摘要
以Ｆ２５（Ａｓｐｅｒｇｉｌｕｓｎｉｇｅｒ）为出发菌株制备的生物制剂ＢＤＡ，在使用量为油样的５％～１０％时，能使花生油中的ＡＦＢ１由１００～２０μｇ／ｋｇ降至２２．３～１．９μｇ／ｋｇ。在放大试验中，ＢＤＡ能使花生油中的ＡＦＢ１含量从２０μｇ／ｋｇ降至５μｇ／ｋｇ以下，ＢＤＡ的最适解毒温度为４５～４８℃，解毒时间２小时。ＢＤＡ选择谷壳等为解毒酶和水份的共同载体，通过固体发酵方式制备，经解毒处理的花生油样保持浓郁的花生油香味，对其酸价、过氧化值、折光系数。
お new biological method has been developed for the detoxication of aflatoxin B 1 in peanut oil.BDA is a biological preparation produced by solid fermentation of Aspergillus niger F25.Experiments showed that 5% BDA was able to decrease the concentration of aflatoxin B 1 in peanut oil from 20～100 μg/kg to 22 3～1 9μg/kg at bench level and from 20μg/kg to below 5μg/kg in larger scale(i.e.100kg peanut oil).The optimal temperature and time for detoxication were 45～48℃ and 2h.Peanut oil treated in this way still kept its original sweet smell and no obvious changes were found in acid value,peroxide value,refractivity and water content.
