C6H7NaO6 Biological Antimicrobial Food Preservatives 98.0-100.5% Assay

New Type Of Biological Food Anti - Oxygen And Antiseptic D-Sodium Erythorbate

D-sodium erythorbate,It is a new type of biological food anti - oxygen and antiseptic.

Molecular formula: C6H7NaO6.olecular weight: 216.12 melting point 200 ℃. White or slightly yellow crystalline granules or powders, odorless, slightly salty, soluble in water (about 7mL of water soluble 1g). The dry state is stable in the air, and the air, trace metals, heat and light are liable to deteriorate when aqueous solution.

Preparation

With glucose as raw material, vaccination fluorescent bacillus of the genus pseudomonas, fermentation by ventilation, alpha ketone calcium gluconate, after acidification, in addition to calcium, add methanol and a small amount of sulfuric acid on the esterification, get solid glucose acid methyl ester. Dissolve the ester in methanol, add metal sodium, and heat the mixture to produce the sodium salt of the isoascorbic acid. After separation, the product can be refined

d-sodium erythorbate is an important antioxidant in the food industry antistaling agent, can keep food color, natural flavor, extend the shelf life, and without any side effects, in the food industry, mainly used in meat, fruits, vegetables and canned, jam, beer, soft drinks, fruit tea, fruit juice, wine, etc.
