How can moisture affect stored grain?

Moisture can significantly impact stored grain by condensing and leading to the formation of moldy areas. When grain is stored, maintaining the right moisture level is crucial. High moisture content can create conditions that favor the growth of mold and fungi. This happens because moisture acts as a catalyst for microbial activity, allowing molds and other fungi to thrive. As condensation develops in the storage environment—especially if temperature fluctuations occur—moisture can accumulate on the grain surface or within the storage facilities, promoting mold growth.

This is important to consider because moldy grain can result in both quality degradation and economic loss, affecting not only the grain's usability but also leading to potential health risks for consumers. Managing moisture levels is a critical aspect of grain storage practices to prevent these issues.
