Canned tomatoes, being a high-acid food, generally maintain their best quality for 18 months after the "use by" or "sell by" date printed on the can.
Here's a more detailed explanation:
Understanding "Best By" Dates on Canned Goods
- Not an Expiration Date: The "best by" or "use by" date on a can is not an expiration date, but rather a suggestion from the manufacturer regarding peak quality.
- Safety vs. Quality: Canned foods are generally safe to eat well beyond this date, provided the can is not damaged (e.g., bulging, rusted, dented). The main concern after the "best by" date is a potential decline in flavor, texture, or nutritional value.
- High-Acid Foods: Foods like tomatoes, which have high acidity, tend to be more shelf-stable.
Shelf Life of Canned Tomatoes
| Factor | Details |
|---|---|
| General Shelf Life | Canned foods can last many years past the "best by" date if stored properly. |
| Tomatoes (High-Acid) | Maintain peak quality up to 18 months after the "use by" or "sell by" date. |
Practical Tips for Canned Tomato Storage
- Storage Conditions: Store canned tomatoes in a cool, dry place away from direct sunlight and extreme temperatures.
- Inspect the Can: Before using, check for any signs of damage to the can, such as bulging, rust, or dents. Discard any damaged cans.
- Taste and Smell: If the can is intact but past the "best by" date, check the contents for any off odors or unusual tastes before consuming.
Key Takeaway
Bryan Quoc Le, Ph. D., a food scientist, states that high-acid canned foods such as tomatoes will maintain their quality for about 18 months after the "use by" or "sell by" date. While safe to consume beyond this period if stored correctly, the quality might diminish.
