What is the ideal humidity level for storing dry grains?

The ideal humidity level for storing dry grains is below 70% humidity because maintaining appropriate moisture levels is crucial for preserving the quality and safety of the grains. High humidity can lead to mold growth, spoilage, and pest infestations, which can render the grains unsafe for consumption and result in significant food waste.

Storing grains at a humidity level below 70% helps to keep them dry and extends their shelf life. This level prevents the development of conditions that encourage the growth of bacteria and fungi, thus ensuring that the grains maintain their nutritional value, flavor, and overall integrity.

In contrast, higher humidity levels, such as above 70% or 50%, create an environment conducive to the proliferation of harmful microorganisms, while a level below 30% could potentially dry out the grains too much, affecting their quality and texture. Thus, maintaining a humidity level below 70% is essential for optimal grain storage.
