It can also be synthesized from sucrose and produced from Penicillium spp.、Erythorbic acid can also be prepared by reacting 2-keto-D-gluconate with sodium methoxide、synthesized from sucrose、or naturally produced by Penicililum species. Sodium erythorbate is prepared from D-glucose by a combination of biosynthesis and chemical synthesis via the intermediate 2-keto-D-gluconic acid.、Erythorbic acid is produced by the fermentation of D-glucose to 2-keto-D-gluconic acid by Pseudomonas fluorescens bacteria. The fermentation product is esterified and heated in basic solution to yield sodium erythorbate. Upon acidification of the salt in a water-methanol solution、erythorbic acid is formed.、Formulations、Preparations: Mercate "20"、Neo-cebitate.、Sodium Erythorbate、Grade: FCC.、U.S. Production: 2023: 400、000 - <550、000 lb、2022: 550、000 - <1、000、2021: 400、2020: 400、(1972) Probably > 4.54 x 10+5 g、(1975) Probably > 9.1 x 10+5 g、D-erythro-Hex-2-enonic acid、.gamma.-lactone is listed as a High Production Volume (HPV) chemical (65FR81686). Chemicals listed as HPV were produced in or imported into the U.S. in >1 million pounds in 1990 and、or 1994. The HPV list is based on the 1990 Inventory Update Rule. (IUR) (40 CFR part 710 subpart B、51FR21438).、Production volumes for non-confidential chemicals reported under the Inventory Update Rule. [Table#1682]、Production volume for non-confidential chemicals reported under the 2006 Inventory Update Rule. Chemical: D-erythro-Hex-2-enonic acid、.gamma.-lactone. Aggregated National Production Volume: 500、000 to < 1 million lbs.、General Manufacturing Information: Not Known or Reasonably Ascertainable、All Other Chemical Product and Preparation Manufacturing、Plastics Material and Resin Manufacturing、Paint and Coating Manufacturing、Food、beverage、and tobacco product manufacturing、.gamma.-lactone: ACTIVE、Has one-twentieth of the vitamin C activity of L-ascorbic acid、...Used to prevent nitrosoamine formation from nitrites in cured meats such as bacon.、Mid regulation、limitations: to accelerate color fixing in cured pork and beef cuts and cured comminuted meat food products、3、4 ounce to 100 lb meat or meat by-product. |
