What Is Starch Polymerization Degree
The starch polymerization degree (DP) refers to the number of glucose units that make up a starch molecule, representing its chain length and structural complexity. Depending on the linkage type between glucose residues, starch can be classified as:
Kadokawa, JI. et al. Polymers. 2012.

The degree of polymerization directly affects starch crystallinity, gelatinization properties, and digestion rate. Measuring DP provides insight into molecular structure and distribution, serving as a foundation for studying starch processability, nutritional functionality, and material performance.
