碩士 / 朝陽科技大學 / 應用化學系碩士班 / 98 / This study was designed to explore the modification of clay, shrimp powder, crab shell powder and oyster shell powder of different adsorbents on aflatoxin, fumonisins toxin , zearalenone toxin and deoxynivalenol toxin adsorption. Experimental system used four kinds of toxins and toxin mixture into the four single toxin. Effects of different pH, adsorbent particle size, binder CaCO3 removal and the different buffer systems on the effect of adsorption. In this study, the use of binder powder from shrimp shell by the treatment, out of the binder prepared. Adsorption mechanism which is mainly van der Waals forces to the adsorption of mycotoxins. Binder adsorption sieved little effect on the toxin. CaCO3 removal of the toxin zearalenone little effect on adsorption.
In 20 mL 0.015 M Citric-phosphate Buffer System adsorption ratio of 20 mL 0.03 M Citric-phosphate Buffer system, much higher adsorption, indicating a significant effect of salt concentration on the adsorption of positive influence. Clay, Shr, Shr * and Shr M on the adsorption of aflatoxin best, almost 100% absorption rate. fumonisins toxins adsorption efficiency up to 80% absorption rate, while the zearalenone toxin adsorption of only 20% of the maximum adsorption rate, adsorption on the vomiting toxin has the best 100% absorption rate.
Of this research binder adsorption effect on the results of the four toxins future information can be added adsorbent grain feed them to test its adsorption, and thus improve the human diet and reduce the risk of mycotoxin entering the human body through the food chain causing health hazards.
