Molecular characteristics and physicochemical properties of very small granule starch isolated from Agriophyllum squarrosum seeds

Novel starch resources isolated from accessible botanical origins are of special interest to food scientists in the context of food security. In this study, Agriophyllum squarrosum starches (AS-1, AS-2, and AS-3) were isolated from three ecotypes of A. squarrosum seeds and compared with quinoa starc...

Description
Summary:Novel starch resources isolated from accessible botanical origins are of special interest to food scientists in the context of food security. In this study, Agriophyllum squarrosum starches (AS-1, AS-2, and AS-3) were isolated from three ecotypes of A. squarrosum seeds and compared with quinoa starch (QS). The mean particle diameter of AS granules ranged from 1.12 to 1.15 μm, and AS amylopectin had a significantly higher Mw than QS (p
