中文摘要:

      目的 探究碱性电解水对农产品中的黄曲霉毒素的消除作用。方法 用不同浓度的碱性电解水处理黄曲霉毒素样品, 去离子水处理样品作为对照品, 氮吹仪干燥, 样品衍生后采用进行高效液相色谱法检测, 确定碱性电解水对大米样品中黄曲霉毒素B1(aflatoxin B1, AFB1)的去除量。结果 高浓度的碱性电解水的AFB1去除率接近100%。电解水体积(V)与样品质量(m)的比值2:1(V:m)时, 去除效率接近90%, 且不引入二次污染物。细菌培养实验表明, 处理后的化合物不存在细胞毒性。不同处理组的色泽、味觉和其他感官指标均无显著差异(P>0.05), 在处理过程中没有明显的营养流失。结论 本方法快速简便、准确, 适用于消除农产品中的黄曲霉毒素。

英文摘要:

      Objective To explore the elimination effect of alkaline electrolytic water on aflatoxins in agricultural products. Methods Aflatoxin samples were treated with alkaline electrolytic water of different concentrations, and the samples were treated with deionized water as the control substance. The nitrogen blower was dried, and the sample was derivatized and subjected to high performance liquid chromatography to determine the removal of aflatoxin B1 (AFB1) from the alkaline electrolyzed water in the rice sample. Results The AFB1 removal rate of high concentration alkaline electrolyzed water was close to 100%. When the ratio of the volume of the electrolyzed water to the mass of the sample was 2:1 (mL:g), the removal efficiency was close to 90%, and secondary contaminants were not introduced. Bacterial culture experiments showed that the treated compound did not have cytotoxicity. There were no significant differences in color, taste and other sensory indexes between the different treatment groups (P>0.05). There was no obvious nutrient loss during the treatment(P>0.05). Conclusion The method is fast, simple and accurate, and is suitable for eliminating aflatoxins in agricultural products.
