Abstract

A total of 70 tomato-based and 86 citrus-based products collected in China were analyzed for alternariol, alternariol monomethyl ether, tentoxin, and tenuazonic acid by ultraperformance liquid chromatography–electrospray ionization–tandem mass spectrometry. No toxins were found in any fresh tomato or citrus fruit samples. Tenuazonic acid was the predominant toxin detected in all tomato ketchup (10.2–1787 μg/kg) and tomato juice samples (7.4–278 μg/kg). Alternariol was quantitated at higher level than alternariol monomethyl ether with the ratio of alternariol/alternariol monomethyl ether ranging from 0.37 to 104 in 14 alternariol-positive tomato ketchup samples. Tentoxin was detected at much lower levels in all samples analyzed. Some citrus juice samples were positive for tenuazonic acid and alternariol monomethyl ether. It is necessary to conduct a systemic surveillance of Alternaria toxins in raw and processed foods to provide the scientific basis for risk assessment of dietary exposure to these toxins in Chinese populations.

摘要

在中国采集的 70 种番茄制品和 86 种柑橘制品，通过超高效液相色谱-电喷雾电离-串联质谱法分析了交链孢酚、交链孢酚单甲醚、棒曲霉素和脱氧雪腐镰刀菌烯醇的含量。新鲜番茄或柑橘类水果样品中均未检出毒素。所有番茄酱（10.2-1787μg/kg）和番茄汁样品（7.4-278μg/kg）中均检测到了主要毒素脱氧雪腐镰刀菌烯醇。在 14 个交链孢酚阳性番茄酱样品中，交链孢酚的定量水平高于交链孢酚单甲醚，交链孢酚/交链孢酚单甲醚的比值范围为 0.37-104。所有分析样品中棒曲霉素的检出水平均较低。部分柑橘汁样品中检出脱氧雪腐镰刀菌烯醇和交链孢酚单甲醚。有必要对生的和加工的食品中的交链孢霉毒素进行系统监测，为评估中国人群饮食暴露于这些毒素的风险提供科学依据。
