马铃薯氧化淀粉胶粘剂制备研究

摘要

[ Objective ] The aim was to identify the oxidized potato starch adhesive preparation of the most appropriate oxidant. [ Method ] Potato starch was used as raw material, potassium permanganate, hydrogen peroxide, sodium hypochlorite as oxidant, the first oxidation of potato starch was conducted, and oxidized potato starch adhesive was prepared. Preparation of different oxidants and oxidation of potato starch carbonyl content,carboxyl content determination, oxidation of potato starch adhesive viscosity, water loss rate, initial viscosity, mobility, storage and other properties of the test were determined. [ Result] Under the same conditions, prepared by hydrogen peroxide in various adhesive properties of potato starch weve significantly better than the other oxidants preparation of the adhesive. [ Conclusion] Preparation of potato starch oxidation of hydrogen peroxide was the most suitable oxidant adhesive.%[目的]研究制备马铃薯氧化淀粉胶粘剂最合适的氧化剂.[方法]选用马铃薯淀粉为原料,以高锰酸钾、双氧水、次氯酸钠为氧化剂,先对马铃薯淀粉进行氧化,然后制备马铃薯氧化淀粉胶粘剂.对不同氧化剂制备的马铃薯氧化淀粉的羰基含量、羧基含量进行测定,并对马铃薯氧化淀粉胶粘剂的粘度、失水率、初粘性、流动性、贮存期等性能进行测试.[结果]在相同条件下,用双氧水制备的马铃薯淀粉胶粘剂的各个性能都明显优于其他氧化剂制备的胶粘荆.[结论]双氧水是制备马铃薯氧化淀粉胶粘剂最合适的氧化剂.
