general introduction:

Molecular formula: C5H10O5Relative molecular weight: 150.13L-Arabinose is white crystalline powder with sweet flavor and melting point of 154—158°C. It’s easily soluble in water and glycerol, slightly soluble in ethanol and not soluable in aether. It is highly stable under the condition of heat and acid. As low-calorie sweetener, it has been approved to be the healthy food additive by American Bureau of Food and Drug Supervision and Health and Human Services Department of Japan. Also it has been authorized new resource food by Health Department of China.Features and Function·Solubility It’s easily soluble in water and slightly soluble in ethanol.Its solubility is lower then granulated sugar.·SweetnessIts sweet flavour is similar to granulated sugar, while is 50% the sweetness of granulated sugar.·specific rotationMultirotation, specific rotation +100°→+104°(24h, H2O,c=5)Application·Food Industry: food for diabetics , diet food, healthy functional food and sucrose additive·Medicine: prescription and OTC drugs additive for diet or controlling blood glucose, drug excipient,intermediate of flavor and drug synthesisPhysiological Functions·Restrain metaboly and absorbility of sucrose ·Control rise of blood glucose·Restrain fat accumulation
