酶法制取棉籽水解蛋白研究

STUDIES ON PREPARATION OF COTTONSEED PROTEIN HYDROLYZATE BY ENZYMATIC HYDROLYSIS

棉籽蛋白是一种优质植物蛋白，对棉籽蛋白采用酶法水解，能显著改善功能特性，研究得出：酶处理的最适参数范围为温度4O～45℃，时间5～7h，PH7～8，加酶量2～3％；棉籽水解蛋白DH为17～18时乳化性较好，DH为13～14时起泡能力较强．

Cttonseed Protein is one of the most important high-quality plant proteins in our country.ByEnzymatic hydrolysis,Its functional property can be remarkably improved. The research show that bestparameter ranger of enzymatic treatment are:added enzyme amount 2～3％,reaction time of enzyme 5～7h,pH7～8,temperature 40～45℃.
