Popis:	At the present time, for this purpose acid or enzymatic hydrolysis is performed of proteins (for example, casein, lactalbumin, cattle blood) followed by purification and the elimination of the (I) from the hydrolysate [6, 7]. As a rule, acid hydrolysates of proteins are colored because of the presence of humic substances and products of the decomposition of amino acids (pH 0.1-0.3). Consequently, necessary stages of the industrial process for obtaining preparations of a protein hydrolysate are its demineralization and decoloration. For these purposes wide use is made of EAE-10P ion-exchange resin [8, 9], the hydrolysate is neutralized with milk of lime [i0, ii], or the hydrochloric acid is distilled off in vacuo and the residue is neutralized with a saturated solution of alkali [12].
