摘要：

For short amylose chains (DP 15), the solid state transition from the hexagonal B to monoclinic A crystalline type was detected by X-ray powder diffraction and differential scanning calorimetry (DSC). It occured on the minute time scale in the range 20-40% H2O dry basis (d.b.) for temperatures around 130-90-degrees-C, whereas similar 'Heat Moisture Treatments' of Sair. L. (1967, Cereal Chem.. 40,8) required hours with native maize starch granules at 20% H2O d.b.
