中文摘要：大麦(Hordeum vulgare L.)是一种重要的粮食作物，也是啤酒生产的主要原料之一。鉴于大麦及大麦制品的重要性，评估其安全性，就必需懂得关于大麦生产中霉菌毒素污染的知识。本研究用LC-MS/MS法测定了啤酒大麦脱氧雪腐镰刀菌烯醇（DON）及玉米赤霉烯酮（ZEN）的水平。结果显示，所分析样品的DON及ZEN水平很高，分别达94和73.6%。DON和ZEN共现于大多数大麦粒样品中，霉菌毒素含量高于巴西和欧盟设定的最大限值。
外文摘要：Barley (Hordeum vulgare L.) is an important cereal crop for food and represents one of the main ingredients in beer production. Considering the importance of barley and its derived products, the knowledge about the mycotoxin contamination in the barley production is essential in order to assess its safety. In this study, the levels of deoxynivalenol (DON) and zearalenone (ZEN) in brewing barley were determined using a LC-MS/MS method. A survey was conducted in 2015 to estimate the mycotoxin levels in these products (n = 76) from four crop regions in Brazil. The results showed high levels of DON and ZEN in the analyzed samples, with contamination levels of 94 and 73.6%, respectively. The mean levels of DON and ZEN ranged from 1700 to 7500 μg/kg and from 300 to 630 μg/kg, respectively. Barley samples from regions 1 and 2 presented higher levels of ZEN and DON, respectively, and those from region 4 presented lower levels of both. Co-occurrence of DON and ZEN was seen in the majority of the barley grain samples, and the mycotoxin content was above the maximum levels established by the Brazilian and European regulations.
