摘要/Abstract

摘要： 本文以酵母葡聚糖为原料,选用环氧氯丙烷作交联剂,氯乙酸作羧甲基化试剂,在碱催化条件下合成了交联-羧甲基复合变性葡聚糖。以取代度为试验指标,通过单因素试验和正交试验确定了制备交联羧甲基葡聚糖(CCMG)的较佳条件为:反应温度50℃,反应时间5h,氯乙酸用量3.0g,NaOH浓度50%;在此条件下所得产品取代度为0.5左右。研究了交联羧甲基葡聚糖对真菌毒素玉米赤霉烯酮(ZEA)的吸附作用,结果表明,交联羧甲基葡聚糖对玉米赤霉烯酮具有较好的吸附效果,吸附量达到18.643μg/mgCCMG,高于酵母葡聚糖的吸附量2.296μg/mg。

Abstract: The crosslinking-carboxymethyl double modified glucan(CCMG)was prepared by the yeast glucan with the reaction of chloroacetic acid and epichlorohydrin in presence of alkaline. The optimal reaction conditions were determined by a single- factorial experiment and orthogonal experiment with the index of degree of substitution (DS). The results indicated that the optimum conditions are as follows: reaction temperature 50℃, reaction time 5h , chloroacetic acid 3.0g and NaOH 50%.The DS is about 0.5 under these conditions. Compared with β-D-glucan, CCMG showed a very good efficacy on the adsorption of ZEA. Its affinity to ZEA is up to 18.643μg/mg CCMG, which is greater than that of β-D-glucan with only 2.296μg/mg.
