the purpose of this study is to produce an oil-in-water nano-emulsion by ultrasonication. casein combined with inulin used as continuous phase, while dispersed phase consisted of fish oil. the size of the nano-emulsion and the ph of nano-emulsion were characterized. ultrasound has been used for preparing emulsion by 24 khz intensity for 120 seconds. prepared nano-emulsion was investigated by pa...

this study investigated the effect of season (wet and dry) on milk composition of the dromedary camel (camelus dromedarius). milk samples representing the wet and dry seasons were analyzed for total solids (ts), fat (f), solids-non-fat (snf), ash, crude protein (cp), nitrogen soluble at ph 4.6 (sn), mineral content (mc) and casein fraction (cnf). camel milk had higher (p<0.05) fat content in th...

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....

Protein profile, in vitro gastrointestinal digestion and antioxidant potential of two fresh cheese samples obtained by kombucha inoculum traditional starter culture have been investigated this study. There is a significant difference protein profile bioactive between samples. Kombucha contains higher proportion protein, predominantly the casein fractions (α-casein β-casein) compared to culture....

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...

Adult male rabbits were fed on semi-purified diets containing soya-bean protein isolate, casein or formaldehyde-treated casein as the protein source and 1 g cholesterol and 5 g of the non-absorbable marker chronic oxide/kg diet. The concentration of cholesterol in serum and in liver was increased on both the casein and formaldehyde-treated-casein diets. Excretion of bile acids and their concent...

VÍTKOVÁ M., RAUCH P., FUKAL L. (2002): Optimisation of indirect competitive ELISAs of α-, β-, and κ-caseins for the recognition of thermal and proteolytic treatment of milk and milk products. Czech J. Food Sci., 20: 53–62. Polyclonal antibodies were raised against six immunogens (three native and three thermally treated casein fractions: α+β-casein, κ-casein and whole casein). Using these antib...
