This ingredient is commonly added to health foods, beverages, and dietary supplements to support gut microbiome balance. Additionally, it is used in low-calorie and sugar-free products as a sweetener alternative, providing a mild sweetness without significantly impacting blood sugar levels. Its stability under various processing conditions makes it suitable for baked goods, dairy products, and fermented foods. Gourmet oligosaccharide is also incorporated into animal feed to improve gut health and overall well-being in livestock and pets.
