Yes, garlic powder can be stored with silica gel packets. Silica gel helps absorb moisture, preventing clumping and extending the shelf life of the garlic powder.
Garlic powder, like many powdered spices, is hygroscopic, meaning it readily absorbs moisture from the air. This absorbed moisture can lead to clumping, caking, and a reduction in flavor potency. Silica gel is a desiccant, a substance that absorbs moisture. By placing silica gel packets in the container with your garlic powder, you create a drier environment. This helps to prevent the garlic powder from absorbing moisture, thus preserving its texture, flavor, and preventing it from becoming a solid, unusable mass. Ensure the silica gel packets are food-grade and properly sealed to prevent any contamination. The amount of silica gel needed depends on the size of the container and the humidity of your storage environment. A good rule of thumb is to use one or two small packets for a standard spice jar.
To maximize the effectiveness of silica gel, store your garlic powder in an airtight container in a cool, dark place. This minimizes exposure to moisture and light, further extending its shelf life and preserving its flavor.
