【摘要】 超声波辅助番木瓜籽中硫代葡萄糖苷的降解试验中,在内源酶水解硫代葡萄糖苷的基础上进行超声波辅助。在单因素基础上,对超声时间、超声功率、超声温度3个因素进行优化。以异硫氰酸苄酯得率最高为优化目标,发现超声时间、超声功率、超声温度之间具有一定的交互效应。得到的最优超声时间16.17 min、超声功率60 W、超声温度38℃,异硫氰酸苄酯的得率为0.558%,此时硫代葡萄糖苷的酶解率为63.62%。更多还原

【Abstract】 Ultrasonic assisted degradation of glucosinolates in papaya seeds by ultrasound assisted with the hydrolysis of glucosinolates on the basis of endogenous enzymes. On the basis of single factor,three factors,ultrasonic time,ultrasonic power and ultrasonic temperature,were optimized. With the highest yield of benzyl isothiocyanate as the optimization target,it was found that ultrasonic time,ultrasonic power and ultrasonic temperature had some interaction effects. The optimum ultrasonic time was 16.17 min,ultrasonic power 60 W,ultrasonic temperature 38 ℃,and the yield of benzyl isothiocyanate was 0.558 %. At the same time,the enzymatic hydrolysis rate of glucosinolates was 63.62 %.更多还原
