Pantry

1-2 months

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

Refrigerator

3-6 months

Store in an airtight container or heavy-duty plastic bag to protect from moisture and odors. Refrigeration extends shelf life significantly.

Freezer

1 year or longer

Store in a heavy-duty freezer bag or airtight container. Freezing is ideal for long-term storage and helps prevent rancidity.

Signs of Spoilage

  • Rancid or bitter odor (often described as paint-like or chemical)
  • Mold growth (fuzzy spots, discoloration)
  • Significant discoloration or darkening
  • Shriveled or excessively dry appearance
  • Unpleasant or off taste

Room Temperature Safety

Perishable foods should not be left out at room temperature for more than 2 hours. If the temperature is above 90°F (32°C), food should not be left out for more than 1 hour.

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

While dried seeds are less prone to rapid bacterial growth than high-moisture foods, prolonged exposure to warm temperatures can accelerate rancidity and mold growth. For optimal quality and safety, store properly.

Expert Tips

Safe Handling

1

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

2

Check for signs of rancidity before consumption, especially if stored for extended periods.

3

Keep away from direct sunlight and heat sources, which can accelerate spoilage.
