Fast delivery time, competitive price, huge production capacity

1.1 Product Introduction 

L-Arabinose, also known as L-Arabinose, is a natural five-carbon rare sugar, widely found in the hulls of fruits and coarse grains, and is also known as L-gum aldulose and pectinose, as it was originally isolated from gum arabic.

L-arabinose is a kind of low-calorie functional monosaccharide, it has sweetness itself, the sweetness is about 60% of sucrose, basically not absorbed by the human body, and will not cause changes in blood glucose, it can also inhibit the activity of sucrase enzyme in the human intestinal tract, so as to inhibit the human body's absorption of sucrose, and sucrose compounding and use, in order to ensure that the original product texture and physicochemical properties at the same time, but also can reduce the GI value of the food, it is an ideal natural It is an ideal natural low-calorie sweetener.

1.2 Physical and chemical properties 

L-arabinose is a kind of five-carbon aldose (pentanal sugar), molecular formula for C5H10O5, at room temperature for the white crystalline powder, odorless, sweet taste (sweetness of 60% of sucrose), easily soluble in water and glycerol, but the solubility is lower than that of sucrose; insoluble in ethanol, ether and acetone; belongs to the reducing sugar, the melting point of 154 ~ 158 ° C, the stability of the heat and acid is high; Specific rotation +100°~ +104°, with variable rotation phenomenon.

Applications 
Food :  Healthy sugar substitute, directly added into food or beverage, used in diabetic food, diet food, health function food, etc.; as a sucrose additive, compounded with sucrose, to reduce the GI value of food.
Health care products:  Directly market high-purity L-arabinose in the form of chewable tablets, capsules and powders, and add the raw material of hypoglycemia to be used as hypoglycemic health care products.
Pharmaceuticals:  As synthetic pharmaceutical intermediates, it can be used to synthesize nucleoside analogues and other antiviral and anticancer drugs, and currently there are two such anti-hepatitis B virus drugs; as pharmaceutical excipients and fillers, it is used in different dosage forms such as cough syrups, tablets and so on.
Chemical : As intermediate for synthesis of flavors and fragrances.
