Trehalose is a non-reducing dissacharide that contains two α-glucose molecules linked by an α 1,1-glycosidic bond. Digestion of this substrate occurs in the intestine through the action of trehalase which produces glucose. It is usually found in beans, mushrooms, seaweeds and yeasts. Its physical properties include low sweetness, clean finish, an anti-aging effect on starch and a protein stabilizer.
