Overview

E262I - Sodium acetate

Sodium acetate (E262i) is a salt of acetic acid. It is widely used in foods to control acidity, help preserve freshness, and add a mild “salt and vinegar” taste. It appears naturally in small amounts during fermentation, and is also made for food use.

E267 - Buffered vinegar

Buffered vinegar (E267) is vinegar that has been partially neutralized to make it less sharp while keeping its preserving power. It is used to control acidity and help keep foods safe from spoilage organisms, often as a “clean label” option in place of traditional preservatives. It tastes milder than straight vinegar yet still supports freshness and shelf life.

Popular questions

How to make sodium acetate?
Industrial food-grade sodium acetate is produced by neutralizing acetic acid with a sodium base (such as sodium carbonate/bicarbonate or sodium hydroxide), then crystallizing—often as the trihydrate—and drying as needed.
Is sodium acetate dangerous?
No—at permitted food-use levels it's considered safe (e.g., GRAS in the U.S.; ADI not specified by EFSA); concentrated material can irritate eyes/skin and large intakes add sodium to the diet.
What is sodium acetate used for?
In foods it acts as a preservative and acidity regulator, helping inhibit spoilage/pathogen growth (commonly in meats, snacks, and bakery) and also functions as a sequestrant; it can contribute a mild salt-and-vinegar flavor.
Is sodium acetate soluble in water?
Yes—sodium acetate (both anhydrous and trihydrate) is highly soluble in water and is deliquescent.
What is sodium acetate trihydrate?
It’s the hydrated form of sodium acetate (NaC2H3O2·3H2O), a stable crystalline grade that dissolves readily and is widely used in the same food applications as the anhydrous form to supply acetate.
