糧食儲存用臭氧熏蒸對昆蟲和害蟲有用嗎
與貯存糧食損失或由于生命體、蟲害、嚙齒動物和真菌和昆蟲的實際形狀而不是生物,如溫度或濕度,它通向全球損失超過80萬公噸的糧食庫存。大多數時候，磷化鋁被用于熏蒸，盡管它可能是危險的。此外，昆蟲和害蟲已經對磷酸鹽產生了耐藥性。其他熏蒸劑，如羰基硫化物、甲酸乙酯、氰化氫、甲基碘和丙烯氧化物，與磷酸鹽相比成本較高(Singh和Sharma, 2015年)。另一方面，幾項研究表明，臭氧在處理谷物方面是有效的，其優(yōu)點是，如果適當控制劑量和暴露時間，它不會影響谷物的質量。
臭氧作為儲存產品中昆蟲和害蟲的替代熏蒸劑
臭氧已被成功地用作儲存產品的很好熏蒸替代品。已經進行了幾項關于使用臭氧作為商業(yè)熏蒸劑的更環(huán)保替代品的研究。
下表總結了臭氧熏蒸對選定谷物和昆蟲的濃度和暴露時間的影響。

臭氧作為真菌和真菌毒素的替代品
小麥可以用臭氧處理，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為受污染的農產品解毒的有效方法。大約有400種真菌毒素，其中30種被認為對人類和動物有害。臭氧可以在許多食物/飼料和各種操作條件下降解很危險的真菌毒素。

臭氧已經為食品工業(yè)的主要問題帶來了希望，如真菌毒素污染和農藥殘留物。O3的一個特別好處是它能夠抑制真菌的生長、孢子和發(fā)芽，而不會失去營養(yǎng)或感官品質。必須確定食品和飼料的O3濃度、接觸時間和其他處理條件，以確保加工的有效性和安全性。由于每一種O3應用都是獨一無二的，上面顯示的濃度和接觸時間僅供參考。
