Does grandulated onion powder go bad?

Granulated onion powder does not spoil in the traditional sense but can lose its flavor and potency over time. If stored in a cool, dry place and kept in an airtight container, it can last for several years. However, it's best to check for changes in smell, color, or clumping, which can indicate diminished quality. For optimal taste, use it within 2-3 years.
