Method 1:

It can be stored in the refrigerator. If it is not peeled, the leaves on the head need to be pinched off and stored separately, so it can be stored for about two days without the refrigerator. If it is peeled lettuce, it needs to be sealed with plastic wrap or plastic wrap before it is released. The low temperature in the refrigerator can inhibit the growth of harmful microorganisms, so it can be sealed with plastic wrap and stored in the freezer for about five days. If there are no deterioration phenomena such as softening, reddening, odor and mildew, you can continue to eat.

Method 2:

Lettuce can be preserved by soaking in water. First, the lettuce is soaked in water until it reaches one third of the lettuce to keep it upright, and it can be stored at room temperature for 3-5 days.
