Expiration & Storage Tips
When does red food coloring expire?
Red food coloring is a long-lasting product. An unopened bottle can easily last up to 4-5 years from the manufacturing date. Once opened, it should be used within 2 years for optimal color performance, even though it doesn't technically expire or become unsafe to eat. Its shelf life depends largely on storage conditions. Freezing it is not advisable since it does not significantly extend the product life and can lead to changes in consistency.
How do you tell if red food coloring is bad?
To confirm if your red food coloring is past its prime, you can check for a few signs. The coloring should be liquid and free-flowing. If it looks clumpy, gel-like, or has crystallized, it's a good indication the food coloring has expired. Changes in color - a less vibrant or different shade of red - can also suggest staleness. Discoloration or a foul odor can't be ignored as well. Although it's rare since the product is technically non-perishable, it might grow mold if there was any chance of cross-contamination
Tips for storing red food coloring to extend shelf life
• Always store the red food coloring in a cool, dark place, away from direct sunlight or heat sources.
• After each use, ensure the bottle cap is sealed properly to prevent air exposure and contamination.
• Consider marking the opening date on the bottle. This will help remind you when it should be ideally used by.
• Use clean and dry utensils to drop or mix the coloring to avoid introducing moisture or contaminants into the bottle.
