胰蛋白酶水解鲜猪皮的条件选择
Condition selection of the hydrolysis of pigskin with trypsin
摘要
Abstract
In this work, trypsin was used to hydrolyze pigskin in order to avoid the destruction of collagen polypeptide during acid-alkali hydrolysis process. It was found that the hydrolysis degree increased with the increase of the trypsin content. The maximum hydrolysis degree of pigskin was realized at pH 7~8, The initial rate of the hydrolysis reaction was large while it decreased after reacting for 30 minutes. The optimum condition of the hydrolysis of pigskin by trypsin was as follows: pH 7. 5, hydrolysis temperature 48 ℃, ratio of trypsin 40 mg/g, substrates concentration 8%, hydrolysis time 2 h. Under this condition, the hydrolysis degree of pigskin could reach 16%.关键词
