用pH 8~9的碱液处理花生原料时,花生油中黄曲霉毒素 B1可从10.4μg/kg 降低到4.5μg/kg ,效果明显,但工艺实现的难度较大。膨润土作为物理吸附剂用于脱除花生油中的黄曲霉毒素,当膨润土添加量为0.5%时,花生油中的黄曲霉毒素B1能够从12.5μg/kg降低至1μg/kg以内,同时可降低花生油的酸值,对过氧化值、风味无不良影响。物理吸附法通过搅拌、过滤工艺过程比较容易实现,在工业化生产中有良好的应用前景。

When peanut was treated by alkali solution of pH 8-9,the content of aflatoxin B1 of peanut oil could reduce from 10. 4 μg/kg to 4. 5 μg/kg,however,the treatment was difficult to carry out. Bentonite was used as physical adsorbent to remove aflatoxin from peanut oil,and the content of aflatoxin B1 reduced from 12. 5 μg/kg to below 1 μg/kg when 0. 5% of bentonite was added to peanut oil. Besides,the acid value of peanut oil reduced,and there was no negative effect on the peroxide value and the flavor of pea-nut oil. Physical adsorption could be easily achieved by methods of stirring and filtering,which had good application prospect in industrial production.
