Signs of Spoilage
- Mold growth (if exposed to moisture)
- Off-odor (musty or sour smell)
- Discoloration
- Presence of pests (e.g., weevils, beetles)
- Hard clumps that cannot be broken apart (due to significant moisture absorption)
Room Temperature Safety
The danger zone (40°F–140°F) applies to perishable foods. Dry potato starch, in its original form, is shelf-stable.
Store dry potato starch in a cool, dry place below 85°F (29°C) to maintain quality and prevent clumping or pest infestation. Keep away from moisture and direct sunlight.
Safe Handling
Keep potato starch dry at all times to prevent mold growth and clumping.
Store in an airtight container to protect from moisture, odors, and pests.
Use clean, dry utensils when scooping potato starch to avoid contamination.
