Mycotoxins in food and feed are considered as an important safety issue of growing concern. One of the most important mycotoxins both from an economic as well as from a health point of view is deoxyniva-lenol (DON), a toxin produced by fungi of the genus Fusarium occurring mainly on grains. DON occurs in grain in concentrations up to 10.000 ug/kg. Costly invasive wet chemistry methods and sampling procedures for grain, which cannot be considered as representative, have to safeguard the consumer. Notseldom, however, the Tolerable Daily Intake (TDI) of 1 mu g/kg body weight as determined by the Joined Expert Committee of Food Additives (JECFA) is exceeded, which puts the population at risk. Recently a rapid acoustic technique with in-line capabilities has been tested for the quantitative determination of DON in wheat. It can be used to screen for DON in contaminated wheat at the point of harvest and with promising precision. Because it is fit for monitoring, this technique meets part of the problems previously associated with sampling and analysis.

机译：食品和饲料中的霉菌毒素被认为是日益关注的重要安全问题。来自经济以及健康观点的最重要的霉菌毒素之一是脱氧性葡萄球菌（Don），镰刀菌属的真菌产生的毒素主要发生在谷物上。唐在浓度的粒子中发生，浓度高达10.000 ug / kg。酿酒型湿湿化学方法和粮食的抽样程序，不能被视为代表，不得不保护消费者。然而，超过了由加入的食品添加剂（JECFA）确定的1μg/ kg体重的可容忍每日摄入量（TDI），这使得人口面临风险。最近，已经测试了一种快速声学技术，用于定量测定小麦的定量测定。它可用于在收获点和有前途的精确度下筛选污染的小麦。因为它适合监控，这种技术符合先前与采样和分析相关的部分问题。
