真菌毒素污染严重威胁食品、农产品和饲料产业高质量发展和人民生命健康。黄曲霉毒素B1是污染广，毒性最大的一种真菌毒素，具有强致癌性和致畸性。天然蒙脱石可通过离子-偶极子、羰基氧配位及静电引力等方式与黄曲霉毒素B1结合，因此有一定的吸附脱除作用。但天然蒙脱石在吸附黄曲霉毒素的同时可能会影响基质中的矿物质、维生素与其他营养组分，因此效果不太理想。通过不同的方式对天然蒙脱石进行改性，可以大幅度增强其吸附消减黄曲霉毒素B1的容量和选择性，本文主要综述了黄曲霉毒素B1的危害、蒙脱石吸附原理及其改性增强吸附消减性能的研究进展。

Mycotoxin contamination poses a severe threat to high-quality product development in the food, agriculture, and feed industries as well as serious risks to human life and health. Aflatoxin B1, which possesses strong carcinogenicity and teratogenicity, is one of most toxic and widespread mycotoxins. Natural montmorillonite can bind aflatoxin B1 through ion-dipole interactions, coordination of carbonyl oxygen and electrostatic attraction, thereby achieving the adsorptive removal of aflatoxin B1 to a certain extent. However, the removal effect of natural montmorillonite is unsatisfactory as minerals, vitamins, and other nutritional components in the matrix are affected during the adsorption process. The adsorption capacity and selectivity of natural montmorillonite for aflatoxin B1 can be considerably enhanced by different modification methods. In this paper, the hazards of aflatoxin B1, adsorption mechanisms of montmorillonite, and research progress in the modification of montmorillonite to enhance its performance in the adsorptive removal of aflatoxin B1 have been described.
