中文摘要:

      链格孢菌是多种重要农作物的病原体, 可产生70余种链格孢毒素, 不仅造成农作物减产和品质下降, 也会存在于食品加工制品中, 对人类和动物造成安全威胁。链格孢毒素可污染粮食、水果和蔬菜等农作物, 在番茄及其产品、小麦和果干等食品中的含量较高, 尤其以细交链孢菌酮酸的含量最高。脱除链格孢毒素的方法主要包括物理法、化学法和微生物法, 通过降解、吸附毒素或者抑制真菌产毒以降低农作物或食品中链格孢毒素的含量。本文总结了农作物和食品中链格孢毒素污染现状及其脱毒方法, 旨在为降低链格孢菌毒素对农作物的危害, 提高食品安全提供参考。

英文摘要:

      Alternaria is a pathogen of many important crops and can produce more than 70 kinds of Alternaria toxins, which not only cause yield loss and quality deterioration of crops, but also exist in processed food products, posing a safety threat to humans and animals. Alternaria toxins can contaminate crops such as grains, fruits and vegetables, and are present in high levels in foods such as tomatoes and their products, wheat and dried fruits, especially in tenuazonic acid. The methods of Alternaria toxins removal mainly include physical, chemical and microbiological methods to reduce the content of Alternaria toxins in crops or foods by degradation, adsorption of toxin or inhibition of fungal toxicity. This review summarized the contaminated status of Alternaria toxin in crops and food and the detoxification method of that, in order to provide a reference for reducing the harm of Alternaria toxin to crops and improving the food safety.
