None

Storage method

Store in a cool place after airtight packaging.

Synthesis method

Use D-glucose as raw material, add bacteria or Bacillus subtilis for fermentation, and separate and refine the fermentation products.

Preservation of bacterial strains → Activated slope → Seed tank culture → Fermentation → Fermentation broth →

Flocculation → Supernatant → Cationic resin exchange → Activated carbon decolorization → Concentration

→Refined→Crystallized→Product

Purpose

D-ribose plays an important role in the pharmaceutical industry, food industry, agriculture and life science research. In the pharmaceutical industry, it is a very useful biochemical reagent, pharmaceutical and pharmaceutical synthesis intermediate. In the food industry, it can be used as a sweetener and condiment, as well as a crop growth promoter and feed additive.
