摘要

Abstract > A strong trend toward using highly selective mass spectrometry technologies for screening of multiple mycotoxins has been observed in recent years. In the present study, the process of validation of a multimycotoxin screening method based on liquid chromatography–high‐resolution mass spectrometry method is presented. The method was intended for the simultaneous screening of the major Fusarium toxins (deoxynivalenol, 3‐ and 15‐acetyl deoxynivalenol, T‐2 and HT‐2 toxins, zearalenone, enniatins A, A1, B, and B1, and beauvericin) in wheat. The sample preparation protocol was based on a double extraction (methanol followed by acetonitrile/water mixture) and purification through solid‐phase extraction C18 column. To provide insights for full exploitation of the potential of the double‐stage high‐resolution mass spectrometry detection, a full‐scan acquisition event followed by a sequence of 5 fragmentation events (variable data‐independent acquisition) was set for mycotoxin detection, the latter to be exploited for confirmatory purposes. Method analytical performances were evaluated through in‐house validation and small‐scale interlaboratory study, designed according to Commission Regulation 519/2014/EU, setting performance requirements for screening methods for mycotoxins. Screening target concentrations were close to European Union maximum permitted or indicative levels. The in‐house validation provided the precision of the response under repeatability conditions and the intermediate precision (both resulting lower than 30%), the cutoff value, and the rate of false suspect results for negative (free of the mycotoxin of interest) samples, which resulted lower than 0.1% in all cases. The collaborative study provided reproducibility and laboratory independent cutoff values.

高分辨率质谱法的多霉素筛选方法的验证方法。该方法旨在同时筛选主要的镰刀菌毒素（脱氧萘酚，3-和15-乙酰脱氧脱氧酚，T-2和HT-2毒素，酸甲酮，烯胺A，A1，B和小麦的B1和Beauvericin）。样品制备方案基于双萃取（甲醇，然后是乙腈/水混合物），并通过固相萃取C18柱纯化。为了提供完全利用双阶段高分辨率质谱检测的潜力的见解，为霉菌毒素检测设置了5个碎片事件（可变数据无关采集）的全扫描采集事件，后者是用于霉菌毒素检测被剥削以获得确认目的。方法通过内部验证和小规模的间接研究评估分析性能，根据佣金规则519/20100 /欧盟设计，确定用于霉菌毒素的筛选方法的性能要求。筛选目标浓度接近欧盟最大允许或指示水平。内部验证提供了可重复性条件下的响应的精度，中间精度（均导致低于30％），截止值和误操病结果的否定嫌疑结果为消极的（不含感兴趣的霉菌毒素）样本，在所有情况下，导致低于0.1％。协作研究提供了可重复性和实验室独立截止值。裁减分析 </span> <span class="z_kbtn z_kbtnclass
