粮食储存用臭氧熏蒸对昆虫和害虫有用吗
与贮存粮食损失或由于生命体、虫害、啮齿动物和真菌和昆虫的实际形状而不是生物,如温度或湿度,它通向全球损失超过80万公吨的粮食库存。大多数时候，磷化铝被用于熏蒸，尽管它可能是危险的。此外，昆虫和害虫已经对磷酸盐产生了耐药性。其他熏蒸剂，如羰基硫化物、甲酸乙酯、氰化氢、甲基碘和丙烯氧化物，与磷酸盐相比成本较高(Singh和Sharma, 2015年)。另一方面，几项研究表明，臭氧在处理谷物方面是有效的，其优点是，如果适当控制剂量和暴露时间，它不会影响谷物的质量。
臭氧作为储存产品中昆虫和害虫的替代熏蒸剂
臭氧已被成功地用作储存产品的很好熏蒸替代品。已经进行了几项关于使用臭氧作为商业熏蒸剂的更环保替代品的研究。
下表总结了臭氧熏蒸对选定谷物和昆虫的浓度和暴露时间的影响。

臭氧作为真菌和真菌毒素的替代品
小麦可以用臭氧处理，以降低真菌和真菌毒素的水平。Guiseppe等人在2020年提交了一份表格，其中的研究表明，臭氧化是消除真菌毒素和为受污染的农产品解毒的有效方法。大约有400种真菌毒素，其中30种被认为对人类和动物有害。臭氧可以在许多食物/饲料和各种操作条件下降解最危险的真菌毒素。

臭氧已经为食品工业的主要问题带来了希望，如真菌毒素污染和农药残留物。O3的一个特别好处是它能够抑制真菌的生长、孢子和发芽，而不会失去营养或感官品质。必须确定食品和饲料的O3浓度、接触时间和其他处理条件，以确保加工的有效性和安全性。由于每一种O3应用都是独一无二的，上面显示的浓度和接触时间仅供参考。
