Overview

E262II - Sodium diacetate

Sodium diacetate (E262ii) is a dry, vinegar-like powder used to keep foods fresh and tangy. It helps stop mold and some bacteria, and also controls acidity. You’ll most often find it in breads, snacks, seasonings, and some meat products.

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

Is sodium diacetate gluten free?
Yes—sodium diacetate is inherently gluten-free; it's a purified salt of acetic acid and contains no wheat, barley, or rye.
Is sodium diacetate bad for you?
No—at permitted food-use levels it’s considered safe (GRAS in the U.S. and authorized in the EU). It can add some sodium and, in high concentrations, may irritate the mouth or stomach, but typical amounts in foods are small.
What is sodium diacetate in food?
A 1:1 complex of sodium acetate and acetic acid used as an acidity regulator, preservative, and flavoring that imparts a vinegar note. It helps inhibit molds and some bacteria to extend shelf life.
What is sodium diacetate made from?
It’s made by neutralizing acetic acid (from fermentation or synthetic sources) with sodium hydroxide or sodium carbonate to form sodium acetate, then combining it with additional acetic acid to make sodium diacetate.
What is sodium diacetate used for?
To control pH and microbial growth and to provide salt-and-vinegar flavor; it’s common in breads and tortillas (mold inhibitor), snack seasonings, sauces, and processed meats (Listeria control, often with lactate).
