Product Overview

Sodium Ascorbate (Vitamin C Sodium Salt, E301, CAS 134-03-2) is a white or slightly yellow crystalline powder. It is the sodium salt form of L-ascorbic acid, an antioxidant nutritional fortification ingredient with milder acidity. It supports immune function, collagen synthesis and enhances non-heme iron absorption. It is widely used in dietary supplements, functional food & beverage and animal feed formulations.

 

Character

Sodium Ascorbate is freely soluble in water. It is the sodium salt of L-ascorbic acid, featuring a milder pH value compared to L-ascorbic acid and less acidic. It retains full vitamin C nutritional activity. It is still sensitive to heat, light and oxidative conditions.

 

Main Functions

1.Antioxidant Activity: Acts as a potent water-soluble antioxidant, helps neutralize free radicals and reduce oxidative stress.

2.Immune Support: Supports normal immune system function and contributes to the body’s defense against oxidative challenges.

3.Collagen Synthesis Assistance: Essential cofactor for collagen formation, benefiting skin, connective tissue, cartilage and bone health.

4.Enhances Iron Absorption: Helps improve the absorption of non-heme iron from plant-based diets.

 

Application 

1.Dietary Supplements Applied in multivitamin tablets, capsules, effervescent tablets and nutritional powder blends, preferred for formulas requiring low acidity and mild taste.

2.Functional Food & Beverage Used in fortified drinks, fruit beverages, candies and baked goods for vitamin C enrichment. Its mild acidity helps avoid strong sour taste and reduce corrosion to production equipment.

3.Animal Feed Added into livestock, poultry and aquaculture feed premixes to meet animal vitamin C nutritional requirements and support animal growth and immunity.

Melting Point: 220 °C Boiling Point: 235 °C
Flash Point: 238.2ºC Refractive Index: 105.5 ° (C=10, H2O)
Water Solubility: H2O: 620 g/L (20 ºC) Storage Conditions: Store at RT.
Vapor Pressure: 1.62E-14mmHg at 25°C Flammability characteristics: Flammable; burning produces toxic sodium oxide fumes
Specific rotation: 104 º (c=1, H2O 25 ºC) Odor: Odorless
PH: Between 6,5 and 8,0 (10 % aqueous solution) Air and Water Reactions: Water soluble. Aqueous solutions are subject to quick air oxidation at pH greater than 6.0.
Reactive Group: Alcohols and Polyols Reactivity Profile: A weak base. Materials in this group are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH’s greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.
