Yes, chili flakes can be frozen to help preserve their spiciness and prevent them from becoming stale. Freezing slows down the degradation of capsaicin, the compound responsible for the heat.
Chili flakes, like other dried spices, can lose their potency over time due to exposure to air, light, and heat. Capsaicin, the active compound that gives chili flakes their spiciness, gradually degrades, resulting in a milder flavor. Freezing chili flakes significantly slows down this degradation process.
To freeze chili flakes effectively:
When you need to use the chili flakes, simply take out the desired amount and reseal the container immediately. There's no need to thaw them before using; you can add them directly to your cooking.
For optimal freshness, consider vacuum-sealing the chili flakes before freezing. This removes even more air and further extends their shelf life and spiciness.
