Physicochemical Properties: On Infrated Absorption Spectra of Native Starch and Modified Starch using Film

Abstract

The infrared absorption spectra of native (potato) and new modified starches were observed in about 4500cm^-1_??_670cm^-1 region using film technique as a new attempt. Deuteration was attempted to investigate the physicochemical properties and to assign the absorption bands partially. And the absorption band attributed to the H₂O molecule was explained, The absorption band, which appeared in the modified starch only and which was thought as one great difference bet-ween two starches seems to be related to CO.
