Implication
Review demonstrates distinct physicochemical changes in granular starch following annealing and heat-moisture treatment, highlighting mechanisms of structural preservation.
Key Points
- To review the impacts of annealing and heat-moisture hydrothermal treatments on the structural and physicochemical properties of granular starch.
- Synthesized findings on starch granule incubation under excess or intermediate moisture conditions (annealing) versus low moisture conditions (heat-moisture treatment).
- Evaluated thermal treatment dynamics occurring above the glass transition temperature but strictly below the gelatinization temperature.
- Hydrothermal modifications preserve external granular morphology while altering crystallinity, double-helix content, amylose-lipid complex formation, and gelatinization behavior.
- Treatment parameters modulate swelling power, pasting properties, gel strength, and susceptibility to both acid and enzymic hydrolysis based on moisture availability.
