摘要

Mycotoxins, which are toxic secondary metabolites produced by fungi, contaminate a wide range of food and feed items and represent significant health concerns to both humans and animals. The most potent and widespread of these are aflatoxins (AFs), particularly Aflatoxin B1 (AFB1), which is commonly found in peanuts, cottonseed, spices, animal feed, and milk. AFB1 is linked to liver cancer, immunosuppression, reproductive problems, and growth retardation, particularly in poultry, cattle, and humans. Aflatoxin (AF) resistance to conventional detoxification treatments is frequently caused by its chemical stability and persistence - necessitating the development of more sustainable and efficient approaches. This review, which focuses on adsorption-based detoxification of AFs, looks at a variety of mitigation options, including chemical, biological, and physical procedures. Bentonite clay is unique among binders due to its high adsorption capacity, low cost, and regulatory approval from institutions such as the European Food Safety Authority (EFSA) and the European Commission (EC Regulation 1060/2013). Recent advances in bentonite clay surface modification have increased the efficacy of AF binding and enhanced the physicochemical properties of clay, which reduces the bioavailability of AFs in animal feed. The review discusses bentonite's structural features, adsorption methods, kinetic behavior, potential developments and its future prospects.
