Study on enzymatic hydrolysis process conditions of black bone chicken-blood
摘要
Abstract
Fresh black-bone chicken blood as the main raw material to study the enzymatic hydrolysis process conditions,the study showed that intermittent ultrasonic broken processing under the conditions had a better haemolytic effect than mechanical crushing.By comparing the hydrolysis ability of AS1.398 neutral protease, pepsin, papain, alkaline protease on black-bone chicken blood, AS1.398 neutral protease was selected for enzymatic hydrolysis; then on the basis of single factor and orthogonal experiments to determine the optimal enzymatic conditions for AS1.398 neutral protease were: the enzymolysis liquid initial pH7.5, enzyme dosage 8000U/g,the hydrolysis temperature 45℃, substrate concentration 8% , the enzyme solution time 6h. which the degree of hydrolysis reached 22.22%,hemoglobin content was 0.62 mg/mL.关键词
