Physico-chemical Properties and Structural Analysis of Modified Potato Starch

Abstract

Abstract: Modified starches were prepared from native potato starch through introducing acetic ester groups and their structural characteristics were analyzed by FT-IR and SEM. Oxidized potato starch, potato starch acetate and oxidized potato starch acetate exhibited better transparency, adhesiveness and spreadability when compared to native potato starch. FT-IR analysis revealed the presence of characteristic absorption peak of carboxyl groups in oxidized potato starch and the formation of acetate groups in oxidized potato starch acetate. SEM observation showed the spherical or ellipsoidal shape and smooth surface of oxidized potato starch, no detectable change in the shape of potato starch acetate granules, but with poor regularity, and intact oxidized potato starch acetate granules with a low degree of substitution as a result of estertification on their rough surfaces.

Key words: modified starch, oxidization, acetate, oxidized-acetate, physico-chemical properties
