Expiration & Storage Tips
When does blue food coloring expire?
Blue food coloring, like other artificial colorings, can last a long time when stored correctly. Sealed bottles can be used safely for 3 to 5 years, with no noticeable degradation in coloring quality. Even after it's been opened, blue food coloring can last up to 2 years if it's properly stored. It doesn't freeze well, so it's better to store it in the pantry rather than the freezer. The date on the package is more of a best-by rather than an expiry date. Nevertheless, if you notice any changes in quality, it might be time to replace the food coloring.
How do you tell if blue food coloring is bad?
Blue food coloring, when gone bad, may show changes in appearance and consistency. It might fade, darken, or develop a cloudy or chunky consistency. An off-odor, although uncommon, might also be an indicator. Blue color turning to a green or purplish hue can also be a sign of degradation.
Tips for storing blue food coloring to extend shelf life
• Keep the blue food coloring in a cool, dry place away from direct sunlight.
• Ensure the cap is tightly sealed after every use to prevent air exposure.
• Avoid storing near strong-smelling foods as food coloring can absorb those odors over time.
• It not recommended to refrigerate the blue food coloring as it can alter its consistency and effectiveness.
