1-Kestose

470-69-9

1-Kestose is a trisaccharide and the smallest unit of inulin-type fructans. Its structure consists of two fructose units linked to a terminal glucose unit. Found naturally in plants like chicory and onions, 1-kestose is a non-digestible carbohydrate for humans, making it an effective prebiotic. It is widely used as a functional food ingredient to selectively stimulate the growth of beneficial gut bacteria, thereby improving intestinal health.
