  • Applications

    1-Kestose, an oligosaccharide in the fructooligosaccharide family, is commonly used as a prebiotic ingredient in foods and dietary supplements to promote the growth of beneficial gut bacteria. It may be included in functional foods and beverages aimed at supporting digestive health. In cosmetics and personal care, it may serve as a humectant and conditioning agent; in food processing, it can act as a low-calorie sweetener and texturizing component; and in animal feeds, it is evaluated for use to support gut health.
