中文摘要：本文采用液相色谱与气相色谱-串联质谱联用技术对婴儿食用的谷物和谷类产品（N＝117）进行了研究已检测二十种不同霉菌毒素的自然存在。分析数据表明，67%的样本在不同水平上至少被一种霉菌毒素污染。其中脱氧雪腐镰刀菌烯醇存在率高达38%，且其在燕麦产品中的存在水平最高。另外，在25份样本中发现恩镰孢菌素 B，且其在燕麦产品中的存在水平也最高。此外，还有32%的阳性样本中至少存在两种霉菌毒素，且在阳性样本中发现多达六种不同的霉菌毒素组合。总体而言，婴儿食品中没有与毒性相关的霉菌毒素存在。
外文摘要：A study on a set of cereal and cereal-based products (n = 117) intended for infant consumption was performed to determine the natural presence of twenty different mycotoxins by both liquid chromatography and gas chromatography coupled to tandem mass spectrometry (MS/MS). Analytical data showed that 67% of analyzed samples were contaminated by at least one mycotoxin at variable levels. Deoxynivalenol presented the highest incidence (38%) and reached a maximum level of 240 ng/g in a bsissa sample (oat product), higher than the maximum level set for DON in cereal products (200 ng/g). While, enniatin B was found in 25 samples with a maximum level of 316 ng/g found also in a bsissa sample. Furthermore, 32% of positive samples showed co-occurrence of at least two mycotoxins, and a combination of up to six different mycotoxins was found within the positive samples. It was also observed that only the intake of bsissa and sorghum samples may pose a real OTA and HT-2 toxin health risk to the high consumers. Overall, no toxicological concern was associated to mycotoxins exposure for infant population; but a special attention should be paid to samples with co-occurring mycotoxins, where the estimated daily intake increase considerably for high consumers.
