E160b (annatto, bixin, and norbixin)

E160b is annatto, bixin, and norbixin. In the food industry, this additive is used as a colorant: it helps to give the product the desired shade, restore color after processing, or make the appearance more stable and recognizable.

What is this additive

By nature, E160b is an orange colorant derived from the seeds of Bixa orellana. It is important to distinguish the technological use of the colorant from the nutritional value of the product: the mere presence of a colorant does not indicate that the product is beneficial or harmful until the entire composition is understood.

For accurate labeling, not only the number but also the name of the substance matters. Similar E-codes may have close colors but completely different sources, chemical structures, and usage restrictions.

Why it is added

The main task of E160b is to provide an orange hue. Colorants are especially often used where the natural color of the raw material is lost due to heating, storage, grinding, mixing with other ingredients, or prolonged transportation.

In practice, E160b can be found in products such as cheeses, oils, dairy products, snacks, sauces, desserts, and confectionery. The specific application depends on the legislation of the country, the product category, dosage, and the technological purpose of the manufacturer.

Nutritional value and metabolism

Colorants are usually added in very small amounts, so they rarely represent a significant source of calories, proteins, fats, or digestible carbohydrates. For blood sugar and insulin, the product’s recipe is often more important: sugar, flour, starch, syrups, fats, and portion size.

If a product is marketed as dietary, low-carb, or for children, the presence of a colorant should still be evaluated alongside the other ingredients. A bright color can mask a poor composition but may also occur in a neutral technological dose.

Safety and possible restrictions

There is a second draft of E160b on the website with an erroneous description of beta-carotene; the correct identification for E160b is annatto, bixin, and norbixin.

Individual tolerance varies: sensitive individuals may have reactions to specific colorants or to the product as a whole. If itching, rash, headache, abdominal discomfort, or unusual reactions in a child occur after a specific meal, it is useful to correlate the symptoms with the composition and discuss it with a specialist.

How to read the label

On the label, E160b may be indicated as an E number or as a name: annatto, bixin, and norbixin. It is better to evaluate not just the number in isolation but the entire food matrix: frequency of consumption, amount of ultra-processed products, sugar, sweeteners, flavorings, preservatives, and overall diet.
