摘要
黄曲霉毒素及其他真菌毒素的降解技术一直是全球食品安全领域的研究热点。新型降解方式也在不断的探索中,主要有辐照、臭氧、电解水、低温等离子体、光催化以及生物降解法等,以期实现黄曲霉毒素的完全降解。本文中,笔者就近年来黄曲霉毒素的新型降解技术进行讨论,主要介绍各种新技术的降解机制、降解效率以及存在的优缺点等。其中,微波高功率以及在紫外800 MW/cm^2的强度处理下,可以实现黄曲霉毒素的完全降解;500 W高压灯光催化4 min可以达到99%以上的降解率;分枝杆菌菌株DSM 44556T反应4 h和8 h后的降解率接近100%。许多新技术在一定程度上可以100%降解黄曲霉毒素,对食品工业具有重要的研究意义。
The degradation of aflatoxin and other mycotoxin has been a research hotspot in the global food industry.New methods of degradation are also being explored in the hope of the complete degradation of aflatoxin.The degradation technologies of toxins mainly include irradiation,ozone,electrolytic water,cold plasma,photocatalytic degradation and biodegradation.In this paper,new degradation technologies of aflatoxin in recent years are discussed,and the degradation mechanism,degradation efficiency,advantages and disadvantages of the new technology are introduced.Traditional thermal techniques can cause the degradation of aflatoxins,but they are not enough to completely degrade aflatoxins in food.The new hot spot technology of electrolysis of water and cold ionomer has shown the possibility of complete degradation of aflatoxin.Therefore,the new degradation technology of aflatoxin has a great development prospect in the food industry.Microwave in high work rate and the intensity of UV 800 MW/cm^2 can completely degrade the aflatoxin.The 500 W high pressure lamp can be used for more than 99%degradation for four minutes.The Mycobacterium DMS 44556T can degrade the toxin completely in 4 h and 8 h.Many new technologies can completely degrade the aflatoxin,which is of great significance to food industry.
