Bovine milk has been shown to contain bioactive components with bone-protective properties. Earlier studies on bovine milk whey protein showed that it suppressed bone resorption in the female ovariectomised rat. A new osteotropic component was subsequently identified in the whey basic protein fraction, but bone bioactivity may also be associated with other whey fractions. In the present study, ...
In the present study, the in vitro scavenging activity of sheep whey protein against free radicals, as well as its reducing power were determined and compared with that of beef protein, soy protein and cow whey protein. Moreover, the possible protective effects of sheep whey protein from tert-butyl hydroperoxide (tBHP)-induced oxidative stress in muscle C2C12 cells were determined by assessing ...
Recent advances in processing research and membrane technology have allowed for the fractionation of whey proteins directly from milk. The differences in attributes between whey proteins isolated from milk and those isolated from cheese whey are becoming an important factor for dairy protein processors considering this new avenue for fractionating whey proteins. The symposium will cover membran...
Some animals thrive more satisfactorily on a milk that contains whey and curd protein. For this reason human milk protein (which contains about 40% whey) may have some advantages over cows' milk protein (which contains about 15% whey) and so infants feeding formulae based on demineralised whey in which the protein has been modified to achieve a curd:whey ratio similar to that in human milk may ...
Heat treatment of milk aims to inhibit the growth of microbes, extend the shelf-life of products and improve the quality of the products. Heat treatment also leads to denaturation of whey protein and the formation of whey protein-casein polymer, which has negative effects on milk product. Hence the milk heat treatment conditions should be controlled in milk processing. In this study, the denatu...
Whey is a by-product obtained during coagulation of milk by using acid and/or rennet or physico-chemical process for the preparation of cheese, paneer, chhana, chakka and casein. Whey contains about 80-90% of the volume of milk that is used for production these products. It contains about half of the milk solids in which nutritional components such as lactose, protein and minerals are present i...
Whey protein ingestion has been shown to effectively stimulate postprandial muscle protein accretion in older adults. However, the impact of the amount of whey protein ingested on protein digestion and absorption kinetics, whole body protein balance, and postprandial muscle protein accretion remains to be established. We aimed to fill this gap by including 33 healthy, older men (73 ± 2 yr) who ...
Introduction: Limited studies have been conducted on the effect of whey protein during endurance training on fat mass, plasma lipoprotein and hormonal changes in obese people. The aim of this study was to investigate the effects of endurance training combined with whey protein supplementation on serum Leptin, Testosterone to Cortisol ratio, Lipid profile and body composition in obese male stude...
The effects of the addition of whey protein concentrates and clarification by-products obtained from ovine cheese whey and deproteinized whey (Sorelho) on the yield and quality of the whey cheese (Requeijão) have been evaluated. Whey protein concentrates were obtained by ultrafiltration of skimmed whey and Sorelho. The clarification by-products were obtained after the treatment of the skimmed w...
Whey powder, due to its lactose and protein contents, can be used as an important flour improver to decrease the rate of staling. In the present investigation, whey powder was added at 5 levels (zero to 5%, W/W) to the flour of Sangak bread. Bread was baked according to the formula and procedure used by traditional Sangak bakeries. Bread samples were kept at room temperature or under refrigerat...
