Key Benefits of Ascorbic Acid
- Vitamin C Fortification
Ascorbic Acid is a concentrated source of water soluble Vitamin C. A small addition gets a beverage, cereal or supplement to its label claim without disturbing the rest of the formula.
- Antioxidant Protection
It is a strong reducing agent. It holds back changes in flavour, colour and nutrients during processing and storage. How far it goes depends on your pH, on how much oxygen gets in, and on whether there are metal ions around.
- Colour Retention in Meat and Seafood
It helps cured meat and seafood hold their colour and limits nitrosamine formation. Set the dose alongside your nitrite level, and check it against the curing rules of the destination market.
- Bread and Flour
Bakeries use it as a flour treatment agent. It builds dough strength and gas retention, which shows up in loaf volume and crumb. The dose is very small, and each market caps it under its own food additive rules.
- Acidity Contribution
Ascorbic Acid adds acid as well as Vitamin C. That is useful when a product needs a vitamin claim and a sharper acid profile at the same time. It is often used with citric acid, and the two need balancing against your target pH.
Certifications & Compliance
Kosher, Halal, ISO 22000 and FSSC 22000 documents are available depending on the order. COA, TDS, Allergen Statement and GMO statement come on request. Certificate samples are in the attachment. Tell us your grade and destination market, and we will confirm which documents apply.

FAQ
Q: Can you provide a COA for Ascorbic Acid?
A: Yes. We can provide batch-specific Certificates of Analysis (COAs) for the products supplied, upon customer request.
Q: Can I request a sample before placing an order?
A: We can provide samples for your product evaluation. Please provide your target grade, form, application area, required sample quantity, company name, shipping address and target market. Sample supply and express delivery arrangements need to be confirmed separately.
Q: What grades of Ascorbic Acid are available?
A: Oriental Tongxiang supplies food-grade Ascorbic Acid as standard. Pharma grade (BP / USP / EP ) and feed grade can be discussed according to your specification and order requirements.
Q: Is Ascorbic Acid the same as Vitamin C?
A: Yes. Ascorbic Acid is Vitamin C, and it is also written as L-Ascorbic Acid. The food additive number is INS 300 / E300.
Q: What physical forms are available?
A: Fine powder and granular forms are available, and a direct-compression grade can be discussed for tableting. Particle size affects flow, dust level and tablet weight uniformity, so please specify the mesh range you need.
Q: Is Ascorbic Acid the same as Sodium Ascorbate?
A: No. Sodium Ascorbate (INS 301 / E301) is the sodium salt of ascorbic acid. It is less acidic and contains less Vitamin C per unit weight, so the two are selected according to the target pH and the required vitamin level.
Q: How should Ascorbic Acid be stored after delivery?
A: Please store it in a sealed container in a cool, dry and dark place, avoiding direct sunlight, moisture, heat and contact with strong odors. Ascorbic Acid is sensitive to light, heat, moisture and air, so reseal opened cartons promptly.
Q: Is Ascorbic Acid stable during processing?
A: It is stable in dry conditions and in acid systems, but it degrades in neutral or alkaline solutions and is sensitive to heat, light, oxygen and metal ions. Please discuss your process conditions with us so the correct grade, dosage and addition step can be confirmed.
Q: Can you supply customized specifications?
A: Yes. Assay, particle size, packaging and documentation can be discussed against your target specification, subject to production confirmation and order quantity.
