黄曲霉毒素是由黄曲霉和寄生曲霉产生的一组具有致癌、致畸、致突变作用的次级代谢产物。黄曲霉毒素可在多种农产品中发现，特别是在谷物、油籽、玉米和花生中。本研究对臭氧氧化花生脱毒的条件进行了优化。花生中黄曲霉毒素在含水量为5%（w/w）时对臭氧敏感，在室温下与6.0mg/L臭氧反应30 min后，黄曲霉毒素易于降解。总黄曲霉毒素和黄曲霉毒素B-1（AF B（1））的脱毒率分别为65.8%和65.9%。本研究还对花生样品的品质进行了评价。结果表明，处理后的样品中多酚类物质、白藜芦醇、酸价和过氧化值与未处理的样品相比，差异均不显著（P > 0.05）。结果表明，臭氧氧化法是一种很有前途的花生黄曲霉毒素脱毒方法。(C)2013爱思唯尔有限公司保留所有权利。
Aflatoxins are a group of secondary metabolites produced by Aspergillus flavus and Aspergillus parasiticus with carcinogenicity, teratogenicity, and mutagenicity. Aflatoxins may be found in a wide range of agri-products, especially in grains, oilseeds, corns, and peanuts. In this study, the conditions for detoxifying peanuts by ozonation were optimised. Aflatoxins in peanuts at moisture content of 5% (w/w) were sensitive to ozone and easily degraded when reacted with 6.0 mg/l of ozone for 30 min at room temperature. The detoxification rates of the total aflatoxins and aflatoxin B-1 (AFB(1)) were 65.8% and 65.9%, respectively. The quality of peanut samples was also evaluated in this research. No significant differences (P > 0.05) were found in the polyphenols, resveratrol, acid value (AV), and peroxide value (PV) between treated and untreated samples. The results suggested that ozonation was a promising method for aflatoxin detoxification in peanuts. (C) 2013 Elsevier Ltd. All rights reserved.
