5. Trust Your Nose: The Smell Test
Fresh canned tomatoes should smell bright, slightly tangy, and unmistakably tomato-like.
⚠️ Do not consume if you detect:
Sour or vinegary notes (possible lactic acid bacteria)
Yeasty, beer-like, or alcoholic odors (yeast fermentation)
Rotten, putrid, or “off” smells
When in doubt, throw it out. Never taste to “check.”
6. Watch for Texture and Color Changes
Spoiled tomatoes often show visible degradation:
Slimy or mushy texture
Dull, brownish, or grayish color
Separation that doesn’t recombine when stirred
These changes result from enzymatic breakdown or bacterial action—and mean the product is no longer safe.
