摘要

Starch is a crucial carbohydrate with broad structural and functional characteristics depending on its botanical origin. However, native starches often lack desirable properties such as thermal stability, solubility, and gelling capacity, limiting their applicability in modern food formulations. Fermentation presents natural, and sustainable alternative to chemical modification, enhancing starch functionality through microbial activity which is primarily by lactic acid bacteria and yeasts. These microbes generate organic acids, enzymes, and gases that restructure starch granules, leading to improved digestibility, bioactivity, swelling power, solubility, and rheological behavior. These fermented starches exhibit a lower glycemic index, higher dietary fiber content, and potential probiotic effects, making them ideal for use in functional and therapeutic foods. Analytical techniques such as x-ray diffraction, scanning electron microscopy, and differential scanning calorimetry validate the structural and thermal alterations induced by fermentation. These modified starches demonstrate superior expansion characteristics and are widely employed in traditional and gluten-free baked goods. Advances in microbial strain selection and post-fermentation drying processes have further improved consistency and functional quality of fermented starches. Their alignment with health-oriented consumer trends highlights their promise for industrial-scale adoption. As demand for sustainable and functional ingredients grows, fermented starches represent compelling innovation pathway for next-generation food product development.
