Description and Uses

Trehalose is a natural non-reducing disaccharide composed of two α-glucose units. It is found in all major groups of organisms except vertebrates, has biological functions as an osmolyte, storage reserve, and stress protectant, and has diverse commercial applications. Trehalose can also induce or enhance autophagy.

Stabilizes cells during freezing, freeze-drying and air-drying. Sweetener and stabilizer in foods; cryoprotectant for freeze-dried foods. Additive in cosmetics and personal care products.
