1、 Are they genetically modified vegetables

Lettuce is not a genetically modified vegetable, but it has been studied. Now common genetically modified foods are soybeans and corn, and others are very uncommon. In addition, tomatoes are also genetically modified, but the taste is not very good. The skin is thicker than usual, so it is rare at present. Since it is not genetically modified, it can be safely eaten. Even babies can eat it, but in an appropriate amount

2、 Preservation method

1. Refrigerator preservation: after washing the lettuce, wipe the water on it with a paper towel, bind the leaves with a rope, and then put them in the refrigerator for preservation. But be careful not to let its leaves touch the inner wall of the refrigerator. But the storage time should not be too long. It can only be stored for about 3-5 days. If it is too long, the taste will become very poor

2. Fresh keeping bag: if you don't put it in the refrigerator, you can wipe the water on the lettuce, put it in the fresh-keeping bag and place it in a cool place for about 3 days

3、 Precautions

When saving, be careful not to put it together with mature apples and bananas, otherwise it is easy to cause reddish brown spots on the leaves of lettuce. And be sure to dry the water before putting it into the refrigerator
