Do freshly dug sweet potatoes need to be sun dried, and should freshly dug sweet potatoes be dried a

After the sweet potatoes are harvested, they still have to be dried for a few days before they can be stored. After harvesting, the moisture content of sweet potatoes will be very large, especially the surface moisture, sweet potatoes contain too much water and are particularly perishable in the later storage, so after harvesting sweet potatoes, they must be dried in the sun for a few days, especially when planing sweet potatoes, the soil is relatively moist, and the skin of the sweet potatoes should be dried slightly wilted before storage. If the soil is already dry at the time of harvest, it can be harvested in the morning and stored in the sun in the afternoon.

Freshly shaved sweet potatoes need to be dried, and drying them for a few days will both extend the storage time and make them sweeter.

Extended Materials. How to pick sweet potatoes.

1. Choosing sweet potatoes is different from other vegetables, and the freshly unearthed sweet potatoes generally have a higher water content, so the fresh sweet potatoes are not sweet enough. Generally in rural areas, sweet potatoes are dug out, and then continue to be placed on the roof to dry for a few days, while drying the soil, but also drying the water in the sweet potatoes, so that the drier sweet potatoes will be sweeter than when they are fresh, whether they are steamed or roasted. So when you choose sweet potatoes, you can pinch the sweet potatoes with your hands, if the sweet potatoes are a little soft, the skin has a slight wrinkles, not particularly hard, that is, the sweet potatoes that have been relatively dry, such sweet potatoes can be washed and steamed directly after taking them home, and they will be particularly sweet!

If it is too fresh sweet potato, it is also recommended that you buy it and put it on the balcony to dry it for a few days before eating, and the taste will be better.

2. Choose sweet potatoes that are easy to preserve:

To see the skin of a sweet potato. Some sweet potatoes have been rubbed and broken, in fact, such a small damage is harmless, but it is necessary to check whether the sweet potato has insect eyes, if the sweet potatoes have insect eyes, then no matter how they are cooked, there will be a particularly unpleasant smell after cooking. It will even smoke other good sweet potatoes along with it.

Therefore, when choosing sweet potatoes, the first thing to check is whether the sweet potatoes have insect eyes, and the sweet potatoes without insect eyes are sweet sweet potatoes.

In addition, sweet potatoes are generally sweeter and sweeter, and they can be stored in a cool and dry place for a few days after they are bought, and when the sugar in the sweet potatoes is fully accumulated, they will be extra sweet after cooking.

First of all, it is confirmed that the storage of agricultural products has its own characteristics. Regarding your question, I personally feel that it should be possible to dry. In order to reduce moisture, increase palatability, and facilitate storage.

It can be dried to increase the sweetness.

After digging out, let the sweet potatoes dry in the ground for an hour, and the mud will be easily wiped off the sweet potatoes after being dried in the sun.

Early- and medium-maturing sweet potato varieties are harvested at the end of August and early September, and late-maturing varieties are harvested in mid-October. The latest harvest is before the frost. Rainy harvesting is prohibited.

When harvesting, it is necessary to dig, load, transport and unload lightly to prevent the potato peel and potato pieces from being bruised. The storage temperature is required to be 10-15, the relative humidity of the air is 85%-90, and the storage place should be clean and hygienic, and the rodent and poison prevention work should be done. At the same time, it is necessary to have heat preservation measures to prevent frostbite and squeezing, and pay attention to ventilation and heat dissipation.

Sweet potatoes will not be sunburned when placed in the sun, but pay attention to the time and method of drying. If it is cut into slices and dried, it will be fine to dry for about 3 to 4 days. If the whole sweet potato is dried, it needs to be dried for about 5 days before the sweet potato can be dried.

After the sweet potato is dried, it will be more shelf-stable and can enhance the taste of the sweet potato. Sweet potatoes contain a lot of starch and water, the sugar content is not particularly much, just dig out and eat, naturally not too sweet, after a period of time, the water slowly evaporates and decreases, the concentration of sugar increases, it will become sweeter and sweeter.

When sweet potatoes are exposed to sunlight, the starch will be affected by the water to form maltose, which will make the sweet potatoes sweeter. Friends who like to eat sweet potatoes can first place the sweet potatoes in the sun to dry for a few days, and the steamed sweet potatoes will taste better. Sweet potatoes are not only rich in sugar, but also in nutrients such as fiber and vitamins.

Sweet potatoes can be eaten not only steamed, boiled, and roasted. Although the nutritional value of sweet potatoes is very high, sweet potatoes should not be eaten too much, because sweet potatoes contain an oxidase, which reacts in the gastrointestinal tract to produce carbon dioxide, so bloating, burping and other conditions will occur after eating too much.

Fresh sweet potatoes can be sunbathed.

Sweet potatoes that have just been dug out of the ground will be moist, and basking in the sun can allow the moisture on the surface to dry quickly, preventing the sweet potatoes from becoming damp and moldy.

And the freshly dug sweet potato will have less sugar in it, and it will contain more water and starch, and after basking in the sun, the moisture in it will be reduced, and the starch will be converted into sugar, and the taste will become sweeter.

Note that the time of drying sweet potatoes should not be too long, and do not expose them to the sun for a long time, otherwise it will be easy to lose the moisture in the sweet potatoes, the sweet potatoes will become dry, and the taste will be easy to deteriorate.

Although there are fewer sweet potatoes planted now, if you want to store sweet potatoes for a long time, you still have to dry them for a few days after harvesting before you can store them. After harvesting, the water content of sweet potatoes will be very large, especially the moisture on the surface, sweet potatoes contain too much water in the later storage, especially perishable, so after harvesting sweet potatoes, they must be dried in the sun for a few days, especially when shaving sweet potatoes, the soil layer is more humid, and the skin of the sweet potatoes should be slightly wilted before storage. If the soil layer is already very dry at the time of harvest, it can be harvested in the morning and stored in the afternoon.

If the soil layer is too wet, the seedlings should be cut and dried first, and then harvested when the soil layer is slightly dry. When harvesting sweet potatoes, it is best to harvest the seedlings in the morning, harvest them in the morning on a sunny day, and put the potato pieces in the cellar in the afternoon after drying in the ground to prevent frost damage. Sweet potatoes must be moderately dried before storage, which can volatilize a part of the water and improve storage resistance, and at the same time it is also conducive to the soil in the potato pieces to fall, and it is very easy to pick out diseased potatoes, insect potatoes, rotten potatoes, etc.

However, the drying time should not be too long, and it is generally in the cellar on the day of harvest.

If the harvested sweet potatoes are dried, the moisture content of the stems drops sharply, resulting in the nutrients in the stems cannot be reasonably converted, and the parts with less nutrients and more water will rot and are not easy to store. Storing stems, after all, is not drying potatoes, it is unlikely to dry all the water, because the purpose of storing sweet potatoes is to ensure the freshness of sweet potatoes. Sweet potatoes contain sugar and tapioca starch, which not only brings food crops to everyone, but also the origin of key raw materials in industrial production and medicine"。

With the development of social economy, sweet potatoes have evolved into nutritional health products and concentrate feed for livestock with pure belly in the past, and rattan used to make green manure crops has now become a special food for people's health and concentrate feed for raising livestock and marine fish. Therefore, sweet potato planting is a new agricultural project that plays a pivotal role in our grain crop cultivated land, and it has been planted until now, and its planting and utilization value is particularly large.

You can dry it for a while, not dry. Dry the water first and then store it, which is more resistant to storage and is not easy to grow bacteria. When drying the water, be careful not to make the soil on the surface of the sweet potato too clean, and leave some soil on it, which has a protective effect on the sweet potato.

Because after the sweet potato is dug back, if it is dried in the sun or the like, it will lose a lot of water, so you only need to pile it up in some shade and avoid light.

If the sweet potatoes are harvested in normal dry weather, they do not need to be dried, because drying them before storage will make the sweet potatoes lose more moisture, which is not conducive to storage. If the sweet potatoes are harvested in more extreme waterlogging weather, they should be dried, and the soil should be desoiled in the morning when there is dew after the soil is dry, so that the stored sweet potatoes can prevent the loss of too much water.

After the rural sweet potatoes are planed out, they must be dried before storage, and I recommend drying them for a longer time to make the sweet potatoes dry enough before preservation.

Generally speaking, sweet potatoes must be dried when they are planed, otherwise they cannot be preserved, and many farmers do not have this experience, resulting in all the sweet potatoes in a cellar being spoiled. It's a pity that I don't eat it when I feed it to pigs. Sweet potatoes must be dried after they are shaved out for three reasons:

Sieve off the surface moisture to prevent mold, sunburn the eggs of the epidermis to prevent worms, and reduce the metabolic rate of sweet potatoes is conducive to long-term preservation. Here's a closer look at these points:

1. Sweet potatoes should be dried before storage to prevent mold: we all know that if the surface of the crop is moist and has moisture, it is easy for mold to adhere and become moldy. When the sweet potato is planed out, because it grows underground, the surface of the newly planed out is very wet, and there is soil attached to it to keep it moisturized, so if it is stored directly at this time, it will definitely be infected by mold, resulting in mildew.

The author suggests that it should be placed in an open space to dry until the surface water vapor evaporates, and the surface soil falls off after drying, and then collects and preserves.

2. Sweet potatoes should be dried before storage to eliminate surface eggs: many agricultural pests lay eggs in the soil, especially on the surface of the fruit, in order to incubate small insects to eat the fruit. Based on this, as soon as the sweet potato is dug out, it is very likely that insect eggs are attached to the surface, and if it is stored directly, coupled with a humid environment, the small insects will hatch.

Therefore, it must be dried before storage to dehydrate and dry the eggs, so that the eggs can die completely.

3. Sweet potatoes should be dried before storage in order to preserve sweet potatoes for a long time: because the metabolic rate of sweet potatoes is positively correlated with the amount of water in them, the metabolism of water will be vigorous, and the fruit will decompose and germinate. In order to avoid this situation and achieve long-term storage of sweet potatoes, it is necessary to reduce the moisture content of sweet potatoes.

Therefore, the author suggests that it must be dried before storage, and the skin of the sweet potato can be dried and wrinkled, and the moisture in the sweet potato will be greatly reduced, and it can be stored for a long time.

I think it needs to be dried, because after drying, it can make the sweet potato have a longer shelf life; First of all, after the sweet potatoes are bought, we can carry out intensive drying. It should not be too long when drying, otherwise it will take away all the moisture.

Under normal circumstances, it does not need to be sun-dried, but if it is very wet, the soil cannot fall off normally, so it is easy to rot, so it is better to dry it a little or let it cool and dry.

It needs to be dried, which is done for better storage, and you must pay attention to the temperature when storing, and do not put it in too cold places.

Dry. For storage. Be sure to pay attention to the temperature when storing and do not place in a place that is too cold.
