Abstract
The amount of [beta]+K-casein in whole casein was estimated in a buffered solution of acid casein in the presence of Ca, by means of the difference in optical densities (400 m[mu]) at 0[degree] and 35[degree]C; the concentration of [alpha]s-casein was obtained by difference. The method is simple, convenient and suitable for routine determinations. Analysis of skimmilk indicated that [beta]-casein accounted for 19-36%, K-casein for 10-23%, and [alpha]s-casein for 49-60% of the total casein.This publication has 11 references indexed in Scilit:
