[Method] The average recovery rate was compared by comparing the relative standard deviation of extraction effects of primary water,anhydrous methanol and dichloromethane. [Result] When extracted with primary water,the relative standard deviation was 2.56% and the average recovery was 35.30%~51.12%. When extracted with anhydrous methanol,the relative standard deviation was 4.20%,and the average recovery was 81.32%~90.18%. When extracted with dichloromethane,the tissue status of the sample was abnormal,and the residue after nitrogen evaporation was oily,which could not be further determinated. [Conclusion] When extracted with anhydrous methanol. ELISA method had higher extraction accuracy and is more suitable for food determination., authors=WU Lan, HUANG Hua, DAI Xiaohong, FANG Juan, MA Houyang, WANG Dan, WU Jianxun, authorsList=WU Lan,

种不同提取剂在检测芝士粉中黄曲霉毒素M1含量方面的效果。[方法]通过对比一级水、无水甲醇、二氯甲烷3 种不同提取剂提取效果的相对标准偏差,比较平均回收率。[结果]用一级水提取时,相对标准偏差2.56%,平均回收率35.30%~51.12%;用无水甲醇提取时,相对标准偏差4.20%,平均回收率81.32%~90.18%;用二氯甲烷提取时,样品组织状态异常,氮流蒸发后残留物呈油状,无法进行后续检测。[结论]以无水甲醇作为提取剂时,ELISA法的提取准确性较高,更适用于食品检测领域。,

    [目的]本研究使用酶联免疫法(ELISA法)评估了一级水、无水甲醇、二氯甲烷3 种不同提取剂在检测芝士粉中黄曲霉毒素M1含量方面的效果。[方法]通过对比一级水、无水甲醇、二氯甲烷3 种不同提取剂提取效果的相对标准偏差,比较平均回收率。[结果]用一级水提取时,相对标准偏差2.56%,平均回收率35.30%~51.12%;用无水甲醇提取时,相对标准偏差4.20%,平均回收率81.32%~90.18%;用二氯甲烷提取时,样品组织状态异常,氮流蒸发后残留物呈油状,无法进行后续检测。[结论]以无水甲醇作为提取剂时,ELISA法的提取准确性较高,更适用于食品检测领域。

    [Objective] Enzyme-linked immunoassay(ELISA)was used to evaluate the effects of three different extractants of primary water,anhydrous methanol and dichloromethane on the determination of aflatoxin M1 in cheese powder. [Method] The average recovery rate was compared by comparing the relative standard deviation of extraction effects of primary water,anhydrous methanol and dichloromethane. [Result] When extracted with primary water,the relative standard deviation was 2.56% and the average recovery was 35.30%~51.12%. When extracted with anhydrous methanol,the relative standard deviation was 4.20%,and the average recovery was 81.32%~90.18%. When extracted with dichloromethane,the tissue status of the sample was abnormal,and the residue after nitrogen evaporation was oily,which could not be further determinated. [Conclusion] When extracted with anhydrous methanol. ELISA method had higher extraction accuracy and is more suitable for food determination.
