L-Arabinose

L-arabinose, also known as gum aldehyde sugar or pectin sugar, is a pentose sugar with the chemical formula C5H10O5. L-arabinose rarely exists in the form of monosaccharides in nature, and usually combines with other monosaccharides to exist in the form of heteropolysaccharides in colloids, hemicellulose, pectin acid, bacterial polysaccharides, and certain glycosides. It has high stability to heat and acid.

1,inose is stable and does not decompose at high temperatures, making it suitable for use in baked goods. Soft cookie is a kind of biscuit loved by Americans, but its sugar content is high, which is easy to cause obesity. Therefore, adding L-arabinose in such biscuits can inhibit the absorption of sucrose, so that people can reduce their fear of obesity caused by high sugar biscuits. Similarly, adding a certain amount of L-arabinose to high calorie baked goods such as cakes and egg yolk pies can reduce the unit energy density and attract more consumers.

2,The application of L-arabinose in beverages. With the increasing improvement of people's living standards and the strengthening of consumers' health awareness, the structure of people's beverages has also undergone significant changes. The market for high calorie beverages has been declining year by year, while low sugar beverages, sugar free beverages, tea beverages, dairy beverages, plant protein beverages, fruit and vegetable juice beverages and other nutritious, health preserving, and functional beverages have gradually become the mainstream of the market. The addition of L-arabinose products in various beverages meets people's needs.

3,The application of L-arabinose in biomedicine. L-arabinose can be used to synthesize antiviral drugs such as nucleoside analogues. L-arabinose is used as raw material to synthesize 2-deoxy-2-fluoro-5-me~hyl - β - L-arabinose uracil (L-FMAU). L-FMAU is an effective active agent against hepatitis B virus (HBV) and Ep stein Barr virus.

4,The application of L-arabinose in other fields. Using L-arabinose as raw material, rare sugar alcohol - arabitol can be prepared through hydrogenation synthesis reaction, which is used in microbial fermentation and genetic improvement experiments; It can also be used to synthesize L-ribose, an important pharmaceutical intermediate with anti AIDS, anti-virus and anti-cancer drugs; It can also prepare arabinose reactive essence that can produce soft, rich aroma and flavor.

• Inhibit metabolism and absorption. The most representative physiological function of L-arabinose is to selectively affect sucrase in the small intestine, thereby inhibiting the absorption of sucrose.
• Inhibit blood sugar and fat. L-arabinose, as a low calorie sugar, inhibits the increase in blood sugar caused by sucrose intake, thus suppressing obesity, preventing and treating diseases related to high blood sugar.
• L-arabinose contains aldehyde groups in its molecular structure and is a reducing monosaccharide. When mixed with sucrose to prepare baked goods, it undergoes Maillard browning reaction with amino acids, proteins and other substances in the dough, making the flavor and color of baked products more unique and bright. In addition, the amount of L-arabinose added to baked goods can generally be determined according to the actual situation, usually not exceeding 5%. Adding L-arabinose can affect the rheological properties, taste, processing technology, etc. of dough, making the baked goods more delicious. Adding L-arabinose to fried foods such as fried chicken nuggets, roasted chicken, grilled meat, etc. will give them a richer aroma and enticing color.
