Store in a cool, dry, dark place away from direct sunlight and heat. Keep tightly sealed in an airtight container after opening to prevent moisture absorption and pest infestation.

Refrigerator

Not typically required; can extend quality for opened mixes, especially those containing whole grains or nuts, for up to 6 months

Store in an airtight container to prevent moisture absorption and odors from other foods. Bring to room temperature before use for best results.

Freezer

Not typically required; can extend quality for opened mixes, especially those containing whole grains or nuts, for up to 1 year

Store in an airtight, freezer-safe container or heavy-duty freezer bag to prevent freezer burn and moisture. Bring to room temperature before use.

Signs of Spoilage

  • Presence of pests (e.g., weevils, beetles)
  • Mold growth (due to moisture exposure)
  • Off-odor (rancid smell if fats are present, or general staleness)
  • Discoloration
  • Hardening or clumping (due to moisture absorption)

Room Temperature Safety

The 2-hour rule and danger zone primarily apply to perishable foods. For dry mixes, the rule is to keep them dry and sealed to prevent moisture and pests.

Not applicable to dry, shelf-stable mixes in the same way as perishable foods.

Store dry mixes in a cool, dry place, ideally below 70°F (21°C), away from direct sunlight and heat sources to maintain quality and prevent pest infestation.
