Room Temperature Safety
The danger zone (40°F–140°F) applies to perishable foods, including reconstituted lemon juice, not the dry powder.
Keep dry lemon juice powder in a cool, dry place. If reconstituted, treat as fresh lemon juice and refrigerate promptly after use, discarding if left at room temperature for more than 2 hours (1 hour above 90°F/32°C).
Safe Handling
Always use clean, dry utensils when scooping powder to prevent introducing moisture.
Ensure the container is tightly sealed after each use to protect from humidity and air.
If reconstituting, use clean water and treat the reconstituted liquid as fresh lemon juice, refrigerating promptly.
