E267 (buffered vinegar)

E267 is buffered vinegar. In food technology, this additive is used to control acidity, stability, structure, or chemical resistance of the product, depending on the specific salt or acid.

What is this additive

By nature, E267 is a new food additive based on vinegar with buffering agents. Many such substances have related forms: acid, sodium salt, potassium salt, calcium salt, or complexes with metals, which affects solubility, taste, and technological role.

It is important not to judge the additive solely by its number. Some substances in this group occur naturally in regular food, others are purely technological salts, and others mainly appear in old or reference lists.

Why it is used

The main function: it acts as a preservative and acidity regulator. It helps the manufacturer achieve a stable taste, desired pH, predictable texture, color protection, or better performance of other recipe components.

In practice, E267 may be found in products such as meat products, ready meals, sauces, and products where mild acidity and control of microbial growth are needed. Specific permitted categories depend on legislation, dosage, and the purpose of the additive in the recipe.

Nutrition and metabolism

In technological amounts, such additives are usually not a major source of calories or carbohydrates. For the metabolic effect of the product, sugar, starch, flour, fats, salt, alcohol, and overall portion size are often more important.

If the additive contains sodium, potassium, calcium, magnesium, or phosphorus, its mineral contribution depends on the dosage. In cases of kidney disease, sodium restriction, or phosphate control, such details may be more important than for a healthy person.

Safety and restrictions

E267 has been separately authorized in the EU as buffered vinegar; it should not be confused with regular vinegar in the ingredient list.

Tolerance depends on dose and context. Acids can irritate mucous membranes at high concentrations, phosphates are important in mineral metabolism disorders, and sequestrants and old reference positions should be evaluated particularly carefully.

How to read the label

E267 may be listed on the label as an E number or by name: buffered vinegar. It is better to look at the function of the additive, the product category, frequency of consumption, and the entire composition, rather than perceiving any acidity regulator as automatically harmful or beneficial.
