Factors Affecting Sweet Corn’s Shelf Life
Temperature
Sweet corn prefers cool temperatures to extend its shelf life. Avoid storing it at room temperature for extended periods.
Humidity
High humidity promotes mold growth. Store sweet corn in a well-ventilated area or wrap it in a slightly damp paper towel to maintain optimal moisture levels.
Air Exposure
Exposure to air can dry out sweet corn. Keep it tightly wrapped in plastic wrap or an airtight container to minimize air contact.
Husk
The husk acts as a protective layer, preserving the corn’s moisture and sweetness. Keep the husk intact until ready to use.
Maturity
Sweet corn is at its peak flavor and nutritional value when harvested at the right maturity stage. Overripe corn will spoil faster.
