摘要:采用气熏蒸法对污染黄曲雰毒素ABI的花生进行处理,使其中的AFBI得到降解,并通过单因素实验考
察氮气浓度、氨熏温度、花生含水量和蒸熏时间等条件对降解率的影响,得到最优条件。结果表明,氨气熏蒸法最佳条
件为:气浓度10%,熏蒸温度40℃,花生含水量30%,氪熏时间96h,最高降解率为95.06%,降解效果显著。氨气
熏落法易于操作、成本低廉、降解卒高,且氮气来源广泛,适合大规模实际应用。

Abstract: Peanuts which contaminated by aflatoxin was Treated by ammonia gas method and AFBL was degraded
Effect of
concentration of ammonia gas, temperature, moisture of peanuts and time of degradation rate of AFBI
was investigated by single factor experiments, and the optimal condition was determined. The results show that the
optimum conditions for ammonia gas method were concentration of ammonia gas 10 %, temperature 40 C,
moisture of peanuts 30, ammonia smoked time 96 h, the highest degradation rate 95.06, the degradation
effect was remarkable. Ammonia gas method is easy to operate, low cost, high degradation rate, and the
ammonias source is rich, it is suitable for large-scale practical application
Key words: aflatoxins; degradation ammonia gas; peanut
