摘要： Experimental investigation of molecular structure, pasting properties, and post-prandial blood sugar (PPBS) is performed using the kinetics of in vitro starch hydrolysis on jackfruit seed starch (JFSS), cassava starch (CS), potato starch (PS), maize starch (MS), wheat starch (WS), and rice starch (RS). The results show that JFSS displays smaller and smoother granule morphology, a higher amylose content (27.01%), a greater proportion of B3+ chains (12.83%), and a lower proportion of B1 chains (36.08%) than CS, MS, WS, and RS. JFSS also has higher values for weight-average molar mass (2.09 x 10(7) g mol(-1)), gelatinization temperature (88.15 degrees C), peak viscosity (3539 cP), final viscosity (5153 cP), and crystallinity (29.39%) than CS, MS, WS, and RS. Due to the above properties, JFSS displays lower values for the equilibrium constant (C-infinity; 35.80%), kinetic constant (k; 0.62 h(-1)), hydrolysis index (HI; 41.43), and prediction of postprandial blood sugar (PPBS; 62.45) than the other A-type starches CS, MS, WS, and RS. Furthermore, the experimental results indicate that JFSS is a middle-level glucose food group.
