The ideal temperature for long-term pulse storage is below 15°C (59°F) to minimize insect activity and maintain quality. Lower temperatures are even better for extended storage.
Storing pulses properly is crucial for preserving their nutritional value, flavor, and preventing spoilage. Temperature plays a significant role in this. High temperatures accelerate the rate of insect infestation and the development of rancidity in the pulses' natural oils. Storing pulses below 15°C (59°F) significantly slows down these processes. Ideally, a cool, dry, and dark environment is best. This minimizes moisture absorption, which can lead to mold growth, and protects the pulses from light, which can degrade their quality. For very long-term storage (over a year), consider storing pulses in airtight containers in a refrigerator or freezer. This will further extend their shelf life and maintain their quality.
Before storing pulses, inspect them carefully for any signs of insect infestation. You can also freeze them for a few days to kill any potential pests before transferring them to long-term storage. This preventative measure can save you from a pantry full of infested pulses later on.
