Casein Peptone is a pancreatic digest of casein. Pancreatic digestion produces a balanced mixture of amino acids, including essential amino acids, in optimal ratio and low molecular weight peptides. In many cases, this makes for a more nutritious hydrolysate, especially for those organisms that prefer peptides to amino acids.
