Abstract
A method for obtaining beta casein by separating it from para kappa casein involving the use of rennet casein is disclosed.
Claims13
A method for obtaining beta casein comprising the steps:
- of
- a) enzymatically curdling mammalian milk, to form a suspension or solution of rennet casein comprising para kappa casein and beta casein,
- b) cooling the thus produced suspension or solution of rennet casein,
- c) adjusting the pH to acid values, whereby said cooling and pH adjustment of said solution or suspension of rennet casein causes the formation of a solid and a liquid phase,
- d) separating said solid phase from said liquid phase, the former containing the para kappa casein and the latter containing the beta casein.

- a) enzymatically curdling mammalian milk, to form a suspension or solution of rennet casein comprising para kappa casein and beta casein,
- b) cooling the thus produced suspension or solution of rennet casein to a temperature of between -2.degree. C. and +10.degree. C.,
- c) adjusting the pH to a value of 4.00 to 5.00,
- d) separating the thus cooled and acidified suspension or solution of rennet casein into a solid phase and a liquid phase, the former containing the para kappa casein, the latter containing the beta casein.
