Trehalose is irreducibility disaccharide formed by two glucose molecules jointed with α,α-1, 1 keys. It is a kind of safe and reliable natural carbohydrate, is with outstanding performance for maintaining cell viability and biomacromolecule activity, and has an honor of “Life Sugar” In scientific community. The sweetness is only 45% of granulated sugar, the sweet taste is moderate. It can be used as a special food ingredient to prevent food spoilage, restrain the nutrient deterioration, maintain food fresh flavor and improve food quality; it is enormously expand the function of trehalose as natural edible sweetening agent. It is also the important components of cosmetic for maintaining cell viability and preserving moisture, and has achieved accreditation of American Generally Recognized As Safe (GRAS).
(1).It has high water retention capabilities, and is used in food and cosmetics.
(2).The sugar is thought to form a gel phase ascells dehydrate, which prevents disruption of internal cell organelles, by effectively splinting them in position. Rehydration then allows normal cellular activity to be resumed without the major, lethal damage that would normally follow a dehydration/rehydration cycle.
(3).Trehalose has the added advantage of being an antioxidant. Extracting trehalose used to be a difficult and costly process. Trehalose is currently being used for a broad spectrum of applications.
