摘要：
探讨粉碎时间、提取剂、掩蔽剂质量分数等因素对酶联免疫吸附分析（enzyme-linked immunosorbentassay，ELISA）法检测玉米赤霉烯酮的影响。结果表明，玉米样品粉碎时间180 s以上、70%甲醇溶液为提取剂、添加0.025%鱼皮胶的磷酸盐缓冲液为掩蔽剂时，检测结果最为稳定。本实验结果对高稳定性玉米赤霉烯酮检测ELISA试剂盒的开发具有参考价值。

Abstract:
In the present study, the effects of grinding time, extraction solvents and different amounts of masking agents on the detection of zearalenone were explored. The most stable results were obtained when corn samples were ground for more than 180 s, and then extracted with 70% methanol using phosphate buffer solution with 0.025% fish skin gelatin as the masking agent. The findings of this study can provide a reference for the development of highly stable ELISA kit for the detection of zearalenone in corn.
Key words: mycotoxin, zearalenone, enzyme-linked immunosorbent assay, quantitative detection
