Annatto (E160b): The European Regulatory Framework
Yes, annatto is extensively used in Europe, but its application is carefully managed under strict European Union food additive regulations. Annatto is officially identified by the E number E160b. This regulatory approach ensures its safety and establishes maximum permitted levels (MPLs) for different food categories. The process is overseen by the European Food Safety Authority (EFSA), which has conducted re-evaluations of annatto extracts to update safety data and permissible uses. For instance, a 2019 EFSA opinion evaluated new safety and exposure data, confirming its continued use in specific applications, leading to adjusted legislation. This contrasts with the US, where annatto is exempt from certification but its use is still regulated. This careful management reflects Europe's stringent approach to food safety and consumer protection, ensuring that annatto, while natural, is used responsibly.
A History of Coloring Cheeses and Beyond
Annatto's use in Europe is not a modern phenomenon; it dates back centuries. Historically, it was introduced to Europe by Spanish and Portuguese explorers who encountered its use in Latin American and Caribbean cuisines. In Europe, annatto found a particularly strong footing in the dairy industry, notably in England where it was used to standardize the color of cheeses like Red Leicester and Cheshire. Early use, dating as far back as the 16th century for Gloucester cheese, was to mimic the deep orange color of summer milk from grass-fed cows. This practice later spread to other cheeses and persists today. Cheeses like France's Mimolette and the Netherlands' Leyden also rely on annatto for their characteristic hues. Beyond cheese, annatto has a wide range of industrial applications, including coloring butter, margarine, and confectionery. Its versatility and natural origin make it a popular alternative to synthetic colorants.
Bixin and Norbixin: The Two Forms of Annatto
Annatto's two primary coloring compounds, bixin and norbixin, have different properties that dictate their applications. Bixin is oil-soluble and is extracted from the seed coating using oil or organic solvents. Norbixin is water-soluble and is produced when bixin is treated with an alkali. This difference in solubility is crucial for food manufacturers. The oil-soluble bixin is ideal for fat-based products like butter, margarine, and some cheeses, ensuring the color is evenly dispersed. In contrast, the water-soluble norbixin is used in water-based products such as ice cream, bakery products, and some dairy desserts. The EU legislation acknowledges and regulates both forms, ensuring they adhere to the same safety standards.
Applications in European Food Products
Annatto's use in Europe extends far beyond dairy products. Modern regulations, following revised evaluations by EFSA, have expanded its permissible uses. It is a versatile coloring agent that can produce shades of yellow, orange, and even red.
Common European food products using annatto include:
- Dairy Products: Ripened and processed cheeses, butter, and edible ices.
- Confectionery: Various candies and baked goods.
- Baked Goods: Fine bakery wares and certain breadcrumbs.
- Fats and Oils: Margarines and cooking oils.
- Fish Products: Smoked fish, like kippers.
- Soups and Sauces: To enhance color and consistency.

Conclusion: A Naturally Sourced Staple
In conclusion, annatto is undoubtedly used in Europe and holds a significant place in the food industry. Its status as food additive E160b is firmly established within the EU's regulatory framework, which ensures its safety and proper application across a wide range of products. From its historical role in coloring traditional European cheeses to its modern use in confectionery, dairy, and bakery items, annatto provides a versatile and naturally sourced yellow to orange hue. European manufacturers continue to rely on annatto, managed through rigorous oversight by bodies like EFSA, to meet consumer expectations for appearance and quality. The availability of both oil-soluble bixin and water-soluble norbixin further enhances its utility, making it a natural coloring staple for diverse food applications across the continent.

Annatto-Colored European Cheeses
Historically and presently, a number of European cheeses owe their distinctive hue to annatto, a tradition that predates modern regulations and continues today.
- Red Leicester (UK): One of the most famous examples, known for its vibrant orange color.
- Cheshire (UK): The colored varieties of this crumbly cheese use annatto.
- Double Gloucester (UK): Annatto was historically used to standardize its appearance.
- Mimolette (France): This hard cheese gets its bright orange rind from annatto.
- Leyden (Netherlands): A Dutch cheese that uses annatto for color.
- Shropshire Blue (UK): Although a blue cheese, some preparations use annatto to give the outer part an orange hue.
