  • Impact of vinification procedure on fruit wine inhibitory activity against
           α-glucosidase
    • Abstract: Publication date: October 2018Source: Food Bioscience, Volume 25Author(s): Uroš Čakar, Nađa Grozdanić, Boris Pejin, Vesna Vasić, Mira Čakar, Aleksandar Petrović, Brižita Djordjević α-Glucosidase inhibitory activity (AGL) of fruit wine samples made from blueberry, black chokeberry, blackberry, raspberry and sour cherry cultivars grown in Serbia was studied using an microvinification procedure. More precisely, both sugar and enzyme were added to the fruit must before fermentation for half of the samples. This increased the extraction of phenolic compounds. All the samples showed higher bioactivity compared to acarbose, the compound used as a positive control. Blueberry (IC50 ~27 ± 1 µg/ml) and black chokeberry (IC50 ~28 ± 1 µg/ml) wine samples had the highest values regardless of the vinification method. In addition to this, chlorogenic and caffeic acids were recognised as their key AGL bioactives. Taken all together, the fruit wine samples or their lyophilised extracts may be considered as complementary medicine supplements of potential interest for the control of postprandial hyperglycemia.Graphical abstractfx1
       
  • Encapsulation of glucose oxidase in alginate hollow beads to reduce the
           fermentable sugars in simulated musts
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Estefanía Ruiz, María D. Busto, Sonia Ramos-Gómez, David Palacios, María C. Pilar-Izquierdo, Natividad Ortega The treatment of must with glucose oxidase (GOX) is a biotechnological alternative to the production of reduced-alcohol wines. Nevertheless, the low pH of must is a limiting factor for the enzyme's activity. This study reports on a simple immobilization method that uses enzyme encapsulation to overcome that limiting factor. The encapsulation of GOX was acceptably optimized using response surface methodology (RSM). An immobilization yield of 73% was obtained with 22 g L−1 Na-alginate, 20 g L−1 carboxymethylcellulose, and 12 g L−1 CaCl2. The apparent Km value of the immobilized GOX (4.55 mM) was slightly higher than that of the soluble enzyme (3.99 mM) and the activation energy was similar (~ 35 kJ mol−1). The encapsulated enzyme maintained about 68% and 92% of its initial activity at pH 3.0 and 4.0, respectively. Moreover, GOX-loaded alginate hollow beads could be re-used with 7 reaction cycles in model must, with a final reaction efficacy of 37%. GOX was successfully encapsulated in Ca-alginate hollow beads, and their catalytic potential remained unaffected by the immobilization process. In view of these results and the activity of the immobilized enzyme at the acidic pH of the must, this encapsulated biocatalyst is a promising alternative for industrial use in the production of reduced-alcohol wines.Graphical abstractfx1
       
  • Characterization of phospholipids from Pacific saury (Cololabis saira)
           viscera and their neuroprotective activity
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Jing Zhang, Ningping Tao, Mingfu Wang, Wenzheng Shi, Binqing Ye, Xichang Wang, Qingcheng Zhu, Chuanxiang Hua Pacific saury (Cololabis saira) is an important marine commercial fish in the world. The crude Pacific saury viscera (PSV) phospholipids were extracted with supercritical carbon dioxide and organic solvent method using ethanol, yielding 24/100 g phospholipids and 21/100 g (dry weight), respectively. Their fatty acid profiles were obtained using gas chromatography. Docosahexaenoic acid (DHA) and palmitic acid were the major fatty acids. High-performance liquid chromatography equipped with an evaporation scattered light detector was used to quantitatively analyse the major component of the phospholipid extract. Phosphatidylcholine (89 mg/g), phosphatidylinositol (53 mg/g) and phosphatidylethanolamine (40 mg/g) were the main phospholipids, while phosphatidylserine, lysophosphatidylcholine and lysophosphatidylcholine were the minor phospholipids at 5, 15 and 19 mg/g, respectively. The inhibitory effects of PSV phospholipids and the PC fraction, obtained using silica gel column chromatography, on the secretion of amyloid beta (Aβ)1–42 in the supernatant of Chinese hamster ovary cells stably transfected with amyloid precursor protein and presenilin 1 were studied, with soybean phospholipids as the positive control. The results showed that, compared with the model control group, the Aβ1–42 was decreased 69% with PSV phospholipid, 62% with PC fraction and 36% with soybean phospholipids. Taken together, PSV phospholipids were rich in n-3 fatty acids, especially DHA, and may have potential for the treatment of neurodegenerative diseases such as Alzheimer disease.
       
  • The effect of plasticizers on the functional properties of biodegradable
           gelatin-based film: A review
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): N. Suderman, M.I.N. Isa, N.M. Sarbon Food packaging derived from a petroleum base represents a serious environmental problem. Finding alternative sustainable solutions is a must. Therefore, the current study has focused on the production of biodegradable food packaging from renewable materials, primarily gelatin. The effect of the biomaterials used on functional properties of the films produced needs thorough investigation. Gelatin represents interesting biomaterials for developing biodegradable food packaging, mainly due to their good film forming properties and abundantly in nature. However, the incorporation of gelatin in biodegradable films for food packaging may give some drawback on certain properties of the film such as tensile strength and water vapour permeability. Thus, addition of plasticizers into the film materials improves the functional properties of films by increasing their extensibility, dispensability, flexibility, elasticity, and rigidity. This study aims to review the current findings on how plasticizers impact the functional properties of biodegradable gelatin-based films. Plasticizers incorporation in the films may affect the continuity of the polymer matrix, leading to physical changes, where the films become more flexible and stretchable. Generally, the plasticization effect of plasticizers strengthens the film structure, in which the tensile strength and elongation of the films are improved and water barrier properties are reduced.Graphical abstractfx1
       
  • Biochemical evaluation of selected grape varieties (Vitis vinifera L.)
           grown in Jordan and in vitro evaluation of grape seed extract on human
           prostate cancer cells
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Tamam El-Elimat, Bara`a A. Jarwan, Aref Zayed, Ahmed Alhusban, Maha Syouf A chemical and biological approach was used for quality assessment of 16 different eating grape varieties collected in Jordan. A validated LC-ESI-MS/MS method was used for quantitative analysis of resveratrol in grape skin and grape seed extracts. Grape skin extracts showed higher resveratrol content than that of seeds. The antioxidant activity and total phenolic content of seed, skin, and whole berry extracts of the grape varieties were evaluated using the DPPH radical scavenging assay and Folin–Ciocalteu colorimetric method, respectively. Seed extracts showed the highest total phenolic content and antioxidant activity. The in vitro effects of Golden Scatt grape seed extract on human prostate cancer cell migration and colony-genic potential were assayed. Golden Scatt seed extract modulated the colony formation potential and inhibited the migratory potential of prostate cancer cells in a dose-dependent manner.Graphical abstractfx1
       
  • Process development of bottle gourd sweetmeat by microwave heating:
           Changes in rheological, textural, sensory and morphological parameters
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Suheela bhat, Charanjiv Singh Saini, Harish Kumar Sharma The effect of replacement of khoa-sugar mixture in bottle gourd sweetmeat (BGSM) with varying proportions of bottle gourd pomace (BGP) was studied. Rheology of preliminary mix, used for preparation of bottle gourd sweetmeat, was studied in order to predict the behaviour of final product under different processing conditions. Results showed that increase in temperature beyond 30 °C caused increase in elasticity (G′) of mix whereas decrease in temperature showed increase in viscosity (G″). Microwave heat dissipation process revealed that samples microwaved at low power (700 W) caused increase in temperature from 80 °C in 1 min to 112 °C in 5 min. Sweetmeat was heated until total solid content reached 85%. Heating time varied as a function of BGP and highest heating time of 5.32 min was required for BGSM containing highest BGP concentration (40%). Significant (p 
       
  • Feasibility of a pH driven method for maximizing protein recovery of
           over-salted albumen
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Manat Chaijan, Worawan Panpipat The feasibility of a pH-shift process for protein recovery and salt removal from over-salted albumen was evaluated. The effects of albumen to water ratios (1:0, 1:1. 1:3 and 1:5, w/w) and pH-shift versions (acid and alkaline processes and direct pI precipitation) on protein yield and salt reduction were also studied. The higher the ratio of water added the lower the protein yield obtained for all pH driven methods. The highest protein yield (31%) was found using the acid-shift process without extra water. However, salt removal efficacy from the protein isolate was improved by increasing water added. To enhance the protein recovery, several flocculants were used with the acid process. Maximum protein yield of 36% was obtained when κ-carrageenan was used. Doubly washing the protein isolate with cold water with vacuum filtration further increased salt removal (49%) with the lowest protein loss. Therefore, an acid pH-shift process with the aid of κ-carrageenan and post-washing had the best potential for recovering protein and eliminating salt from over-salted albumen. The optimum process can recover protein up to 31% with 74% salt removal. The chemical structure of protein isolate was negligible change as seen using sodium dodecylsulfate-polyacrylamide gel electrophoresis and Fourier transform infrared spectroscopy.Graphical abstractfx1
       
  • Effect of polyphenols from wild Chilean currants (Ribes spp.) on the
           activity of intracellular antioxidant enzymes in human gastric AGS cells
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Cristina Theoduloz, Alberto Burgos-Edwards, Guillermo Schmeda-Hirschmann, Felipe Jiménez-Aspee The protective effect of polyphenols from Chilean currants (Ribes spp.) in human epithelial gastric cells (AGS) against oxidative induced-stress has been recently reported. The aim of the present study was to assess the ability of polyphenol-enriched extracts (PEE) from three Chilean Ribes species to modify the activities of the intracellular antioxidant enzymes: catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GSH-R) and superoxide dismutase (SOD) in AGS cells. The PEE of each species was fractionated using membrane chromatography to give an anthocyanin-enriched fraction (AF) and a copigment fraction (CF). A significant increase in the SOD activity was observed with a dose-response effect after an overnight incubation of AGS cells with the PEE, AF and CF from the selected species. The activity of CAT was enhanced by the CF of Ribes magellanicum and R. cucullatum, and by the AF of R. punctatum. For the GSH-R, a dose-response effect was observed in the extracts of R. magellanicum, while for the GSH-Px activity, only the AF of R. magellanicum and R. cucullatum had a significant increase. The studied samples were not able to increase the intracellular GSH content. Only the R. magellanicum samples raised the intracellular total antioxidant activity. These results suggested that the increase in the activity of the antioxidant response enzymes is associated with the cytoprotective effect of these native currants.Graphical abstractfx1
       
  • Goat and cow milk powder-based diets with or without prebiotics influence
           gut microbial populations and fermentation products in newly weaned rats
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Gunaranjan Paturi, Christine A. Butts, Duncan Hedderley, Halina Stoklosinski, Sheridan Martell, Hannah Dinnan, Elizabeth A. Carpenter The influence of goat and cow milk powders individually and in combination with prebiotics (inulin and oligofructose) on gut microbial populations, organic acid concentrations and gut morphology were studied in newly weaned rats fed for 21 days. The abundance of bacterial populations such as the Bacteroides-Prevotella-Porphyromonas group, Bifidobacterium spp. and Lactobacillus spp. in the gastrointestinal tract (ileum, caecum or colon) of rats were influenced by goat and cow milk powder-based diets. Clostridium perfringens was decreased significantly (P 
       
  • Combined effects of plant and cell-free extracts of lactic acid bacteria
           on biogenic amines and bacterial load of fermented sardine stored at
           3 ± 1 °C
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Esmeray Kuley, Mustafa Durmus, Yilmaz Ucar, Ali Riza Kosker, Elif Tugçe Aksun Tumerkan, Joe M. Regenstein, Fatih Ozogul Effects of cell-free extracts (CFE, 8%) prepared using Lactobacillus plantarum FI8595 or Pediococcus acidolactici ATCC 25741 alone or in combination with thyme and laurel extracts (0.5%) on physical, sensory, microbiological and chemical quality of fermented and vacuum packaged sardine fillets were investigated during 8 wk of chilled storage (3 ± 1 °C). Sardine fillets were divided into 7 groups with the control being untreated. The other groups were treated with CFE of Lb. plantarum (LP group) and P. acidolactici (PA group). In addition, thyme with LP CFE (THLP) or PA CFE (THPA); and laurel with LP CFE (LALP) or PA CFE (LAPA) were also prepared. According to the sensory and physical assessment, shelf life of fermented fish was 5 wk for the control, 6 wk for LP, PA, LALP and LAPA, and 7 wk for THPA and THLP, although chemical and microbiological results exhibited longer shelf life. THPA and THLP had the lowest bacterial growth and TBA values. TVB-N values remained below 35 mg/100 g until 7 wk for all groups. THPA significantly reduced TMA formation. The study suggested that cell-free extracts of Lb. plantarum and P. acidolactici with thyme extract was the most effective way to improve the shelf-life of fermented sardines stored at chilled temperature.
       
  • Phytochemical characterization and antimicrobial evaluation of young
           leaf/shoot and press cake extracts from Hippophae rhamnoides L
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Vitalijs Radenkovs, Tõnu Püssa, Karina Juhnevica-Radenkova, Dea Anton, Dalija Seglina The chemical components, as well as antioxidant and antimicrobial activities of extracts derived from the young leaves/shoots and press cake of sea buckthorn (SBT) (Hippophae rhamnoides L.) were studied. The chemical analysis of the ethanolic extracts by liquid chromatography-mass spectrometry (LC-DAD-ESI-MS/MS) led to the identification and quantification of 20 individual hydrophilic compounds including phenolic acids, flavonols, flavan-3-ols, and proanthocyanidins. The results of this study imply that DPPH• radical scavenging of each polyphenol acts independently. The relative speed of the reaction depends predominantly on each compound's chemical structure rather than its concentration. The extracts from SBT leaves/shoots and press cake, dissolved in water after the removal of ethanol, showed a significant antimicrobial activity against Gram-positive aerobic or facultative anaerobic and Gram-negative pathogenic bacteria, which included Bacillus spp. and the Enterobacteriaceae family (Salmonella spp., Escherichia coli, Yersinia pestis, Klebsiella, and Shigella). The study confirmed that SBT extracts obtained using 20% EtOH are promising antimicrobial agents, their preparation is cost efficient, and uses neither toxic reagents nor any expensive extraction techniques. The analysis of microbiological contamination of chicken and pork meat showed that these samples could be stored for 72 h using accelerated spoilage conditions at 22 °C, and relative air humidity of 39%, and only slightly exceed limits for Enterobacteriaceae.Graphical abstractfx1
       
  • The effects of protein-phenolic interactions in wheat protein fractions on
           allergenicity, antioxidant activity and the inhibitory activity of
           angiotensin I-converting enzyme (ACE)
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Sana Gammoh, Muhammad H. Alu’datt, Mohammad N. Alhamad, Taha Rababah, Majdi Al-Mahasneh, Ahmad Qasaimeh, Ayman Johargy, Stan Kubow, Neveen M. Hussein Protein fractions were isolated from wheat flour including albumin, globulin, glutelin-1, glutelin-2 and prolamin. The free and bound phenolics were extracted from each protein fraction to determine the impact of their removal on allergenicity, antioxidant activity and the inhibitory activities of the angiotensin converting enzyme. The glutelin-1 fraction showed the highest protein content and yield of 71.02% and 21.02%, respectively. The highest antioxidant activity was noted in the glutelin-1 fraction (48.17%). The angiotensin converting enzyme inhibitory activities among the protein fractions ranged from 6.87% to 84.52%. The greatest reduction of allergenicity (39.66%) was demonstrated in the prolamin fraction. We conclude that the removal of phenolics appears to decrease significantly the allergenicity of wheat protein fractions while maintaining significant bioactivities related to anti-hypertensive, antioxidant, and anti-diabetic properties.Graphical abstractfx1
       
  • Functional properties of the enzyme-modified protein from oat bran
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Alexander Prosekov, Olga Babich, Olga Kriger, Svetlana Ivanova, Valery Pavsky, Stanislav Sukhikh, Yong Yang, Egor Kashirskih The protein concentrate was prepared from oat bran pre-treated with amyloglucosidase. The influence of amyloglucosidase on the efficiency of protein extraction and the functional properties of the resulting protein products were studied in comparison to the protein concentrate obtained by the conventional alkaline method. Samples, pre-treated with the enzyme, had a higher protein content (83.8%), control – 66.7%. Significant changes in the functionality of the protein product are associated with the hydrolysis of carbohydrates. Solubility, water retention and foaming capacity of product pre-treated with amyloglucosidase are higher. However, the oil-retaining capacity and stability of the foam of protein products of different methods of production did not possess a single trend.Graphical abstractfx1
       
  • Propyl gallate (PG) and tert-butylhydroquinone (TBHQ) may alter the
           potential anti-cancer behavior of probiotics
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Raziyeh Salmanzadeh, Morteza Eskandani, Ahad Mokhtarzadeh, Somayeh Vandghanooni, Roghaiyeh Ilghami, Hadi Maleki, Nazli Saeeidi, Yadollah Omidi The effects of antioxidant food additives on the anti-proliferative properties of probiotic bacteria and their subsequent effects on the growth of cancer cells were studied. Propyl gallate (PG) and tert-butylhydroquinone (TBHQ) were selected as the antioxidant, and Lactobacillus rhamnosus was used as the probiotic model. L. rhamnosus bacteria were exposed to PG and TBHQ and their resistance was assessed. Afterwards, the cell-free supernatants (CFS) of untreated bacteria (CFSU), PG treated bacteria (CFSP) and TBHQ treated bacteria (CFST) were isolated. The human colorectal adenocarcinoma cell line HT-29 was then exposed to isolated CFS and subjected to geno- and cytotoxicity assays and annexin V-fluorescein isothiocyanate (FITC) apoptosis/necrosis detection evaluation. The 3-(4,5-dimethylthiazol-2-Yl)-2,5-diphenyltetrazolium bromide (MTT) assay showed that CFSP and CFST were able to inhibit HT-29 growth with IC50 values of 70 and 120 μg/mL at 24 h, respectively, whereas CFSU showed no significant toxicity. DNA fragmentation was observed in the CFSP and CFST treated HT-29 cells, shown using 4′,6-diamidino-2-phenylindole dihydrochloride (DAPI) staining. An annexin V flow cytometry assay showed that the cells treated with CFSP and CFST resulted in 35% and 32% apoptosis, respectively. The qPCR results showed that the expression of pro-apoptotic caspase 9 gene was significantly increased in CFSP and CFST treated HT-29 cells compared with CFSU treated cells (P ≤ 0.05), whereas the expression of the pro-survival Bcl-xL gene was downregulated in the CFSP and CFST treated cells compared with CFSU treated cells (P ≤ 0.05). In conclusion, different food additives may affect the metabolomics of probiotics, which could subsequently influence human health.
       
  • Development and physico-chemical characterization of microencapsulated
           bifidobacteria in passion fruit juice: A functional non-dairy product for
           probiotic delivery
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Carolinne Odebrecht Dias, Júlia dos Santos Opuski de Almeida, Stephanie Silva Pinto, Fabiani Cristina de Oliveira Santana, Silvani Verruck, Carmen Maria Olivera Müller, Elane Schwinden Prudêncio, Renata Dias de Mello Castanho Amboni The aim of this study was to produce a powdered probiotic passion fruit juice, in order to develop a new non-dairy probiotic beverage. For this purpose, passion fruit juice added with Bifidobacterium animalis ssp. lactis BB-12 was microencapsulated by spray drying using maltodextrin and/or inulin as encapsulating agents. The microcapsules obtained were characterized in relation to their morphological, physical and thermogravimetric properties after spray drying. The viability of probiotic microorganism, as well as the powders’ moisture content, water activity, solubility and color were evaluated throughout 30 days of storage at 25 °C and 4 °C. The storage at 4 °C resulted in a better maintenance of probiotic viability throughout the storage period. During storage at 25 °C, the sample made only with maltodextrin showed loss of viability of the bifidobacteria while the sample made with inulin offered better protection to the encapsulated bacteria. The different carrier agents affected the morphology and the particle size of the microcapsules. All the probiotic juice powders had similar flow characteristics. The use of maltodextrin resulted in higher values for moisture content and water activity. Throughout storage, an increase in moisture content and water activity was noted for all the samples. All the powders showed high solubility indexes. An increase in luminosity and a concurrent reduction in b* values throughout storage was noted for all the juice powder formulations at both temperatures, but more markedly at 25 °C. The results of the thermal analysis showed that both encapsulating agents improved the stability of the passion fruit juice.Graphical abstractfx1
       
  • Ultrasonication effects on the phytochemical, volatile and sensorial
           characteristics of lactic acid fermented mulberry juice
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Emmanuel Kwaw, Yongkun Ma, William Tchabo, Augustina Sackle Sackey, Maurice Tibiru Apaliya, Lulu Xiao, Meng Wu, Frederick Sarpong The effects of ultrasonication (US) on phytochemical, volatile profile and sensory qualities of lactic-acid-fermented mulberry juice were studied. The juice was sonicated at 5.0 °C, 60 W and at varying pulsed frequencies and times (22 kHz for 10 min, 22 kHz for 20 min, 24 kHz for 10 min and 24 kHz for 20 min). It was observed that US significantly (p 
       
  • Hypoglycemic activity of Chenopodium formosanum Koidz. components using a
           glucose uptake assay with 3T3-L1 adipocytes
    • Abstract: Publication date: August 2018Source: Food Bioscience, Volume 24Author(s): Bo-Yang Hsu, Shih-Ying Pan, Liang-Yi Wu, Chi-Tang Ho, Lucy Sun Hwang Djulis (Chenopodium formosanum Koidz.) is a cereal plant native to Taiwan. In this study, the hypoglycemic activity of djulis was investigated using a glucose uptake assay with 3T3-L1 adipocytes. Dehusk seeds (SD) or husks (HD) of djulis were extracted using 6 solvents with different polarities (i.e., water, hexane, acetone, ethyl acetate, methanol and ethanol). The crude water extract of husk of djulis (WHD) showed the highest increase in glucose uptake with 3T3-L1 adipocytes. Thus, it was further separated by solvent partition, XAD-7 gel column chromatography, and HPLC. Two hypoglycemic components (P1 and P2) were isolated from WHD. They showed hypoglycemic activity at 5–10 ppm. P1 might have a synergistic effect with insulin. P2, however, did not enhance insulin-stimulated glucose uptake, which might mean it is an insulin mimic. The results suggested that djulis is a potential anti-diabetes functional food ingredient.

  • Continuous biosynthesis of geranyl butyrate in a circulating fluidized bed
           reactor
    • Abstract: Publication date: Available online 9 May 2018Source: Food BioscienceAuthor(s): Lu Wang, Gang Chen, Jing Tang, Miao Ming, Chengsheng Jia, Biao Feng The continuous synthesis of geranyl butyrate in organic solvent was studied. The Candida rugosa lipase(CRL) was firstly immobilized on weak-acidic macroporous cation exchange resin D151. The batch experiments indicated that the adequate acid/alcohol molar ratio was 1:1.5 and the reaction time was 3.5–4 h. Then the continuous synthesis was realized with immobilized Candida rugosa lipase in a circulating fluidized bed reactor(CFBR). A stable ester yield of 77% was achieved under optimal conditions: enzyme loading 8 g, expansion ratio 1.6, feed flow rate 0.07 ml/min and butyric acid concentration 75 mmol/l. The results provide the basis for the scale-up of the process.
