Mycotoxins are secondary toxic metabolites that are produced by fungi representing threats to human and animal health. The objective of this study was to evaluate the adsorption capacity of Chitosan (CHI), and three cellulosic polymers (HPMC, CMC, and MCC), on six mycotoxins (AFB₁; FUB₁; OTA; T-2; DON; and, ZEA) using an in vitro digestive model for poultry. The adsorbent capacity of the materials in the supernatant of each compartment was evaluated by a non-competitive chemiluminescent assay. Control groups with no adsorbent material had an adsorption value of 0.00% against all six mycotoxins that were evaluated. All four materials tested showed significant ( < 0.05) binding activity against all of the mycotoxins when compared with the control non-treated group. However HPMC, CMC, and MCC showed better adsorbent capacity when compared with CHI.
霉菌毒素是由真菌产生的次生毒性代谢产物,对人类和动物健康构成威胁。本研究的目的是使用家禽体外消化模型,评估壳聚糖(CHI)和三种纤维素聚合物(羟丙基甲基纤维素、羧甲基纤维素和微晶纤维素)对六种霉菌毒素(黄曲霉毒素B₁;伏马毒素B₁;赭曲霉毒素A;T-2毒素;脱氧雪腐镰刀菌烯醇;以及玉米赤霉烯酮)的吸附能力。通过非竞争性化学发光测定法评估每个隔室上清液中材料的吸附能力。没有吸附材料的对照组对所有六种评估的霉菌毒素的吸附值为0.00%。与未处理的对照基团相比,所有四种测试材料对所有霉菌毒素均表现出显著(<0.05)的结合活性。然而,与壳聚糖相比,羟丙基甲基纤维素、羧甲基纤维素和微晶纤维素表现出更好的吸附能力。
