Yes, dry roasted besan (gram flour) can be stored in bulk, but proper storage is crucial to maintain its quality and prevent it from going rancid or attracting pests. Store it in an airtight container in a cool, dark, and dry place.
Dry roasting besan enhances its flavor and extends its shelf life by reducing moisture content. However, the natural oils present in the flour can still oxidize over time, leading to rancidity. To store dry roasted besan in bulk effectively, follow these steps:
Cool Completely: Ensure the besan is completely cooled after roasting before storing it. Warm besan can create condensation inside the container, promoting mold growth.
Airtight Container: Transfer the cooled besan to an airtight container. Glass or food-grade plastic containers with tight-fitting lids are ideal. Avoid containers that allow air or moisture to penetrate.
Cool, Dark, and Dry Place: Store the container in a cool, dark, and dry place, away from direct sunlight, heat sources (like the stove or oven), and moisture. A pantry or cupboard is usually a good option.
Check Regularly: Periodically check the besan for any signs of spoilage, such as a musty odor, discoloration, or the presence of pests. If you notice any of these signs, discard the besan.
Consider Refrigeration/Freezing: For longer storage, especially in warmer climates, consider storing the besan in the refrigerator or freezer. This will further slow down oxidation and prevent spoilage. If freezing, ensure the container is freezer-safe.
Add a bay leaf or a few dried red chilies to the container. These natural ingredients can help repel pests and absorb any residual moisture, further extending the shelf life of your dry roasted besan.
