Yes, garlic powder should be double-packed during the monsoon season to protect it from moisture and prevent clumping.
Garlic powder is highly hygroscopic, meaning it readily absorbs moisture from the air. During the monsoon season, humidity levels are significantly elevated, which can cause garlic powder to clump together, lose its flavor, and even spoil. Double-packing provides an extra layer of protection against moisture penetration. The first layer, typically the original packaging (a jar or bag), should be tightly sealed. Then, place this sealed package inside another airtight container, such as a resealable plastic bag or a container with a tight-fitting lid. This double barrier significantly reduces the risk of moisture reaching the garlic powder, preserving its quality and extending its shelf life. Consider adding a desiccant packet (silica gel) inside the outer container for even better moisture control.
Even with double-packing, store your garlic powder in a cool, dark, and dry place, away from direct sunlight and heat sources. A pantry or cupboard away from the stove is ideal. Avoid storing it near sources of moisture like the sink or dishwasher.
