Application of adsorbent agents technology in the removal of aflatoxin B(1) and fumonisin B(1) from malt extract.
The commercially hydrated sodium calcium aluminosilicate (HSCAS) and the Egyptian montmorillonite (EM) had an excellent capability of adsorbing AFB(1) and FB(1) 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 AFB(1) and FB(1) respectively. EM showed an adsorption ratio ranged from 95.4% to 99.2% and 78.2% to 92.2% for AFB(1) and FB(1) 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 AFB(1) and FB(1) 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 AFB(1) and FB(1) respectively. Whereas, the capability of adsorbing of EM ranged from 98.1% to 98.7% and 88.2% to 92.5% for AFB(1) and FB(1) respectively.
