How to keep raw cucumbers fresh and how to preserve cucumbers

First, the sand storage method in the strong cold snap before the day before the arrival of the autumn cucumber, watering the autumn cucumber, let it fully absorb water, cut it from the melon handle with scissors when picking, handle it gently, and hide it with picking. When storing melons, spray water on the fine sand that is fried dry and ready for use, first spread a layer of wet sand in the tank, and then put a layer of cucumbers and a layer of sand, a total of 7-8 layers of melons. The tank is placed indoors, as long as the temperature is suitable, it can be stored for about 30 days, and the color and umami are basically unchanged.

Second, the jar storage method cucumber harvesting is the same as above. Brush the tank in advance, fill it with 10-20 cm deep water, put a tic-tac-toe wooden frame at 7-10 cm from the water surface, put a round grate made of reeds on the shelf, put cucumbers flat on the grate, melon inward, stack along the cylinder wall, park when 10-12 cm away from the cylinder mouth, seal the cylinder mouth with kraft paper, put the cylinder indoors, take thermal insulation measures after the weather becomes cold, and avoid being less than 10.

Third, the low-temperature controlled atmosphere storage method after picking the cucumber into a plastic bag with a specification of 40 50 cm and a film thickness of millimeters, each bag is 2-3 kg, and then the bag is packed into a basket and stacked up, placed in a constant temperature of 3, the gas index is controlled as: oxygen 3%-5%, carbon dioxide 8%-10%, using this method, cucumber storage for one month without rotting and dehydration.

Eat as much as you want, buy as much as you want, eat and buy the freshest.

Wrap in plastic wrap and refrigerate in the refrigerator, do not freeze;

Or wrap in plastic wrap and place in cold water.

The optimal temperature at which cucumbers are stored varies with the length of storage. The most suitable temperature for short-term storage is 1-5, and the relative humidity is 95-98%. If you want to store it for a long time, a temperature of 10-13 and a humidity of 90-95% are ideal. For long-term storage, cucumbers harvested in late autumn should be selected.

Under the premise of not being subject to frost, the later the sowing date and the later the harvest, the more conducive to storage. Water well before harvesting. When harvesting, it is advisable to cut the melon handle with scissors with 3 cm in the morning or evening when the temperature is low, and handle it gently, do not rub off the melon thorns or touch the melon skin, and pack it in a wire basket covered with plastic film.

There are many ways to preserve cucumbers, specifically:

1 Indoor storage. The cucumbers in the wire basket are carried into a cool and ventilated warehouse, and the mouth of the basket is sealed with plastic film. There is no need to move for half a month, and the cucumbers harvested in mid-September are just stored until the National Day to be marketed.

2 Jars. Wash and scrub the vat and place it in a cool storage room. Pour 10-20 cm of cold water into the tank first, and place a straw curtain 8-10 cm above the water surface, and place cucumbers on top of the curtain.

Three pendulum methods can be used: the cucumbers are placed horizontally and vertically, and the cucumbers are placed vertically and vertically to a distance of 10 cm from the cylinder mouth; Place it in a circle along the cylinder wall, with the head facing inwards and the tail facing outward, and the center of the cylinder is empty, until it is 10 cm away from the cylinder mouth; For every two layers of cucumbers, place a straw curtain that can jam the wall of the cylinder, and swing it until it is close to the mouth of the cylinder. After it is placed, the cylinder is strictly pasted with kraft paper every day, and the large tank containing five quintals of water can store about 100 kilograms of cucumbers, which can be kept fresh for one month.

When the temperature drops, half of the cylinder can be buried in the ground, the top of the cylinder is covered with a straw curtain, and a layer of thick mud is smeared on the curtain. Grass bags and sacks around the tank are cold-proof, and the principle of not freezing inside is good, and it can be stored until the New Year.

3. For ordinary cellars, before and after the cold dew, choose a cellar with a depth and width of about 1-3 meters in the shade, and the length can be determined according to the size of the storage. The shed is covered, and a mouth is left in the middle of the cellar, and a ventilation tile pipe is installed at one end of the top of the cellar. Then spread a layer of smooth straw with leaves removed around the cellar and at the bottom of the cellar, and the selected cucumbers can be stacked on the straw.

Cover the cellar mouth tightly, check the cellar every sunny day, and pick out the spoiled cucumbers in time. It can be stored for about 1 month in this way.

4 sets of cellars. Dig a small cellar l meters deep in a normal cabbage cellar, or dig a hole like an air raid shelter in the wall of the cabbage cellar. Spread a layer of wet straw at the bottom, put 5 layers of cucumbers on top, cover with a layer of wet straw, put 5 layers of cucumbers, also cover the top with wet straw, pile up to about half a meter, pour a stack every 5-7 days, and store it until the New Year if it is well kept.

5: There are some vegetables and fruits that are suitable for mixing and ripening, which is different sensitivity to ethylene. Tomatoes and cucumbers in fruits and vegetables are sensitive to ethylene, so it is best not to mix them with apples, pears, bananas, etc.

Eggplant is one of the vegetables with strong adsorption, so don't mix it with green onions, ginger and garlic, it is easy to carry over the flavor.

The correct way to store cucumbers, no need to put them in the refrigerator, they are still fresh for 7 days, simple and practical.

Cucumber preservation and storage methods: wrap plastic wrap and put it in the refrigerator, pre-cool it and put it in cold storage, decompression storage (plastic bag vacuum), preservative storage;

Preservative storage: cucumbers can be soaked in the prepared preservative solution, take out a little dry after 30min, then put into a plastic bag, tie the bag tightly, store it under the condition that the temperature is 12 14 and the humidity is 90 95%, open the bag every 10 days, and dry the water vapor in the bag for about 1h;

Reduced-pressure storage: put the cucumber in a plastic bag and seal it, and store it at a temperature of 12 14 and a humidity of 90 95%;

Refrigerator storage: Wrap cucumbers in plastic wrap and put them in the refrigerator drawer to keep them fresh;

Cold storage storage: cucumbers are placed in a fresh-keeping warehouse with a temperature of 12-14 and a relative humidity of 90-95%; The storage cycle of cucumbers in cold storage is 1-2 weeks;

Cucumber is sensitive to temperature above 15 during storage, and when it is higher than 15, it is easy to turn yellow and senescence, and the temperature should be controlled at 10 13. Cucumbers are sensitive to carbon dioxide, so more attention should be paid to ventilation during storage.

1.Salt soaking method:

In summer, when the temperature is hot, you can soak the cucumber in it after dissolving part of the salt in the water, which can extend the shelf life of the cucumber to about 20 days.

2.Running water brewing method:

If there is plenty of around. Water source, you can use flowing water such as rivers and streams, which can also effectively extend the shelf life of cucumbers.

3.Chinese cabbage preservation method:

In autumn, after picking cucumbers, put them in the core of Chinese cabbage, and put two or three sticks of each cabbage. Then tie the orange and put it in the vegetable cellar, which can be stored until spring, and the melon flavor is still fresh.

Two days.

Put the cucumber in the plastic bag first, then put water in the noodles, and then pour the water out, then there will be some water in the bag, so that's it! It can be left for a long time.

1. The cucumber in summer is not well preserved, and it will grow white hair, and the melon will rot. This is mainly because cucumbers have a lot of water, vigorous respiration and emit a lot of heat, coupled with high temperature and humidity in summer, which will cause microorganisms and mucormycetes scattered on cucumbers to multiply, so cucumbers will grow white hairs.

2. Cucumber is sweet, sweet, cool, bitter, non-toxic, and enters the spleen, stomach, and large intestine; It has the effect of removing heat, diuretic, clearing heat and detoxifying; Indications for polydipsia, sore throat, burning eyes, fire burns. There is also a ** effect.

1.After cleaning the cucumber, take it out, re-connect a basin of clean water, add an appropriate amount of edible salt, soak the cucumber in it after stirring the edible salt, you must know that the edible salt has a good bactericidal effect, so that we can see that the surface of the cucumber will float some small bubbles, which means that the cucumber is breathing, and the salt water can also ensure that the water on the surface of the cucumber is not lost, prevent the reproduction of microorganisms, and the third place is placed in a cool and ventilated place, so that the preservation time of the cucumber can be effectively extended.

2.Wash the cucumber in clean water several times, then drain the water, dig the paper carefully with a napkin to dry the surface moisture, and then wrap the cucumber with toilet paper, because toilet paper has a good heat and cold insulation effect, and can also absorb water.

3.Then put it in a clean plastic bag, drain the water inside, and put it in a cool and ventilated place, so that you can effectively prolong the preservation time of cucumbers.

4.If you are really lazy and don't want to use the above two methods, then we can also put the liquid cucumber in the vegetable basket, and the vegetable basket is placed in a cool and ventilated place, so that the cucumber can also be kept fresh for about a week.

5.If you put it indiscriminately, the cucumber is easy to grow white hairs when exposed to high temperatures, thereby accelerating aging and softening.
