Long term storage method of okra, how to preserve okra

The long-term storage methods of okra include: refrigerator refrigeration, quick freezing, sun drying, temperature preservation method, etc.

1.Refrigerated storage method

1) Prepare the fresh okra, sprinkle some salt on top of it, and gently rub it with your hands to remove the small fluff, which can affect the taste, and it is best to remove it before saving.

2) Then remove the salt with clean water, wipe the water clean, put it in a plastic bag, and put it in the refrigerator of vegetables and fruits at a high temperature, so that it can be stored for a period of time.

2.Quick-frozen preservation

1) Handle the okra, then put it in boiling water, add a little salt, blanch for a minute, and then scoop it up to drain the water.

2) Next, we put the blanched okra in cold water, and after the okra is cool, we will take the okra out to control the water.

3) Put the okra in a plastic bag, put it in the freezer compartment of the refrigerator, and refrigerate it.

4) This method can keep it fresh for about nine months, and the longer it is stored, the more nutrients will be lost, and it is best to eat it in two weeks. to prevent nutrient loss.

3.Sun-dried preservation method

1) Wash the okra and let it dry in the sun, this method needs to be done in the hot summer, if it is winter.

2) After the okra is dried, collect it and put it in your pocket for preservation, which is stored in a reliable place and will be stored for a long time.

3) Sun-dried preservation of okra will lock all the nutrients of okra, and it needs to be soaked with water when cooking.

4.Temperature preservation method

1) The core of okra has a good breathing ability, and in a relatively low temperature environment, okra can be well preserved.

2) Of course, this preservation method is best stored when the temperature is relatively low, if it is found that there is yellowing or deterioration okra under ordinary preservation, it should be picked out in time to avoid infection to other okra.

3) When preservation, it is best to choose a good okra, not a fast deterioration okra, so that the preservation time is longer.

Introduction to okra

Okra usually blooms between May and September and prefers warmer conditions. It is a vegetable and is called the king of vegetables. Its origin is in India, it is resistant to dry heat and has a short growth cycle, and has been widely cultivated, and has also been introduced and cultivated in Shandong, Hunan, Yunnan, Guangdong and other provinces in China.

1.Okra can be refrigerated or frozen, so it can be eaten when frozen. 2.

Fresh okra generally lasts for about seven days in the refrigerator. It can be wrapped in white newspaper, then wrapped in a plastic bag or plastic wrap and placed in the refrigerator. 3.

It should be noted that because okra is easy to bruise and will turn black soon after being bruised, it must be picked and placed separately and cannot be squeezed, whether it is selected or stored. It is best to pack it in a plastic bag before putting it in the refrigerator, and try to lay it flat as much as possible. 4.

If you buy a lot of okra at once, you may not be able to eat it all in a day. That's when you need to think about how to save it. The best storage temperature for okra is 7 to 10 °C, which refers to fresh okra.

If not stored within this temperature range, fresh okra will quickly spoil, resulting in a poor taste and loss of nutrients. 5.To preserve okra, it is first necessary to have an understanding of its properties.

As we all know, okra respirates quite quickly at high temperatures, causing its tissues to age and turn yellow rapidly, leading to spoilage. A large number of scientific experiments have confirmed that okra is best stored at a temperature of 7 to 10, and the shelf life of fresh okra is about 10 days.

1.Okra is stored in 0 5 cold storage for 7 days. It can only be stored at room temperature for 2 to 3 days.

In the hot summer, the temperature is high, the water evaporates quickly, and the fruit surface is easy to be leathery and aged. Therefore, it should be harvested early in the morning, cut the fruit stalks, put the tender fruits into a fresh-keeping bag or plastic box, and then carefully put them into a carton or wooden box, and quickly send them to 0 5 cold storage for pre-cooling and waiting for transportation. The best time for pre-cooling is 18-24 hours.

2.At higher temperatures, okra causes rapid aging, yellowing and decay of tissues due to its rapid respiration. It is best to buy and eat on the same day, if you need to preserve, you can wrap it in white newspaper, then cover it with a layer of plastic bag or plastic wrap, and put it in the refrigerator for refrigeration, and the storage time is not recommended to exceed two days.

In addition, because okra is very susceptible to abrasions, and it will turn black soon after abrasion, it is necessary to pick and place it individually and do not squeeze it when picking or storing. It is best to pack them in a plastic bag before putting them in the refrigerator and try to let them lie flat as much as possible.

Okra is highly nutritious but difficult to preserve, teaching you the correct way to preserve it, it is really a knowledge.

The long-term preservation methods of okra include quick-freezing preservation, freeze-drying preservation, and blanching preservation.

1. Quick-frozen preservation.

If you want okra to be stored for a long time, it is best to blanch it and then quick-freeze it to keep it fresh, so that its freshness period can reach 9 months. At a relatively high temperature, okra can be stored at too high a temperature due to its rapid respiration, which will cause rapid aging, yellowing, and even decay of tissues.

2. Lyophilized storage.

Dry preservation is a way to preserve food with well-preserved nutrients, generally using the freeze-drying method of vacuuming, freezing the water in okra into ice, and then volatilizing the water vapor in a relatively high vacuum environment, so that the nutrients in okra will be preserved to the greatest extent.

3. Blanch and preserve.

Fresh okra is easy to age, resulting in uncomfortable eating, at this time you can put the okra in boiling water to blanch, and then dry it in cold water to drain the orange water.

Okra planting

1. Planting in land preparation.

Okra can be grown in the open air from April to August every year, and it can be eaten in the same year, and if it is planted in a greenhouse, it can be sown and harvested early. Okra is generally seeded, and the seeds can be soaked in warm water for one day for germination treatment before sowing. Okra is not very demanding on the soil, but loose, fertile, well-lit soil increases yields.

Turn the soil deep before planting, and then apply enough basal fertilizer, mainly organic fertilizer, okra should not be stubble.

2. Field management.

After the okra emerges, it is necessary to carry out weeding in time to prevent weeds from competing with it for nutrients. After each fertilization, a tillage should be carried out to prevent soil compaction from affecting the growth of okra. If the planting density is large, the bottom side branches can be appropriately cut off at a later stage.

Okra grows quickly during the fruiting period, and if there are many storms in the area, bamboo poles can be planted to prevent lodging.

3. Water and fertilizer management.

Okra has a long growing period and large plants, so there is a great demand for water and fertilizer. Under the premise of applying sufficient basal fertilizer in the early stage, topdressing should be carried out many times, and the first topdressing should be carried out after the emergence of seedlings, mainly urea. More fertilization should be applied during the fruiting period to promote high yields.

Okra is more drought-tolerant, the seedling stage does not require much water, pay attention to the moisture of the soil in summer, and remove the stagnant water in time after rain to prevent rotten roots from dying.

4. Pest control.

Okra has relatively few pests and diseases, and there will be disease spots on the branches and leaves when it rains, and the infection can be controlled by sprinkling lime after the weather is sunny, and the appropriate amount of Bordeaux liquid can be sprayed in the early stage for control. The main insect pests are aphids, ground tigers, etc., which can be sprayed with carbaryl wettable powder.

Here are a few common ways to preserve okra for a long time:

1.Cryopreservation: Okra is washed and cut into small pieces or slices, placed in a sealed bag to remove as much air as possible, and then placed in the freezer for freezing.

Frozen okra can last from a few months to a year. When using, you can put the frozen okra flakes directly into the cooking, and there is no need to thaw them.

2.Dehydration preservation: Cut the autumn kernel sunflower into small pieces or slices, and then put it in a dehydrator for dehydration treatment until the dehydration is dry. Dehydrated okra can be stored for a long time, kept in a dry, cool place, or kept tightly sealed in jars or airtight bags.

3.Vinegar preservation: Wash the okra, remove the stems from the top, and place in a bottle or container.

Fill the container with vinegar, making sure all okra is completely soaked in vinegar. Cover the container tightly and store in a cool place. Vinegared okra can last from a few months to a year.

4.Preservation of dew and vegetable fresh-keeping bag: Wash the okra, wrap it in a kitchen towel or absorbent paper, and then put it in the dew and vegetable fresh-keeping bag.

Keep the inside of the bag dry and place it in the refrigerator vegetable room or freezer for preservation. This method allows okra to last for a few days to a week.

Whatever method you choose, make sure okra is clean and fresh before storing it. At the same time, pay attention to sealed storage and avoid the influence of factors such as moisture and high temperature on okra to prolong its preservation time.

Okra is prone to respiration too quickly at higher temperatures, leading to tissue aging, yellowing, and decay. Therefore, when storing okra for a long time, you need to pay attention to the following:

1.Quick-frozen preservation: Blanch the picked okra in boiling water for 1 minute as soon as possible, then remove the super-cooled water and dry the water.

Place the blanched okra in portions into a plastic bag and store in the freezer. This method can keep it fresh for 9 months, but the longer it is kept fresh, the more the nutrients of okra will be lost, so it is recommended to consume it within two weeks.

2.Dry and preserve: Blanch fresh okra in boiling water and remove to dry. Dry okra in the sun and keep it sealed after drying. After drying, okra can be stir-fried or soaked in water to drink.

3.Refrigerated storage: Trim the stalk of okra completely, put it in a plastic bag or crisper box, and put it in the cold compartment of the refrigerator, preferably set the temperature of the cold compartment between 5 and 9 degrees, so that it will stay fresh for a week.

In conclusion, in order to maintain the freshness and taste of okra, it is recommended to handle and preserve it as soon as possible after harvesting. If the purchase quantity is large, you can take the method of picking, processing and storing in batches to avoid the spoilage of okra.

Okra storage 1General refrigerator refrigeration storage method (1) Prepare fresh okra, sprinkle with some salt, and gently rub it with your hands to remove the small fluff, which will affect the taste. It's best to remove it before saving.

2) Then use water to remove the salt, wipe off the water, put it in a fresh-keeping bag, and put it in the high-temperature fruit and vegetable refrigerator, which can be stored for a period of time. 2.Quick-frozen okra preservation method (1) Handle the okra, then put it in boiling water, add a little salt, blanch for one minute, then remove and drain the water.

2) Next, we put the blanched okra in cold water, and when the okra is completely cooled, take it out and control the water. (3) Put the water-controlled okra into a plastic bag, put it in the freezer compartment of the refrigerator, and refrigerate. (4) This method can keep it fresh for about nine months.

The longer it is stored, the more nutrients are lost. It's best for everyone to do it within two weeks. Prevent nutrient loss.

Okra storage 3Sun-dried preservation method (1) Okra is washed and then left to dry in the sun. This method needs to be done in the hot summer, and if it's winter, forget it.

2) After the okra is dried, collect it and keep it in your pocket. The storage location is reliable, and the storage time will be longer. (3) Drying and preserving okra will lock in all the nutrients of okra.

When cooking, you need to soak it in water.

Cut off the damaged areas on the outside of okra with a knife and wrap the incision in plastic wrap. Wrap the okra in two to three layers with newspaper, and then wrap one layer in a plastic bag on the outside. Place the okra in the refrigerator.

During the process, it is necessary to replace the newspaper on the outer layer of okra every three to four days. <

1. Cut off the damaged part of the okra with a knife, and then wrap the incision of the chadenier reed with plastic wrap, and there is no need to clean the okra in the process.

2. Wrap two to three layers of okra with newspaper, and then wrap one layer with a plastic bag. Newspapers are used because they can absorb the moisture brought out by okra's respiration and ensure a certain degree of dryness inside the okra.

3. Put okra in the refrigerator. During the process, the newspaper on the outer layer of okra needs to be changed every three to four days, so that the okra can sit for a long time.

1. Okra can be frozen and preserved. Okra fruits were refrigerated (-18) by quick-freezing method to study its effect on the main quality of okra fruits and their storage and preservation period.

2. At the same time, it should be noted that because okra is very susceptible to abrasions, and it will soon turn black after injury, it should be picked and placed separately and not squeezed, whether it is selected or stored. It is best to pack them in a plastic bag before putting them in the refrigerator and try to let them lie flat as much as possible.

3. It is best to buy and eat on the same day, if you need to preserve, then you can wrap it in white newspaper, and then cover it with a layer of plastic bag or plastic wrap outside, and then put it in the refrigerator for refrigeration. (It is recommended to eat it within two days, otherwise it will be easy to age). It is best not to touch ice cubes or ice water directly when storing, because the low temperature environment will quickly make okra soft and rotten.

4. Okra can be frozen and stored, and the okra fruit should be refrigerated (-18) for preservation by quick-freezing method, and its effect on the main quality of the fruit and its storage and preservation period should be studied. If okra is at a higher temperature, its respiration is quite rapid, which makes it cause rapid aging of tissues, yellowing, and leading to spoilage and putrefaction. After a large number of scientific experiments, okra is best stored in an environment of 7 to 10 years, and fresh okra has a storage period of about 10 days.
