Pantry

Shelled: 1-2 months; Unshelled: 3-4 months

Store in a cool, dark, dry place in an airtight container to prevent rancidity and absorption of odors.

Refrigerator

Shelled: 4-6 months; Unshelled: 6-9 months

Store in an airtight container to prevent absorption of odors and extend freshness.

Freezer

1 year or longer

Store in a heavy-duty freezer bag or airtight container to prevent freezer burn and maintain quality.

Signs of Spoilage

  • Mold growth (fuzzy spots, discoloration)
  • Shriveled or dried-out appearance
  • Bitter, sour, or stale taste
  • Rancid or 'paint-like' odor

Room Temperature Safety

Perishable foods should not be left out at room temperature for more than 2 hours; 1 hour if the temperature is above 90°F (32°C). While dry peanuts are shelf-stable, this rule applies to prepared peanut dishes or if exposed to conditions promoting mold.

40°F–140°F (4°C–60°C)

For raw, dry peanuts, the primary concern at room temperature is rancidity and mold growth, not rapid bacterial proliferation. Store in a cool, dry place away from direct sunlight and heat to maintain quality and prevent spoilage.

Expert Tips

Safe Handling

1

Keep peanuts dry to prevent mold growth, especially aflatoxin.

2

Always store in airtight containers to protect from moisture, pests, and odors.

3

Check for signs of spoilage (mold, rancid odor) before consumption.
