Pantry
Not RecommendedNot recommended once opened
Unopened cans/jars can be stored in a cool, dark pantry for up to 1 year or until the 'best by' date. Once opened, transfer to an airtight container and refrigerate immediately.
Refrigerator
5-7 days
Transfer opened tomato paste to a clean, airtight container. Do not store in the original can.
Freezer
3-4 months
For best quality, freeze opened tomato paste in small portions (e.g., in ice cube trays) then transfer to a freezer-safe bag or container. Thaw in the refrigerator.
Signs of Spoilage
- Mold growth on the surface
- Off-odor (sour, yeasty, or fermented smell)
- Discoloration (darkening or unusual color changes)
- Fuzzy or slimy texture
Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).
Always refrigerate opened tomato paste promptly. Discard any tomato paste that has been left in the danger zone for too long.
Safe Handling
Always use clean utensils when scooping tomato paste to prevent contamination.
Refrigerate promptly after opening to slow bacterial growth.
Do not consume if left at room temperature for more than 2 hours (1 hour if above 90°F/32°C).
