- Slime: A slimy texture or residue on the corn is a sign of bacterial contamination.
- Off-Odor: A sour or putrid odor is a clear indication of spoilage.
- Discoloration: Browning or yellowing of the kernels can indicate deterioration.
Tips for Preserving Sweet Corn
- Store in a Cool, Dark Place: Keep sweet corn away from direct sunlight and heat sources to prevent spoilage.
- Keep Husk Intact: For unhusked corn, leave the husk on until ready to cook or eat.
- Refrigerate Promptly: Refrigerate sweet corn as soon as possible after harvesting or purchasing.
- Use Airtight Containers: Store cooked sweet corn in airtight containers to prevent drying out and contamination.
Shelf Life of Canned and Frozen Sweet Corn
