Storing rice near moisture sources can lead to mold growth, pest infestations, and a decrease in the rice's overall quality and shelf life. This is because rice readily absorbs moisture from the surrounding environment.
Rice is hygroscopic, meaning it easily absorbs moisture from the air. When stored in humid environments or near sources of moisture like leaky pipes, sinks, or damp walls, the rice grains will absorb this moisture. This increased moisture content creates a favorable environment for mold and bacteria to grow, leading to spoilage. Moldy rice is not safe to consume and should be discarded. Furthermore, moist rice attracts pests like weevils and other insects, which can infest the rice and make it unusable. Finally, excessive moisture can alter the texture and flavor of the rice, making it mushy or stale even before cooking. Proper storage in a cool, dry place is crucial to maintain the quality and extend the shelf life of rice.
Store rice in an airtight container with a tight-fitting lid. Consider adding a desiccant packet (like those found in vitamin bottles) to absorb any residual moisture and further protect the rice.
