Signs of Spoilage
- Rancid or bitter taste
- Off-odor, often described as paint-like or chemical
- Mold growth
- Discoloration or shriveled appearance
- Soft or rubbery texture (should be firm and crisp)
Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).
While whole, unshelled nuts are less susceptible, shelled nuts can become rancid more quickly at room temperature. Always store in a cool, dry place or refrigerate/freeze for extended freshness.
Safe Handling
Always wash hands before and after handling nuts.
Store nuts in airtight containers to protect from moisture and pests.
If roasting at home, ensure proper cooling before storage.
Check for signs of spoilage before consumption.
