No, urad flour and besan should not be stored together in the same container. Their different moisture contents and compositions can lead to spoilage and affect the flavor of both flours.
Urad flour, also known as black gram flour, and besan, or chickpea flour, have distinct characteristics. Urad flour tends to have a higher moisture content and a stronger aroma compared to besan. Storing them together can lead to the urad flour transferring its moisture and aroma to the besan, potentially causing the besan to become clumpy or develop an undesirable flavor. Furthermore, cross-contamination can occur, affecting the shelf life and quality of both flours. It's best to store each flour in an airtight container separately, in a cool, dry place away from direct sunlight. This will help maintain their individual qualities and prevent spoilage.
To extend the shelf life of your flours, consider storing them in the refrigerator, especially in warmer climates. This helps to prevent the development of rancidity and keeps them fresher for longer.
