Seed processing technologies are essential for seed safety and functionality through protection of physicochemical quality, pathogen inactivation, aflatoxin detoxification and alleviation of mutagenicity. Design of a pilot‐scale unit of pulsed electric fields (PEF) to treat sesame seeds with respect to quality parameters, Aspergillus parasiticus inactivation and aflatoxin reduction as well as alleviation of aflatoxin mutagenicity were prompted in this study. PEF energy ranged from 0.97 to 17.28 J achieved maximum reductions of peroxide value and acidity number of 67.4 and 85.7%, respectively, and did not change color L*, a*, b* and hue values. A 60% reduction of A. parasiticus counts occurred at the maximum PEF energy. Aflatoxins G1, G2, B1, and B2 contents decreased by 94.7, 92.7, 86.9, and 98.7%, respectively. Except for the samples treated by 2.16 J with 100 μg/plate and by 6.80 J with 10 μg/plate, PEF treatment provided elimination of aflatoxin mutagenity. It is concluded that PEF treatment can be used to treat sesame seeds with preservation of physicochemical properties, inactivation of A. parasiticus and decomposition of aflatoxins with reduced mutagenicity.

脉冲电场控制寄生曲霉，黄曲霉毒素和致突变性水平的潜力：芝麻种子质量
种子加工技术通过保护物化质量，病原体灭活，黄曲霉毒素解毒和减轻诱变性，对于种子安全和功能至关重要。在这项研究中，有人提出了设计用于处理芝麻的中试脉冲单位（PEF）的质量参数，寄生曲霉灭活和黄曲霉毒素减少以及减轻黄曲霉毒素诱变性的设计。PEF能量在0.97至17.28 J范围内，分别实现了最大过氧化物值降低和酸度值分别降低67.4和85.7％，并且不改变颜色L *，a *，b *和色相值。寄生寄生曲霉减少60％计数发生在最大PEF能量下。黄曲霉毒素G1，G2，B1和B2的含量分别下降了94.7、92.7、86.9和98.7％。除了用2.16 J 100μg/板和6.80 J 10μg/板处理外，PEF处理消除了黄曲霉毒素的致突变性。结论是，PEF处理可用于处理芝麻，其物理化学特性得以保留，寄生曲霉失活，黄曲霉毒素的分解具有降低的致突变性。
