摘要
为明确西藏青稞中真菌毒素污染与分布,利用高效液相色谱-串联质谱仪对2021年和2022年采集的315份收获期青稞籽粒样品中30种真菌毒素含量进行了测定和比较分析。结果表明:315份收获期青稞籽粒样品中仅能检出7种镰刀菌毒素,其中最主要的是恩镰孢菌素B(enniatin B,ENNB),2021年和2022年检出率分别为22.7%、29.2%,其他镰刀菌毒素检出率均低于10%;2021年和2022年B区的青稞籽粒中ENNB平均含量分别为(99.1±63.3)、(312.8±79.1)μg/kg,均显著高于A区和C区;尽管不同地区青稞籽粒中ENNB含量与海拔高度呈负相关关系,但相关性不显著。
To investigate the contamination of mycotoxins in highland barley from Xizang,a total of 315 highland barley grain samples were collected from Xizang during 2021 and 2022.The samples were investigated for the occurrence of 30 mycotoxins using a high-performance liquid chromatography-tandem mass spectrometry method.The results indicated that only 7 Fusarium mycotoxins could be detected in 315 highland barley samples.The contamination rates of enniatin B(ENNB)were 22.7%and 29.2%,being the major mycotoxin among these detected mycotoxins during 2021 and 2022.However,the contamination rates of other mycotoxins were less than 10%during 2021 and 2022.In addition,the mean levels of ENNB were(99.1±63.3)μg/kg and(312.8±79.1)μg/kg in highland barley in B area during 2021 and 2022,being significantly higher than that in the A and C area.Moreover,the content of ENNB in highland barley was negatively correlated with altitude,but the correlation was not significant.
