E230 (a biphenyl, diphenyl)

E230 is a biphenyl, diphenyl. In food technology, this additive is primarily considered a preservative: its task is to slow down spoilage, control the growth of undesirable microorganisms, or maintain product stability during storage.

What is this additive

By its nature, E230 is a preservative from older lists, mainly used for treating citrus fruits. For accuracy, it is important not to confuse it with neighboring E-codes: close numbers often denote salts of the same acid or substances of the same group, but this is not always the same.

Preservatives do not make a product “eternal” and do not fix poor raw materials. They only work within a specific technology: at the required acidity, humidity, temperature, dosage, and sanitary quality of production.

Why it is used

The main mechanism of action: it suppresses mold on the surface of fruits. That is why E230 is used not for taste or nutritional value, but for shelf life, safety, and predictable product quality.

In practice, E230 may be found in products such as surface treatment of citrus fruits and packaging materials in older practices. Specific permitted categories and levels depend on the legislation of the country and the type of product.

Nutrition and metabolism

In normal technological doses, preservatives are rarely a significant source of calories, proteins, fats, or carbohydrates. For blood glucose and insulin, the product itself is often more important: sugar, starch, flour, syrups, alcohol, salt, fats, and portion size.

However, frequent consumption of products with preservatives may be a marker of an ultra-processed diet. Therefore, the question is not only about one E-number, but about the overall structure of the diet: how many whole foods, proteins, fibers, minerals, and normal foods are in the diet.

Safety and limitations

E230 is not among the currently permitted food additives in the EU/GB; if it appears in reference books, it is important not to transfer old practices to modern labeling.

Individual tolerance varies. Sensitive individuals may have reactions to specific groups of preservatives, especially sulfites, benzoates, or nitrite-nitrate products; if a repeated reaction occurs, it is advisable to compare symptoms with the label and discuss it with a specialist.

How to read the label

On the label, E230 may be indicated as an E number or as a name: biphenyl, diphenyl. It is better to assess it together with the function of the additive, the product category, frequency of consumption, shelf life, and the complete composition, rather than making a conclusion solely based on the presence of the E-code.
