Room Temperature Safety
Not applicable to dry, shelf-stable ingredients. The danger zone (40°F–140°F) applies to perishable foods.
Keep in a cool, dry place away from direct sunlight and moisture to maintain quality and prevent spoilage.
Safe Handling
Always use clean, dry utensils when scooping potato starch to prevent introducing moisture.
Ensure the container is tightly sealed after each use to maintain dryness and prevent contamination.
Store away from strong odors, as dry starches can absorb them.
