Abstrakt: | The paper studies the influence of technological conditions of alkaline-enzyme hydrolysis of chicken feathers on molecular weight of prepared keratin hydrolysates. Molecular weight (Mw) of hydrolysates was determined by SDS-PAGE and electrophoretic profiles of keratin hydrolysates were compared with electrophoretic profiles of protein standards, technical-grade gelatine and collagen hydrolysates. With the suitable choice of conditions during hydrolysis it is possible to prepare hydrolysates with prevailing portion of low-molecular weight fractions (Mw<20 kDa), medium-molecular weight fractions (Mw≈20-70 kDa) as well as high molecular weight fractions (Mw>70 kDa). | ||||||||||
