Chopped tomatoes typically last for 3-4 days in the refrigerator when stored properly in an airtight container.
The shelf life of chopped tomatoes depends on several factors, including their freshness when chopped, how they are stored, and the temperature of your refrigerator. Once a tomato is cut, its flesh is exposed to air and bacteria, which accelerates spoilage. To maximize their lifespan, follow these steps:
Start with Fresh Tomatoes: Choose firm, ripe tomatoes without blemishes or soft spots. The fresher the tomato, the longer it will last after chopping.
Chop Properly: Use a clean knife and cutting board to minimize contamination. Chop the tomatoes into your desired size.
Store in an Airtight Container: Place the chopped tomatoes in an airtight container. This helps to prevent them from drying out and absorbing odors from other foods in the refrigerator.
Refrigerate Promptly: Store the container in the refrigerator as soon as possible after chopping. The ideal refrigerator temperature is below 40°F (4°C).
Check for Spoilage: Before using, check the chopped tomatoes for signs of spoilage, such as a sour smell, slimy texture, or mold growth. If any of these are present, discard the tomatoes.
To extend the life of chopped tomatoes even further, consider adding a tablespoon of lemon juice or vinegar to the container before refrigerating. The acidity can help inhibit bacterial growth and keep them fresher for a slightly longer period.
