Many health risks associated with Aflatoxin M1 (AFM1) drive the demand for its control. Adsorption studies of AFM1 were performed using activated charcoal (AC) and imarsil (0.5, 1 or 2%) at aflatoxin contamination rates of 9, 231 or 456 ng/L for 5 h at 4, 16, 28 and 32oC. The aflatoxinadsorbing capabilities of the two adsorbents depend on the adsorbent, adsorbent concentration, contact time and treatment temperature. At 4, 16 and 28oC, Imarsil demonstrated significant reductions (p<0.05) at the highest contamination rate and adsorbent concentration; while at 32oC, significant reductions (p<0.05) were observed at all contamination rates and adsorbent concentrations. However, at all treatment temperatures AC exhibited a very poor adsorbent capacity, except at 32oC where a mild activity was only exhibited at the highest contamination rates and adsorbent concentration. Results from the present study indicate that imarsil demonstrates a potential for aflatoxin reduction in the developing tropical world.
