Application of adsorbent agents technology in the removal of aflatoxin B1 and fumonisin B1 from malt extract

The commercially hydrated sodium calcium aluminosilicate (HSCAS) and the Egyptian montmorillonite (EM) had an excellent capability of adsorbing AFB1 and FB1 in an aqueous solution at different tested levels. The adsorption ratio of HSCAS ranged from 95.3% to 99.1% and 84.7% to 92.4% of the available AFB1 and FB1 respectively. EM showed an adsorption ratio ranged from 95.4% to 99.2% and 78.2% to 92.2% for AFB1 and FB1 respectively. Both adsorbents were effective at 0.5% level. Results of the ability of these adsorbents at level of 0.5% (w/v) to adsorb AFB1 and FB1 in malt extract spiked with 50, 100 and 200 ppb indicated that the capability of adsorbing of HSCAS ranged from 98.5% to 98.9% and 88.2% to 91.9% for AFB1 and FB1 respectively. Whereas, the capability of adsorbing of EM ranged from 98.1% to 98.7% and 88.2% to 92.5% for AFB1 and FB1 respectively.
