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.

Minute crystals or white powder. pH of aqueous solutions 5.6 to 7.0 or even higher (a 10% solution, made from a commercial grade, may have a pH of 7.4 to 7.7). (NTP, 1992)|Sodium ascorbate is an organic sodium salt resulting from the replacement of the proton from the 3-hydroxy group of ascorbic acid by a sodium ion. It has a role as a food antioxidant, a flour treatment agent, a coenzyme, a plant metabolite, a human metabolite, a Daphnia magna metabolite and a reducing agent. It is an organic sodium salt and a vitamin C. It contains a L-ascorbate.|A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant.

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.

Our Quality

As a professional ingredient supplier, we do not operate manufacturing facilities. Instead, we build robust quality‑assurance workflows across our whole supply chain to safeguard consistent product performance for every shipment

Strict Supplier Due‑Diligence

Before entering any partnership, we carry out on-site factory visits and assess industry reputation, followed by multi-stage qualification reviews. We validate production qualifications, export track records, quality management systems and complete certification packages. New suppliers must pass sample evaluation, and only fully vetted top-tier factories are admitted to our approved supplier pool

Batch‑by‑batch Document Verification

For every order, we cross‑check factory‑issued test documents against agreed specifications including FCC, USP, EP, AJI, CP or your customized requirements. We will not forward documents to customers until key indicators are fully aligned with specifications. This step avoids inconsistent or mismatched documentation common in raw‑material trade.

Independent Third‑party Testing Coordination

Upon client request, we can arrange independent laboratory inspections from recognized third‑party institutions. We manage sample delivery, test protocol communication and report follow‑up to support your market compliance needs.

Quality Closure & Continuous Improvement

We keep traceable records for all delivered batches. If any quality concern arises, we act as your single point‑of‑contact to trace root causes with source factories, drive corrective actions and deliver practical resolution plans. Client feedback is systematically collected to optimize our supplier management and document‑review procedures.

We provide a comprehensive set of compliance documents to support your import and registration work. Our available documentation includes but is not limited to:

★ ISO Certification ★ Halal Certificate
