Milk Ultracentrifugal Opalescent Layer. 3. Yield and Casein and …
Abstract The yield and composition of opalescent layer, pellet and supernatant fractions from skim milk (0 to 5C) were investigated as a function of ultracentrifugation time from 1 to 8h at 147,000 × g. Casein micelles in opalescent layer after 1 and 8h accounted for 42 and 1% of total skim milk casein, respectively. The casein content of opalescent layer casein micelles decreased from …
