食用油中黄曲霉毒素降解技术的研究进展

Research Progress in Aflatoxin Degradation Technologies for Edible Oils

摘要:

黄曲霉毒素（aflatoxin，AF）是一类长期影响食用油安全的重要污染物，长期低剂量或短期大量摄入均会对人体健康产生危害。但目前仍无法完全去除食用油中的AF，因此，探究降低食用油中AF含量的方法具有重要意义。作者综述了食用油中AF的降解方法，主要包括高温处理、射线辐照、吸附脱毒等物理方法，氨气熏蒸、臭氧氧化等化学方法，以及微生物降解等生物方法，分析讨论了各种降解方法的原理、优点、不足及安全性，并对AF降解技术的发展趋势进行了展望。

Abstract:

Aflatoxin (AF), a notorious contaminant, has been a persistent challenge to the safety of edible oils. Prolonged exposure to low doses or acute consumption of high amounts of AF may induce serious health issues. Currently, no method can completely eliminate AF from edible oils. Therefore, it is crucial to explore strategies for reducing AF levels in edible oils. The measures to degrade AF from edible oils were reviewed, mainly including physical methods (such as high-temperature treatment, ray irradiation, and adsorption), chemical methods (such as ammonia fumigation and ozone oxidation), and biological methods (such as microbial degradation). In addition, this paper analyzed and discussed the principles, advantages, shortcomings, and safety of various degradation methods. Furthermore, it made an outlook on the development trend of AF degradation technology.
