Proteose-peptone content in the milk of Italian Friesian cows with moderate and high somatic cell values

Abstract

Milk with elevated somatic cell count has an impaired quality and reduced value, especially for the manufacture of cheese (Schaellibaum, 2002). If the milk has a high cell count, the deterioration during syneresis with a longer clotting time and weak curd leads to an increased moisture content and a lower dry matter yield (Politis and Ng-Kwai-Hang, 1988; Urech et al., 1999; Cooney et al., 2000). Most of proteose-peptones (PP) and γ-caseins of the milk result from the enzymatic hydrolysis of the native casein (Pâquet, 1989; Bastian and Brown, 1996)......
