Store dried oregano in an airtight container, away from heat, light, and moisture, to preserve its flavor. A cool, dark pantry is ideal.
Dried oregano loses its flavor primarily due to oxidation and evaporation of its volatile oils. These oils are responsible for oregano's distinctive taste and aroma. To minimize flavor loss, follow these steps:
Choose the Right Container: Opt for an airtight container made of glass, metal, or a high-quality, food-grade plastic. Avoid containers with loose-fitting lids.
Minimize Exposure to Air: Each time you use the oregano, reseal the container immediately to prevent prolonged exposure to air.
Control Temperature: Store the oregano in a cool place. High temperatures accelerate the degradation of the volatile oils. Avoid storing it near the stove or oven.
Protect from Light: Light, especially sunlight, can also degrade the oregano's flavor compounds. A dark pantry or cupboard is the best location.
Avoid Moisture: Moisture can cause the oregano to clump and lose its flavor. Ensure the container is completely dry before adding the oregano, and avoid storing it in humid environments.
Consider Vacuum Sealing: For long-term storage, vacuum sealing can significantly extend the shelf life and flavor of dried oregano.
Don't sprinkle oregano directly from the container into a steaming pot. The moisture can enter the container and degrade the remaining oregano. Instead, measure out the desired amount into your hand or a separate spoon.
