Resistant dextrin, also known as digestion-resistant maltodextrin, is a soluble dietary fiber derived from starch. Produced through a controlled enzymatic process, resistant dextrin is characterized by its resistance to digestion in the small intestine, reaching the colon where it serves as a substrate for beneficial gut bacteria. With a neutral taste and excellent solubility, it is commonly used in the food industry as a functional ingredient. Resistant dextrin offers several health benefits, including supporting digestive health by promoting the growth of probiotic bacteria, aiding in weight management due to its low-calorie content, and contributing to blood sugar control. As a versatile dietary fiber, resistant dextrin has found applications in a variety of food products, including beverages, baked goods, and nutritional supplements, providing manufacturers with a tool to enhance the nutritional profile of their offerings.
