Insights into Dual\nSelf-Assembly Mechanisms in Various Artocarpus altilis (Parkinson) Fosberg Starch-Endogenous\nLipid-Endogenous Protein Complexes: Interactions between Digestibility\nKinetics and Multiscale Structure

Chinese seedless breadfruit is rich in starch, lipids,\nand protein.\nTo explore the interactions among these macromolecules during food\nprocessing, the seedless breadfruit starch-endogenous lipid-endogenous\nprotein complex was investigated. Native seedless breadfruit starches\nare categorized as low-resistant-content starch [low-resistant starch\n(LRS)] or high-resistant starch (HRS). After complexation, dual self-assembly\nmechanisms occur after complexation. Initially, for the LRS group,\nlong chains of amylopectin and amylose participate in complexation\ndue to the migration from the short side chain of amylopectin, leading\nto an increase in RS content compared to the native starch. In contrast,\namylose participated in complexation in the HRS group, which showed\nhigher digestibility than that of raw starch. According to chemometric\nanalysis, the HRS group complex possesses a more compact external\nand internal nanomicrostructure, leading to its weaker digestibility\nkinetics compared to the LRS group complex. This study provides a\nfundamental basis for the comprehensive application of novel multicomponent\nfoods.
