An alternative electrophoretic method that improves the separation, identification and relative quantification of bovine milk casein fractions and casein hydrolysates was developed. The method is based in the Tricine-SDS-PAGE technique while the relative quantification of milk proteins has been achieved by digital densitometry. The advantages of this procedure for milk proteins and milk protein...

The functionality of caseins in food systems depends on their solubility. The solubilities of whole casein, cr,l-casein, /3-casein, and dephosphorylated whole casein were measured as the pH was adjusted from 7 to 2 with HCl. When NaCl was added before pH adjustment, solubilities of whole casein at pH 2.5 decreased by 25, 40, 85, and 98% at NaCl concentrations of .01, .05, .1 and .2 M, respectiv...

PURPOSE Soy-based formulas are widely used as dairy substitutes to treat milk allergy patients. However, reactions to soy have been reported in a small proportion of patients with IgE-mediated milk allergies. The aim of this work was to explore whether P34, a mayor soybean allergen, is involved in this cross-reactivity. METHODS In vitro recognition of P34 was evaluated by immunoblotting, comp...

Phadungath, C. Casein micelle structure: a concise review Songklanakarin J. Sci. Technol., 2005, 27(1) : 201-212 Milk is a complex biological fluid with high amount of proteins, lipid and minerals. The function of milk is to supply nutrients such as essential amino acids required for the growth of the newborn. In addition, due to the importance of casein and casein micelles for the functional b...

In the present study, we investigated the effect of bovine colostrums on inhibition of DNA oxidative damage and low density lipoprotein (LDL) oxidation in vitro. Results showed that whey and skimmed milk exhibited not only higher inhibitory activities of oxidative damage of deoxyribose but also an inhibitory effect on the breakdown of supercoiled DNA into open circular DNA and linear DNA. The q...

Understanding the molecular properties and interactions of components within high-protein dairy powders is important in predicting rehydration performance. Raman spectroscopy was used to generate information which provided insights into between caseins micellar casein concentrate (MCC) powder formulated with varying proportions glycomacropeptide (GMP). The bands showed intense peaks at 1446 147...

Acidification of milk destabilizes casein micelles (CMs) and results in network formation. This process is fundamental during the manufacturing dairy gels such as cheese yoghurts. Understanding structural alterations CMs this aids to predict physicochemical sensory properties gels. Herein we utilize direct Stochastic Optical Reconstruction Microscopy (dSTORM) visualize individual hydrated chara...
