Relativity on Granularity and Molecule Characteristics of KGM

In this paper, the relativity on the granularity with different mesh of konjac glucomannan(KGM) and molecular dimension was discussed. Laser particle size analyzer and laser light scattering were used to analyze the granularity distribution and molecular characteristics of KGM. The results showed that the granularity of KGM was gradually decreased after gradient refining. The Mw of KGM was gradually decreased with its granularity decrease and its molecular conformation was from globular to linear structure.
