摘要:  研究了无花果蛋白酶对酵母蛋白的水解作用。结果表明,该酶水解酵母蛋白的最佳条件为:pHS.0.53℃,激活剂为半胱氨酸(0.02M—0.04M),用酶量与酵母蛋白用量之比为22743U:lg,反应时间为6h。在此条件下,酵母蛋白消化率可达91.79%

Abstract:  Hydrolysis of Yeast protein by ficin was investigated. The experiment results showed that the optimum condition of hydrolysis was: pH5. 0,:53℃, L-cys (0.02-0.04M), Ficin (u): yeast protein =22743: 1 (g), 6h. The protein digestion rate was 91.79% undcr the optimum condition.
