Abstract
Mycotoxins are a group of structurally diverse, naturally occurring chemical substances produced by fungi. The toxic effects of mycotoxins in humans and animals led to many scientific research for their detoxification from food and feed. Adsorbent materials such as charcoal, bentonite (Volclay) and Fuller's earth were studied for their efficacy of adsorbence to aflatoxins, fumonisin B1, deoxynivalenol (DON), ochratoxin, patulin, penicillic acid, T-2 toxin and zearalenone. The results showed that charcoal, at 1% concentration, had the highest adsorbence efficacy (close to 100%) to all the experimented toxins except penicillic acid and T-2 toxin. The bentonite (Volclay) at 1% concentration reduced the amounts of aflatoxins, fumonisin B1 and ochratoxin, while more than 50% of the other mycotoxins remained while more than 50% of the other mycctoxins remained in the solution. The Fuller's earth in aqueous solution had a weaker adsorbence affinity to mycotoxins compared to the dry Fuller's earth which adsorbed aflatoxins, fumonisin l31, DON and T-2 up to 68%, a well as more than 50% ochratoxin, patulin, penicillic shrimp toxicity test cnfirmed the experimental TLC data of the detoxification procedure of mycotoxins with adsorbents, charcoal, bentonite and Fuller's earth.
