Mycotoxins are well known secondary metabolites of various fungi. They pose a significant threat to human and animal when present in food or feed. They can be responsible for losses in grain production and in livestock or human intoxication. In this study, several mycotoxins were detected in Aspergillus fumigatus contaminated maize kernels. The contaminated kernels were treated with gaseous ozone at a concentration of 500 and 3000 ppm for 1 hour. Depending on the specific compound, the contamination level was reduced by up to 100%. This screening research showed that a concentration of ozone as high as 3000 ppm could be sufficient to completely remove several toxic compounds from the maize matrix.
真菌毒素是各种真菌产生的次级代谢产物，当存在于食物或饲料中时，会对人类和动物构成重大威胁。它们可能导致谷物减产以及牲畜或人类中毒。在这项研究中，从污染的黄曲霉玉米颗粒中检测到几种真菌毒素。污染的颗粒用浓度为 500 和 3000 ppm 的气态臭氧处理 1 小时。根据具体化合物的不同，污染水平降低了高达 100%。这项筛选研究表明，高达 3000 ppm 的臭氧浓度足以从玉米基质中完全去除几种有毒化合物。
