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, different adhesives manufactured by using various casein powders (micellar casein, αS-, β- and ĸ-casein fractions, sodium caseinate calcium caseinate) were investigated for their properties potential application in the food industry. Casein-based sources of caseins produced differences adhesive strength determined. For isolation methods selective solubility, precipitation a decan...

A new fast and reliable reversed-phase high-performance liquid chromatographic method is proposed for quantifying all the major casein fractions during cheese proteolysis as an alternative to more complex methodologies. Excellent separation of caseins, para-κ-casein (ρ-κ-CN), αs1-casein (αs1-CN), αs1-I-casein (αs1-I-CN), αs2-casein (αs2-CN), β-casein (β-CN) was achieved, in terms linearity, rep...

Nentwich I . , Szépfalusi Zs. , Kunz C. , Spuergin P. , Urbanek R.: Antigenicity for Humans of Cow Milk Caseins, Casein Hydrolysate and Casein Hydrolysate Fractions. Acta Vet. Brno 2004, 73: 291-298. Cow milk casein consists of several fractions each of which have different structure and differing antigenicity. The aim of the study was to investigate the capacity of cow milk casein, casein frac...

Raw beans, c.v. Carioca 80, were fractionated into tegument (FR0), dialyzable solids (FR1), water-soluble (FR3) and salt-soluble (FR2, FR5) protein-rich fractions, and the insoluble residue (FR4). Each of these fractions was used at a level of 8% (w/w) in the preparation of balanced diets for rats with casein as the primary source of protein. The protein contributed by each fraction substituted...

This paper carried out a comparative analysis of different types of electrophoretic systems which were used for the analysis of casein complex from cow milk (polyacrylamide gel electrophoresis: for the neutral and acidic native conditions, in gradient variant, the presence of sodium dodecyl sulphate or with including urea). Taking into attention the separation efficiency, complexity of electrop...

To date, dozens of biologically active peptides formed during proteolysis of casein fractions have been discovered. The use of these peptides is closely related to the necessity of their rapid identification. The aim of this work was the development of an electrophoresis system for rapid identification of individual fractions in serial studies and the separation of the milk casein complex. Cons...

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....
