Effect of Particle Size on the Water-Soluble Substances and Microscopic Structure of Sorghum Straw Powder

Abstract:

The effect of particle size on the water-soluble substances and microscopic structure of sorghum straw powder were investigated. Sorghum straw powder with four particle size (300 ~ 450μm, 125 ~ 150μm, 97 ~ 105μm, 330 ~ 420nm ) were studied for analysing changes of water-soluble substances and microscopic structure. The results showed that with the particle size decreasing the pH value of water-soluble substances decreased, the concentration of reducing sugar in water increased firstly then began to decrease when it reached to a certain value, the crystallinity of sorghum straw powder decreased, and the degree of polymerization of sorghum straw was lowered ,respectively.
