How can tomatoes be preserved longer?

Tomatoes can be preserved by making tomato sauce. Other saving methods are as follows:

1. Refrigeration method

Mature tomatoes should be refrigerated at 2 ~ 4℃ and kept fresh and nutritious within 10 days. If the temperature is too low, tomatoes will lose their flavor due to frostbite and rot quickly.

When tomatoes are refrigerated, they will emit a gas called "ethylene", which will ripen the vegetables and fruits together and shorten the shelf life. Therefore, it is best to put tomatoes alone or wrap them in fresh-keeping bags when they are refrigerated.

2. Quick freezing method

After buying it, wash it, dry the surface, put it in a food bag and then put it in the freezer of the refrigerator. After three hours, it basically froze. If you put it in the refrigerator, you can take it out and thaw it at any time in winter, and you can cook it. It's delicious and nutritious.
