摘要

本文以氯化甘油为醚化剂，通过改变醚化剂/淀粉的反应物比(v/w)制备了甘油淀粉。测定了甘油淀粉的摩尔取代量。介绍了一种改进的比色法测定摩尔取代的方法。采用傅里叶变换红外光谱(FT-IR)和核磁共振氢谱(1H NMR)对甘油淀粉进行了表征。实验分析了二羟丙基化对一系列淀粉性能的影响，包括结晶度、颗粒形态、糊状清晰度和退化稳定性，并将其与天然玉米淀粉进行了比较。

Synthesis and characterization of glyceryl starch and determination of molar substitution

In this work, glyceryl starch was prepared by changing the reactant ratio (v/w) of etherifying agent/starch using chlorinated glycerol as etherifying agent. The molar substitution of glyceryl starch was determined. The modified colorimetric method for the determination of molar substitution was described. The glyceryl starch was characterized by using FT-IR and ¹H NMR spectroscopy. Experimental analyses were performed to investigate the effect of dihydroxypropylation on a range of starch properties, including degree of crystallinity, granule morphology, paste clarity, and retrogradation stability and compare them with those of the native corn starch.

期刊介绍： The scope of the journal is to publish original contributions and reviews on studies, methodologies, instrumentation, and applications involving the analysis and characterization of polymers and polymeric-based materials, including synthetic polymers, blends, composites, fibers, coatings, supramolecular structures, polysaccharides, and biopolymers. The Journal will accept papers and review articles on the following topics and research areas involving fundamental and applied studies of polymer analysis and characterization: Characterization and analysis of new and existing polymers and polymeric-based materials. Design and evaluation of analytical instrumentation and physical testing equipment. Determination of molecular weight, size, conformation, branching, cross-linking, chemical structure, and sequence distribution. Using separation, spectroscopic, and scattering techniques. Surface characterization of polymeric materials. Measurement of solution and bulk properties and behavior of polymers. Studies involving structure-property-processing relationships, and polymer aging. Analysis of oligomeric materials. Analysis of polymer additives and decomposition products.
