Oseltamivir is a widely used medication for treating and preventing influenza, and star anise has been identified as a significant natural source of shikimic acid for its manufacturing. While star anise itself does not offer the same therapeutic benefits as oseltamivir, its shikimic acid content contributes to the global supply of this essential pharmaceutical ingredient.
How should star anise be stored to maintain its flavor and potency?
Proper storage is essential to preserve the flavor and potency of star anise. It is best stored in an airtight container in a cool, dark, and dry place, away from direct sunlight and heat. This helps to prevent the volatile oils, which contribute to its distinctive aroma and flavor, from evaporating or degrading.
When stored correctly, whole star anise pods can maintain their flavor for up to two to three years. Ground star anise, however, tends to lose its flavor more quickly and should ideally be used within six months for optimal taste. Checking for a strong, characteristic aroma upon opening the container is a good indicator of freshness.
