Characteristics of Starch

Starch is a kind of polysaccharide, which is widely used at present. It has been widely concerned by various industries because of its rich sources, low price, and renewability. The drawback is that natural starch still has some disadvantages, such as low emulsifying ability, poor water solubility, or insufficient stability. To further expand the scope of application of natural starch, it is necessary to find suitable technical methods to modify starch, and then change its characters. Physical, Chemical, and Enzymatic Methods are the most widely used and excellent methods in starch modification. The modification of natural starch by cross-linking reaction is a widely used chemical modification method.

Our Services

At CD BioGlyco, we have developed a variety of technical tools for the chemical modification of natural starches. We also supply to cross-linked starches analyze the structure and properties services.

• Cross-linking starch modification service

At CD BioGlyco, we use a suitable cross-linking agent to cross-link with natural starch, and then add graft monomers to further expand the reticular structure of cross-linked starch. Secondly, CD BioGlyco also provides screening of the most suitable reaction conditions for the production of cross-linked starch, such as time, temperature, pH, and the type of cross-linking agent.

• Testing and characterization service

CD BioGlyco provides FTIR, SEM, DSC, TG/DTG, and other testing services to comprehensively analyze the microstructure of cross-linked starch.
In terms of macroscopic properties, CD BioGlyco uses a national rotational viscometer to test the viscosity of cross-linked modified starch. In addition, the universal mechanical testing machine is a suitable testing equipment for the bonding strength of cross-linked starch.

Applications

• In the medical field, the production of crosslinked starch can be applied in the development process of lubricants for surgical rubber gloves.
• In the food processing industry, crosslinked starch is applied as a thickening and stabilizing agent for food products.
• In the textile industry, the production of crosslinked starch is applied as an additive in the production of textile articles.
