ABSTRACT: This work presents a method for adding value to cheese whey residues by whey...

Functional RNAs, such as microRNA (miRNA) and mRNA, are present in milk, but their roles are unknown. To clarify the roles of milk RNAs, further studies using experimental animals such as rats are needed. However, it is unclear whether rat milk also contains functional RNAs and what their time dependent expression profiles are. Thus, we prepared total RNA from whey isolated from rat milk collec...

Two 21-day feeding trials were conducted using either 24 Hampshire (H) or 24 Chester White (CW) pigs at approximately 5 months of age to evaluate the effects of a diet containing 40% dried whey on the performance and the lactase activities in the gut of finishing pigs. Dried whey increased the incidence and severity of diarrhea in both CW and H (P<.005) but depressed the rate of gain, gain/feed...

Background and Objectives: Fast proteolysis of cheese in ripening process may lead to the premature attack of casein, release of the majority of enzymes into the whey, and loss of cheese composition from curd to whey. In this study, the effect of liposomal Flavourzyme on proteolysis of Iranian white brined cheese, as well as on the yield and composition of whey and curd was investigated. Mater...

TO THE EDITOR: Reitelseder et al. (4) are to be congratulated on their recent work. The use of intrinsically labeled proteins to study postexercise muscle protein accretion is a powerful tool, and the results are very interesting. I am concerned, however, by their interpretation that they have compared casein, as it exists in milk, to isolated whey when what they used was a not micellar casein ...

Epidemiological studies have suggested a relationship between diet and colon cancer incidence. Results from animal studies suggest that whey protein, but not casein protein, may provide protective effects against experimentally induced breast cancer in animals. In the current study, we investigated the effects of casein and whey diets on chemically induced colon cancer in male rats. Pregnant fe...

Utilization of milk whey still remains one of the most serious problems of the modern world dairy industry. Because of high biological value of whey it can be used as nutrient media in techniques of direct microbiological synthesis of complex high-molecular substances, for example the B12 vitamin, which participate in various biocatalytic reactions in organism providing normal functioning of th...

This work aimed at evaluating the influence of enzyme concentration, temperature, and reaction time in the lactose hydrolysis process in milk, cheese whey, and whey permeate, using two commercial β-galactosidases of microbial origins. We used Aspergillus oryzae (at temperatures of 10 and 55°C) and Kluyveromyces lactis (at temperatures of 10 and 37°C) β-galactosidases, both in 3, 6, and 9 U/mL c...

Milk was thermally processed by Ultra-High-Temperature (UHT, 132 to 154 C for 0 to 12 sec) and Vat (VAT, 66 C to 88 C for 0 to 30 min) systems. Representative milks were fermented into gels by a traditional yoghurt fermentation procedure. Selected functional properties, i.e. whey protein denaturation, gel strength, and their interrelationship were studied. Denaturation behavior of the five whey...
