Yes, green gram (mung bean) can be stored in powdered form, often called mung bean flour or besan. This extends its shelf life and makes it convenient for various culinary applications.
Storing green gram as a powder significantly increases its shelf life compared to storing it as whole beans. The reduced moisture content in the powdered form inhibits the growth of mold and bacteria, which are primary causes of spoilage. To create mung bean flour, the green gram beans are typically roasted lightly to enhance flavor and then ground into a fine powder using a grinder or mill. This powder can then be stored in an airtight container in a cool, dry place, away from direct sunlight. Proper storage is crucial to prevent the flour from clumping or absorbing moisture, which can lead to spoilage. Mung bean flour is versatile and can be used in various recipes, including pancakes, crepes, soups, and as a thickening agent.
To ensure the freshness of your mung bean flour, consider storing it in the refrigerator, especially in humid climates. This will further protect it from moisture and extend its shelf life even more.
