A new method of sweet potato storage, a storage method of sweet potato

The new methods of storing large quantities of sweet potatoes are as follows:1.Indoor fresh storage method, the temperature is too low sweet potatoes are easy to freeze, forming a hard core, steaming is not cooked, and cooking is not rotten. The temperature is more than 18 and it is easy to sprout.

2.Keep the room temperature at around 15.

3.Store the sweet potatoes in a breathable wooden crate.

4.During the day, the window should be opened appropriately for ventilation to keep the indoor air fresh, but to prevent cold air from blowing in.

5.The sweet potatoes you buy are dried in the sun for a few hours, and you should handle them with care.

6.After steaming, dry and preserve, and the sweet potatoes are sliced and dried.

7.Sweet potatoes can only be dried for a long time, be careful not to be exposed to rain, and store them in a dry place indoors after drying.

Store in a ventilated and dry place: wrap it in newspaper and put it in a cool place, so that it can be stored for about 3 to 4 weeks. However, before wrapping them in newspaper, you should also spread the sweet potatoes on the newspaper to bask in the sun, and then wrap them for preservation, which can increase the sweetness of the sweet potatoes.

If conditions allow, you can wrap the sweet potatoes in newspaper and put them in the refrigerator crisper so that the sweet potatoes will last longer and will not sprout.

Indoor storage method for storing sweet potatoes: 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 there is no wooden box, a wooden board should be lined up in the place where the sweet potatoes are stacked and against the wall, and something should be covered on the potato pile 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.

First, choose the best sweet potatoes into the cellar.

The storage effect of sweet potatoes is directly related to the quality of sweet potatoes before entering the cellar. Therefore, before entering the cellar, the sweet potatoes should be screened to remove lesions, knife wounds, insect wounds, and more"Swollen soil"Because these sweet potatoes carry germs, it is easy to cause large areas of rotten potatoes in the cellar.

2. Choose the appropriate storage method.

There are roughly two ways to store sweet potatoes, namely high-temperature storage and low-temperature storage. The high-temperature storage method is to heat up the sweet potatoes to 35-38 after they are put into the cellar, and keep them for 2-3 days to kill the black spot and soft rot and other germs of the sweet potatoes. Then reduce the temperature to 10-14 low for storage.

The effect of this method is very good, but the cost is high and the operation is more troublesome, so the low-temperature storage method of pharmaceutical treatment is more suitable for farmers who store separately. Using the low-temperature storage method, the potato cellar is first disinfected one week before the sweet potatoes are put into the cellar. The cellar can be sprayed and disinfected with 70 of Tobuzin 1000 times or 50 of carbendazim 800 times.

Second, after the sweet potato is harvested, it should be processed in time and put into the cellar in time. You can use 70 Tobuzin 1000 times solution, or 50 carbendazim 800 times solution, soak the sweet potatoes in a ratio of 1:1, and then remove the drops and dry them into the cellar.

Third, after the sweet potatoes are put into the cellar, various methods are used to keep the temperature in the cellar below 15 and above 10. The temperature in the cellar is lower than 15, which can inhibit the activity of germs, and higher than 10, which can avoid freezing damage and achieve the purpose of safe storage.

3. Strengthen the management of potato cellars during the storage period.

Sweet potatoes can be divided into three management periods: early winter, overwintering and post-spring. In the early winter (before heavy snowfall) the cellar is warm and humid, so the focus is on cooling and dehumidifying. The first method is to place the bamboo tube in time after the sweet potato is put into the cellar to facilitate ventilation, cooling and dehumidification; Second, when the cellar temperature is higher than 15, the potato cellar should be opened in time to cool down and drain moisture.

When the temperature drops to 10 or below, the cellar should be covered in time to keep the temperature in the cellar between 10-14. During the wintering period (heavy snow to the beginning of spring of the following year), the main work is to keep the temperature in the cellar above 10. Check the temperature of the potato cellar every few days.

If the temperature is found to be below 10, it should be covered with straw in time. After the beginning of spring, the temperature is often cold and hot, and the management of the potato cellar is mainly to strengthen the inspection, adjust the temperature in the potato cellar, so that it continues to be kept between 10-15, and replenish water as appropriate to prevent sweet potato bran.

New ways to store sweet potatoes: Storing sweet potatoes in this way is not bad at all.

How do you say that?

It is also new compared to ancient times.

The method has come out a long time ago, and now it's not all stored in cold storage?

Sweet potato storage method: carton preservation method.

First, we have to choose sweet potatoes, sweet potatoes in the process of harvesting and transportation will inevitably have bumps, these bumps and broken skin of sweet potatoes do not affect the taste, but when preserving, we must pay attention to this kind of sweet potatoes with broken skin and black spots rotten must be picked out to eat first, because such sweet potatoes are perishable, and will pollute other sweet potatoes, affect the storage time of sweet potatoes, don't let "a stinky fish ruin a pot of soup".

Second, drying, after the sweet potato is selected, do not store it directly, but add one more step to dry, the purpose is to dry the moisture on its surface, so that the sweet potato is not easy to spoil and can be stored for a longer time. In addition, dried sweet potatoes will convert a part of the starch into sugar under the action of amylase, so the taste of dried sweet potatoes will be sweeter.

3. Packing, take a carton, first spread a layer of plastic paper at the bottom, then spread a towel on it, and then put the sweet potatoes on the towel one by one, leave a certain gap between the sweet potatoes and the sweet potatoes, do not crowd too full, and do not stack them to avoid bruises, and finally fold the towel to cover the sweet potatoes, seal the carton and put it in a cool place to store it.

Plastic paper has a moisture-proof effect, paper strips and towels have good moisture absorption, can keep the surface of sweet potatoes dry, sweet potatoes want to germinate, need to be temperature and temperature, conditions can not be reached, naturally will not sprout.

Sweet potato selection method:

First: Look at the shape of the sweet potato:

Sweet potatoes come in two shapes, which are lean and slender and round and short. Among them, the thinner sweet potatoes are jokingly called "male sweet potatoes" among the folk, while the short and fat sweet potatoes are called "female sweet potatoes".

The slender shape of the male sweet potato is also very beautiful after cutting, mainly because the sugar content is much higher than that of the "female sweet potato". The "mother sweet potato" is relatively fat, so it is not suitable for baked sweet potatoes, otherwise there will be a situation where the appearance is cooked, but the inside is still raw. "Mother sweet potato" is more suitable for cutting into pieces and boiling sugar water.

Second: Look at the dirt on the surface:

Pick sweet potatoes that are dry to the touch, as this type of sweet potato has been left out for some time since it was unearthed. After a period of drying, the moisture of sweet potatoes will be appropriately reduced, the concentration of sugar will become higher, and the taste will be sweeter. And those sweet potatoes with moist soil on the surface indicate that they have just been unearthed.

Freshly dug sweet potatoes have more water and less sugar, so they don't taste so sweet.

The best way to store sweet potatoes: indoor storage method, slicing and drying, shed storage method, well storage method, etc.

1. Indoor hoarding method

Choose a tightly insulated room, set up fire channels around the base of the wall, and use a stove to provide warmth. Hoards are built on the inside of the house. The height of the stockpile, the width of the rice, and the length depend on the size of the house and the amount of storage.

Hoard bean leaves and soft grass at the bottom and around it. Store healthy and disease-free sweet potatoes in the stockpile. Use measures such as opening and closing doors and windows, extinguishing stoves, and opening lids to meet the needs of safe storage of sweet potatoes.

2. Shed storage method

Dig cellars 2 meters wide, 3-4 meters long and 2 meters deep outdoors. If the groundwater level is high, it can also be dug into a semi-underground type, and the above-ground part is made of soil to beat the wall. The mouth of the cellar is more than 30 cm above the ground.

Wooden sticks are erected on top of the cellar entrance, and 30 centimeters thick straw is spread on the sticks, and the grass is covered with soil meters or more, leaving an entrance and exit in the southeast corner.

3. Well cellar storage method

This method is mostly used in the cold areas of the north. The upper part resembles a well, with a diameter of 1 meter and a depth of 3-5 meters (depending on the degree of cold and warmth). When the depth is decided, then expand the barrel hole on both sides, and dig forward in the horizontal direction, 1 meter wide and 1 meter high.

After digging 1 meter, it was re-excavated into a storage room. The size of the storage room depends on the storage capacity, but it can generally store 250-300 kg of sweet potatoes per cubic meter of space. The bottom of the well needs to be padded with yellow sand.

The wellhead should be 30 cm above the ground. Sweet potatoes can be filled with seventy percent of the storage room. Using the well cellar method, personnel need to pay attention to prevent carbon dioxide suffocation in the well when going down the well.

4. Slice and dry the sweet potato to preserve it

Slice the sweet potatoes and dry them on the house or in a sunny, dry and ventilated place.

Summary. Hello dear, you can build a constant temperature library to preserve sweet potatoes, the constant temperature library has a unique system to regulate the temperature, just control the temperature, to ensure that the temperature of sweet potatoes in the storage process, constant between 10 and 14 degrees, not too low, at the same time to ensure that there is a certain amount of air circulation, to avoid the occurrence of hypoxia caused by sweet potato rot, if the sweet potatoes are relatively few, you can also use cartons to preserve, remove the soil on the surface of the sweet potatoes, be sure not to wash with water, remove the soil on it, and then put the sweet potatoes neatly in the box, After putting the box sealed and preserved, put it in a cool and dark place, this method is very practical, for some dug up sweet potatoes, you can process sweet potatoes into sweet potato flour or sweet potato chips to preserve, sweet potato chips are not only nutritious, but also delicious, sweet potato flour can be made into vermicelli, become a rare delicacy on the table.

Prepare some cardboard boxes, choose a cardboard box with thick paper and a vent next to it. Put the dried sweet potatoes into the carton, and when placing them, pay attention to leaving a certain gap between each sweet potato to prevent the sweet potatoes from being damaged during storage, and the soup will flow to other sweet potatoes to imitate the surrounding sweet potatoes.

After placing a layer of sweet potatoes, sprinkle a layer of not very dry sand, and the sand tells that the soil should completely cover the sweet potatoes. Then, after the call, spread a layer of newspaper, then a layer of sweet potatoes, and then sprinkle in a layer of sand, so that the socks touch layer by layer, and fill the box with sweet potatoes.

After the sweet potato is filled with the box, it is then loaded with an appropriate amount of sand and soil to cap it, and covered with a layer of poor and newspaper or shed toilet paper, which can not only absorb moisture, ensure that the humidity in the carton is appropriate, but also avoid the sweet potatoes from rubbing against each other and breaking the skin.

Seal the carton with tape and store it in a cool and ventilated slag sail at a temperature of 13-16 degrees. Eat and take, the sedan is very convenient, so that the sweet potatoes are stored, the sweeter the sweet potatoes are, and they will not be bad until the next spring. If you are in the countryside, you can find a place where the temperature is about 15 degrees in winter, pile up the sand, and bury the sweet potatoes in the sand for storage.
