摘要

動物飼料中，普遍在都會使用黴菌毒素吸附劑，來減低毒素對於動物的不良影響，因為黴菌毒素吸附劑使用上方便，而且價格便宜。市面上已經有許多種類的黴菌毒素吸附劑，飼料中的毒素，通常會產生一種以上的黴菌毒素，因此黴菌毒素吸附劑，有利於降低飼料中黴菌毒素。
研究目的主要為探討黴菌毒素吸附劑，比較在單一與混合不同黴菌毒素的吸附率，本實驗採用的黴菌毒素為，黃麴毒素(aflatoxin， AFL )、伏馬鐮胞菌毒素(fumonisin，FUM )、玉米赤黴烯酮(zearalenone， ZEA )。吸附劑採用 Calibrin-Z 。單一毒素實驗中，吸附劑對於AFL與FUM毒素皆有90%以上的平均吸附率，ZEA平均吸附率為47%；混合AFL與FUM後維持平均90%的吸附率，吸附劑對於ZEA的平均吸附率由47%降為27.5%。另外，實驗過程中避免磁石恆溫攪拌，因為吸附劑易沾黏於磁石上，造成吸附率下降。

Mycotoxin adsorbent that selectively binds specific mycotoxin is widely used in animal feeds to reduce the potential health hazards. Due to frequent occurrences of mycotoxins, the use of mycotoxin adsorbents has becoming popular. On the market, many types of mycotoxin adsorbents are available. Usually, there is more than one kind of mycotoxins presented in the feeds. Therefore, selection and understanding mycotoxin adsorbents are very important for an efficient removal of mycotoxin(s). The main purpose of this research is to investigate and compare the binding behaviors of mycotoxin adsorbent in single and mixed toxin systems. A popular adsorbent was used as the adsorbent. In the experiment of single toxin system, adsorbent adsorption rate is higher than 90 percent for the AFL and FUM toxin and 50 percent for ZEA, in single toxin systems. The binding rate remained above 90 percent in AFL - FUM mixing system. In AFL-FUM- ZEA mixing system, the ZEA binding rate dropped to 25 percent. However, such observation about ZEA was not consistent in a series of experiment, indicating there may be other factors involved in binding behavior in mixed toxin systems.
