Whey is a valuable co-product from cheese making that serves as a raw material for a wide range of products. Its rich nutritional content lends itself to rapid spoilage, thus it typically needs to be pasteurised and refrigerated promptly. Despite the extensive literature on milk spoilage bacteria, little is known about the spoilage bacteria of whey. The utility of carbon dioxide (CO2) to extend...

Patties were made from pork loin, individually vacuum- or aerobic-packaged and stored either at 4 or -40°C. Refrigerated patties were irradiated at 0, 1.5, 3.0 or 4.5 kGy absorbed dose, and frozen ones were irradiated at 0, 2.5, 5.0, or 7.5 kGy. Samples were analyzed for lipid oxidation, volatile production and odor characteristics. Refrigerated samples were analyzed at 0, 1 and 2 weeks, and fr...

In the present study, sunflower oil was used as extracting solvent for carotenoids and other lipophylic compounds from tomato by-products at 2.5% 5.0% (w/v) carotenoid-enriched oils were further in manufacturing of soy milk mayonnaise. An addition basil essential 0.05% (v/v) mayonnaise also investigated. Color parameters, pH, acid, peroxide values, well lipid oxidation measured by TBARS values ...

Background. Prebiotics are a category of nutritional compounds grouped together, not necessarily by structural similarities, but by ability to promote the growth of specific beneficial (probiotic) gut bacteria. Fructooligosaccharides (FOS) and inulin are among the most famous prebiotic compounds. In order to improve viability of probiotic bacteria during storage, fermented food should be supple...

Ricotta salata cheese is a salted variety of ricotta traditionally made in Sardinia (Italy) from the whey remaining after the production of Pecorino Romano protected designation of origin or other sheep milk cheeses. Ricotta salata cheese is very critical for the possible growth of pathogenic and spoilage microorganisms. Sporadic cases of listeriosis associated with ricotta salata cheese have b...

introduction: fish salting is a traditional method of processing in most countries including iran. there are different methods of salting which can be used for producing different salted products. there is variation in the amount of salt used in the salting process depending on the context of use.salting was done simultaneously with salt penetration into the muscles of fish and water dripping o...

The effects of hyperbaric storage (HS, 50–100 MPa) at room temperature (RT) on endogenous and inoculated pathogenic surrogate vegetative bacteria (Escherichia coli, Listeria innocua), Salmonella enterica bacterial spores (Bacillus subtilis) were assessed compared with conventional refrigeration atmospheric pressure for 60 days. Milk stored quickly surpassed the acceptable microbiological limit ...
