Monitoring Commercial Starter Culture Development in Presence of Red Grape Pomace Powder to Produce Polyphenol-Enriched Fresh Ovine Cheeses at Industrial Scale Level
نویسندگان
چکیده
Red grape Nero d’Avola cultivar pomace powder (GPP) was applied during fresh ovine cheese production in order to increase polyphenol content. Before cheeses were produced, the bacteria of a freeze-dried commercial starter culture isolated and tested vitro against GPP. Two dominant strains, both resistant GPP, identified. Thestarter inoculated pasteurized ewe’s milk curd divided into two bulks, one added with 1% (w/w) GPP another GPP-free. did not influence development, since lactic acid (LAB) counts 109 CFU/g at 30 d. To exclude interference indigenous LAB, analyzed, several colonies presumptive LAB isolated, purified typed. Four strains allotted Enterococcus Lacticaseibacillus genera. The direct comparison polymorphic profiles evidenced dominance over LAB. addition increased total phenolic compounds by 0.42 g GAE/kg. Sensory evaluation indicated that GPP-enriched well appreciated judges, providing evidence is suitable substrate availability content cheese.

Background and Objectives: Biscuit is the most popularly consumed bakery item, and due to higher consumption among children, increase of its nutritional value and safety is a necessity. Acrylamide is a potential carcinogen that is formed in carbohydrate-rich food products like biscuits at temperatures above 120oC. Among the various parameters, which affect acrylamide formation, the inhibitory e...

To shed further light onto the mechanisms of proteolysis that prevail throughout ripening of Portuguese cheeses, model cheeses were manufactured from bovine milk, following as much as possible traditional manufacture practices - using either animal or plant rennet. The individual role upon proteolysis of two (wild) strains of lactic acid bacteria - viz. Lactococcus lactis and Lactobacillus brev...

Effect of Grape Pomace Powder Addition on TBARS and Color of Cooked Pork Sausages during Storage
To determine the effects of grape skin and seed pomace (GSP) additions on the lipid oxidation susceptibility and the color change of cooked pork sausages, the chemical characteristics of GSP itself and the addition for two different levels of GSP (0.5 and 1.0% GSP, respectively) to sausages were examined. Both the redness and blueness of the GSP were significantly reduced as the pH level was in...

Prolonged and intensive exercise induces transient immunosuppression and is associated with an increased risk and severity of infections. The goal of this study was to characterize the antiviral and antibacterial properties of the bioactive metabolites of a blueberry-green tea-polyphenol soy protein complex (PSPC) in the serum of supplemented subjects during a 3-day intensified training period....
