Lettuce is not a genetically modified vegetable, but it has been genetically modified.Now the 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 very rare at present.Since it does not belong to genetically modified, it can be safely eaten, even the baby can eat, but to the right amount.
1. Refrigerator preservation: After washing the lettuce, wipe the water on it with a paper towel, tie 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, only about 3-5 days, too long, then 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 put it in a cool place, which can keep it for about 3 days.
When preserving, be careful not to put it with ripe apples and bananas, otherwise it will easily make the leaves of lettuce appear reddish brown spots.And before you put it in the refrigerator, you must dry the water first.
