NINGBO INNO PHARMCHEM CO.,LTD. provides insights into the fundamental aspects of Sodium D-Isoascorbate, focusing on its chemical properties and production methods. Also known as Sodium Erythorbate (E316), this compound is a stereoisomer of sodium ascorbate and shares its potent antioxidant capabilities, making it invaluable in food preservation and other industrial applications. Understanding these core aspects is crucial for leveraging its full potential.

Chemically, Sodium D-Isoascorbate (C6H7NaO6) is the sodium salt of erythorbic acid. It typically appears as a white to off-white crystalline powder or granules, possessing a faint odor and a slightly salty taste. A key characteristic is its solubility in water, which is significantly higher than in ethanol. In its dry, crystalline state, it is relatively stable. However, when dissolved in water, it readily reacts with atmospheric oxygen and other oxidizing agents, a property that underpins its effectiveness as an antioxidant. The pH of its aqueous solutions typically falls within the range of 5.5 to 8.0, which is favorable for many food applications.

The production of Sodium D-Isoascorbate is primarily achieved through fermentation processes. Sugars, typically derived from corn or other starch sources, are fermented using specific microorganisms, such as Pseudomonas fluorescens or Arthrobacter globiformis, to produce 2-keto-D-gluconic acid. This intermediate is then chemically processed through esterification, transformation, and refinement to yield erythorbic acid, which is subsequently converted into its sodium salt. This biotechnological approach ensures a high-purity product suitable for demanding applications. Manufacturers often highlight the quality and consistency when discussing the sodium erythorbate price, as the production process directly impacts its value.

The dual nature of Sodium D-Isoascorbate – its stability in dry form and reactivity in solution – makes it a critical ingredient for controlling oxidative processes in foods. Its ability to accelerate curing reactions in meats and preserve color and flavor in various food products has led to its widespread adoption. The reliable supply and understanding of its production are essential for industries that rely on its antioxidant efficacy. Businesses looking to optimize their product formulations often seek to buy Sodium Erythorbate powder due to its proven performance and competitive sodium erythorbate price.
