Diets containing high amylose vs amylopectin . × Close Log In.The current study aimed to obtain the amylose and amylopectin fractions from potato, banana, corn, and cassava starches, characterize them, and evaluate their behavior via thermogravimetric curves.
Variations in the amylose content can affect the physicochemical and functional .
78 (2):111–115 Amylose and amylopectin were prepared from large, medium, and small granule starches of classified waxy barley flour, and their fine structures were investigated. Chromatographic techniques lined in Fig. Waxy starches contain very little or zero amylose, and some high amylose starches contain much higher content (>50%) of amylose, including amylose-only genetically.Amylopectin is the main component by weight, whereas amylose content varies between 15% and 30% for most starches [1].Our results showed that appa rent amylose content ranged from 14.
