Overview

E301 - Sodium ascorbate

Sodium ascorbate (E301) is the sodium salt of vitamin C. Food makers use it mainly as an antioxidant and color helper, especially in cured meats. You might also see it in drinks and fruit products to keep flavors and colors fresh.

E335I - Monosodium tartrate

Monosodium tartrate (E335i) is a sodium salt of tartaric acid. It acts mainly as a sequestrant and stabiliser, helping foods keep their color, clarity, and taste during shelf life. It belongs to the same family as potassium and calcium tartrates found naturally in grapes and wine.

How to make sodium ascorbate?
It’s produced by neutralizing L-ascorbic acid with a sodium base (commonly sodium bicarbonate or sodium carbonate) and then drying; food-grade production is controlled for purity and is not recommended to replicate at home.
How to take sodium ascorbate?
Follow the product label, typically taken with water or food; don’t exceed about 2,000 mg/day of vitamin C from all sources unless advised, and account for the added sodium.
