With just these 3 preservation methods, you'll have tomatoes to use all year round.

How to preserve tomatoes using a vacuum sealer.

Vacuum sealing is a great help in food preservation, and tomatoes are no exception. This method inhibits oxidation, keeping tomatoes fresh and juicy for longer than with conventional storage methods.

Materials and tools: Ripe tomatoes. Vacuum sealer. Specialized vacuum sealing bags. Clean towel.

How to do it: First, wash the tomatoes thoroughly and let them drain. You can keep them whole or chop them up depending on your needs. If chopping them, make sure to cut them into bite-sized pieces for easier preparation.

Next, place the tomatoes in a vacuum-sealed bag and spread them evenly. Use a food vacuum sealer to remove all the air from the bag.

Seal the bag tightly and store in the refrigerator. Tomatoes stored this way can stay fresh for 1-2 weeks.

Preserve tomatoes by slicing them and canning them.

This is a traditional food preservation method that helps you retain the fresh flavor of tomatoes for a long time without the need for preservatives. Canned tomatoes can be eaten directly or used in many other delicious dishes.

Materials and tools: 2 kg of ripe tomatoes. Glass jars with lids.

How to do it: Wash the tomatoes under running water, then drain or pat dry with a clean towel. Remove the stems, then slice the tomatoes into small, bite-sized pieces (about 2-4 pieces depending on the size of the tomato).

Arrange the sliced ​​tomatoes in a sterilized glass jar. Leave about 2-3cm of space from the rim to prevent the tomatoes from overflowing during the sealing process.

Seal the jars tightly. Prepare a large pot, lining the bottom with a clean cloth to prevent the glass jars from cracking during heating. Arrange the tomato jars in the pot, and pour water to cover about two-thirds of the jars.

Turn on the stove and bring the water to a boil. Once boiling, reduce the heat and continue to steam the jar of tomatoes for about 90 minutes. The ideal temperature to kill bacteria and mold is around 92 degrees Celsius.

After boiling for the required time, turn off the heat and let the jar of tomatoes cool gradually in the water. Once the jar of tomatoes has completely cooled, you can remove it, dry it, and store it in a cool, dry place or in the refrigerator.

Store tomatoes in the refrigerator according to their ripeness.

Ripe red tomatoes

For ripe red tomatoes, wrap each tomato individually in newspaper or paper towels. The wrapping will help absorb excess moisture and limit direct exposure to cold air, helping the tomatoes stay fresh longer.

Arrange the paper-wrapped tomatoes in separate containers or trays in the refrigerator's crisper drawer. Setting the refrigerator temperature to 2-5°C and humidity around 85-90% is ideal for preserving tomatoes.

Ripe red tomatoes should only be stored in the refrigerator for a maximum of 1-2 days. After this time, the tomatoes may lose moisture, become wrinkled, and lose their flavor.

Ripe tomatoes

Tomatoes that are still unripe are best stored in the refrigerator at a temperature of around 4-5 degrees Celsius. This temperature helps slow down the ripening process, keeping them fresh for longer. Unripe tomatoes can be stored in the refrigerator for 4-7 days while still maintaining their freshness.

When you need to use them, you should take the tomatoes out of the refrigerator and leave them at room temperature for 1-2 days so they ripen naturally and have the best flavor.

The tomatoes are still green.

Place green tomatoes in a basket, tray, or paper bag. Avoid using plastic bags as they can trap moisture, causing the tomatoes to spoil quickly. Place the basket of tomatoes in a cool, dry place, away from direct sunlight. The ideal temperature for tomatoes to ripen naturally is around 18-21 degrees Celsius.

Check your tomatoes regularly. When they turn red and plump, they are ripe. You can transfer them to the refrigerator to slow down the ripening process and preserve them longer.
