How long will tomatoes stay fresh in plastic bag?

The shelf life of tomatoes in a plastic bag can vary depending on several factors, including the type of tomato, the temperature, and the level of humidity. Here's a general guideline for how long tomatoes may stay fresh in a plastic bag:

1. Refrigerated: When stored in a refrigerator, tomatoes in a plastic bag can generally stay fresh for 3 to 5 days. Make sure the plastic bag is loosely sealed to allow for some air circulation.

2. Room Temperature: At room temperature, tomatoes in a plastic bag may last for 1 to 2 days. Avoid storing tomatoes at room temperature for extended periods, as they can quickly become overripe and spoil.

3. Factors Affecting Freshness:

- Type of Tomato: Some tomato varieties, such as cherry tomatoes or heirloom varieties, tend to have a shorter shelf life compared to larger, firmer tomatoes like Roma or Beefsteak tomatoes.

- Temperature: Tomatoes are sensitive to temperature fluctuations. Ideally, they should be stored at temperatures between 55°F (13°C) and 60°F (16°C). Storing tomatoes at higher temperatures can accelerate the ripening process and reduce their shelf life.

- Humidity: Tomatoes prefer slightly humid environments. Storing them in a plastic bag can help maintain some humidity, but it's important not to seal the bag too tightly, as this can lead to condensation and moisture buildup, which can promote spoilage.

To extend the freshness of tomatoes in a plastic bag:

- Choose firm, ripe tomatoes. Avoid tomatoes that are soft, bruised, or have cracks or blemishes.

- Store them separately. Don't store tomatoes with other fruits and vegetables that produce ethylene gas, such as apples, bananas, and melons, as this can accelerate ripening.

- Check them regularly. Inspect your tomatoes periodically and remove any that show signs of spoilage.

For longer storage, you can also consider preserving your tomatoes by canning, freezing, or drying them.
