Objective: To optimize enzymatic technology of timosaponin AⅢ. Method: Taking bioconversion rate of timosaponin AⅢ as index
β-glycosidase enzyme was used to hydrolysis timosaponin
effect of reaction temperature
reaction time
pH and dosage of enzyme on enzymatic technology of timosaponin AⅢ was investigated by single factor test and orthogonal test. Result: Optimum enzymatic technology conditions were as follows:reaction temperature of 55℃
pH of acetic acid-sodium acetate buffer solution 5.0
dosage of enzyme 600 U· g-1
reaction time 3 h. Conclusion: Optimized enzymatic technology was simple and reliable with moderate reaction conditions
