以玉米须为原料,采用机械粉碎法将玉米须制备为5mm左右长短,采用热水浸提和乙醇沉淀的方法制备玉米须多糖.在此过程中,将玉米须多糖的提取率作为评价指标,采用单因素及正交试验方法优化提取条件,考察提取过程中浸提的温度、浸提的时间、料液比以及乙醇体积比对多糖提取率的影响.结果表明,当水浴温度为90℃、水浴时间为90min、料液比为1:25、乙醇体积比为3.5:1时,玉米须多糖的提取率最优为0.608%.随之研究了三氯乙酸溶液浓度对玉米须多糖除蛋白效果的影响,用单因素实验方法确定最佳工艺条件,将OD280值作为玉米须多糖除蛋白效果的评价指标,结果为,浓度为3%的三氯乙酸溶液对玉米须多糖除蛋白的效果最好,此时OD280为0.107.然后考察了玉米须多糖对大肠杆菌、芽孢杆菌、霉菌、酵母菌和白色葡萄球菌的抑菌作用,结果表明,玉米须多糖对大肠杆菌、白色葡萄球菌、芽孢杆菌的有较显著抑菌效果,对霉菌的抑菌效果一般,对酵母菌的抑菌效果不显著.

译文:Take the corn must as raw material, uses the machinery smashing law to have to prepare the corn is about 5mm the length, uses the hot water immersion to raise the method preparation corn which precipitates with the ethyl alcohol to have the polysaccharide.In this process, the corn must the polysaccharide extraction rate take the time, the material fluid which the appraisal target, uses the single factor and the orthogonal testing method optimization extraction condition, in the inspection extraction process soaks which proposes the temperature, soaks raises compares as well as the ethyl alcohol volume compares to the polysaccharide extraction rate influence.The result indicated, when the water bath temperature for 90℃, the water bath time is 90min, the material fluid compared to is 1:25, the ethyl alcohol volume compared to is 3.5:1, the corn must the polysaccharide extraction rate most be superior is 0.608%.Studied the trichloroacetic acid solution concentration along with it to have the polysaccharide to eliminate the protein effect to the corn the influence, with the single factor experimental technique determination best technological conditions, had the polysaccharide to eliminate the OD280 value as the corn the protein effect the appraisal target, the result is, the density was 3% trichloroacetic acid solution must the polysaccharide eliminate the protein to the corn the effect to be best, this time OD280 was 0.107.Then inspected the corn to have the polysaccharide to the backwoods coli, the bud spore bacillus, the mold, the saccharomycetes and staphylococcus albus's bacteriostasis function, finally indicated, the corn must the polysaccharide to the backwoods coli, the staphylococcus albus, the bud spore bacillus have the remarkable bacteriostasis effect, was ordinary to mold's bacteriostasis effect, was not remarkable to saccharomycetes' bacteriostasis effect.
