Product Description

Description	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.
Chemical Properties	white to off-white crystalline powder
Chemical Properties	D(+)-Trehalose dihydrate occurs as virtually odorless, white or almost white crystals with a sweet taste (approximately 45% of the sweetness of sucrose).
Uses	D-(+)-Trehalose is a disaccharide composed of two α-glucose units. D-(+)-Trehalose is used in many processed foods as well as in biopharmaceutical monoclonal antibody formulations. D-(+)-Trehalose is also used as a protein stabilize.
Uses	Food additive; pharmaceutical excipient
Uses	An osmolyte, chemical chaperone, and inducer of autophagy.D-(+)-Trehalose is a disaccharide composed of two α-glucose units. D-(+)-Trehalose is used in many processed foods as well as in biopharmaceutical monoclonal antibody formulations. D-(+)-Trehalose is also used as a protein stabilizer.
Uses	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.
Production Methods	Trehalose is prepared from liquefied starch by a multistep enzymatic process. The commercial product is the dihydrate.
General Description	Trehalose is a naturally occurring disaccharide which is used as a nontoxic cryoprotectant of enzymes, membranes and vaccines. It serves as a carbohydrate reserve in microorganisms and protects them from adverse conditions.
Pharmaceutical Applications	D(+)-Trehalose dihydrate is used for the lyoprotection of therapeutic proteins, particularly for parenteral administration. Other pharmaceutically relevant applications include use as an excipient for diagnostic assay tablets; for stabilization during the freeze-thaw and lyophilization of liposomes; and for stabilization of blood cells, cosmetics, and monoclonal antibodies. Trehalose may also be used in formulations for topical application.
Biochem/physiol Actions	Trehalose is a non-reducing sugar formed from two glucose units joined by a 1-1 alpha bond. It is thought to provide plants and animals with the ability to withstanding periods of dehydration.
Safety	Trehalose is used in cosmetics, foods, and parenteral and nonparenteral pharmaceutical formulations. It is generally regarded as a relatively nontoxic and nonirritant material when used as an excipient. In the gut, trehalose is rapidly metabolized to glucose by the specific enzyme trehalase. A small minority of the population exhibits a primary (hereditary) or secondary (acquired) trehalase deficiency and thus may experience intestinal discomfort after ingestion of excessive amounts of trehalose owing to the osmotic activity of undigested trehalose in the gut. However, smaller amounts of trehalose are tolerated by such individuals without any symptoms. Trehalose is used as a sweetener and is reported to have substantially less cariogenic potential than sucrose.

storage	Trehalose is a relatively stable material. At 60°C for 5 hours it loses not more than 1.5% w/w of water (the dihydrate water of crystallization is retained). Open stored powder may liquefy at high relative humidity (≥90%). Trehalose should be stored in a cool, dry place in a well-sealed container.
Purification Methods	α,α-D(+)-Trehalose crystallises (as the dihydrate) from aqueous EtOH. Dry it at 13o. For the anhydrous compound dissolve 10g in pyridine (200mL) and distil off this solvent at atmospheric pressure, and when the temperature rises to 115.3o all the H2O is removed and 73mL of distillate is collected. Most of the anhydrous material crystallises out at this stage. The crystals are collected (6.8g), washed with Et2O to give 6.1g of anhydrous product. Higher yields are obtained by slightly more prolonged distillation. [Birch J Chem Soc 3489 1965, X-ray cryst: Brown et al. Acta Cryst 28 3145 1972, Beilstein 17/8 V 3.]
Incompatibilities	Trehalose is incompatible with strong oxidizing agents, especially in the presence of heat.
Regulatory Status	GRAS listed. In the UK trehalose may be used in certain food applications. Included in parenteral and nonparenteral investigational formulations.
