How does light exposure affect dried herb quality?

Question

Discover how light degrades dried herbs and how to store them properly.

Answer 1

Light exposure degrades dried herbs by breaking down volatile oils, leading to a loss of flavor, aroma, and color. Store dried herbs in airtight, opaque containers in a cool, dark place to preserve their quality.

Detailed Explanation:

Dried herbs contain volatile oils that give them their characteristic flavor and aroma. These oils are sensitive to light, particularly ultraviolet (UV) light. When exposed to light, these oils undergo a process called photodegradation. This means the light energy breaks down the chemical bonds within the oil molecules, altering their structure and causing them to evaporate or transform into other compounds. As a result, the herb loses its potency, flavor becomes muted, and the vibrant color fades. The longer the exposure and the stronger the light, the more significant the degradation. Therefore, proper storage is crucial to protect dried herbs from light and maintain their quality over time.

Pro Tip:

To test if your dried herbs are still potent, crush a small amount in your hand. If the aroma is weak or non-existent, it's likely the herbs have lost their flavor due to light exposure or age and should be replaced.
