The composition and physical properties of raw milk from a commercial herd were studied over a 1 year period in order to understand how best to utilise milk for processing throughout the year. Protein and fat levels demonstrated seasonal trends, while minerals and many physical properties displayed considerable variations, which were apparently unrelated to season. However, rennet clotting time...

Safety of milk can decline because high concentrations steroid hormones like 17β-estradiol, which is associated with the development some oncological diseases and reproductive disorders. We studied effects thermal processing raw technologies production butter yogurt on concentration 17β-estradiol. For this purpose, we determined amount 17β-estradiol in milk, after pasteurization under different...

For preterm neonates, the quality of the first milk is crucial for intestinal maturation and resistance to necrotizing enterocolitis (NEC). Among other factors, milk quality is determined by the stage of lactation and processing. We hypothesized that unprocessed mature bovine milk (BM; raw bovine milk) would have less bioactivity than corresponding bovine colostrum (BC) in a preterm pig model, ...

Milk and yogurt are important elements of the human diet, due to their high nutritional value and their appealing sensory properties. During milk processing (homogenization, pasteurization) and further yogurt manufacture (fermentation) physicochemical changes occur that affect the flavor and texture of these products while the development of standardized processes contributes to the development...

Goat milk has been a rich source of proteins. The distinctive composition of goat milk, combined with its nutritional value, is linked to the liberation of protein fragments during digestion or technological processing, which are able to perform various biological activities. This has gain more attention due to its broad applications in the food, drug, and various other industries. Thus, here w...

Milk processing industries and distributors have problems with adulteration of liquid milk by the addition of bovine cheese whey. Recently, the detection of fraudulent manipulation of milk with whey has focused on the identification of glycomacropeptide (GMP). Current non-immunological methods to detect GMP in dairy products are expensive and time-consuming or have low sensitivity. In this stud...

The present study was conducted to investigate the existence of polymorphism at Kappa-casein (κ-CN) locus in the Nili-Ravi buffalo. A PCR-RFLP method was used to distinguish buffalo κ-CN alleles. The genotypes were confirmed through specific, clearly distinguishable DNA band pattern resulting from digestion with three selected restriction enzymes (HinfI, HaeIII and MaeII). Analysis of 163 anima...

Transgenic cows secreting over 3 microg of lysostaphin/ mL of milk are protected against mastitis caused by Staphylococcus aureus, but it is unknown if active lysostaphin persists through dairy processing procedures or affects the production of fermented dairy foods. The objective of this study was to determine the fate of lysostaphin as milk was pasteurized and then processed into cheese. Raw ...

Digestion of milkfat releases some long-chain (18-carbon) fatty acids (FAs) that can provide health benefits to the consumer, yet because they are found in small amounts and can be difficult to identify, there is limited information on the effects that common fluid milk processing may have on the digestibility of these FAs. This study provides FA profiles for raw and combinations of homogenized...
