中文摘要:

      目的 验证玉米赤霉烯酮胶体金试纸条对玉米基质、小麦基质样品中玉米赤霉烯酮检测的准确性。方法 根据试纸条说明书方法, 将不同浓度系列的玉米基体和小麦基体质控样品进行前处理后, 用试纸条测定其浓度。结果 检测样品为玉米基体时试纸条间无显著性差异, 相对准确率为99.5%, 检测结果准确; 小麦基体时, 试纸条显著性差异为39.03(自由度df=1), 相对准确率为80.5%, 检测结果差异较大。结论 该方法基本可行, 适合对玉米中玉米赤霉烯酮的含量进行定性检测, 不适合对小麦中玉米赤霉烯酮含量进行定性检测。

英文摘要:

      Objective To verify the accuracy of detection of zearalenone in corn matrix and wheat matrix samples by zearalenone colloidal gold test strip. Methods According to the test strip specification method, the corn substrate and the wheat substrate quality control samples of different concentration series were pretreated, and the concentration was determined by test strips. Results There was no significant difference between the test strips when the samples were tested on the corn matrix, the relative accuracy was 99.5%, so the test results were accurate. When the samples were tested on the wheat matrix, the significant difference of the test strip was 39.03 (degree of freedom df=1), the relative accuracy was 80.5%. The test results were quite different. Conclusion The method is suitable for qualitative detection of zearalenone content in corn, but not suitable for qualitative detection of zearalenone content in wheat.
