef meat with pork for 60 days. Four formulations were prepared: control, 0.02% of sodium nitrite in brine curing, w/v (CON); 1.5% BG in brine curing, w/v (ASU); 1.5% BG in dry curing, w/w (ASS); and 1.5% of BG in the brine curing, w/v and 1.5% of BG in dry curing, w/w (ASUS). Nutritional composition, pH, water activity, shear force, fatty acid profile, color, and oxidative stability of the formulations were analyzed. The addition of BG did not affect the nutritional composition, pH, water activity, shear force, and fatty acid profile. On the other hand, it resulted in lower weight loss after centrifugation and lower values of L* and a*. TBARS values from the 30th day of storage were lower in the ASUS formulation, while carbonyl compounds at all times were lower than in the CON formulation. Results suggest that BG was an efficient alternative to nitrite in controlling protein oxidation during storage. Thus, the use of pork for the manufacture of jerked beef can be an alternative, and black garlic can be applied as a natural additive to the replacement of nitrite. In addition, black garlic was efficient in improving the oxidative stability of the jerked beef meat with pork.

Authors:Neeharika B, Vijayalaxmi K G, Shobha D Abstract: Food Science and Technology International, Ahead of Print. The germinated clove basil (Ocimum gratissimum) and sweet basil (Ocimum basilicum) seeds being a potent source of dietary fibre, minerals and antioxidants are utilized as functional ingredients for the enrichment of gluten-free pasta. The germinated clove basil seed and sweet basil seed incorporated pastas with acceptable sensory scores were developed by substituting 30% and 15% of gluten-free flour respectively. Basil seed pastas exhibited lesser cooking time (7–8 min), cooking loss (6%) and similar texture as that of control. The clove basil seed pasta exhibited better cooking quality, nutritional and antioxidant properties than the sweet basil seed pasta due to higher level of basil seed flour substitution. Consumption of one serving of clove basil seed pasta (75 g) could meet the dietary fibre (49%, 58%), protein (15%, 17%), magnesium (18%, 21%), phosphorus (22%, 22%), manganese (28%, 28%) and copper (28%, 28%) daily requirements of sedentary adult men and women, respectively.

Authors:IşılBarutçu Mazı Abstract: Food Science and Technology International, Ahead of Print. This study was conducted to determine the variation in the chemical composition of flours derived from Locusta migratoria at two distinct developmental stages: the fourth instar and adult stages. Adult locust flour exhibited approximately two times higher fat content, similar protein content, ash content, CHNS elemental composition, and 45.7% lower total phenolic content compared to fourth instar locust flour. The flour from the adult locust was lighter, more red, and yellow than the fourth instar locust flour. Nineteen fatty acids were detected in both flours, with oleic acid, palmitic acid, and linoleic acid being the major ones. The ΣPUFA/ΣSFA of fourth instar and adult locusts was 0.82 and 0.78, respectively. The ratio of ω-6/ω-3 fatty acids was 2.1 for the fourth instar locust flour and 1.7 for the adult locust flour. Apart from gamma-aminobutyric acid (GABA), similar amino acids were found in both the flours. However, significant differences were detected in the levels of some of these amino acids between the fourth instar and adult locust flours. Of particular interest, adult locust flour showcased a GABA content of 25.4 mg/100 g dry weight, making it a valuable alternative protein source in developing innovative and nutritious food products.

Authors:Nalla Bhanu Prakash Reddy, Perumal Thivya, Sugumar Anandakumar, Vincent Hema, Vadakkepulppara Ramachandran Nair Sinija Abstract: Food Science and Technology International, Ahead of Print. Tender coconut water (TCW) is a natural drink rich in natural electrolytes, minerals, salts and sugars; it has good health benefits. But, its shelf-life is very limited because of the active nature of enzymes present in it when exposed to air. Therefore, the processing of TCW is necessary to inactivate the enzymes. So, this study aims to observe the effect of various process parameters of pulsed electric field (PEF) on the quality parameters of TCW. For the treatment of TCW with PEF, a full-factorial design of experiments was followed with process parameters such as three levels of electric field intensity (8, 12, and 16 kV/cm), two levels of pulse width (PW) (50 and 70 μs), and six levels of the number of pulses (2000 to 12,000 pulses) were considered at a constant pulse OFF time of 75 ms. PEF treatment did not significantly change pH, total soluble solids, and viscosity. However, it significantly affected vitamin C, colour, and total and reducing sugars. PEF treatment significantly enhanced the total phenolic content and antioxidant activity by 23.17% and 42.49%, respectively. At the same time, significant inactivation of polyphenol oxidase (100%) and peroxidase (60.2%) was observed at PEF treatment conditions of 16 kV/cm, 70 μs PW, and 12,000 pulses. Moreover, no significant change in the sensory acceptability of PEF-treated TCW (16 kV/cm, 70 μs PW, 12,000 pulses) when compared to the untreated/fresh TCW, which is a promising sign.

Authors:Julia Nutter, Amelia Ivone Saiz Abstract: Food Science and Technology International, Ahead of Print. Chemical oxidizers and redox enzymes have traditionally been used to enhance the quality of baked goods. However, consumers now seek natural and clean-label ingredients, avoiding those with chemical-sounding names. Honey, a natural source of glucose oxidase (GOX), represents a promising alternative to purified enzymes for baking purposes. This study aimed to evaluate the effect of honey on the molecular structure and microstructure of gluten proteins in sourdough fermented by different lactic acid bacteria (LAB) strains. Four wheat-rye (1:1) sourdoughs were prepared, each supplemented with honey and inoculated with a different LAB strain. Additionally, two uninoculated doughs, one with honey (honey dough) and the other without (control dough), were prepared under identical conditions. Electronic paramagnetic resonance spectroscopy revealed the presence of hydrogen peroxide in honey solutions, indicating its role as an active source of GOX. Raman spectroscopy showed that honey addition altered the molecular structure of gluten by increasing the proportion of random coils at the expense of α-helix structures. This change is likely attributed to the competition between honey sugars and gluten proteins for water molecules in this system. Moreover, honey led to a decrease in the free sulfhydryl content of gluten compared to the control dough, suggesting an increase in disulfide crosslinking points. These enhanced protein–protein interactions were observed in scanning electron microscopy micrographs as a coarse gluten network composed of interconnected strands and fibrils. All LAB strains exhibited optimal acidification (pH Citation: Food Science and Technology International PubDate: 2024-05-13T07:56:27Z DOI: 10.1177/10820132241252252

Authors:Blen Girma, Asnake Desalegn, Dagim Jirata Birri, Mogessie Ashenafi, Fitsum Tigu Abstract: Food Science and Technology International, Ahead of Print. Ethiopian honey wine, Tej, is the most popular traditionally fermented alcoholic beverage in Ethiopia. Owing to the spontaneous fermentation process, the final product is neither predictable nor consistent in quality. Attempts have not been made before to solve this problem. Thus, the aim of this study was to develop a potential mixed starter culture of yeast and lactic acid bacteria isolated from Tej samples for the production of Tej with consistent quality. One hundred seventy-seven lactic acid bacteria and 194 yeasts were isolated from 30 Tej samples collected from southwest Ethiopia. After sequentially testing the isolates towards physiological stress tolerance and desired metabolic products, 10 lactic acid bacteria and 10 yeast isolates were screened. Later, four lactic acid bacteria and four yeast isolates were found to be compatible in co-culture tests. Finally, the combination of lactic acid bacteria and yeast isolates was formulated using the design of expert version 7.0.0 software, and six formulates (F #1–6) were designed. Controlled Tej fermentation was performed under laboratory conditions using six lactic acid bacteria–yeast starter culture formulations. The sensory attributes, in terms of color, flavor, odor, turbidity, and overall acceptance analysis scored 4.8/5.0 (F #2) and 4.7/5.0 (F #6), with mean significant variations (p Citation: Food Science and Technology International PubDate: 2024-05-08T06:18:24Z DOI: 10.1177/10820132241251866

Authors:Junior Bernardo Molina-Hernández, Margarita Maria Andrade-Mahecha, Hugo Alexander Martínez-Correa Abstract: Food Science and Technology International, Ahead of Print. In recent years, people have become interested in consuming low-fat foods as this reduces the risk of obesity and cardiovascular disease. For this reason, this study optimized the incorporation of passion fruit epicarp (PFE) as a partial fat substitute in dairy ice cream. For this purpose, a central composite rotational design 22 was performed and 5 response variables were optimized, of which 4 variables were maximized (percentage overrun, hardness, adhesiveness, and color coordinates L*, a*, b*), while the melting rate was minimized as a function of two factors (% PFE and % fat). The stability of three types of ice cream was then evaluated: experimental ice cream (3% milk fat and 0.97% PFE), commercial ice cream (4% milk fat and 2% vegetable fat) and control ice cream (3% milk fat without PFE added), according to their physicochemical and sensory properties during 57 days of storage (−22 °C, 85% relative humidity). The results showed that it was possible to reduce the milk fat by up to 25% by adding PFE (0.97%), which significantly reduced the melting rate and resulted in higher hardness (N), adhesiveness and increased yellowness compared to the commercial samples. The optical microscopy analysis also showed that PFE keeps the air bubbles immobile due to the increased viscosity in the serum phase during the 57-day storage.

Authors:Fundagül Erem Abstract: Food Science and Technology International, Ahead of Print. This study aimed to investigate the properties of buckwheat flour-based gluten-free muffins formulated by using corn flour (CF), Spirulina powder (SP), and buffalo yogurt (BY) levels as the factors in the Box-Behnken experimental design. The color values, total soluble polyphenol content (TPC), radical scavenging activity (RSA), specific volume, moisture content, and baking loss results were evaluated as the response variables in the design. The buckwheat flour in the control sample was substituted with CF and SP. Cow yogurt was used in the control muffin instead of milk and was substituted with BY at different levels in other samples. Among the response variables, TPC and RSA values were selected for the optimization studies. Decreasing the CF and SP levels in the formulations resulted in observing higher TPC and RSA values. Three optimal formulations were obtained by response surface methodology. Both cow and buffalo yogurt did not change the properties of the muffins adversely compared to milk. Increasing the SP content made the muffins firmer and caused a decrease in the L*, a*, b*, and browning index values of the muffins. However, sensory scores of SP-containing muffins were also satisfactory. Citation: Food Science and Technology International PubDate: 2024-04-27T06:19:54Z DOI: 10.1177/10820132241248486

Authors:Sibel Bölek, Feyza Tosya, Feriha Göksu Abstract: Food Science and Technology International, Ahead of Print. Tarragon has a great potential to be a healthy functional food ingredient thanks to its rich antioxidant, phenolic compounds, and nutrient content. The possibility of enriching bread with tarragon was investigated. For this aim, tarragon powder was used at the rates of 0, 2, 4 and 6% instead of wheat flour. In this study, the effects of substitution on the rheological properties of bread dough and color, total phenolic content, antioxidant activity, texture, sensory, and Fourier transform infrared (FT-IR) analysis of bread samples were performed. The composition of tarragon powder showed significant protein (23.16%), crude fiber (7.4%), antioxidant (48.22 ± 0.11%), and total phenolic content (511.66 ± 1.56 mg GAE/100 g). Bread samples with increased fiber and protein content were obtained by adding tarragon powder to the bread formulation. The major differences in the FT-IR absorbance spectra for the bread samples were not observed. Additionally, tarragon powder significantly increased the antioxidative properties of breads (p Citation: Food Science and Technology International PubDate: 2024-04-23T08:17:18Z DOI: 10.1177/10820132241248483

The study aimed to investigate the effect of thermal and non-thermal processing on the physicochemical, microbial, and sensory characteristics of king coconut water. King coconut water samples were subjected to ultrasonication (50 kHz, 30 min at 35 °C), microfiltration (0.5 µm), and thermal treatments (at 90 °C for 10 min) with sodium metabisulfite (0.1 g/L) except the fresh sample (control). Samples were tested for physiochemical, microbial, and sensory parameters. Storage studies were conducted at 4 °C for 28 days. pH, titratable acidity, and total sugar of all treated samples were within the Sri Lankan Standard (SLS) limit (4.6–5.5, 0.07–0.1%, 4.1–6.5%, respectively) during the 28 days of storage. Sodium metabisulfite addition was significant in lowering the browning index. Antioxidant and phenolic contents of microfiltered and ultrasonicated samples varied between 49%–65% and 2.5−2.8 GAE mg/100 mL, respectively, during 4 weeks of storage, which was significantly higher compared to the heat-treated samples. Sensory evaluation scored the lowest attribute values for thermally treated samples. Microbial analyses indicated that microfiltered and ultrasonicated king coconut water remained safe for consumption for up to 4 weeks. Ultrasound and microfiltration, with the integration of sodium metabisulfite, were identified as effective methods for processing king coconut water while preserving its wholesome properties.

Amir Hossein Elhami Rad, Mohammad Armin Abstract: Food Science and Technology International, Ahead of Print. This study aimed to develop a protein-fiber-rich extruded product based on yellow lentil, quinoa, and pumpkin flours. The final product quality is affected by formulation and extrusion parameters. Therefore, the effect of the pumpkin-flour ratio (A: 25–75%) and feed moisture content (C: 14–22%) besides barrel screw speed (B: 120–180 rpm) on the physical attributes of extrudates was investigated. Box–Behnken experimental design and stepwise-response surface method were used to analyze the effects of various process variables and ingredients on extrudates. The pumpkin-flour ratio had a significant positive correlation with bulk density (BD), water solubility index (WSI), and oil absorption index. Whereas the correlation between pumpkin-flour ratio with hardness, porosity, expansion ratio (ER), and water absorption index (WAI) was negative (P Citation: Food Science and Technology International PubDate: 2024-04-01T06:49:12Z DOI: 10.1177/10820132241243240

Authors:Miona Belović, Aleksandra Torbica, Vesna Vujasinović, Goran Radivojević, Lidija Perović, Jelena Bokić Abstract: Food Science and Technology International, Ahead of Print. High dietary fibre cookies were manufactured from non-wheat (triticale, spelt and rye) flours with apple, beetroot and pumpkin pomace powders added as natural colourants. Cookies were characterized by nutritional composition, colour, texture and sensory profile and subjected to a 2-month shelf-life study. Additionally, an acceptability study was done to determine consumers’ acceptance of cookies. Cookies prepared from rye flour and pumpkin pomace, as well as cookies prepared from spelt flour and beetroot pomace, can be labelled as ‘high fibre’ (dietary fibre content of 8.90% and 7.09%, respectively), while cookies prepared from triticale flour and apple pomace can be labelled as a ‘source of fibre’ (dietary fibre content of 4.50%). No obvious trend in the colour of cookies was observed after storage at room temperature and 40 °C, indicating the stability of natural colourants. Hardness decrease was observed in all samples after storage; however, the acceptability study showed that consumers prefer softer cookies. Sensory analysis showed that there were no signs of rancidity in samples after storage. Although triticale flour and apple pomace sample received the highest liking scores for appearance, odour and taste, all samples had liking ratings higher than 4 (indifferent) and can be further modified to satisfy consumers’ demands.

Authors:Batuhan Bursa, Huri İlyasoğlu Abstract: Food Science and Technology International, Ahead of Print. The demand for gluten-free foods has increased due to health-based issues and lifestyle choices. This study aimed to develop a gluten-free cookie with enhanced nutritional value. For this reason, the composite flour from corn flour (CF) and lentil flour (LF) was prepared for cookie formulation. To eliminate the possible negative impact of LF on the sensorial properties of the cookie, lemon peel powder (LPP) was incorporated into the cookie formulation. The effects of the LF level of composite flour and the incorporation level of LPP on the physical, textural, and sensorial properties of the cookie were investigated via response methodology. The optimal levels were found as 16 g LF and 1 g LPP for 100 g composite flour. The physical, textural, and sensorial properties, proximate composition, vitamin C and total phenolic contents, and antioxidant capacity of the developed cookie and control cookies were determined. The developed cookie had a higher nutritional value than the control cookie made from CF in terms of protein, dietary fibre, ash, and vitamin C. Moreover, it presented higher total phenolic content and radical scavenging activity. According to these results, the developed cookie can be proposed for a gluten-free diet.

Authors:Cem Baltacıoğlu, Oktay Keskin, Hande Baltacıoğlu, Erdal Ağçam Abstract: Food Science and Technology International, Ahead of Print. In this study, powder colorant was obtained from red cabbage (Brassica oleracea L.). The stability of the colorants obtained by spray and freeze drying was investigated in terms of antioxidant capacity and anthocyanin content. The yield of the products increased with the encapsulation for both drying methods and encapsulation application. Drying method and encapsulation application had a significant effect on most of the physical properties of powders except for flowability and adhesiveness values. An increase in L*, a*, and C values was observed with the encapsulation process. Antioxidant activity of the samples increased with the encapsulation process by 13.44% in the spray-dried samples, while it increased by 9.75% in the freeze-dried samples. Total monomeric anthocyanin content was detected as 9039.21 mg/kg for encapsulated freeze-dried samples and 7811 mg/kg for encapsulated spray-dried ones. Nine anthocyanins were detected in the samples by using high-performance liquid chromatography. To discriminate samples according to drying methods with/without encapsulation principal component analysis (PCA) was used based on the Fourier transform infrared (FTIR) data. Four groups were observed for the PCA. The chemometric evaluation was done to predict the antioxidant capacity, anthocyanin content, and individual anthocyanins using FTIR spectra. High correlations were observed between the calculated and reference values for partial least square regression analysis.

Authors:Supriya Priyadarsani, Priyadarsini Sanghamitra, Gaurav Kumar, Nabaneeta Basak, Sutapa Sarkar, Krishnendu Chattopadhyay Abstract: Food Science and Technology International, Ahead of Print. The first high-protein rice variety of India, CR Dhan 310, developed at ICAR-NRRI, Cuttack is being selected for the study. It contains 10.1% protein in milled rice as compared to 6–7% protein content in the milled rice of any other normal variety. It has intermediate amylose content (25.1%), medium bold grains rich in protein (10.1%) The significant changes in properties of raw and parboiled rice on processing were studied at statistical differences of p ≤ 0.05. These properties included physical, optical, antioxidant and rheological properties which changed with different processing techniques. All the three processes namely, puffing, popping and flaking increased the dimensions as compared to the raw rice. Peak viscosity measurements demonstrated the breakdown of starch molecules, with white rice having the greatest value (4145 cP) and popped rice having the lowest value (2017 cP) as a result of the starch granules being gelatinized during the production of popped rice. Highest anthocyanin content (2.93 mg/100 g) was observed in puffed rice, phenolic content (347.93 mg/100 g) was highest in popped rice and flaked/flattened rice showed highest flavonoid content (127.12 mg/100 g) indicating that tertiary processing of rice obtained higher values of phytochemicals when compared to the plain high-protein rice. This indicates that the processed products of rice can be consumed directly as ready-to-eat or can be used in preparation of other functional foods to combat malnutrition and build nutritional security. The study indicates that processing could improve the nutritional quality of the rice products.

Authors:Faezeh Sadat Aliakbari, Mahboobeh Kashiri, Behrouz Ghorani, Morteza Khomeiri, Seid Mahdi Jafari Abstract: Food Science and Technology International, Ahead of Print. Using barberry (Berberis vulgaris L.) as a natural dye in combination with electrospinning technology represents a promising approach for the development of intelligent packaging systems. In this study, the influence of different concentrations of zein (16, 18, and 20%) and barberry anthocyanin-rich powder (BARP) (16, 18, and 20%) on the surface tension and rheological properties of the solution were evaluated. The most favorable nanofibers (NFs) were obtained from a solution containing 18% (w/w) zein under constant voltage. The surface morphology, size, and color-changing properties of electrospun NFs derived from zein polymers containing different concentrations of BARP (16, 18, and 20%) under various electrical fields (20, 22, and 24 kV) were evaluated. The Fourier-transform infrared spectroscopy analysis confirmed the interaction of BARP within the zein-based NFs. The results indicated that the concentration of BARP had a noticeable impact on the physicochemical properties of the NFs. Furthermore, efficacy of the appropriately fabricated halochromic label was evaluated for monitoring the packed rainbow trout fillet during refrigerated storage. On the 10th day, a noticeable visual color turned from pink to pale yellow was observed in response to pH variations. Additionally, the TVN value confirmed the effectiveness of halochromic electrospun labels for non-invasive assessment of fish fillet quality.

Authors:Cengiz Caner, Kübra Tiryaki, Çiğdem Uysal Pala, Muhammed Yüceer Abstract: Food Science and Technology International, Ahead of Print. This research focuses on the effectiveness of electrolyzed water (50 and 100 ppm for 3 min), ultrasonication (80 W for 3 min), and their combinations on fresh strawberries, which are then packaged using microperforated film to enhance their storage stability. The gas composition in the headspace, pH, soluble solids, color (L*, a*, b*, and ΔE* values), anthocyanins, total phenolics, and texture profile was evaluated for the 35 days of storage at +4 °C. The lowest weight loss was measured at about 100 ppm electrolyzed water (EW; 0.47%), and the highest one was in the control group (0.57%) after storage. At the end of the storage, O2 in the headspace decreased from 20.90% to 10.50–8.10% and CO2 was accumulated from 0.03% to 16.4–14.34%. The results showed that soluble solids decreased (9.95 to 8.48–7.85 °Bx) and pH values increased (3.34 to 3.79–3.91) during storage. At the end of the storage, the total phenolics in the control group decreased by the most during storage (from 1209.09 ppm to 808.00 ppm), whereas the 50 ppm EW group had the highest (931.66 ppm). Further, the significantly highest anthocyanin amount was found to be 143.86 ppm in the 100 ppm EW group at the end of 28 days of storage. The EW can significantly delay the degradation of anthocyanin over the storage period. The sonication at 100 ppm EW damages strawberry tissues, reducing their hardness. The lowest decay rate was found in fruits treated with 100 ppm EW (41.67%), followed by 50 ppm EW (58.33%), compared to the control (75.00%). This study reveals that applications of the 50 ppm EW and also 50 pm EW combined with ultrasonication have great potential in the extending storage stability of the fresh strawberries.

Authors:Abdulaziz Yahya Al-Ghamdi Abstract: Food Science and Technology International, Ahead of Print. Foodborne microbial infections are leading cause of many deadly illnesses. As a result, there is an anticipated need for the development of innovative packaging materials with effective antibacterial potential. This article describes preparation and characterization of innovative ZnO@CeO2 nanocrystals through a facile hydrothermal method, as well as their outstanding antibacterial properties. The ZnO@CeO2 nanocrystals used were prepared using precursors zinc acetate and cerium nitrate at 180°C. Various sophisticated physicochemical parameters were used to assess nanocrystals. The antibacterial activity was examined using minimum inhibitory concentration technique against four major foodborne pathogenic bacteria, namely Staphylococcus aureus (Gram positive), Escherichia coli, Salmonella typhimurium and Klebsiella pneumoniae (Gram negative) at four distinct concentrations (0–400 µg/mL). The in vitro cell compatibility test was done on fibroblasts. According to our findings, the lowest concentration of ZnO@CeO2 nanocrystals limiting development of tested strains is 100 µg/mL. Additionally, the results show that the combination of ZnO and CeO2 can be synergistic, resulting in ZnO@CeO2 nanocrystals with enhanced antibacterial activity. To summarize, unique ZnO@CeO2 nanocrystals with a high surface-to-volume ratio with outstanding antibacterial activity and no harmful impact to mouse fibroblasts were shaped. The ZnO@CeO2 can be utilized to competently suppress microbial growth spoiling the food and could be utilized as economical and efficient future packaging material for food industries.

This study delves into an exploration of the antimicrobial and antibiofilm properties of the essential oils (EOs) of cinnamon, garlic, and onion on Salmonella Enteritidis. Firstly, disc diffusion and minimum inhibitory concentration (MIC) techniques were employed to assess the antibacterial activity of the EOs. Additionally, the study explored the effect of these EOs on both initial cell attachment and 24 h-preformed biofilms. The crystal violet assay was implemented to evaluate biofilm biomass. The findings revealed that cinnamon EO exhibited the highest anti-biofilm activity. Furthermore, initial cell attachment inhibition at MIC ranged between 50 and 65% for the three oils, while inhibition rates on preformed structures were lower than 40% for all EOs at this MIC concentration. The study also found that the effects of these oils were dosage- and time-dependent (p Citation: Food Science and Technology International PubDate: 2024-01-18T06:54:41Z DOI: 10.1177/10820132241227004

Authors:Marilia Silva Malvezzi Karwowski, Yasmine Sayuri Kassuia, Daniela Góes Turchenski, Ana Carolina Camargo de Oliveira Aust, Renata Ernlund Freitas de Macedo Abstract: Food Science and Technology International, Ahead of Print. This study aimed to assess the potential use of grains (amaranth, millet, and quinoa) as immobilizing matrices on the metabolic activity of Lactiplantibacillus plantarum and evaluate the viability of the probiotic immobilized in millet during simulated oro-gastrointestinal digestion (OGI) and storage. Firstly, different grains, sterilization and immobilization times were assessed. Secondly, Lp. plantarum was immobilized in millet and its viability and metabolic activity were assessed during non-refrigerated long-term storage and OGI. Metabolic activity was higher with 15 min. of grain sterilization and 72 h of immobilization. Lp. plantarum in millet showed the highest count. Millet grains were able to maintain the high population (>7 log CFU/g) and the metabolic activity of Lp. plantarum during up to 150 d of storage and conferred a protective effect on entrapped probiotic cells during OGI. Millet is a promising immobilizing matrix for the addition of probiotics in dry food products.
