What is E160a? (Food Additive Explained)
E160a is beta-carotene — the natural orange pigment found in carrots, sweet potatoes, and other orange vegetables. As a food additive, it's used to give products a yellow to orange colour and is also a source of vitamin A.
What is E160a?
Full name: Beta-Carotene
E160a is beta-carotene, a carotenoid pigment that occurs naturally in many fruits and vegetables — it's what makes carrots orange. As a food additive, it can be extracted from natural sources (carrots, palm oil, algae) or produced synthetically. The body converts beta-carotene into vitamin A (retinol), which is why it's sometimes called provitamin A. It has been used as a food colouring for decades.
What does E160a do in food?
E160a gives food a natural-looking yellow to orange colour. It's popular with manufacturers who want to colour products without using synthetic dyes — labels can say 'colour: beta-carotene' rather than listing an artificial colour number. It's also used to standardise the colour of products like butter and cheese, which naturally vary in shade depending on the season and what the cows ate.
Where is E160a found?
E160a is commonly found in:
- Butter and margarine
- Cheese and processed cheese
- Fruit juices and soft drinks
- Cakes, biscuits, and pastries
- Ice cream and dairy desserts
- Breakfast cereals
Is E160a bad for you?
E160a is considered safe by EFSA, the FDA, and food authorities globally. It's one of the least controversial food colourings because it's a natural compound that the body can use as vitamin A. EFSA has set an ADI of 5 mg/kg body weight per day for synthetic beta-carotene. There are no significant health concerns at normal dietary levels. High-dose supplements of beta-carotene have been linked to increased lung cancer risk in smokers, but this is not a concern at the levels found in food.
Why E160a matters for food choices
E160a is often used as a 'clean label' alternative to synthetic colours — manufacturers prefer it because it sounds natural and familiar. While beta-carotene itself is harmless, its presence still means a product has been artificially coloured. The question to ask is always the same: why does this food need colouring? Sometimes the answer is innocent (standardising butter colour), but other times it's about making a processed product look more natural than it is.
