Food colouring is a staple in many kitchens, adding colourful shades to various dishes and treats. Whether or not it’s for a birthday cake or a batch of cookies, food colouring can increase the visual appeal of your culinary creations. However, like many elements, food colouring does have a shelf existence. In this blog, we will cover whether food colouring can go bad, what the symptoms of food colouring go bad, its lifespan, safety issues, opportunity uses, and storage pointers to prolong its usability.
Signs that Food Colouring has gone bad
1. Change in colour
Does the food colouring fade or become murky? This is a clear indication that the colouring has lost its effectiveness and may not give results as we expected.
2. Consistency
Has the liquid become thick and clumpy? This may indicate drying or possible contamination.
3. Mould
Always check for mould development, especially if the container has been left open for an extended period of time. Mould is a clear clue that the colour of the food is not efficient now.
4. Smell
It is probably unsafe to use food colouring if it smells foul or unpleasant.
What is the lifespan of food colouring?
Food colouring has an unexpectedly long shelf life! Unopened containers or bottles have a longer shelf life, however, exact expiration dates may vary depending on the type (liquid, gel, or powder). The typical lifespan of liquid food colours is 2 to 3 years, although gels and powders can last up to 7 years.
Is there any secret to longevity? Keep your food colouring products in a cool, dark cabinet. Heat and light can damage food colours, so keep them out of direct sunlight. A little fading is usually okay, even after that you should always check the expiration date. If the colour fades or becomes mouldy, it should be replaced.
Is it safe to use food colouring past the expiration date?
Generally, yes. Expiration dates on food colouring typically indicate a decline in quality, meaning the colours may not be as vibrant. As long as there are no signs of spoilage (like mould or an off-odour), it should still be safe to use.
How can I store food colouring to make it last longer?
Proper storage is essential for preserving the shelf life of food colour. Here are some tips to help preserve its quality.
1. Away from Direct Sunlight and Heat Sources
Store food colouring in a cool, dark cabinet out of direct sunlight and heat. Heat can speed up spoiling and cause colours to fade.
2. Seal Tightly
After each use, place the food colouring back in its original, airtight jar and make sure the lid is tight. This helps in preventing contamination and moisture loss, which can thicken the consistency.
3. Keep it in a cool
If you live in a warm region, consider refrigerating unsealed food colouring containers. Reduced temperature will aid in delaying any possible spoiling.
Are there other uses for expired food colouring, besides in food?
Even if your food colouring is beyond its prime for culinary applications, there are still lots of ways to use it:
1. Holi Celebrations
Expired food colouring may be used to create brilliant and colourful powders or water-based dyes during Holi, the festival of colours.
2. Rangoli Art
Use expired food colouring to make beautiful and intricate Rangoli patterns for occasions such as Diwali and Pongal.
3. Crafts & DIY Projects
Use expired food colouring to dye paper, cloth, and even clay for arts and crafts activities.
4. Educational Activities
Incorporate expired food colouring into science experiments or educational activities to teach principles such as colour mixing or chromatography in an engaging and participatory manner.
5. Natural Dyes
Food colouring may be used to colour non-food objects such as play dough, candles manufactured at home, and even environmentally friendly paints for crafts.

Conclusion
Food colour may lose its colour, texture, and flavour with time, even if it doesn’t always “go bad” in the conventional sense. You can make sure that your food colouring stays safe and effective for all of your culinary endeavours by keeping an eye out for symptoms of deterioration, knowing how long it lasts, and according to recommended storage procedures. Keep in mind that replacing outdated food colouring is always a better option than compromising the integrity of your food.
