To understand how amylose content and crystal type regulated the digestibility of starch-lipid complex nano -particles, this study used waxy corn starch (WCS), normal corn starch (NCS) and high-amylose corn starch (HCS) with different amylose contents and NCS (A-type), potato starch (PtS, B-type) and pea starch (PS, C-type) with different crystal types to investigate the effects of amylose content and crystal type on the structure and di-gestibility of starch-lauric acid (LA) complex nanoparticles. A significant increase in complex index (CI), R1047/ 1022, relative crystallinity, and enthalpy ...
