Highly cost-effective wheat starch-stearic acid complexes enabled by microwave processing: Structural properties, anti-digestion, and molecular dynamics simulation.

Microwave (MW) heating shows higher efficiency in preparing wheat starch-stearic acid (WS-SA) complexes than the traditional water bath (WB) heating method, while the detailed "time-energy-quality" evaluations and the potential anti-digestion mechanism of the MW-processed WS-SA remain further exploration. In this study, 95 % time cost and 73 % energy consumption were saved when using MW processing WS-SA, and the MW-processed complexes were verified to show significantly higher relative crystallinity, short-range ordered structure degree, thermal stability, complex index, and resistant starch content. Molecular dynamics (MD) simulation demonstrated that MW treatment notably facilitated the binding rate of amylose and SA molecules, generating a tight and stable helical structure through hydrogen bonds and van der Waals forces.
