Isomaltohexaose is widely utilized in the food and beverage industry as a functional oligosaccharide. It serves as a prebiotic, promoting the growth of beneficial gut bacteria, which enhances digestive health and boosts the immune system. In the production of health-focused foods, it is incorporated into dietary supplements, functional beverages, and dairy products to improve their nutritional profile. 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 makes it suitable for use in baked goods, confectionery, and fermented foods. Beyond food applications, isomaltohexaose is also explored in the pharmaceutical industry for its potential in developing gut health-related therapies and as an ingredient in oral care products to support oral microbiome balance.
