Suggested Applications:
Cheese analogues & Nutritional fortification.


Lactic Acid Casein

Intended Use

Casein, Acid Hydrolysate is a hydrochloric acid hydrolysate of casein for use in preparing microbiological culture media.

Product Summary and Explanation

Casein is a rich source of amino nitrogen. Treatment with hydrochloric acid hydrolyzes the protein into primarily free amino acids with some short peptide fragments. Tryptophan and vitamins present in the casein are destroyed by the acid hydrolysis. The salt content of this peptone is very high at approximately 36%.
While this peptone is used in a number of microbiological media formulations, its main usage is in Mueller
Hinton Agar.

Principles of the Procedure

Casein, Acid Hydrolysate is an acid hydroysate of casein. Casein, Acid Hydrolysate is an excellent source of free amino acids and short peptide fragments, which are required by microorganisms for growth.
