| Abstract | ||||
| Malt extract is widely used in beverages, food and pharmacautical industries. The use 01 mycotoxin-contaminated barely In the production of malt resulted in the contamination with mycotoxins and frequently the presence of mycotoxlns in the final product. The aim of the present work was twofold: (1) testing ofl'No adsorbent agents including commercially hydrated sodium calcium aluminositicate (HSCAS) and an Egyptian montmorillonite (EM) to adsorb aflatoxin B, (AFB1) and fumonlsin B, (FB,) in aqueous solutlon, and (2) the application 01 these adsorbent agents in the removal of AF8, and FB, from malt extract. In one experiment, four level of each sorbent e.g. 0.5, 1, 2 and 4% (w/v) and three level of each mycotoxlns e.g 5, 10 and 50 ppm were tested. Results revealed that the adsorbent agents had an excellent capability of adsorbing AFB, and FB, 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, and FB, respectively in aqueous solutions. EM showed an adsorption ratio ranged from 95.4 to 99.2 and 78.2 to 92.2% for AFB, and FB, respecUvely. Both adsorbent agents were effective at 0.5% level in the adsorption of AFB, and FBIIA second experiment was conducted to evaluate the ability of these adsorbent agents at level of 0.5% (w/v) to adsorb AFB, and FBt in malt extract spiked with 50, 100 and 200 ppb. Our results Indicated thaI the capability of adsorbing of HSCAS ranged from 98.5 to 98.9 and 88.2 to 91.9% for AFB, and FB, respectively. Whereas, the capability of adsorbing of EM ranged from 98.1 to 98.7 and 88.2 to 92.5% for AFB, and FB, respectively. These data concluded that sorbent technology is effective in the removal of AFB, or FBI in malt extract used In beverages and other industries, and importantly, EM is as effective as HSCAS at a dose as low as 0.5"10 (wlv). | ||||
