【摘要】 本研究首先采用化学法、拉曼光谱、X-射线衍射仪和激光光散射技术等比较了福建省不同产地木薯淀粉以及马铃薯、番薯和芭蕉芋淀粉的理化性质，为木薯淀粉的深加工利用提供基础数据；其次通过催化剂的筛选和淀粉催化氧化反应的考察，解明了反应条件与氧化淀粉的羧基和羰基含量的关系，制备了高固含量、低粘度的淀粉糊液；接着首次采用先进的凝胶渗透色谱-激光光散射联用技术(GPC-MALLS)分析了各种催化氧化木薯淀粉的组分和分子结构，解析了催化氧化对木薯淀粉的分子结构与胶粘性能的关系；最后将上述理论研究成果应用于瓦楞纸淀粉胶粘剂的研制，确立了最佳的制备工艺条件，为低成本高强度快干型瓦楞纸淀粉胶粘剂的研制开辟了一条新途径。更多还原

【Abstract】 In this paper, chemical method, Raman spectra, X-ray diffraction method and MALLS were used to compare physical & chemical properties and structures of tapioca starches, potato starches, canna starches and other starches in Fujian province at first, in order to establish intact database and make good use of plant starches. Then, the relationship between reaction conditions and the carboxyl and carbonyl content was investigated by the selection of catalysts and the study of catalytic oxidation. Oxidized starches with high carboxyl and carbonyl content but low viscosity were prepared by catalytic oxidation. GPC-MALLS and other advanced methods were used first time to analyze the component and structure of catalytic oxidized tapioca starches and to determine the effect of catalytic oxidation on the structure of tapioca starch and its adhesive properties. Finally, above results were applied to prepare starch adhesive and the best prepared condition was established. It was meaningful to the preparation of starch adhesive with low cost but strong adhesive strength and fast drying speed.更多还原
