What is the reason why sweet potatoes are difficult to store? How to store sweet potatoes so that th

In general, the drier the food, the easier it is to preserve.

The water content of sweet potatoes is too high, generally around 70%, which is why the yield of sweet potatoes is so large.

Potatoes are the same as sweet potatoes for the same reason.

Rice and wheat, which have less water content, are easier to preserve.

Sweet potato growers pay attention, I don't know if you have found it, the storage of sweet potatoes in recent years has been particularly difficult. In fact, the reason is very simple, mainly because the water content of sweet potatoes has increased, and too much moisture is not conducive to the storage of sweet potatoes.

What is the reason why sweet potatoes are difficult to store? How to increase the yield and increase the starch content?

In recent years, the yield of sweet potatoes is very high, after the water content of sweet potatoes increases, the starch content becomes relatively low, which will increase the difficulty of storage. Give you a recipe, which can effectively increase the yield of sweet potatoes and increase the content of sweet potato starch after use. What exactly do you use?

You can use 50-80 grams of potassium dihydrogen phosphate + 50 ml of calcium sugar alcohol + triacosanol. When using triasanol, it must be sprayed according to the method guided by the manufacturer. This recipe can be used after the sweet potato seedlings are sealed, and can be used twice, with an interval of about ten days, and can effectively increase the content of sweet potato starch after use.

When using triasanol, it must be sprayed according to the method guided by the manufacturer. The purpose of using calcium sugar alcohol is to improve the synthesis of the cell wall and the photosynthesis of leaves. The function of potassium dihydrogen phosphate is mainly to supplement potassium, promote the expansion of sweet potatoes, and promote the accumulation of starch dry matter.

What is the reason why sweet potatoes are difficult to store? How to increase the yield and increase the starch content?

This recipe is actually a bit similar to the plant ash we used in the first days, which contains not only potassium but also calcium. If you want to increase the accumulation of dry matter and starch content of sweet potatoes, and improve the quality of sweet potatoes, you can use this recipe, farmers may wish to try it.

What is the reason why sweet potatoes are difficult to store? How to increase the yield and increase the starch content?

The demand for fertilizer in sweet potato planting is large, and supplementing the nutrients required for growth has great nutrients for increasing yield and improving crop quality, especially the demand for potassium fertilizer in the fruit expansion period, and the appropriate supplementation of potassium fertilizer will increase the sweet potato tuber, increase the starch content, and improve the taste. North American Agricultural University focuses on the R&D and production of water-soluble fertilizers, among which water-soluble fertilizers are used in the fruit expansion stage of tuber crops such as sweet potatoes and potatoes, and the effect is very good.

Sweet potatoes are generally not recommended to be refrigerated in the refrigerator.

Although sweet potatoes, potatoes, taro, etc. are all potato foods, they are not stored in the same way. Sweet potatoes and purple potatoes are afraid of low temperatures, and the storage temperature is less than 15 and are easy to be frozen, so they cannot be put in the refrigerator and should be stored in a dry and cool place. Potatoes sprout in a high humidity environment, and it is also recommended to keep them in a cool place at room temperature due to the high humidity in the refrigerator.

There are not too many requirements for storage of yams, taro, etc., put them in bags and put them in the refrigerator.

Several ways to store sweet potatoes::

1. Indoor storage.

Sweet potatoes are afraid of cold, and when the temperature is too low, they will be frozen, forming a hard core, which is not cooked or boiled; If the temperature is too high, it will sprout again, and it is best to control the room temperature at about 15. Sweet potatoes are damp and can easily cause germs to attack and cause rot, so it is best to store them in a breathable wooden box. If you don't have a wooden box, stack the sweet potatoes in a place and against a wall.

Planks should be put on top of the pile, and the pile should be covered with something to prevent moisture. In the warm day, it is necessary to open the window appropriately for ventilation to keep the indoor air fresh, and to prevent cold air from blowing in. Sweet potatoes bought from the market are best left in the sun for a few hours to reduce the moisture of the wound and promote healing.

2. Well cellar storage: choose a place with high terrain, solid soil and low groundwater level, and dig a wellbore downward, generally with a diameter of about 1 meter and a depth of 5 or 6 meters. The size of the storage room can be determined according to the amount of storage.

In the storage room, 10-15 cm thick dry sand should be padded, on which sweet potatoes are placed. Sweet potatoes can only be filled to 70% in order to leave room for ventilation, otherwise they will rot aggravated by humidity and heat.

3. Slice drying and preservation.

Slice the sweet potatoes and dry them on the house or in a sunny, dry and ventilated place. Be careful not to be exposed to rain or snow. After drying, store it in a dry place indoors and soak it in water before eating.

Note: Sweet potatoes should not be kept in the refrigerator.

If stored in the refrigerator, it is easy to become soft due to the moisture in the refrigerator, and it is easy to become perishable due to the moisture in the refrigerator.

Sweet potatoes are softened because the water in the sweet potatoes is lost. Instead of wilting because the sweet potatoes have gone bad. At this time, the nutritional content of sweet potatoes has not changed due to the loss of water, so they can still be eaten.

Of course, if the sweet potato is wilted due to deterioration, then the sweet potato can no longer be eaten for spring.

Sweet potatoes are also seasonal and can be stored for more than 6 months in northern regions. However, if it is stored for too long or improperly, it will cause the loss or deterioration of nutrients, making sweet potatoes inedible. If stored in a humid place, sweet potatoes are very prone to black spot disease, at this time the surface of sweet potatoes is brown, black spots, or rot or potato heart hardens and bitter, not only the nutrition is lost, but also after eating the human liver has a toxic effect, stomach discomfort, nausea and vomiting, abdominal pain and diarrhea, severe can occur high fever, headache, wheezing, hematemesis, delirium, convulsions, coma, and even death.

Usually the sweet potatoes in the countryside will be dried in the sun for a few days before eating, because the newly unearthed sweet potatoes have too much moisture, and they are particularly sweet after being cooked after a few days of drying. So sweet potatoes are much better after wilting than when you first bought them. <>

Extended Materials. Sweet potatoes, also known as sweet potatoes or sweet potatoes, are most popular in autumn, but they are available year-round with high nutritional value. Sweet potatoes are rich in vitamins A and C, as well as carotene, and contain no fat or cholesterol.

Another benefit of sweet potatoes is that they can stay fresh for up to 1 month when stored correctly. Circulating air can cause them to become bitter and hard, so they should be kept in a dark, cool place, such as a pantry (but not a refrigerator).

If not stored properly, sweet potatoes can quickly go bad and show several characteristics of rotting and spoiling.

Check sweet potatoes for signs of rot. Rotten sweet potatoes will appear dark brown spots on the surface or shout to dig holes. Although it is possible to cut off the spoiled spots, the rest of the part will still have a bitter taste.

Touch the skin of the sweet potato with your hands. If the skin is visibly wrinkled and dehydrated, the sweet potato is already spoiled.

See if the sweet potatoes are sprouting or rooting. The new roots are slightly lighter than the old roots, and there is no harm. Growing new roots is a sign that sweet potatoes are spoiling.

Cut the sweet potato and look inside for dark brown spots. Sometimes it is difficult to see these spots from the outside. If there are spots on the inside, it also means that the sweet potato has spoiled.

Do the following:

I said that it used to be the main food in the countryside, at that time there was not much white flour, because the yield of sweet potatoes is high, and the requirements for the field are not high, so the planting is more, I remember when I was a child, every family has a cellar, and after winter, these sweet potatoes will be put in the cellar, which can be put for a long time and will not be broken, if you want to eat, you can go in and get it at any time, today I will teach you a method of storing sweet potatoes, I hope you can use it in the future.

In winter, the family generally prepares some sweet potatoes, because the sweet potatoes at this time are relatively cheap, that is, they can not only be boiled and eaten, but also boiled and drunk, the nutritional value of sweet potatoes is also very high, but they dare not buy too much at one time, if they buy too much, it is easy to break, generally everyone touches the handguard inside the carton, so that it can not be stored for too long, in fact, as long as you add 2 more steps.

The first step is to buy fresh sweet potatoes, directly put them on the balcony and expose them to the sun for about five days, because there is a lot of moisture in the fresh sweet potatoes, so that after the exposure, the moisture in it will be much less, I said that it is not easy to spoil, and after the sun exposure, after the sugar powder in it precipitates, you say that it tastes sweeter.

The second step is to put the sweet potatoes into the carton, put a layer of newspaper on it, which can absorb the excess water in the sweet potatoes, and then cover the newspaper with a layer of thatch, seal it, and put it in a cool and dry place, which will not spoil for a year.

1. Cellar preservation. After the sweet potatoes are harvested, they are dried in the sun for 4 days, and about 10 cm of dry sand is spread under the cellar, and the sweet potatoes are packed into the cellar, with a maximum of 7 layers full, leaving room for ventilation.

2. Indoor storage. You can put sweet potatoes in a sealed balcony or the like, find a wooden box or cardboard box, put some wooden boards on the corner of the wall, put the wooden box or cardboard box on it, lay some dry straw at the bottom of the box, put the sweet potatoes in, the temperature is lower than 15 degrees Celsius is to spread something to keep warm, the weather is good, the temperature is high, and when the sun is out, open the box, ventilate it, and it can be stored for a long time.

3. Fresh-keeping storage. The most scientific preservation method is to keep the fresh storage, the fresh storage can artificially regulate the humidity and temperature of the environment, so if the amount of sweet potatoes is large, you can build a fresh storage to maintain the temperature at 12 to 14 degrees Celsius, and the humidity is about 90%, which is the most suitable temperature for sweet potato storage.

4. Shed storage. Generally, dig a cellar about 2 meters wide, 3 4 meters long, and about 2 meters deep. Stack the sweet potatoes from the bottom up one by one, and avoid direct contact between the sweet potatoes and the cellar wall.

5. Cellar storage. The structure of the cellar is similar to that of ordinary houses, but the walls and roof are thick, sealed on all sides, the windows are open, and there are fire channels for heating, which can be treated with high temperature callus. There are two types of cellars: large cellars (storage of 15,000 kilograms) and cottage cellars.

The cellar body of the hut cellar is small, labor-saving and material-saving, suitable for farmers' storage, generally each cellar can store 1500 3000 kg.

1. Carton storage method.

In fact, the carton preservation method is a very convenient and feasible method for many friends, and we generally buy a box of fruit or milk, drinks, etc., which will have a large carton. At this time, we don't throw away the carton directly, but keep it to preserve the sweet potatoes we buy more, which is actually very useful. When storing sweet potatoes, we all need to dry the sweet potatoes, and then we use paper to preserve the sweet potatoes, leave a certain distance for each sweet potato to place, and then put the carton directly in the shade.

2. Soil preservation methods.

Using this method of preservation is equivalent to preserving sweet potatoes in a cool and dry environment, and sweet potatoes themselves are grown in the soil, and this method of preserving sweet potatoes will make sweet potatoes last for a long time.

3. Refrigerated storage method.

If we want to preserve sweet potatoes by refrigerating them, we choose to wrap them in paper towels and then use a tighter plastic bag with a pull strip to preserve the sweet potatoes. This method of preservation is very suitable for us to preserve sweet potatoes at home, and it is similar to the environment in which sweet potatoes are stored in the cellar, so the method of refrigerating and preserving sweet potatoes is very practical. Sweet potatoes can be stored in a cool, dry place.

There are more ways to make sweet potatoes and steamed sweet potatoes. These two methods are the best way to preserve the original flavor of sweet potatoes. In addition to that, you can also fry it.

It is to peel the sweet potato, slice the sweet potato, and then fry it in oil to make delicious sweet potato chips. It is also okay to peel sweet potatoes and eat them directly. Store at room temperature or in the refrigerator.

If you want to store sweet potatoes for a short time, you can place them directly in a cool, ventilated and dry place, which can be stored for about seven days, but should not be stored for a long time, because sweet potatoes are easy to germinate at room temperature. If you want to store it for a long time, you can put it in a plastic bag and put it in the refrigerator, and seal it in a plastic bag to prevent it from losing moisture due to long-term storage.
