N2 - This study investigated the effects of using infrared heat-moisture treatment (IRHMT) on the properties of maize starch paste complexed with stearic acid (SA). Scanning electron micrographs showed that starch granules ghosts from IR HMT starch with SA did not show significant granular disintegration in comparison to conventionally HMT starch paste. The resistant starch (RS) content increased with SA-IR HMT, while extended pasting increased slowly digestible starch (SDS) content in IR HMT starch alone. The V polymorphs observed in XRD and DSC, and increased crystallinity from FTIR supported the changes in the properties of IRHMT starches. To a greater extent, the SA-IRHMT exerted more changes on starch micro- and molecular structural properties, and digestibility properties compared to conventional heat-moisture treatment (CHMT).
