Yes, sun-drying whole pulses before storage is highly recommended. It reduces moisture content, preventing mold growth and insect infestations, thus extending their shelf life.
Sun-drying pulses is a traditional and effective method for preserving them. Pulses, like beans, lentils, and peas, naturally contain some moisture. This moisture can create a favorable environment for mold and insects to thrive during storage, leading to spoilage and loss of nutritional value.
The process involves spreading the pulses in a thin layer on a clean surface, such as a tarp or a large tray, and exposing them to direct sunlight for several days. The sun's heat evaporates the moisture from the pulses, reducing their water content to a level that inhibits microbial growth and insect activity.
Here's a step-by-step guide:
Clean the pulses: Remove any debris, stones, or damaged pulses.
Spread them out: Lay the pulses in a single, thin layer on a clean, dry surface.
Sun-dry: Expose the pulses to direct sunlight for 3-5 days, or until they are completely dry. Turn them over periodically to ensure even drying.
Check for dryness: The pulses should be hard and brittle when dry. You should not be able to easily dent them with your fingernail.
Store properly: Once dried, store the pulses in airtight containers in a cool, dry place.
Avoid drying pulses on concrete surfaces, as they can absorb moisture from the ground. Use a raised platform or a tarp to prevent this.
