What is Sodium Erythorbate CAS 6381-77-7?

It is a food-grade antioxidant and reducing agent derived from isoascorbic acid. Sodium Erythorbate is supplied as a white to slightly yellow crystalline powder with the molecular formula C6H7NaO6 and molecular weight 198.11 g/mol.

Is Sodium Erythorbate the same as sodium isoascorbate or E316?

Yes. Sodium Erythorbate is also called sodium isoascorbate and is assigned E number E316 for food use. These names refer to the same antioxidant ingredient identified by CAS 6381-77-7.

What does Sodium Erythorbate do in processed meat?

It acts as an oxygen scavenger and accelerates the color-fixing reaction of nitrite in cured meat systems. This helps maintain a stable cured color, reduce oxidative rancidity, and extend shelf life in products such as sausages, bacon, ham, and deli meats.

What are the main food applications of Sodium Erythorbate?

It is used in processed meat and poultry, beverages, fruit juices, canned foods, and frozen seafood. In these applications it controls oxidation, protects flavor and color, and helps reduce browning or spoilage during storage and distribution.

What grade and purity is Sodium Erythorbate normally supplied in?

It is commonly supplied as food grade with purity around 98.0-100.5% or higher. Commercial material may be produced to FCC or BP specifications for regulated food processing applications.

How should Sodium Erythorbate be stored and handled?

Store it in tightly closed containers in a cool, dry, well-ventilated area away from strong light and heat. Because the powder is sensitive to air and moisture, handling should minimize prolonged exposure and keep packaging intact to preserve quality and flowability.
