Soaked dals can be stored in the refrigerator to slow down fermentation, but they will eventually ferment. Proper storage and timely cooking are essential to prevent spoilage.
Soaking dals is a common practice to reduce cooking time and improve digestibility. However, soaking also activates enzymes and microorganisms that can lead to fermentation, especially at room temperature. Refrigeration significantly slows down this process, but it doesn't eliminate it entirely. Here's a breakdown:
Initial Soaking: When you soak dals, they absorb water, creating a favorable environment for microbial growth.
Refrigeration: Storing soaked dals in the refrigerator (around 4°C or 40°F) slows down the metabolic activity of these microorganisms, thus delaying fermentation.
Storage Time: Soaked dals can typically be stored in the refrigerator for up to 2-3 days without significant fermentation. Beyond this, you'll likely notice a sour smell or a change in texture, indicating spoilage.
Proper Storage: Ensure the soaked dals are submerged in water within an airtight container to minimize exposure to air and further inhibit microbial growth.
To further extend the storage life of soaked dals, change the water daily and rinse the dals thoroughly before refrigerating. This helps remove some of the microorganisms and slows down the fermentation process even more.
