Abstract: This paper focused on the impact factors of enzymatic hydrolysis by applying multivariate composite enzyme in the process. The results indicated that the quaternary multivariate composite enzyme, i.e.alkaline pectinase+tannase+hemicellulase+β-glycosidase, had the best degradation effect. The highest yield of diosgenin was 4.34%, when the condition was 1.5% compound enzyme of turmeric under 50℃, pH value 6.5, solid-liquid ratio of 1:4 and ethanol as extraction solvent for 10 h. Compared with the traditional acid hydrolysis which yield was only 1.61%,application of multivariate composite enzyme hydrolysis can improve the highest yield of diosgenin to 1.69 times.

Key words: yellow ginger, diosgenin, multivariate composite enzyme, enzymatic hydrolysis
