What is E150a? (Food Additive Explained)
E150a is plain caramel — the simplest form of caramel colour, made by heating sugar. It's one of the most widely used food colourings in the world, giving brown colour to cola, soy sauce, gravy, bread, and hundreds of other products.
What is E150a?
Full name: Plain Caramel
E150a is the plainest of the four caramel colour classes (E150a through E150d). It's produced by heating carbohydrates (sugars) with or without acids or alkalis — essentially the same process as making caramel at home, but on an industrial scale. Unlike the other caramel colours (E150b, c, d), E150a is made without ammonia or sulphite compounds, which makes it the least controversial of the group.
What does E150a do in food?
E150a is used purely as a brown colouring agent. It gives food and drinks a warm brown appearance — from light golden to deep dark brown. It doesn't significantly affect flavour at the concentrations used. It's incredibly common because brown is the expected colour of so many foods and beverages: cola, soy sauce, gravy, biscuits, and bread.
Where is E150a found?
E150a is commonly found in:
- Cola and dark soft drinks
- Soy sauce and Worcestershire sauce
- Gravy, stock, and brown sauces
- Bread, biscuits, and baked goods
- Whisky, brandy, and dark spirits
- Vinegar and pickles
Is E150a bad for you?
E150a (plain caramel) is generally regarded as the safest of the four caramel colours. EFSA considers it safe and has not set a specific ADI for it separately from the group. Unlike E150c and E150d (which are made using ammonia and have faced scrutiny over a by-product called 4-MEI), E150a is produced through simple sugar heating. It has no known adverse health effects at normal dietary levels.
Why E150a matters for food choices
E150a is interesting because it's so ubiquitous that most people don't even notice it. It's one of the most consumed food additives globally, yet it's rarely discussed. While plain caramel itself is harmless, its presence in a product is still a sign of manufacturing — the food has been coloured to meet consumer expectations of what it should look like. In NOVA terms, the presence of added colours, even natural ones, can contribute to a product's classification as processed or ultra-processed.
