As a professional tomato paste manufacturer, we often receive the question:
“Does canned tomato paste go bad?”
The short answer is yes—but with proper processing and storage, canned tomato paste remains safe and high-quality for an extended period.
✅ What Is the Shelf Life of Canned Tomato Paste?
Canned tomato paste is a concentrated tomato product with low moisture and high solid content (typically 22%-24% Brix). It is heat-sterilized and vacuum-sealed in food-grade cans, providing a typical shelf life of 24 to 36 months under optimal storage conditions.
❗ What Can Cause Tomato Paste to Go Bad?
Despite its durability, the product can still degrade or spoil due to:
- Damaged or Rusted Cans – Allowing air or bacteria to enter.
- Improper Storage – High temperature or humidity accelerates deterioration.
- Expired Shelf Life – Product may change in color, flavor, or texture.
🔍 How to Tell If Tomato Paste Has Gone Bad
Before use, always check:
- Swollen, leaking, or bulging cans
- Foul, sour, or metallic smell
- Discoloration or visible mold
- Unusual taste after opening
If any of these signs are present, we recommend not using the product.
📦 Storage Tips for Best Quality
To maintain freshness and food safety:
- Store unopened cans in a cool, dry place (below 25°C / 77°F)
- After opening, refrigerate in a sealed container and use within 5–7 days
- For longer storage, freeze in small portions using airtight containers
