摘要


本研究目的為探討修飾黏土,蝦殼粉,蟹殼粉以及牡蠣殼粉不同吸附劑對黃麴毒素、伏馬鐮孢毒素、玉米赤黴烯酮毒素和嘔吐毒素之吸附效果。實驗系統所使用之毒素分成混合四種毒素以及四種單一毒素。觀察不同pH值,吸附劑顆粒大小,吸附劑CaCO3 去除率以及不同緩衝溶液系統對吸附效果之影響。在本研究中使用的吸附劑是由蝦殼粉經由處理後,所製備出來的吸附劑。其中吸附機制主要是由凡得瓦力去吸附黴菌毒素。吸附劑過篩後對毒素吸附效果影響不大。吸附劑CaCO3 去除率對玉米赤黴烯酮毒素吸附幾乎沒有影響。 在20 mL 0.015 M Citric –phosphate Buffer系統中的吸附效果比20 mL 0.03 M Citric –phosphate Buffer系統吸附效果高出許多,顯示鹽濃度對吸附效果具有顯著正向影響。黏土、Shr、Shr *和Shr M對黃麴毒素的吸附效果最好,幾乎可以高達100 % 吸附率。對伏馬鐮孢毒素最佳吸附效果可達80% 吸附率,而對玉米赤黴烯酮毒素最高吸附效果只有20% 吸附率,對嘔吐毒素最佳吸附效果也有高達100 %吸附率。 依本研究探討吸附劑對四種毒素吸附效果的結果資料未來可將吸附劑加入穀物飼料當中實際測試其吸附效果,進而改善人類飲食風險並且降低黴菌毒素經由食物鏈進入人體後造成的健康危害。

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.
