ABSTRACT:

Manuscript describes producing keratin hydrolysate from sheep wool through two-stage technology whose principle consists in first having wool processed in an alkaline environment during the first stage, and then effecting hydrolysis in the second stage through the action of proteolytic enzyme. Experiments were planned in accordance with factor schemes of 23 types in which factors under study were influence of first stage hydrolysis duration (6-24 hours), duration of hydrolysis second stage (6-24 hours) and quantity of added proteolytic enzyme (1-5 %) on quantity of decomposed wool.

KEYWORDS:
