E320 (butylated hydroxyanisole, BHA)

E320 is butylated hydroxyanisole, BHA. In food technology, this additive is used as an antioxidant: it helps slow down oxidation, rancidity of fats, darkening, loss of color, or deterioration of the product’s taste.

What is this additive

By nature, E320 is a synthetic antioxidant. Antioxidants can be substances that occur naturally in food, as well as specially isolated or synthesized technological components.

It is important not to confuse the antioxidant function in a product with the promise of benefits for the body. On the label, the word “antioxidant” primarily means protection of the product itself from oxidation, not an automatic healing effect.

Why it is used

The main mechanism of action: it slows down the oxidation of fats, aromas, and fat-soluble components. As a result, the product retains its color, smell, taste, stability of the fat phase, and appearance for a longer time.

In practice, E320 can be found in products such as fats, oils, snacks, dry mixes, chewing gum, confectionery, and products with a fat phase. The specific application depends on the type of product, fat content, oxygen exposure, packaging, and shelf life.

Nutritional value and metabolism

In technological doses, antioxidants are usually not a significant source of calories, proteins, fats, or carbohydrates. For glycemia, it is more important to look at the main composition of the product: sugar, starch, flour, syrups, fats, and portion size.

If an antioxidant is a form of vitamin, it does not always mean that the product can be considered a good source of that vitamin. Nutritional value depends on the dose, bioavailability, and the entire food matrix.

Safety and limitations

BHA is often discussed due to toxicological assessments and the acceptable daily intake; it is not a vitamin but a technological antioxidant.

Sensitive individuals may have an individual reaction to a specific product or group of additives, but more often the problem is related to the overall frequency of consumption of ultra-processed products, oxidized fats, excess sugar, and a deficiency of whole foods.

How to read the label

On the label, E320 may be indicated as an E number or by its name: butylated hydroxyanisole, BHA. It is better to evaluate it together with the function of the additive, the type of product, the quality of fats, shelf life, and overall diet, rather than by one E number alone.
