Does turmeric and cayenne expire

Turmeric and cayenne pepper do not have a strict expiration date, but they can lose potency and flavor over time. Typically, ground spices like these can last about 2-3 years if stored in a cool, dark place in an airtight container. While they may not spoil in the traditional sense, it's best to check for changes in color, aroma, or taste to determine if they're still effective for cooking. Always trust your senses when evaluating the freshness of spices.
