Mycotoxins have been known as one of the major food safety risks in food and feed. The focus of many studies is a quest for solutions that will provide decontamination of mycotoxin‐contaminated commodities. The aim of this research was to investigate the effect of ozone treatment on deoxynivalenol (DON), zearalenone (ZEN), and ochratoxin A (OTA) content in naturally contaminated ground corn. Moisture content in ground corn at the beginning of ozonation procedure was 10.00 ± 0.07%. Ozone levels of 40, 85, and 99 mg/L were applied on contaminated ground corn for 20, 45, 60, 90, 120, and 180 min, resulting in the decrease of DON, ZEN, and OTA up to 42.8%, 68.1%, and 70.3%, respectively. Unfortunately, DON, as a common contaminant of corn, appeared to be quite difficult to degrade, with estimated half‐life range of 217–330 min. First‐order kinetic model applied to mycotoxin degradation rate showed good fit for the application at ozone levels of 85 and 99 mg/L for all three mycotoxins, with a regression coefficient range from 0.82 to 0.97. Accordingly, ozone could be used as an effective way to decontaminate ground corn naturally contaminated with DON, ZEN, and OTA, although being more effective in the degradation of ZEN and OTA than in case of DON.

臭氧作为玉米粉的去污剂，含有脱氧雪腐烯酚，玉米赤霉烯酮和曲霉毒素A

霉菌毒素已被视为食品和饲料中的主要食品安全风险之一。许多研究的重点是寻求能够对霉菌毒素污染的商品进行消毒的解决方案。这项研究的目的是研究臭氧处理对自然污染的玉米地面中脱氧雪腐烯醇（DON），玉米赤霉烯酮（ZEN）和曲霉毒素A（OTA）含量的影响。在臭氧化过程开始时，玉米粉中的水分含量为10.00±0.07％。在受污染的玉米地面上施用40、85和99 mg / L的臭氧水平持续20、45、60、90、120和180分钟，导致DON，ZEN和OTA降低高达42.8％，68.1 ％和70.3％。不幸的是，作为玉米的常见污染物，DON似乎很难降解，估计半衰期为217-330分钟。应用于霉菌毒素降解速率的一级动力学模型显示，对于所有三种霉菌毒素，臭氧水平分别为85和99 mg / L时，应用非常合适，回归系数范围为0.82至0.97。因此，臭氧可以用作对天然被DON，ZEN和OTA污染的玉米地面进行污染的有效方法，尽管在ZO和OTA的降解方面比DON更有效。
