Sodium Erythorbate
Sodium Erythorbate is the sodium salt of D-isoascorbic acid (erythorbic acid), used industrially as the workhorse antioxidant and cure accelerator additive E316.
The molecule (CAS 6381-77-7, C₆H₇NaO₆·H₂O, molecular weight 216.12 g/mol as the monohydrate) is a white to slightly yellow crystalline powder, highly water-soluble (more than 16 g per 100 mL at 25 degrees Celsius) and with a near-neutral aqueous pH.
We source bulk Sodium Erythorbate from top China manufacturers for our partners, working with several of them. The manufacturers are in Jiangxi, Henan and Shandong. For this ingredient the minimum order is 500 kg and a 20-foot container takes 22 MT, and a smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Sodium Erythorbate is produced primarily in fine powder and granular grades.
Fine powder grades are standard for cured meat brines, where rapid and complete dissolution is essential before injection or tumbling.
Granular grades are used in dry rubs, dry seasoning blends, and direct addition to beverage premixes.
The standard commercial assay is not less than 98 percent on a dried basis, with most modern grades delivering 99 percent or higher.
FCC food-grade material is the standard supply. Most production today originates in China, with secondary supply from Japan and Europe. Each lot is qualified by assay, specific rotation, water content, heavy metals, and trace iron, the last because residual iron catalyses oxidative degradation during storage.
Applications
- Cured meat processing as a cure accelerator and colour fixative, the dominant application by volume
- Bacon, ham, frankfurters, sausages, and luncheon meats
- Smoked and cured fish products
- Cured poultry products including turkey breast and chicken roll
- Pickled vegetables and brined products as an oxidation inhibitor
- Bottled beverage oxygen scavenging in juices and sports drinks
- Frozen vegetable colour preservation
- Canned mushroom processing to prevent oxidative browning
- Salad dressings and mayonnaise as a fat-phase antioxidant adjunct
- Wine and beer bottling as an antioxidant alternative to ascorbic acid
- Industrial water treatment as an oxygen scavenger

How We Help Source Sodium Erythorbate
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Sodium Erythorbate out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Sodium Erythorbate together with other ingredients such as Ascorbyl Palmitate, Disodium EDTA and Erythorbic Acid into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Sodium Erythorbate is approved as a food additive globally.
In the European Union it carries the E number E316, permitted under Regulation (EC) 1333/2008 in defined cured meat, cured fish, and beverage categories.
The U.S. FDA lists it as GRAS under 21 CFR 182.3731 alongside sodium ascorbate, and USDA FSIS regulations specifically permit sodium erythorbate in cured meat at defined inclusion rates as a cure accelerator.
JECFA has reviewed the substance together with erythorbic acid and assigned a group ADI not specified.
The substance carries no vitamin C activity for human nutrition and must not be declared as vitamin C on food labels. Kosher, Halal, and non-GMO certifications are routinely available.
Manufacturing Process
Sodium Erythorbate is produced by neutralisation of D-isoascorbic acid (erythorbic acid) with sodium bicarbonate or sodium carbonate in cold aqueous solution under inert atmosphere.
The reaction releases carbon dioxide and yields a near-neutral solution of the sodium salt. The solution is filtered through a polishing filter, concentrated under vacuum, and crystallised by addition of ethanol or by controlled cooling.
Crystals are filtered, washed with cold ethanol, and dried under vacuum at temperatures below 60 degrees Celsius to preserve the monohydrate form and avoid oxidative discoloration.
The starting erythorbic acid is fermentation-derived from D-glucose in modern supply chains.
Each lot is verified by assay, water content (typically 8 to 9 percent as the monohydrate), specific rotation, heavy metals, and trace iron. Storage in airtight, light-protected containers is essential because the dissolved salt oxidises rapidly in the presence of air, moisture, and metal ions.
