ABSTRACT:This paper mainly studies the preparation of corn short amylose starch. In this paper, corn starch was used to treat corn starch, and the film-forming properties of starch were improved. The cornstarch was heated and the gelatinized and centrifuged. In this paper, the preparation method of green, green and safe amylose was explored, and the content of the high content of high content amylose was 8.91%, and the high content of short-chain starch was 49.15%, and the high-content branched starch was 27.5%. The molecular weight of adhesive is tested and the different composition of starch (DSC), differential scanning calorimeter test, shows that the combination of amylose and amylopectin limits the structural integrity of starch, amylose crystallization inhibition of pullulan, make ordinary corn starch granules for semi crystalline state, limits the material aspects of the application of starch, starch components separation as the basis of starch materials processing steps.
