High-fat-high-cholesterol diets containing casein or a Vicia faba bean (faba bean) protein concentrate as the protein source were given to rats for 5 weeks. When the faba bean protein concentrate or its ethanol extract was present in the diet, a marked decrease was found in the level of circulating cholesterol associated with the lower-density lipoproteins (very-low-, intermediate- and low-dens...

In the present study, the effect of feed Se supplementation on the Se content of raw milk and mozzarella cheese as well as the effect on cheese quality and functionality were determined. The Se milk was produced by supplying dairy cow feed with Se yeast (0.3mg of Se/kg of dry matter), resulting in a Se concentration in milk of 35.81μg/L. The fat, casein, and whey protein of Se milk were separat...

A non-protein diet supplemented with vitamins fed to a bile fistula dog caused marked reduction in cholic acid and taurocholic acid formation. A mixture of pure amino acids, essential for growth, promoted taurocholic acid production for a limited period. A mixture of amino acids composed of 2 fractions of a casein digest fortified with dl-methionine and dl-tryptophane, (Merck Vuj-N-ix), also re...

In this study, we describe the characterization of microbial Transglutaminase -modified casein using a combination of immunological and proteomic techniques. Using 5-(biotinamido)pentylamine as an acyl acceptor probe, three Q residues of β-casein and one of αs1-casein were found to participate as acyl donors. However, no Q-residues were involved in network formation with κ-casein or αs2-casein....

In this study, we report differences in the observed gliding speed of microtubules dependent on the choice of bovine casein used as a surface passivator. We observed differences in both speed and support of microtubules in each of the assays. Whole casein, comprised of α(s1), α(s2), β, and κ casein, supported motility and averaged speeds of 966±7 nm/s. Alpha casein can be purchased as a combina...

To characterize the hypercholesterolaemic effect of casein further, four groups of young male rabbits in two separate experiments were placed on cholesterol-free semi-purified diets for 12 weeks. The diets were similar in composition, with either casein or soya-bean-protein isolate providing the protein source (250 g/kg). In two of these diets the salt mix was reduced by 45% (normally 40 g/kg) ...

Abstract Casein as the major protein of milk is a promising source for biopolymer fibers. Current casein-based fibers are fabricated by dissolving caseins in alkaline media and wet spinning coagulation bath containing harsh chemicals. In milk, casein present so-called micelles (CMs). Based on rennet-induced aggregation, we developed process that can be applied micellar sustainable way without u...

This study was conducted to assess the variations of milk coagulation properties (MCP) among two native cattle types, e.g., Thamankaduwa White (TW), Lankan (LC) and improved breeds, Friesian (FR) Jersey (JS), in relation distinctive protein compositions. MCP traits, including rennet time (RCT), curd firmness, meltability yield, were measured. The profile each breed/type analyzed using capillary...
