【摘要】：采用酶解法對魔芋蛋白質(zhì)進行酶解,研究魔芋ACE抑制肽的制備工藝。以ACE抑制肽含量、多肽得率為指標,通過單因素試驗和正交試驗設計,優(yōu)化了堿性蛋白酶酶解魔芋蛋白制備ACE抑制肽的工藝。結果表明,堿性蛋白酶酶解魔芋蛋白制備ACE抑制肽的最佳工藝條件為:酶解pH 8.5、酶解溫度55℃、酶用量3 000 U/g、酶解時間210 min,在此條件下多肽得率為11.95%;ACE抑制肽含量為35.79 mg。
[Abstract]:The enzymatic hydrolysis of konjac protein was carried out to study the preparation process of Konjac ACE inhibitory peptide. Taking the content of ACE inhibitory peptide and the yield of polypeptide as the index, the single factor experiment and orthogonal design were adopted. The preparation of ACE inhibitory peptide by alkaline protease enzymatic hydrolysis of konjac protein was optimized. The results showed that the optimum conditions of alkaline protease hydrolysis of konjac protein to produce ACE inhibitory peptide were as follows: enzymatic hydrolysis of pH 8.5. The hydrolysis temperature was 55 鈩，
