Milk coagulation consists of four overlapping phases: enzymic hydrolysis, micelle aggregation, gelation and syneresis. The objectives of this study were to determine the effects of added CaCl2 on milk coagulation and the relationship between enzymic hydrolysis and micelle aggregation with substrate at different concentrations.
Addition of CaCl2 to milk is widely practiced in industry and in laboratories. This changes calcium concentration, pH and ionic strength. It is impossible to separate these three variables and investigate each one independently.
Addition of low levels of CaCl2 shortens coagulation time and increases curd firming rate. Low levels of CaCl2 …
