General description

Casein is produced from skim milk. It is roughly made of 80% bovine milk protein and has only 10 to 20% essential amino acids per gram of protein.

Application

Casein from bovine milk is a phosphoprotein. There are four main types of Casein which make up approximately 80% of the total protein in bovine milk: α-s1 Casein, α-s2 Casein, β-Casein, and κ-Casein. Casein is proposed to be the main protective constituent in milk.

Biochem/physiol Actions

Partial gastrointestinal digestion of casein is a rich source of bioactive peptides, such as β-casomorphin. However, bovine casein is not homogeneous; variants A1 and B do lead to production of β-casomorphin 7 production, while A2 does not.
Casein is considered as a slow digesting protein as it digests at a slower rate than other proteins. It also has an anti-catabolic effect.

Preparation Note

Lactic acid precipitated New Zealand casein extracted with ethyl alcohol.

Analysis Note

Tested for vitamin content.

      Note that product C3400 is considered to be essentially vitamin-free. The purification of this material includes an ethanol extraction process that strips the oil soluble vitamins. However, the product is not tested for the presence of any residual vitamin content. Please see the links below to review this product.
