Product Name:D-Fructose
English Name:D-Fructose
CAS No.:57-48-7
Aliases:D-arabino-2-hexulose, D-levulose, D(-)-fructose, Fruit sugar
Molecular Formula:C6H12O6
Physical Properties:White odorless crystalline powder or crystals, strongly hygroscopic. Sweet taste, about 1.6 times as sweet as sucrose, the sweetest among sugars. Melting point (decomposed) 103–105°C (β-form); density approx. 1.6 g/cm³. Exists in α- and β-forms with specific rotation [α]D20 of -63.6° and -135.5° respectively; equilibrated aqueous solution shows [α]D20 of -92.3°. Readily soluble in water, soluble in methanol (1 g/14 mL) and ethanol (1 g/15 mL), insoluble in ether. Naturally present in honey and fruits.
Uses:Nutritive sweetener, processing aid, and excipient. A high-quality sweetener with strong, pure sweetness suitable for various foods. Due to its good hygroscopicity, it is especially suitable for moisture-retention foods and confectionery to prevent crystallization, mainly used in candy and beverages.
