Novel selective adsorbent for decontamination of Aflatoxin M1 from raw bovine milk

The aim of the study was to design a new absorbent for the removal of aflatoxin M1 as one of the contaminant and unhealthy factors in the milk. For this purpose, aflatoxin M1 adsorbent was coated on stainless steel plates using thermal co-polymerization method. Adsorption efficiency of designed adsorbent was evaluated in aqueous solution and raw bovine milk sample containing 500 ng / kg Aflatoxin M1 (10 times higher than maximum permitted level of aflatoxin M1 in bovine milk) using high performance liquid chromatography. The results showed that aflatoxin M1 absorption capacity in model solution and milk samples was respectively 93.32 and 90.31%, respectively. Also, the effect of the adsorption treatment on the chemical and physical properties of milk showed that the treatment had no significant effect on the nutritional and qualitative characteristics of raw milk (p <0.05).
