Pantry

6-12 months (unopened)

Store unopened packages in a cool, dark, dry place away from direct sunlight and heat. Once opened, refrigeration is highly recommended to prevent rancidity.

Refrigerator

Up to 1 year (opened)

Store in an airtight container in the refrigerator to protect from moisture and odors, and to significantly slow down the rancidity of the oils.

Freezer

1-2 years

Store in a heavy-duty freezer bag or airtight container to prevent freezer burn and absorption of odors. Thaw in the refrigerator before use.

Signs of Spoilage

  • Rancid or bitter smell/taste
  • Visible mold
  • Significant discoloration or darkening
  • Unusual stickiness or clumping

Room Temperature Safety

The 2-hour rule applies to perishable foods. While dry seeds are less prone to bacterial growth, their quality (especially oil content) degrades quickly at room temperature once opened.

40°F–140°F (4°C–60°C)

Hemp seeds, particularly shelled varieties, contain delicate oils that can become rancid when exposed to air, light, and heat. For best quality and to prevent rancidity, store opened packages in the refrigerator or freezer. Do not leave at room temperature for extended periods once opened.

Expert Tips

Safe Handling

1

Keep dry to prevent mold growth.

2

Store in airtight containers to prevent absorption of odors and moisture.

3

Check for signs of rancidity (bitter taste, off-smell) before use, especially if stored for extended periods.

4

Minimize exposure to air, light, and heat to preserve quality and prevent rancidity.
