Lettuce is a very common leafy green.

It is also the favorite of the ** people. For many people, lettuce is a must-eat vegetable during the ** period. Lettuce is crisp and delicious, can be fried or eaten raw, and the nutritional value is very high; But be careful, be sure to wash the lettuce before eating it.

However, lettuce is generally easy to wilt and rot after a few days, how to properly preserve lettuce to keep it fresh? Let's learn together.

1. Keep fresh at room temperature.

Wrap the fresh lettuce with a paper towel, the paper towel has a strong effect of absorbing moisture, which can prevent the lettuce from turning yellow or wilting, and can also play a good role in heat insulation.

Wrap it again and store it in a cool, ventilated place.

2. Refrigerator freshness.

Wipe the water on the lettuce with a paper towel, then tie up the loose leaves with a strip of paper or cloth, etc., and put it in the refrigerator to keep it fresh, and the refrigerator can be kept fresh for 3 to 5 days. Lettuce moisture will affect the preservation of lettuce in the refrigerator, before putting it in the refrigerator should be cleaned of the water droplets on the leaves, you can also put a paper towel under the lettuce to absorb excess water.

3. Keep it in a fresh-keeping bag.

If the weather is cold, you can dry the water droplets on the lettuce leaves with a paper towel, tie them and then put them in a plastic bag, and store them directly in a cool place, which can be stored for three days.

4. Salt preservation.

Pour an appropriate amount of salt into a basin filled with water.

Stir well by hand, and then put the fresh lettuce that needs to be preserved into the salt water, the amount of water should not exceed the lettuce, and change a pot of salt water every two or three days, and the lettuce can be stored for about a week.

If the lettuce has been left for a long time and there is a moldy situation, it must not be eaten at this time, so as not to cause health hazards. I hope you can understand how to preserve daily vegetables through the introduction, and in daily life, we must avoid eating moldy and spoiled vegetables and fruits.

The lettuce will gradually soften and change color after a while, you can remove the cabbage sum, then stuff a moist paper towel into the cabbage sum to let the lettuce absorb the water, wait until the paper towel is dry, and then put the lettuce in a plastic bag to refrigerate.

Here's how:

Prepare a bowl and several sheets of wet wipes.

1. Put the paper towel in the water and let it fully absorb the water.

2. Shake off the excess water and wrap the lettuce stalk with a wet paper towel.

3. Put the lettuce in a bowl and refrigerate it.

a) Harvesting requirements.

The harvesting requirements for leaf lettuce are not strict, and it can be harvested and marketed at any time according to market demand. The lettuce can be harvested from the beginning of the ball-setting and pumping, and it is generally better to harvest the leaf balls in time when the leaf balls are tight. It should be harvested on a rainless day, irrigation should be stopped 1 2 days before harvesting, and no harvest should be made 1 2 days after rain.

2) Storage characteristics.

Lettuce has a high water content, crisp and tender tissues, and a freezing point, which is susceptible to frost damage. The storage temperature should be 0 3, and the relative humidity should be above 98%. It can only be stored at room temperature for 1 to 2 days.

3) Storage and transportation methods.

1.Simple storage lettuce has strong respiratory metabolism after harvest, and needs to be pre-cooled to 1 in time, and then packed into a film, do not seal, and enter the cold storage at the right temperature for 10 15 days. It should be noted that lettuce should not be mixed with apples, pears, melons, etc., because these vegetables and fruits produce more ethylene gas, which will cause rust spots on lettuce leaves.

2.Before the temperature drops to 0 before the winter of false planting, the lettuce cultivated in the open field can be uprooted, and the leaves can be slightly wilted after a little drying to reduce mechanical damage.

The next day, you can stock up on false plants in the pendulum. Loose leaf lettuce is stockpiled one by one; There should be a slight gap between the bulb lettuce plants for ventilation. Bury it with soil and do not water it. Check once every 15 or 20 days, and find that the yellow and rotten leaves are removed in time.

The shed is ventilated during the day, and half or fully covered at night, so that it is not frost damage, heat, and direct sunlight. Loose leaf lettuce can be stored for about a month; Bulb lettuce can be stored for about 10 days.

3.The lettuce is tender and perishable, and should not be transported over long distances. Short- and medium-distance transportation also needs to be pre-cooled first. When the transportation time is less than 1 2 days, the transportation environment temperature is required to be 0 6; When the shipping time is 2 3 days, it should be kept 0 2.

We can evaporate the water from the surface of the lettuce, then wrap it in a paper towel and put it in a bag, and then put it in the refrigerator for preservation. One thing to remember is that lettuce should not be put directly in the refrigerator, otherwise the lettuce will turn yellow and lose its crispness.

We can also put lettuce directly in the crisper box, but we need to put a layer of paper towel inside to better absorb moisture and thus keep the lettuce fresh for longer. Lettuce cannot be stored with fruits, and it is easy to cause vegetable spots.

Lettuce can be kept in the refrigerator for a few days.

Lettuce can last up to a week if it is stored in the refrigerator. First of all, when we buy, we must choose lettuce that is not damaged, and when we put it in the refrigerator, it is best to store it in a crisper box. Otherwise, lettuce is prone to frostbite.

And lettuce is very easy to oxidize, once the chlorophyll is lost, then the lettuce will turn red, so lettuce should be eaten in time.

Can cooked lettuce be kept in the refrigerator.

Cooked lettuce should not be put in the refrigerator, because lettuce itself contains nitrate, and after high temperature cooking, it will be converted into nitrite when put in the refrigerator, which will affect the health of the body and cause us to cause cancer, so we are discouraged from putting it in the refrigerator.

Store at room temperature.

Lettuce is a vegetable that contains more water and is easier to deteriorate, generally starting from the cabbage sum, therefore, in the case of low ambient temperature, the lettuce can be removed, and then the water is drained, wrapped in a fresh-keeping bag, placed in a cool and ventilated place, and can be stored for a longer time.

Keep in the refrigerator. The humidity of the refrigerator is high, and the lettuce contains more water, which is easy to turn yellow and wilt when put into it directly, which affects the taste of the lettuce, so after draining the water of the lettuce, it is wrapped in a fresh-keeping bag and put it in the refrigerator, which can isolate the moisture and alleviate the yellowing and wilting of the lettuce.

1 How to keep lettuce fresh in the refrigerator.

It is better to air dry the water droplets on the surface of the lettuce, and then choose to wrap the whole lettuce with a clean paper towel, and then put it in a bag and put it in the refrigerator for preservation. Of course, you can also directly spread a layer of paper towels in the refrigerator crisper box, which can absorb moisture and prolong the freshness of lettuce.

Note: Green leafy vegetables such as lettuce are easy to turn yellow and wilt after being put in the refrigerator, which is easy to cause lettuce to lose its crisp taste, so it is best not to put lettuce directly in the refrigerator for preservation.

2 How to keep lettuce for a long time.

When preserving lettuce, try using a crisper bag. If the weather is relatively cold, at this time, you can directly dry the water droplets on the lettuce leaves with a paper towel, and then use a paper strip to tie the lettuce leaves, you can directly put it in a fresh-keeping bag, and then put it in a cool place for preservation, this method can keep the lettuce for three or four days.

Note: When storing lettuce, it is best to remove the choy sum from it. The main reason is that choy sum is the part of lettuce that is most likely to deteriorate when it is preserved.

3 Lettuce can last for a few days.

Lettuce is generally not long when preserved, under normal circumstances, the lettuce is preserved after a simple treatment, it can be preserved for three to five days, and although lettuce can be extended after reasonable treatment, but because lettuce is a green leafy vegetable, it is better to eat lettuce as early as possible, so as to avoid storing it for too long and breeding bacteria, and can also avoid leaf deterioration, and after placing the lettuce, We need to take it out again for cleaning, otherwise it will cause the lettuce to be contaminated with bacteria.

Hello, the preservation of friends generally requires low temperature, as long as the temperature is low, it is better to keep warm, then it must not feel like air is very good to preserve.

Refrigerator to keep fresh. Wipe the water on the lettuce with a paper towel or air dry it directly, then tie up the loose leaves with a strip of paper or cloth, etc., and put it in the refrigerator to keep it fresh. Note that lettuce should not be placed next to the wall, otherwise it will frostbite the leaves.

Refrigerator freshness can keep lettuce for 3-5 days. After being left for a long time, the leaves are easy to turn yellow and rot, and the taste becomes worse.

Refrigerate in a plastic bag.

1.Store at room temperature.

If it is in the cooler season, the lettuce we buy back can actually be stored at room temperature, but when preserving, we need to pay attention to one point, we must take the lettuce out of the plastic bag, and spread it out for storage, generally using this method can be stored for about two days, but if the air environment is relatively dry, the general water loss is relatively fast, so within two days, we must eat all the lettuce.

2.Sprinkle water to save.

Another way is to put the lettuce bought back in the refrigerator for refrigeration, but in order to make the lettuce taste more refreshing and delicious, and the preservation time can be longer, it is best to spray some water on the surface of the lettuce every day, but the amount of water should not be too much, if it is too much, it will cause dampness, proper water can ensure that the lettuce is sufficiently hydrated, the water is sufficient, and the natural freshness will be higher.

1. It can be put in the refrigerator: wipe the water on the lettuce with a paper towel or air dry it directly, then tie up the loose leaves with a strip of paper or cloth, etc., and then put it in the refrigerator to hold the cover to keep it fresh.

2. It can be put into a fresh-keeping bag: wash the lettuce spine base and dry it, put it into a fresh-keeping bag, and then store it directly in a cool place, which can generally be kept fresh for about 3 days.

3. Remove the cabbage: The cabbage is the part of the lettuce that is more likely to deteriorate, and the lettuce can be stored in a cool place for about 2-3 days after picking the cabbage.

Lettuce due to high water content, poor storage resistance, easy to lose water wilting phenomenon, suitable for 0-3 storage, family purchase should be put in the refrigerator in time to refrigerate preservation, such as the lettuce just purchased surface moisture more, in order to reduce the rot caused by excessive humidity, need to remove the surface moisture of vegetables before preservation. Because lettuce tissue is brittle and tender, it is very susceptible to browning caused by mechanical damage, so it should be packed in thin plastic wrap or plastic bag before being stored in the refrigerator. <

1. Lettuce due to high water content, poor storage resistance, easy to dust and water wilting, suitable for 0-3 storage, family purchase should be put in the refrigerator in time to refrigerate, such as the lettuce just purchased more surface moisture, in order to reduce the rot caused by excessive humidity, the surface moisture of the vegetable needs to be removed before the storage of the sail stove.

2. Because the lettuce tissue is brittle and tender, it is very susceptible to browning caused by mechanical damage, so it should be packed with thin plastic wrap or plastic bag before being stored in the refrigerator.

3. Because lettuce is very sensitive to ethylene, it should be avoided to be stored with bananas, ripe apples and other fruits to avoid inducing russet spots.
