Dextrin Dextrin is a versatile carbohydrate polymer derived from starch, functioning as a binder, thickener, stabilizer, and encapsulant that provides film-forming properties, controlled viscosity, and moisture retention for improved texture, adhesion, and shelf life in dry and wet formulations. In the food industry, it offers clean-label solubility, low sweetness for neutral flavor impact, rapid hydration, and digestibility as a soluble fiber source ideal for processed foods, coatings, and functional ingredients.
