The Condensation Reaction of Starch

The microstructure of starch is a macromolecular ring structure composed of glucose groups. Starch with -OH group in its structure can react with many interesting chemical reagents to obtain a series of starch derivatives. Starch and starch derivatives have attracted the attention of researchers because of their special structure, a wide range of sources, renewable and biocompatibility, and green environmental protection. In the preparation method of starch derivatives, the condensing reaction is a Chemical Modification method with high efficiency and a simple preparation process. The condensing reaction of starch is a chemical reaction that changes the microstructure of starch by reacting the coupling agent with the hydroxyl functional group of starch after condensation and curing under the right conditions. The properties of starch derivatives obtained by condensation are slightly different from those of natural starch, and their application range is wider.

Our Technologies

Starch and starch derivatives play an irreplaceable role in the food processing industry, medical industry, and textile industry. Therefore, it is necessary to develop a specific way of chemical modification of starch as comprehensively as possible. At CD BioGlyco, we provide a One-Stop Service to starch production including extraction, modification (condensing reaction), and structural analysis.

• Starch modification service
  At CD BioGlyco, we will select a suitable coupling agent to react with natural starch to prepare modified starch, with an annual output of 400000 tons.

• Structural characterization and performance test service
  For the microstructure of starch, CD BioGlyco rovides nuclear magnetic resonance (NMR), mass spectrometry (MS), infrared (IR), ultraviolet-visible (UV), and scanning electron microscope (SEM) to analyze the structure of starch. For starch properties, CD BioGlyco will provide pH, solubility, thermogravimetric, mechanical, and viscosity tests.
