Storage Recommendations for Water-Soluble Coffee Flavor (Food Use)

For water-soluble coffee flavors used in food, refrigeration is generally not required and may even be counterproductive, especially if the flavor is in powder form.

The standard storage recommendation is to keep the flavor in a cool, dry place, away from direct sunlight and heat, in a tightly sealed container.

• Cool, Dry Place: This is the most important factor for maintaining the quality and shelf life of the flavor.
• Refrigeration (Caution): While a refrigerator is cool, the environment is often humid. If the container is not sealed perfectly, the powder flavor can absorb moisture from the air inside the refrigerator, leading to clumping, degradation, and potential loss of flavor intensity.

Therefore, storing it in a kitchen cabinet or pantry that is cool and dry is usually the best practice.
