How long does gel food colouring last?

Gel food coloring can last for several years if stored properly, typically around 3-4 years. To maximize its shelf life, keep it in a cool, dark place and ensure the lid is tightly sealed. While it may remain safe to use beyond its expiration date, its potency and color intensity may diminish over time. Always check for any signs of spoilage, such as changes in texture or odor, before use.
