If fresh lemons are stored directly at room temperature, they can be stored for about a month. However, it is necessary to ensure that the oxygen concentration in the storage area is not too low and the carbon dioxide concentration is not too high, so as not to affect the taste of lemon. In addition, lemon with hard and dense skin and enough weight should be selected when purchasing to ensure its good development and easy storage.

2, lemon juice preservation.

After squeezing lemon juice, it can be sealed with plastic wrap and stored in the refrigerator, but in order to avoid the volatilization of vitamin C, try to drink it within 3 days.

3. Save directly after slicing.

Wash the lemon, cut it into pieces, add some honey after cutting it, and then seal it directly in a container. At this time, put it in the refrigerator and seal it, which can keep fresh for about a month.

4, pickled and preserved.

Wash, cut, add sugar or rock sugar, and marinate. When eating, you can take out the lemon slices and soak them in water.

5. Seal with plastic film.

If you can't finish it the first time, you can cover the excess surface with plastic wrap and put it in the refrigerator. However, in order to ensure the taste and efficacy, it is recommended to eat it quickly in a short time.
