Groups C, D, E and F had low pH values while group E exhibited the highest acidity level with its highest value (1.6% LA) at the 21st day. For the most part of storage period, group C had the highest levels of total solids while groups D, E and F had higher amounts of protein. Through storage duration, in all groups (except group B) the levels of ash, total solids and protein decreased.DNA based PCR is the most widely used technique for the detection of animal species in processed meat products. However, the detection of animal species in highly processed meat products, specifically, canned meat, has been reported to be challenging due to the presence of highly degraded DNA and/or the inability to extract sufficient amount of amplifiable DNA. The aim of this study was to evaluate the use of Real-time PCR to detect animal species in ready-to-eat meat products which represent highly processed complex food matrices. DNA was extracted from a total of 44 ready-to-eat meat products purchased from supermarkets in South Africa. The extracted DNA was screened for the presence of commonly reported undeclared animal species using Real-time PCR. https://www.selleckchem.com/ Real-time PCR successfully detected the animal species declared on the product label, thus demonstrating its suitability for highly processed complex food matrices. Undeclared animal species was detected in 27% of the meat products tested in this study. Surprisingly, four products marketed with a specific "no-pork" claim tested positive for pork. An additional eight products tested positive for undeclared chicken, beef and/or sheep. The presence of undeclared animal species indicates a need for food authenticity monitoring. In cases where it may not be practically feasible to prevent the adventitious presence of unintended animal species despite adhering to the highest standards of production, it may be advisable for manufacturers to implement precautionary labelling. The use of precautionary labelling for animal species in processed meat products is a new concept that requires further consideration.The objective of the present investigation was to identify and characterize the pigment produced by yeast strain Rhodotorula mucilaginosa (MTCC-1403) using food industry residues. Onion peel powder and Mung bean husks were explored as substrate for submerged fermentation at previously optimized conditions in 3-L bioreactor. The pigment extraction was followed by quantification and characterization in terms of UV-visible spectroscopy, Fourier transform infrared spectroscopy, high performance liquid chromatography and fluorescence spectroscopy. Anti-carcinogenic activity of extracted pigment was measured against MCF-7 breast cancer cells. Furthermore, the pigment was used for the development of confectionary products (hard boiled candy and jelly) at different concentrations to evaluate its influence on bioactive properties and functionality. UV-visible spectroscopic reports revealed that torularhodin, β-carotene, and torulene were major carotenoids present. In case of anti-carcinogenic activity, cell inhibition of 21.21% was observed with 40 μg of the extracted pigment after 72 h of incubation against MCF-7 cells. Significant influence of extracted pigment on confectionary products was observed for antioxidant activity, carotenoid content, color profile and sensory evaluation.The present study compared the effects of corn starch coatings incorporated with Zataria multiflora essential oil (ZEO) and cinnamaldehyde (CIN) in conventional, nanoemulsion (NZEO) and fortified nanoemulsion (NZEOC) forms, on specific spoilage microorganisms of chicken meat and on the fate of inoculated Listeria monocytogenes during 20 days storage at 4 ± 1 °C. Based on the results of GC-MS analysis of ZEO, carvacrol (36.62%) was the most important compound of essential oil. Samples coated with the starch solution containing nanoemulsions had better antimicrobial activities than conventional forms. Also, NZEOC treatment had the best antimicrobial properties at the end of storage with the following results Total viable count (7.96 log10 CFU/g), Psychrotrophic count (7.29 log10 CFU/g), Lactic acid bacteria (6.51 log10 CFU/g), Enterobacteriaceae count (6.98 log10 CFU/g), Mold and yeast count (5.16 log10 CFU/g) and inoculated L. monocytogenes (6.51 log10 CFU/g). Furthermore, the addition of CIN-ZEO during nanoemulsion formation (NZEOC) increased the antimicrobial properties of the samples compared to individual addition of NZEO and CIN (NZEO + CIN) to the starch solution. Therefore, corn starch coating containing NZEOC is recommended as a natural preservative to enhance the microbial stability of poultry meat.A simple, rapid and reliable extraction method for allulose content in jelly were optimized using response surface methodology. The extraction method was selected based on preliminary experiments, with a three-factor, three-level central complex design including 20 experimental runs to optimize the extraction parameters. The optimum extraction factors predicted were temperature of 66 °C, solvent of 74% (v/v) ethanol, and extraction time of 24 min under shaking water bath extraction. The measured parameters were in accordance with the predicted values. The developed analytical method was validated with regard to linearity, accuracy and precision presenting recovery level from 90.79 to 95.18% and detection limits varying from 0.53 to 1.62 mg/mL. Finally, the method will be potentially applicable to a commercial jelly food using optimum extraction.The aim of this study was to produce gluten free buckwheat noodles having high phenolics and minerals and to evaluate quality characteristics, scanning electron microscopy analysis, minerals, total phenolic content and phenolic compounds of the noodles. Corn starch or potato starch was used in the formulation of the noodle (40%, 50%, 60%). Starches improved cooking qualities of noodle. Improving effect of corn starch was more obvious compared to that of potato starch. Addition level of starches caused significant changes in color values (L*, a* and b*) of noodles. Buckwheat noodles have important minerals including potassium, phosphorous and magnesium. Total phenolic contents of noodles containing 40% starch were higher than that of other noodles. Major phenolic compounds of buckwheat noodles were caffeic acid, 4-hydroxybenzoic acid, catechin and rutin which have high antioxidant activity. As a consequence, these gluten-free products, which are suitable for celiac patients, had several healthy components.
