How do you keep shaved sweet potatoes for three months?

1. Slice preservation.

People in many areas like to eat dried sweet potato porridge, so we can wash the sweet potatoes, cut them into long slices or long strips, dry them, and store them in a plastic bag. Take it out when you eat it.

2. Cellar preservation.

Friends who live in rural areas know that every family is inseparable from a cellar where grain is stored, dig a pit in the field, and then put sweet potatoes in it and cover it with some sealed plastic sheeting. And it is stored for a very long time, and it will not be broken for a year.

3. Ventilation and preservation.

This method is the most common and acceptable to most people. First of all, we separate the sweet potatoes we bought according to the quality of the potatoes, pick out the sweet potatoes with disease spots or other problems, leave the sweet potatoes without any dirt, any damage, and no broken skin, and put them in a ventilated place to dry, the environment must be dry, and there is no moisture, so that the sweet potatoes will not rot. After air drying, pick out the spots that are spotted, rotten or broken skin, otherwise it will affect the preservation of the remaining good sweet potatoes.

After selecting the sweet potatoes, use waste newspapers and wrap each sweet potato in waste newspaper to avoid friction between sweet potatoes and sweet potatoes. Prepare a dry and clean cardboard box, put the sweet potatoes in one by one, and put an apple in at the end. The purpose of putting apples is to prevent the sweet potatoes from sprouting and affecting the taste of the sweet potatoes when they are stored for a long time.

After packing the carton, you can put it in a ventilated place, and you can take it as you go.

Shaved sweet potatoes can't be stored for three months at natural temperatures. You can shave sweet potatoes into thin slices, let them dry in the sun, and leave them for a year. This is dried sweet potato.

After digging up the fresh sweet potatoes, stir up the soil on the surface and leave them in the sun for about 2 hours, then find a larger cardboard box, put the sweet potatoes in it and seal it, and put the carton in a cool place indoors. The temperature should be controlled at about 15, open the lid to ventilate in good weather, and add a few wooden boards in cold weather.

In the past, in rural areas, the dug sweet potatoes were put directly into the cellar, so that the sweet potatoes could be stored for a long time. It doesn't matter if you don't have a similar cellar, you can find a larger cardboard box, put all the sweet potatoes in it and seal it, and then put the carton in a cool place indoors, but not damp.

Before putting sweet potatoes in a cardboard box, they can be placed in the sun for 2 to 3 hours to reduce water loss. After putting in the carton, put the carton in the corner and against the wall, when the weather is good, you can also open the lid to breathe, but do not blow the cold wind in, when the weather is cold, you can add a few wooden boards around the carton to keep warm.

When the surrounding environment is cold, the sweet potato will be frozen, and the sweet potato heart in the center will harden, and it cannot be cooked during cooking, so it can no longer be eaten; When the surrounding environment is hot, sweet potatoes will sprout again. Therefore, it is best to control the temperature at about 15, so that the sweet potatoes will not only not spoil, but will also become sweeter and sweeter.

Summary. 3. Water is also one of the reasons for its cracked skin, when the sweet potato tuber expands rapidly, if there is too much water, it will expand rapidly when it absorbs too much water, but the epidermis growth rate cannot keep up, and the cracked skin appears. 4. The moisture is uneven during the growth period, and in the case of long-term drought, it will suddenly be flooded, and the same situation will occur as above.

5. In addition, there is a certain reason for underground insect pests, especially the boring needleworm, which will destroy the epidermal tissue of sweet potatoes, causing the cortex to crack and form a huge crack.

1. Sweet potatoes are mainly caused by soil, it is suitable for growing in sandy soil, if it grows in clay minra, due to soil compaction, poor air permeability, it will easily lead to the phenomenon of cracked skin. 2. The second is the problem of nutrients, if there is a lack of boron and calcium in the soil, the skin of the sweet potato is more fragile than the bridge slag, and it is easy to be cracked, resulting in cracking.

3. Moisture is also one of the reasons for the cracking of the kernel of the sweet potato tuber, when the sweet potato tuber expands rapidly, if there is too much water, the cavity will dry up to its excessive water absorption and rapid expansion, but the epidermis growth rate can not keep up, and the cracked skin appears. 4. The moisture is uneven during the growth period, and in the case of long-term drought, it will suddenly be flooded, and the same situation will occur as above. 5. In addition, there is a certain reason for underground insect pests, especially the boring needleworm, which will destroy the epidermal tissue of sweet potatoes, causing the cortex to crack and form a huge crack.

Sweet potatoes can be stored overnight after peeling, and they can be stored in a container at room temperature, or they can be stored in a plastic bag and then in the refrigerator. Sweet potato is a sweet potato plant of the family Spinaceae, also known as sweet potato, sweet potato, vermilion potato, golden potato, sweet potato, red yam, etc., native to South America and the Greater and Lesser Antilles.

Sweet potato Chi was first planted in Mexico and Colombia in the middle of the Americas, and was brought to the Philippines and other countries by the Spaniards to be planted, and the sweet potato was first introduced to China in the Wanli period in the late Ming Dynasty.

Sweet potato is a nutritious and rich natural nourishing food, containing protein, fat, polysaccharides, phosphorus, calcium, potassium, carotene, vitamin A, vitamin C, vitamin E, vitamin B1, vitamin B2 and 8 amino acids.

Sweet potato is a high-yield and adaptable food crop, which is closely related to industrial and agricultural production and people's lives, in addition to being the staple food, it is also an important raw material for food processing, starch and alcohol manufacturing industry, and the roots, stems and leaves are excellent feed.

<>1. You can wrap the sweet potatoes in plastic wrap and put them in the ice empty repentance box and refrigerate. In addition, you can also soak the peeled sweet potatoes in the brine of the low-concentration pre-balance.

2. In addition, you can also soak the peeled sweet potatoes in low-concentration sugar water. However, in general, peeled sweet potatoes are more likely to spoil and should not be stored for too long, so if the sweet potatoes are peeled, they should be eaten as soon as possible.

Some sweet potatoes need to go through"Processing"to be able to get out of the water"Unplug it": In a normal year, sweet potatoes need to be stored on the same day. A normal year means no extreme weather and normal rain.

Because when the sweet potatoes are harvested, it is autumn and the weather is dry, so when the sweet potatoes are planed, the soil is loose, and after the sweet potatoes are planed, the sweet potatoes are naturally separated from the soil, and the moisture in the sweet potatoes is moderate, so it does not need to be dried and should be stored on the day after harvesting.

<> freshly shaven sweet potatoes, which are in the late stages of growth, are not complete"Mature", after warehousing, there are"After ripening"The stage, that is, the nutrient transformation period, if it is dried, it will lose more water, which has an inhibiting effect on nutrient transformation, resulting in poor quality, which is not conducive to storage. The water vapor in the cellar is large, so you can spread a layer of corn stalks under the cellar and put sweet potatoes. If stored indoors, you can lay a layer of wood on the floor and walls and put sweet potatoes to avoid heavy rot due to moisture near the floor and walls.

Although people now grow fewer sweet potatoes, if you want to store them for a long time, you still have to dry them for a few days after harvesting. After the sweet potato is harvested, the water content of the sweet potato will be very large, especially if there is water on the surface, the sweet potato is cut too much water and is particularly easy to rot during storage in the later stage, so the sweet potato must be dried in the sun for a few days after harvesting, especially when the sweet potato is wet when digging the soil, and the sweet potato skin should be dried 1 in the later stage of storage. If the soil is already dry at the time of harvest, harvest in the morning and dry it in the afternoon and store it.

No, if you put it in the sun, it will lose moisture, which is not conducive to storage.

There is no need to dry the sweet potatoes before storage, and if the sweet potatoes are dried, the moisture of the sweet potatoes will be reduced, so that the stored sweet potatoes will taste particularly poor.

If there is a certain amount of moisture on the surface of the sweet potato, it can be sunried, but not for too long, if there is no moisture, it is good to store it directly in a ventilated place.
