Abstract
In this paper, B-type microcrystalline starch made a combination with hexanol in the case of water and alcohol as solvent respectively, V-type amylose-hexanol complexes were prepared. Obtained V-type amylose-hexanol complexes were characterized with scanning electron microscopy, X-ray diffraction, differential scanning calorimete. The results showed that using the preparation of water and alcohol solvents, obtained V-type amylose-hexanol complexes were hydrates and anhydrous crystal respectively. Hydrate crystal’s particles adhesion were serious, the particle diameter of anhydrous crystalline was 0.5~1μm, the crystallinity of both were above 70%. The V-type complexes prepared by aqueous solvent method and alcohol solvent method had almost the same melting temperature, the melting temperature of hydrates and anhydrous forms crystal were 70.7°C and 69.36°C.
