  • Vital parameters for high gamma-aminobutyric acid (GABA) production by an
           industrial soy sauce koji Aspergillus oryzae NSK in submerged-liquid
           fermentation
    • Abstract: Abstract In submerged-liquid fermentation, seven key parameters were assessed using one-factor-at-a-time to obtain the highest GABA yield using an industrial soy sauce koji Aspergillus oryzae strain NSK (AOSNSK). AOSNSK generated maximum GABA at 30 °C (194 mg/L) and initial pH 5 (231 mg/L), thus was able to utilize sucrose (327 mg/L of GABA) for carbon source. Sucrose at 100 g/L, improved GABA production at 646 mg/L. Single nitrogen sources failed to improve GABA production, however a combination of yeast extract (YE) and glutamic acid (GA) improved GABA at 646.78 mg/L. Carbon-to-nitrogen ratio (C8:N3) produced the highest cell (24.01 g/L) and GABA at a minimal time of 216 h. The key parameters of 30 °C, initial pH 5, 100 g/L of sucrose, combination YE and GA, and C8:N3 generated the highest GABA (3278.31 mg/L) in a koji fermentation. AOSNSK promisingly showed for the development of a new GABA-rich soy sauce.

  • Effect of ground ginger on dough and biscuit characteristics and
           acrylamide content
    • Abstract: Abstract Effect of different contents of ground ginger [0%, 1%, 3%, 5%, and 7% (w/w)] on flour quality, dough and biscuit characteristic and acrylamide content were investigated. Texture results showed that by adding 1% (w/w) ground ginger, hardness of dough, hardness and chewiness of biscuit decreased, which was beneficial for biscuit making. Moreover, the L* value of biscuit dropped while the a* and b* value rose with the increase of ginger contents, indicating darker, redder and yellower biscuits. Sensory score of biscuits became worse but acrylamide content reduced with the addition of ground ginger. The phenol hydroxyl group of gingerol played a more important role in the reaction of formation of acrylamide than the side chain. Finally, biscuit with 1% ground ginger content showed good texture, color and acceptable sensory evaluation, as well as lowering the acrylamide content by 6.2%.

  • Effect of sieved fractionation on the physical, flow and hydration
           properties of Boscia senegalensis Lam., Dichostachys glomerata Forssk. and
           Hibiscus sabdariffa L. powders
    • Abstract: Abstract This study aimed at evaluating the effect of successive grinding and sieving processes on the physicochemical properties of powders obtained from Boscia senegalensis seeds, Dichostachys glomerata fruits and Hibiscus sabdariffa calyxes. Plant powders were fractionated into four granulometric classes and their properties were compared to those of unsieved powders. Mean particle size exerted a significant influence (p < 0.05) on the plant powders properties. The smaller the particle size of the powder fraction, the higher the protein, lipid and ash contents and the lower the carbohydrate and fiber contents. The decrease in particle size increased particle sphericity and elongation and enhanced flowability of B. senegalensis and D. glomerata powders, whereas an inverse tendency seemed to be observed for H. sabdariffa powders. Water absorption capacity, water solubility index and dispersibility were improved for finer particles for all plants. Sieve fractionation is a novel approach for improving physicochemical properties of plant powders.

  • Manufacture and characterization of optimized red ginseng drinks
           containing herbal medicine extracts
    • Abstract: Abstract The optimum mixing ratio of red ginseng, herbal medicine extracts, and oligosaccharides for diabetic improvement was investigated and verified through animal experiments. Using the optimum mixing technique, 2% red ginseng extract, 15% oligosaccharides, and 83% herbal medicine extracts were determined to be optimal for red ginseng beverages. The taste was improved as the amount of red ginseng decreased and oligosaccharides increased, whereas antioxidative activity was increased with increased red ginseng. In the animal model in which streptozotocin was administered to BALB-c mice, the red ginseng administration group exhibited lower blood glucose than the diabetic control group, and the blood glucose level was lower in the herbal medicine and red ginseng extract administration group. Insulin concentration was slightly increased by the red ginseng beverage, and hepatotoxicity due to excessive intake of red ginseng beverages was not detected.

  • Effects of oleaster flour supplementation in total phenolic contents,
           antioxidant capacities and their bioaccessibilities of cookies
    • Abstract: Abstract In presented study total phenolic contents, antioxidant capacities and their bioaccessibilities from cookies supplemented with oleaster flour were investigated. Oleaster flours (OFs) were produced using two different methods (peeled oleaster flour: POF and unpeeled oleaster flour: UPOF) from two different genotypes. OFs were used to replace wheat flour in the cookie formulation (control) at the levels of 5, 10, 15, 20 and 25% (w/w). According to the results, enrichment of OFs clearly increased total phenolic contents, antioxidant capacities and bioaccessibilities of cookies. The highest bioaccessible antioxidant capacities (ABTS, CUPRAC, and FRAP) of the samples were obtained from cookie samples enriched with 25% UPOF-1. In conclusion, the increases in phenolic contents, antioxidant capacities, and bioaccessibilities from cookies supplemented with OFs suggest the potential enhancement of beneficial health effect of cookie due to increased content of bioactive compounds present in oleaster flour.

  • Simultaneous detection of fruit allergen-coding genes in tomato, apple,
           peach and kiwi through multiplex PCR
    • Abstract: Abstract Fruit allergies have become more common in recent years, and are now a serious health problem. In this study, a multiplex PCR assay was used to detect potential fruit allergens causing food allergy labeling in Korea. For the detection of these allergens, specific primer pairs were designed to amplify the allergen-coding genes Cyclophilin (tomato), Mdtl 1 (apple), Pru p 2.01A (peach) and Pectin methylesterase inhibitor (kiwi), and primer pair targeting the 18S ribosomal RNA gene was additionally used as an endogenous control. Primer specificity was assessed with 23 plant species. A mixture of DNA from the four fruits was serially diluted and used to determine the sensitivity of the multiplex PCR assay, which was approximately 0.08 ng. Eleven commercial fruit products were evaluated to verify the applicability of the multiplex PCR assay. This assay is expected to be a specific and efficient method for detecting fruit allergens in foods.

  • Physico-chemical characterization of protein fraction from stabilized
           wheat germ
    • Abstract: Abstract Wheat germ shows the highest nutritional value of the kernel. It is highly susceptible to rancidity due to high content of unsaturated fat and presence of oxidative and hydrolytic enzymes. In order to improve its shelf life, it is necessary to inactivate these enzymes by a thermal process. In this work the functional properties and some characteristics of the protein fraction of treated wheat germ were evaluated. Sequential extraction of proteins showed loss of protein solubility and formation of aggregates after heating. DSC thermograms showed that wheat germ treated for 20 min at 175 °C reached a protein denaturation degree of ~ 77%. The stabilization process of wheat germ affected significantly some functional properties, such as foaming stability and protein solubility at pH 2 and pH 8. Nevertheless, heating did not affect the water holding, oil holding and foaming capacity of protein isolates.

  • A human–food web–animal interface on the prevalence of food-borne
           pathogens (Clostridia and Enterococcus) in mixed veterinary farms
    • Abstract: Abstract In the present work, we addressed the impact of a human–food web–animal interface on the prevalence of food-borne pathogens in mixed farms of Tamil Nadu, India. We have isolated and identified six strains of Clostridium sp. and five strains of Enterococcus sp. from food and animal sources disposed near to the veterinary and poultry farms. Phylogenetic relationships of these strains were inferred from their homologies in 16S rDNA sequences and rRNA secondary structures. The strain PCP07 was taxonomically equivalent to C. botulinum confirmed by neurotoxin-specific PCR primers, followed by mouse bioassay. Other Clostridial and Enterococcal isolates have shown a phylogenetic similarity to the C. bifermentans and E. durans isolated from veterinary farms, respectively. Results of our study revealed that a human–food web–animal interface has influenced the disease incidence and prevalence of these isolates in the poultry to veterinary farms, where human food acted as a likely transmittance vehicle for their infections.

  • Understanding response surface optimization of medium composition for
           pullulan production from de-oiled rice bran by Aureobasidium pullulans
    • Abstract: Abstract Central composite rotatable design of RSM was used for the optimization of medium composition for pullulan production from de-oiled rice bran by Aureobasidium pullulans in shake-flask fermentations. The sugars from de-oiled rice bran were extracted in distilled water under moist steam pressure and the obtained de-oiled rice bran extract (DRBE) was used for the optimization of medium composition. RSM optimized medium components (DRBE sugars, 3.88%; yeast extract, 0.24%; (NH4)2SO4, 0.06%; K2HPO4, 0.57% (w/v), and pH, 5.22) supported 5.48% (w/v) pullulan production and 0.88 (A600/100) biomass yield. Coefficient of determination for pullulan production (0.99) and biomass yield (0.99) was close to 1.0 which justifies significance of model. Lack of fit for both responses was non-significant, which shows fitness of quadratic model. FTIR and NMR spectral attributes confirmed the structure of pullulan. XRD patterns verified the amorphous nature of pullulan. De-oiled rice bran was found as a potential substrate for pullulan production.

  • Effects of Maillard reaction on physicochemical and functional properties
           of walnut protein isolate
    • Abstract: Abstract In this study, the Maillard reaction (MR) of glucose was applied to improve the physicochemical and functional properties of walnut protein isolate (WNPI). The MR products (MRPs) were prepared with glucose at 0 h (MRP0), 1 h (MRP1), 2 h (MRP2) and 3 h (MRP3) heating at 95 °C. The Infra-Red spectrum showed reduction of amide and S–H functionalities in MRPs with complete intermixing of glucose in MRP3. Scanning electron microscopy indicated changes in the morphology of MRP3 which also exhibited promising antioxidant effect. Significant decrease (P < 0.05) in hydrophobicity values (Ho) and increase (P < 0.05) in emulsifying activity/emulsifying stability indexes values were observed for MRPs. Uniform droplet distribution was observed in microscopy of emulsions while an increase in the interfacial protein concentration (Г) was obtained for MRPs. These results suggest that MR is useful in improving the utilization of this protein in food product development.

  • Evaluation of nutritional characteristics and bioactive compounds of
           soursop-yoghurt and soursop-frozen dessert
    • Abstract: Abstract The nutritional quality, sensory attributes, polyphenols and acetogenins content in yoghurt and frozen dessert formulated with soursop pulp were investigated. The addition of soursop pulp to yoghurt and frozen dessert improved the sensory attributes and the nutritional quality of soursop dairy products resulting in a composition of 0.92 and 2.17% of dietary fiber, 11.25 and 9.84 mg/100 g of vitamin C as well as 243.02 and 490.98 mg/100 g of total polyphenols, respectively. Acetogenins were extracted from both dairy products using maceration, sonication, microwave and Soxhlet. Sonication showed to be faster and safer than the other methods for acetogenins extraction. Higher annonacin (an acetogenin) content was found in yoghurt (38 ng/g) than in frozen dessert (15 ng/g). The quantification of bioactive compounds implied the nutraceutical properties to yoghurt and ice cream when they are added with soursop pulp. The results are useful for the consumers seeking healthier foods.

  • Effect of Salvia officinalis L. extract on chemical, microbial, sensory
           and shelf life of rainbow trout fillet
    • Abstract: Abstract The present study aimed at extending shelf life of rainbow trout fillet. Fish and seafoods are the most valuable nutrients, however, high levels of moisture, free amino acids, unsaturated fatty acids, and the content of nutrients make them to be categorized as spoilable and unstable foods. The objective of this research was to study of the shelf life of rainbow trout fillets using Salvia officinalis L. extract. Chemical and microbial analyses were performed on treatments. The usage of hydro-ethanol extract of S. officinalis L. significantly decreased microbial growth in fish fillet and there were significant differences among concentrations of the extract (p ≤ 0.05). The presence of extract of S. officinalis L. resulted in an inhibitory effect on the formation of TVB-N and FFA in comparison with the control group at all analytical times. In conclusion, the shelf life of fish fillets was increased noticeably using extract at 4 ± 1 °C.

  • Probiotic characterization of Lactobacillus brevis KU15153 showing
           antimicrobial and antioxidant effect isolated from kimchi
    • Abstract: Abstract Lactobacillus brevis KU15153 was isolated from kimchi and probiotic characterization was performed including analysis of its antimicrobial and antioxidant effects. Lactobacillus rhamnosus GG (LGG) was used as a probiotic control. L. brevis KU15153 survived under artificial gastric conditions and was non-hemolytic, showed antibiotic susceptibility, and did not produce carcinogenic β-glucuronidase. L. brevis KU15153 adhered strongly to HT-29 cells in the direct adherent assay and showed high cell surface hydrophobicity. Particularly, L. brevis KU15153 showed antimicrobial activity against the food-borne pathogens Escherichia coli ATCC 25922, Listeria monocytogenes ATCC 15313, Salmonella Typhimurium P99, and Staphylococcus aureus KCCM 11335. Antioxidant activity was assessed using the DPPH radical scavenging assay and β-carotene and linoleic acid inhibition assay. L. brevis KU15153 showed higher antioxidant activity than LGG. These results suggest that L. brevis KU15153 has potential for use as a probiotic organism.

  • Effects of hot air, microwave and vacuum drying on drying characteristics
           and in vitro bioaccessibility of medlar fruit leather (pestil)
    • Abstract: Abstract The effects of microwave (90 W and 180 W), hot air (60 and 70 °C) and vacuum (60 and 70 °C with 200 and 300 mbar) drying methods on drying characteristics, total phenolic content, antioxidant capacity, color and in vitro gastrointestinal digestion of medlar pestil were investigated. Medlar showed a good potential for pestil production while being the most applicable in microwave treatments. For drying kinetics, five thin-layer drying models were applied and the Page and Modified Page were the best fitted models. L*, b*, chroma and hue angle decreased while a* generally increased in dried pestils. Dried samples showed a general decrement in phenolics and antioxidant capacity. According to in vitro gastrointestinal digestion, intestinal phase of all the samples resulted with an increment in phenolics, FRAP and DPPH compared to undigested extracts. In conclusion, different drying methods may affect the release of phenolics and antioxidant capacity, while leading to increased bioaccessibility during intestinal digestion.

The dealcoholization of takju, in most cases, significantly (p < 0.05) reduced the total mineral (from 505.80 to 258.61 mg/L), free amino acid (from 989.81 to 293.58 mg/mL), antioxidant potentials and total phenolic (from 345.30 to 156.30 µg GAE/mL) contents remained in the control to RO-3 (takju sample obtained from 3-time reverse osmosis and heat treatment). Similarly, the content of volatile compounds was also significantly (p < 0.05) decreased with the dealcoholization treatments. The finding of this study clearly showed that dealcoholized takju could be prepared but at the expense of reduced nutritional and antioxidant potentials. This study could be an exemplary in promoting traditional beverages in different countries by producing low or alcohol-free drinks.

  • Antioxidant and antibacterial activities of a starch film with bioextracts
           microencapsulated from cactus fruits ( Opuntia oligacantha )
    • Abstract: Abstract The use of unconventional sources is very relevant in the food area. In the present study the development of active films with the addition of bioextract (BE) or microencapsulated bioextract (MBE) from xoconostle (Opuntia oligacantha) on chayotextle starch was investigated. The film formulations were: 4 g of chayotextle starch, 2 g of glycerol and 180 g of water, three films with BE added (0.4, 0.8 and 1.2 g) and three films with MBE added (0.4, 0.8 and 1.2 g). Total phenols, total flavonoids, antioxidant activity (ABTS and DPPH), Salmonella typhimurium inhibition, color and mechanical properties of the films were analyzed. The film with 1.2 g of MBE showed high concentration of total phenols (54.12 ± 0.77 mg EAG/100 g), total flavonoids (16.65 ± 0.10 mg QE/100 g) and antioxidant activity (29.11 ± 0.48 and 41.42 ± 1.81 mg EAA for ABTS and DPPH respectively). The addition of bioextract from xoconostle is an option for the development of active films with antioxidant properties.

  • Studies on the physicochemical characteristics of the New Zealand deer’s
           tail, Cervus elaphus var. scoticus (III)
    • Abstract: Abstract This study was designed to determine the nutritional profile and functional components of the NZT (New Zealand deer’s tail, Cervus elaphus var. scoticus Lönnberg). Twenty-nine fatty acids, eighteen amino acids, twenty-five minerals, chondroitin, and phospholipids were detected by the auto-fatty acid analyzer, auto-amino acid analyzer, inductively coupled plasma optical emission spectrophotometer, absorbance measurements, and by weighing after separating, respectively. 7-Ketocholesterol was isolated from alcohol extract by silica gel column chromatography analysis. Four steroid hormones (androstene-3,17-dione, β-estradiol, testosterone, and dehydroepiandrosterone), one base and seven nucleosides, and N-acetylneuraminic acid were detected by a HPLC-photodiode array and HPLC-fluorescence detector. As a result, NZT was composed of many nutritional and functional ingredients found in New Zealand deer’s antler (NZA) which was one of deer co-products, and it was considered that NZT could be a novel health food resource such as NZA.

  • Effects of ultrasonic treatment on the gel properties of microbial
           transglutaminase crosslinked soy, whey and soy–whey proteins
    • Abstract: Abstract This paper studied the influences of diverse ultrasonic power treatments on the physico-chemical properties of soy–whey mixed protein induced by microbial transglutaminase. Two groups of 15% (m/v) of protein solution-sole protein (as control group) and mixed protein were prepared and processed under different ultrasonic powers for 30 min. After ultrasonic power treatments, gel properties were significantly increased: under 300 W, the gel hardness of mixed protein reached a maximum of 998.9 g, with its water binding capacity scoring a maximum of 87%. According to the analysis of fluorescence emission spectrum, the fluorescence intensity and maximum absorption peak had changed, for different ultrasonic power treatments had exposed more groups. The Fourier Transform Infrared Spectroscopy also suggested that ultrasonic power treatments could change the secondary structure of gel samples. The scanning electron microscope demonstrated that the network structure of mixed protein gel displayed more regular and uniform after ultrasonic treatments.

  • Main parameters and the dynamics of volatile compounds during the
           fermentation of Chinese Mao - tofu from Huangshan region
    • Abstract: Abstract The physico-chemical parameters and kinetics of the volatile compounds during the fermentation of Chinese Mao-tofu was investigated. The levels of water soluble proteins, amino nitrogen and acidity increased gradually throughout the fermentation process, while that of reducing sugars peaked after 2 days before gradually declining. The protease activity increased significantly and reached the maximum levels at day 3, then it slightly decreased. The hardness and firmness decreased during the first 3 days, but both increased subsequently. The viscosity and adhesiveness was inversely related to the hardness and firmness. Forty-four volatile compounds were identified and quantified. Correlation analysis revealed significant correlation of the content of water soluble proteins and amino nitrogen with most volatile compounds. Acidity levels were positively correlated with that of ethyl caproate and hexyl alcohol, and negatively with 2-methyl butyric acid, palmitic acid, ethyl laurate, 1-octen-3-ol and 1-nonanol. Reducing sugar content was also positively correlated with ethyl caproate.

  • Effect of sucrose on rheological properties of xanthan gum-locust bean gum
           mixtures
    • Abstract: Abstract The effect of sucrose (0, 10, 20, 30, and 40%) on flow and dynamic rheological properties of xanthan gum (XG) mixed with locust bean gum (LBG) at different mixing ratios (100/0, 75/25, 50/50, and 0/100) were evaluated. The addition of sucrose significantly changed the flow behavior index (n), consistency index (K), storage modulus (G′), and loss modulus (G″) of XG, LBG, and XG-LBG mixtures. When XG and LBG were mixed, there was a synergistic effect on K and G′ values, and 50XG/50LBG mixture exhibited stronger synergy than 75XG/25LBG mixtures. However, the addition of sucrose reduced the magnitude of the synergistic effects, indicating that the presence of sucrose in XG-LBG mixtures negatively affected the synergistic interaction between gum molecules. Sucrose may competitively inhibit the binding of gum polymers to water molecules. The rheological properties of XG, LBG, and XG-LBG mixtures were affected by the addition of sucrose in a concentration-dependent manner.
