Advantages of Chemical Modification of Starch
Starch is a kind of environmentally friendly polymer compound with abundant content, biocompatibility, and biodegradability in nature. At present, starch can be used in various industries. To maximize the scope of application of starch, it is often necessary to adjust the microstructure of starch to change its physical, mechanical, and chemical properties. Chemical modification is one of the methods of starch modification, and it is also the most widely studied modification method because of its non-destructive and potential application value of modified starch.
Our Technologies
Chemical modification is most widely used in starch modification. CD BioGlyco will provide several methods of starch modification.
Etherification is a modification method by which hydroxyl groups are replaced by carboxymethyl, hydroxypropyl, or hydroxyethyl groups by forming an ether chain (ROR).
The starch with a high grid cross-linking structure has produced by selecting a suitable cross-linking agent and starch.
Starch grafting refers to the introduction of polymers into the skeleton of starch to change the structure of starch.
Condensation is a modification method in which starch loses one molecule of water while introducing new groups, thus changing the molecular structure of starch and improving its properties.
Phosphorylation of starch refers to a modified starch with a cross-linked structure obtained by the reaction of starch with a phosphorylation reagent.
Carboxymethylation of starch is a part of the etherification modification of starch. Carboxymethylated starch has some special properties: thickening, gelatinization.
Starch acidolysis produces small molecules of monosaccharides, disaccharides, and polysaccharides. This is also a way to produce glucose.
The cationization of starch is a process of reaction of starch, strong bases, and cationic compounds.
Starch esterification refers to the conversion of hydroxyl structure in starch to alkyl or aryl structure.This modification usually changes the degradation properties of starch.
Citric acid is a tricarboxylic acid, which can form anhydride under heating and then esterify with hydroxyl groups on starch to form starch citrate ester.
Applications
- In the medical industry, modification of starch can be applied to the development of certain physiologically active drugs, such as hypoglycemic drugs.
