Is Sodium Erythorbate (E318) Halal?

MUIS lists E318 (Sodium Erythorbate / Sodium Iso-Ascorbate) as doubtful (mashbooh), which means the source cannot be confirmed from the E-number alone — not that it is haram. It is produced by fermentation, and the fermentation medium, nutrients and processing aids vary by manufacturer and can include animal-derived ingredients. The additive itself is not haram; its status depends on how the producer makes it. The reliable check is a recognised halal certification logo on the finished product, or a manufacturer statement of the source.

Sodium erythorbate is the sodium salt of erythorbic acid, used as an antioxidant in cured meats. It accelerates the curing process and stabilises colour.

• Look for a recognised halal certification logo (MUIS, JAKIM, MUI, HMC or similar) on the packaging — certified products have had the source of this additive verified.
• Check whether the label states the origin, for example 'vegetable origin', 'plant-based' or 'soy'.
• If there is no certification and the origin is not stated, contact the manufacturer or choose a product with a halal alternative.
