Isomaltoheptaose is primarily used in the food and beverage industry as a functional ingredient due to its prebiotic properties. It promotes the growth of beneficial gut bacteria, such as Bifidobacteria and Lactobacilli, which can enhance digestive health and improve gut microbiota balance. This makes it a valuable component in dietary supplements, functional foods, and probiotic products. Additionally, it is used as a low-calorie sweetener in sugar-free or reduced-sugar products, providing a mild sweetness without significantly impacting blood glucose levels. Its stability under various processing conditions also makes it suitable for incorporation into baked goods, dairy products, and beverages. Beyond food applications, isomaltoheptaose is being explored for its potential in pharmaceutical formulations to support gut health and immune function. In the cosmetics industry, it serves as an ingredient in skincare products to enhance moisture retention and improve skin texture for a smoother feel.
