中文摘要：作为功能性食品的植物奶具有生理上的很多好处，且消费量日益上涨，但是人们对其污染方面的关注度很少，然而植物奶中很可能由于使用受污染的原料而含有残留物。因此，本文采用超高效液相色谱-串联质谱法对基于不同谷物、豆类、种子的功能性植物奶中最相关的镰刀菌毒素（伏马菌素B-1和B-2，HT-2和T-2毒素、玉米赤霉烯酮、脱氧雪腐镰刀菌烯醇和乙酰）残留进行检测，样本只采用简单的盐析辅助液液萃取进行处理。检测结果显示：定量限为3.2～57.7μg/L，回收率在80%以上，RSD小于12%。该方法还被应用于市售植物功能性饮料中的镰刀菌毒素检测，并在三种燕麦饮料中检测到了脱氧雪腐镰刀菌烯醇。
外文摘要：Vegetable milks are considered as functional foods due to their physiological benefits. Although the consumption of these products has significantly increased, they have received little attention in legislation with regard to contaminants. However, they may contain mycotoxins resulting from the use of contaminated raw materials. In this work, ultra-high-performance liquid chromatography tandem mass spectrometry has been proposed for the determination of the most relevant Fusarium toxins (fumonisin B-1 and B-2, HT-2 and T-2 toxins, zearalenone, deoxynivalenol and fusarenon-X) in different functional beverages based on cereals, legumes and seeds. Sample treatment consisted of a simple salting-out-assisted liquid-liquid extraction with no further clean-up. The method provided limits of quantification between 3.2 and 57.7 mu g L-1, recoveries above 80% and precision with RSD lower than 12%. The method was also applied for studying the occurrence of these mycotoxins in market samples of vegetable functional beverages and deoxynivalenol was found in three oat-based commercial drinks.
