    Product Usage

    1. Antiscorbutic, antiviral
    2. Analgesic, antipyretic
    3. Physiological antioxidant. Coenzyme for a number of hydroxylation reactions; required for collagen synthesis. Widely distributed in plants and animals. Inadequate intake results in deficiency syndromes such as scurvy. Used as antimicrobial and antioxidant in foodstuffs.

    Production Methods

    Glucose is hydrogenated to N-sorbitol under the catalysis of nickel and then fermented with acetic acid mold at 30 to 34 ° C and Ph value of 5.2 to 5.5 to form L-sorbose. In the presence of fuming sulfuric acid and -8 ℃, L-sorbose and acetone condensation of diacetone sorbose; in the nickel sulfate catalytic and 75 ~ 80 ℃, and then sodium hypochlorite oxidation to produce diacetone-2-keto-L , Gulonic acid; finally hydrolyzed under acidic conditions to produce 2-keto-L-gulonic acid; and then get ascorbic acid.
