Study on the the Methods of Mycotoxins Elimination from Food and Feeds

Article excerpt

Background: The worldwide contamination of foods and feeds by mycotoxins is a significant problem.often more than one mycotoxin is found in a contaminated substrate.To con- trol the toxins, correct agricultural operations,chemical and biological control and elimination of them(use of chemical compounds and different adsorbents)are effective.in this paper the function of different adsorbents has been studied.

Methods: The adsorbents mixed with feeds(aluminosilicates, active charcoal and some polymer compounds)were as- sayed.adsorption of aflatoxin B1 by natural montmorillonite and montmorillonite modified by Cu+2 ions in PH=3,7,9,adsorption of zearalenone by cholestyramine and other adsorbents and adsorption of sterigmatocystine in con- centrations of 5,10,50 µgr/ml by montmorillonite in concen- trations of 2,1,0.5,4mg/l were studied.

Results: In assaying adsorbents of feed mycotox- ins,aluminosilicates were the best. Adsorption of aflatoxin B1 by montmorillonite was high(more than%93).between the adsorbents of zearelenone,cholestyramine had the highest power of adsorption. …
