Answer Details
The best way to preserve maize grains on a large scale is by storing them in airtight containers or silos. This prevents moisture and insects from getting into the grains, which can cause spoilage or infestation. Storing maize grains under the sun or in soils may expose them to moisture and pests, while hanging them over fire places may expose them to smoke, which can affect the quality and safety of the grains. Earthen pots may not be suitable for large scale storage as they have limited capacity and may not be airtight. Airtight containers or silos can help to keep maize grains fresh and safe for a longer period of time, ensuring their availability and quality for consumption or sale.
