Equilibrium Moisture Content Theory

Equilibrium Moisture Content (EMC) theory explains that materials like grains or wood absorb or lose moisture until reaching a balance with their environment, specifically the humidity and temperature. At this point, the material's moisture level stays steady because the rate of moisture absorption equals the rate of moisture loss. The EMC depends on the surrounding conditions: higher humidity increases moisture content, while lower humidity decreases it. Understanding EMC helps in controlling storage conditions to prevent damage like mold or decay, ensuring the material remains stable and in good condition.
