Overview

Description

In milk, casein exists as a calcium salt, forming micellar particles surrounded by soluble kappa-casein. The casein component of milk is relatively thermally stable and can withstand temperatures of 62-71°C, while the whey protein component denatures at this temperature. Casein is digested slowly in organisms and coagulates in the stomach, resulting in anti-catabolic properties of casein. Casein is a large, firm, dense curd that is extremely difficult to digest. There are four different types of casein, each with a different genetic variation. They are α-s1 casein, α-s2 casein, β-casein and κ-casein, respectively.
