Effects of amylose chain length and heat treatment on amylose-glycerol monocaprate complex formation

► The effects of amylose chain-length and heat-treatment on amylose-GMC complex formation were investigated. ► The longer amylose chains facilitated the amylose-GMC complex formation. ► Both type I and type II complexes were formed after the initial DSC heating. ► Only the type II complexes were formed after the prolonged heat treatment with improved crystallinity and thermostability.
