Abstract ：
The study aimed to investigate the cooperation of maize starch and ferulic acid under physical mixing (PM), heat treatment (HT) and extruded treatment (ET) and its impacts on postprandial blood glucose level. PM did not influence the surface structure, or long/short-range order of maize starch, yet it decreased rapidly digestive starch (RDS) content to 65.82 +/- 1.67% and increased resistant starch (RS) content to 20.58 +/- 1.71%. In the HT group, maize starch-ferulic acid (HMS-FRA) complexes was formed, maintaining A-type crystal structure, and binding amount increased as the addition of ferulic acid increased. And maize starch had the lowest RDS and highest RS, moreover, its postprandial blood glucose value was 7.93 +/- 0.64 mmol/L center dot h when added 2.0% (w/w) ferulic acid. Besides, in the ET group, the crystal type of extruded maize starch-ferulic acid (EMS-FRA) complexes changed to A + V type. ET also led to increased RS content, with postprandial blood glucose level significantly reduced (6.16 +/- 0.80 mmol/L center dot h) in EMS-2.0FRA. These results demonstrated that ferulic acid could form maize starch-ferulic acid complexes through ET, and effectively reducing its postprandial blood glucose level. Our results will provide an idea for the production of functional staple food.

Abstract ：
Recent studies show that starch-polyphenols complexes exert positive effects on gut health, but the probiotic effects of maize starch-caffeic complexes remain underexplored. Therefore, this study aimed to investigate the probiotic effect of maize starch-caffeic complexes from the small intestine to the colon. First, maize starch was extruded with caffeic acid and subjected to in vitro digestion, and the undigested parts were fermented in vitro, and the structural characteristics, short chain fatty acids (SCFAs) and microbiota communities were investigated. Results showed that caffeic acid reduced the long/short-range order of maize starch after extrusion, significantly increasing resistant starch to 30.35 +/- 2.36 %. In vitro fermentation indicated that microbiota utilized the amorphous area of the residues first, promoting SCFAs production and the growth of Bifidobacterium and Lactococcus genus. Overall, the probiotic properties of extruded maize starch-caffeic acid complexes suggest they could serve as a functional food for health benefits.
