Physicochemical Properties of Germinated Corn Starch

Abstract
|
|
|
|
Physicochemical properties of starch isolated from germinated corn were investigated and compared with those of nongerminated corn starch. Amylose content and initial gelatinization temperature of germinated starch were lower than those of nongerminated starch. Swelling power and solubility of both starches exhibited two stage behavior, however germinated starch revealed lower swelling power and higher solubility compared to those of nongerminated starch. Both starches showed a typical A type X-ray diffraction and irregular oval shape including partly polygon with the size of 10-25㎛. However, germinated starch showed many holes with the size of 1-2㎛ on the surface of granule.
