Abstract Deoxynivalenol (DON), a worldwide cereal contaminant, is mainly produced by Fusarium spp.. It not only affects the cereal quality reducing the end-use, but also poses a serious threat to food and feed safety. In order to protect human and animal health and reduce economic losses, it is important to find ways to reduce DON and mycological contamination. This study aimed to evaluate the effect of acid electrolyzed water (AcidEW) and alkaline electrolyzed water (AlkEW) with different pH values on eliminating DON and inactivating fungi in naturally contaminated wheat grains. Both AcidEW and AlkEW showed great activity on the elimination of DON and mycological contamination. The optimal pH values of AcidEW and AlkEW for DON elimination were 5.5 and 9.5, respectively. Afterwards, effects of pH 5.5 AcidEW and pH 9.5 AlkEW on F. graminearum and qualities of wheat grains were observed. AcidEW and AlkEW displayed better activity on reducing F. graminearum than pure water. Both AcidEW and AlkEW had no effect on the moisture, crude protein, wet gluten, whiteness and microstructure of wheat grains, as compared with the pure water. Moreover, AcidEW could improve farinograph property of wheat grains. Therefore, either AcidEW or AlkEW can be as a novel method to reduce DON and fungal contaminations, especially, AcidEW.

用酸碱电解水降低小麦籽粒脱氧雪腐镰刀菌烯醇和真菌污染

摘要 脱氧雪腐镰刀菌烯醇（DON）是一种世界性的谷物污染物，主要由镰刀菌产生。它不仅影响谷物质量，减少最终用途，而且对食品和饲料安全构成严重威胁。为了保护人类和动物健康，减少经济损失，找到减少呕吐毒素和真菌污染的方法很重要。本研究旨在评估不同pH值的酸性电解水（AcidEW）和碱性电解水（AlkEW）对天然污染小麦籽粒中DON的去除和真菌的灭活效果。AcidEW 和 AlkEW 在消除 DON 和真菌污染方面表现出极大的活性。AcidEW 和 AlkEW 消除 DON 的最佳 pH 值分别为 5.5 和 9.5。然后，pH 5.5 AcidEW 和 pH 9.5 AlkEW 对 F 的影响。观察禾本科和小麦籽粒的品质。与纯水相比，AcidEW 和 AlkEW 在减少禾谷镰刀菌方面表现出更好的活性。与纯水相比，AcidEW 和AlkEW 对小麦籽粒的水分、粗蛋白、湿面筋、白度和微观结构均无影响。此外，AcidEW 可以改善小麦籽粒的粉质分析性能。因此，无论是 AcidEW 还是 AlkEW，都可以作为减少 DON 和真菌污染，尤其是 AcidEW 的新方法。
