Pantry

1-3 months (opened)

Store in a cool, dark, dry place in an airtight container to prevent rancidity and absorption of odors. Keep away from heat and light.

Refrigerator

6 months

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

Freezer

1 year

Store in a heavy-duty freezer bag or airtight container. Freezing is excellent for long-term storage and helps maintain flavor and texture.

Signs of Spoilage

  • Sour, bitter, or paint-like smell (rancidity)
  • Mold growth (fuzzy spots, discoloration)
  • Shriveled or discolored appearance
  • Off-flavor or stale taste

Room Temperature Safety

The 2-hour rule applies: Do not leave perishable foods, including nuts that have been exposed to moisture or other contaminants, at room temperature for more than 2 hours. If the temperature is above 90°F (32°C), the limit is 1 hour.

The 'Danger Zone' for food is between 40°F (4°C) and 140°F (60°C), where bacteria can multiply rapidly.

While dry roasted cashews are less prone to rapid bacterial growth than high-moisture foods, prolonged exposure to room temperature, especially in humid conditions, can accelerate rancidity and mold growth. Always store in a cool, dry place or refrigerate/freeze for best quality and safety.

Expert Tips

Safe Handling

1

Always store cashews in airtight containers to protect them from moisture, air, and odors.

2

Check for signs of spoilage before consumption.

3

Toasting nuts can enhance their flavor but does not extend their shelf life significantly; proper storage is still crucial.
