摘  要：
为优化酒醅对河豚毒素的降解条件,本实验以酒厂发酵24 d的酒醅为降解材料,考察降解温度、降解时间、摇床转速三个因素对河豚毒素降解效果的影响,并在确定的最优条件下,用小鼠生物法去评价酒醅对河豚毒素的降解效果。实验结果表明:当酒醅添加量为16 g,温度为30℃,摇床转速为50 r/min的条件下,酒醅降解能力最强;在上述最优条件下,随着TTX降解时间的延长,昆明鼠的死亡时间延长,5 d后保持不变。

摘  要：
In order to optimize degradation conditions of fermented grains on tetrodotoxin(TTX), 24-days fermented grains were used as degradable material, the influence of degradation conditions was investigated, such as dosage of fermented grains, degradation temperature, degradation time, and shaking speed. The mouse bioassay was used to evaluate the degradation effect of the fermented grains under the optimal conditions. It was found that when the fermented grains was 16 g, the temperature was 30 ℃, and the rotate speed was 50 r/min, the fermented grains had the best degradation ability; the death time of Kunming mice was prolonged with the extension of TTX degradation time under the optimal conditions, and then remained unchanged after five days.
