Artificial colours aren’t just found in flashy treats - they can turn up in some of the most ordinary foods on your table. From breakfast favourites to cupboard staples, these hidden additives might surprise you. Once you know where they’re hiding, you’ll see everyday products in a whole new light.
This article is for general information and enjoyment only. Ingredients, colouring agents, and food labelling may vary by brand, product, and region. Always check packaging if you have dietary concerns or allergies.
1. Cheddar Cheese
Not all cheddar comes in that familiar orange colour. Traditionally, cheddar is naturally pale yellow to white, and many producers add annatto, a natural dye from the achiote seed, to achieve a consistent orange shade. It doesn’t affect the flavour, only the look.
This practice has been common for centuries and is still widely used today.
2. Breakfast Cereals
Those rainbow-coloured loops and fruity pebbles get their eye-catching hues from artificial dyes like Red 40 and Yellow 5. Many cereals marketed to children contain the highest amounts.
Manufacturers know bright colours attract young eaters, even though natural alternatives exist. Check ingredient lists for terms like "artificial colour" or specific dye names.
3. Canned Peas
Fresh peas often lose their bright green colour during the canning process. To keep them looking appealing, some manufacturers add permitted food colourings such as tartrazine or brilliant blue.
This is not the case for every brand, but it does happen in processed peas sold in tins. Always check the label if you want to avoid added colouring.
4. Sweets And Gummies
Jellybeans, gummy bears, and hard sweets rely heavily on artificial colours for their rainbow appeal. A single packet might contain six different synthetic dyes!
The vibrant blues, purples and greens rarely occur naturally in foods. Next time you enjoy these treats, notice how the brightest ones typically contain the longest list of artificial ingredients.
5. Flavoured Yogurts
Strawberry yogurt should get its pink colour from actual strawberries, right? Unfortunately, many brands use Red 40 instead of sufficient real fruit.
The fruit pictured on packaging often suggests more natural content than what's inside. Plain yogurts with fresh fruit added at home offer a dye-free alternative with genuine flavour and colour.
6. Soft Drinks
Ever wonder why that orange soda glows so brightly? Artificial colours like Yellow 6 and Red 40 create those unnaturally vibrant hues in fizzy drinks.
Mountain Dew contains Yellow 5, while many cola brands use caramel colouring. Even clear lemon-lime sodas sometimes include artificial colours to create a consistent appearance batch after batch.
7. Mustard
That vivid yellow in mustard comes mainly from turmeric, but some commercial mustards use added colourings to intensify the shade. Ingredients like tartrazine (Yellow 5) may be listed on certain labels. Not every brand includes artificial dye, so the colour can vary from one product to another.
The brightness you see often depends on whether it’s just turmeric or turmeric plus added colour.
8. Snack Chips
Those cheese-flavoured crisps rarely get their orange hue from actual cheese. Yellow 5 and Yellow 6 typically create that bright orange coating on your fingertips.
Many barbecue varieties use Red 40 for their reddish-brown appearance. The more vivid and consistent the colour across every chip, the more likely artificial dyes are responsible.
9. Packaged Baked Goods
Factory-made cakes, biscuits and pastries often contain hidden artificial colours. Those rainbow sprinkles on cupcakes? They're essentially pure sugar and synthetic dyes.
Red velvet cake traditionally used beetroot for colour, but modern versions typically rely on Red 40. Even seemingly plain baked goods might contain dyes to enhance their golden-brown appearance.
10. Sauces And Salad Dressings
That vivid orange French dressing never came from natural ingredients. Many commercial sauces use artificial colours to meet consumer expectations about how foods should look.
Barbecue sauce often contains caramel colouring, while salad dressings might include Yellow 5 or Red 40. Even white sauces sometimes contain titanium dioxide to appear more brilliantly white.
11. Ice Creams And Popsicles
Mint chocolate chip ice cream gets its green colour from Blue 1 and Yellow 5, not from mint leaves. Those rocket lollies with patriotic stripes? Packed with artificial dyes.
Children's character-themed frozen treats typically contain the most synthetic colours. Look for naturally-coloured alternatives using fruit purees, vegetable juices, or spices like turmeric for yellow hues.
