Yam is rich in nutrients, what are the tips for preserving yams?

Yam is one of the most common ingredients, and the yam harvest usually begins in October every year. Yam nutrition is also very rich, many people like to eat yam in daily life, and the practice of yam is also very much, both the elderly and children can eat more yam, the benefits to the body are very obvious. However, in real life, many people may be more distressed, if they buy too many yams at one time, they don't know how to store them.

01. Refrigerated yam is a kind of crop that grows underground, generally if it grows in the countryside, after we dig out the yam from the ground, we can remove some of the soil on the surface of the yam, and then dry the moisture on the surface of the yam slightly. Then we can put the yam in a bag and put it directly in the refrigerator to store, for example, a rural cellar is a very good choice, and it can be kept fresh for at least a few months in the cellar. If you don't have a cellar, you can put it in the refrigerator.

02. If the ventilation is in a relatively cool and ventilated environment, the yam can also be stored for a period of time, but this time will not be too long. For those merchants who sell yams, they usually use this method to keep them fresh, because it won't be long before their yams will be **, so it is obviously not appropriate to use the refrigeration method. We can store the yam separately in a more ventilated place, and be sure to ensure that it is dry, and it is not a big problem to store it for about 10 days.

03. Soaking is actually a very good storage method, in the process of picking crude drugs, some yams may be broken. And there is no way to eat these broken yams quickly, so we can use this method to store them at this time. We wash these broken yams, then soak them in rice wine for a while, then use a hair dryer to blow the broken wounds, and store them directly in a cool place in the corner of the wall, which can usually be stored for several months.

First of all, it should be placed in a relatively cool place, and it can also be directly put into the refrigerator, and then the sun should not be too long, the temperature must be between 18 degrees and 20 degrees, and then it can also be placed directly in the basement.

The most commonly used preservation method of yam is low temperature preservation, generally before low temperature storage, it should be placed in a sunny place to see the light, and the surface moisture should be dried. Store in a cool and ventilated place.

Yam is a common home-cooked delicacy. To store yams, you need to store them in a cool, dry place. In addition, you can add yam and wrap it in plastic wrap.

The preservation tip is to be sure to keep it in a cool and ventilated place, and if it is cooked, be sure to put it in the refrigerator for preservation.

It can be stored in the cellar, and at the same time pay attention to ventilation, it can also be placed in cold storage, and the more humid and cold places are suitable for yam preservation.

Yam is rich in nutrients, containing protein grams, carbohydrate grams, calcium 14 mg, phosphorus 42 mg, iron mg, carotene mg, thiamine mg, riboflavin mg, niacin mg, ascorbic acid 4 mg per 10o grams. In addition, there are nutrients such as protein, amino acids, and polyphenol oxidase. It has the effect of inducing the production of interferon and enhancing the body's immune function.

Yam contains only about half of the calories and carbohydrates of sweet potatoes of the same quality, contains no fat, and has a higher protein content than sweet potatoes. The main ingredient of yam is starch, part of which can be converted into dextrin, the decomposition product of starch, which can help digestion, so yam is a taro food that can be eaten raw. Yam contains a variety of trace elements, among which the content of potassium is higher, the types and quantities of vitamins contained are smaller, and there are almost no carotene.

The leaves of yam are excellent for carotene**, and good for calcium, iron, and vitamin C**.

When preserving yams, in fact, it is to keep the yams in a dry and cool environment, and the old farmers said that they usually put the yams in the cellar, so that the yams can be stored in a low temperature environment, and the yams can be kept for several months. But if we put yams at home, we don't have a cellar environment. In fact, yam, like potatoes that grow in the ground, needs to be stored in a dry environment, and if you put it in the refrigerator, it will accelerate the speed of yam sprouts.

After buying the yam, peel and cut the yam into pieces, divide it into plastic bags according to the amount of each consumption, and immediately put it in the upper layer of the refrigerator for rapid freezing. The yam should be soaked in salt water immediately after slicing to prevent oxidation and blackening. When fresh yam is cut, there will be mucus, which is easy to hurt the hand, so you can wash it with water and a little vinegar first, which can reduce the mucus.

When eating, when the water boils, it can be directly put into the pot without thawing, which is convenient and can ensure the quality of the yam. Fresh yam generally has a smooth skin and a natural color. If you need to store it for a long time, you should put it in wood sawdust to bury, and if you want to store it for a short time, you only need to wrap it in paper and put it in a cold and dark place.

If you buy cut yam, avoid contact with the air and wrap it in a plastic bag and put it in the refrigerator. Chopped yams can also be frozen in the refrigerator. The peeled yam is very slippery and can be handled with something like vinegar or salt on your hands.

Yam is particularly nutritious, it is not high in calories, high in vitamin B, magnesium, fiber, potassium. It is a vegetable that is used both for medicine and food. It has the effect of nourishing qi, strengthening the spleen and stopping diarrhea, nourishing yin and moisturizing dryness.

When preserving yams, you can put the yams in the cellar, and then sprinkle more lime in the corner of the cellar, or you can put them in the refrigerator for refrigeration, or you can put them in a cooler place, and when preserving, you must ensure that the skin of the yam is not damaged, so that it can be stored for a long time.

When the yam is stored, it should be placed in a ventilated and cool place, avoiding moisture. Do not seal when storing. Do not put in the refrigerator either. At the same time, it is necessary to avoid direct sunlight and exposure.

Put it in a cool and ventilated place, do not let the cut surface oxidize, you can wrap it in plastic wrap, put it in the refrigerator, or soak it in rice wine.

The shelf life of yam is between 3-6 months. It can be stored refrigerated, in order to maintain the taste, it is best to store it with skin, and do not wash the soil on the iron stick yam, and then wash it when eating to maintain its original flavor to the greatest extent, just wrap it in plastic wrap or put it in a sealed bag. Yams are dense and strong, so they are stored in a ventilated place at room temperature.

The broken yam is easy to oxidize with the oxygen in the air, resulting in the deterioration of the cross-section; After the yam is broken, you can soak it in rice wine first, then dry it with a hair dryer, wrap it, and put it in a cool corner of the wall to keep it for several months.

Short-term storage of yams1. After peeling and cutting the yam into pieces, divide it into plastic bags according to the amount of each consumption, and immediately put it on the upper layer of the refrigerator for rapid freezing.

2. There is no need to defrost when cooking, and it is convenient to put the yam in the pot immediately after the water boils, which is convenient and can ensure the quality of the yam.

3. Yams, like apples, are rich in iron, and browning is normal after cutting, so they can be eaten with peace of mind.

[The first trick, storage at room temperature].

Now that it has entered winter, the temperature is generally relatively low, so we can keep the yam at room temperature, but there is a prerequisite, that is, to ensure that it is protected from light. Because an important factor in the growth of yam sprouts is light.

The specific method is to put the yam into a non-woven bag with good air permeability and put it in a cool and ventilated place. Be careful not to use non-breathable plastic bags or other tools with good seals, as yams will respire and produce moisture, making them in a humid environment and perishable. Of course, we can also wrap the yam in newspaper or absorbent paper, and then put it in a dark bag and seal it.

The second trick, refrigeration preservation].

Low temperature can prolong the storage time of yam, according to statistics, in an environment of 4-10 degrees, yam can be left for up to a year. Therefore, if it is a relatively small amount of yam, it is still good to put it in the refrigerator and keep it cold.

The specific method is to wrap the yam in absorbent paper, then put it into a plastic bag, squeeze out the air inside, and tie the bag tightly. Store in the refrigerator.

Two things to note].

1. The yams on the market are relatively long, and if you want to put them in the refrigerator, you may have to break them to put them down, so you need to pay attention to the fact that the broken wound is easy to mold, and we need to soak it in white wine and then dry it thoroughly to avoid moldy wounds.

2. The first two tricks are when preserving yams, do not wash or peel them, it is best to have soil on the surface, pay attention to the preservation of yams, which is a natural barrier.

The third trick, freezing method].

If you have a freezer at home, then we can also put the yam in the freezer and freeze it for preservation. The specific method is to wash and peel the yam that needs to be preserved, cut it into slices or segments according to your own needs, and then pack them into a fresh-keeping bag according to the amount of food you eat, seal it and freeze it for preservation.

The yam preserved in this way is very convenient when eating, take out a bag before, do not need to thaw, directly put it in the pot, or fry or make soup, you choose, it tastes no different from fresh yam.

It is usually placed in a ventilated and dry place to prevent moths.

There are also the following methods:

1. Room temperature ventilation preservation method: the density of authentic Wenxian iron stick yam is extremely high, and the fresh goods are very strong, because the soil structure of the Jiaozuo Huai medicine production area in Henan Province is relatively special, so the yam that grows is also very strong and tough.

And after cooking, the taste is dry, noodles, sweet, and glutinous, and it will not fall apart after cooking for a long time. Because of the high density and firmness of fresh goods, it can be stored in a ventilated place at room temperature and can generally be stored for 3-6 months without a problem, and it is usually placed in a dark place on the balcony.

Precautions: Do not use plastic bags to contain iron rod yams, which will not have good air permeability; Do not wrap iron stick yams in newspapers, as the lead in the newspaper will penetrate deep into the yams and be bad for health; It can be wrapped in a napkin and stored in a cool, dry place with a ventilated area.

2. Rice wine soaking method: The iron stick yam we buy in the market is usually not complete, because after the iron stick yam is dug out of the ground, the growers have to cut off the "stump" for the next planting time to do seeds. In order to preserve the yam after the "halter" has been removed for a long time, growers usually soak the cross-section of the yam with rice wine.

This is because fresh yam is prone to oxidation with oxygen in the air, and we can also refer to this method when storing it at home. For yams that are not eaten for the time being after being broken, soak them in rice wine through the incision, then dry them with a hair dryer to promote wound healing, wrap them in a napkin, and store them in a cool corner for several months.

Precautions: Freshly dug new yam tends to have more moisture, the surface will be slightly wet, if you want to preserve this yam need to dry on the balcony before putting it away, but do not let direct sunlight or bake.

3. Refrigerator refrigeration method: Studies have shown that fresh iron stick yam can be stored for 3 years at 1-4 degrees. If you have enough space in your refrigerator, you can refrigerate yams that you don't eat for a while.

In order to maintain the taste, it is best to store it with the skin, and do not wash the soil on the yam, and when you eat it, you can wash it to maintain the original flavor to the greatest extent, just wrap it in plastic wrap or put it in a sealed bag.

Precautions: It is best to separate yam from the fruit, because the fruit will release ethylene during the slow ripening process at low temperature, which will cause the yam to grow faster and deteriorate.

4. Cold storage preservation methodThis method is suitable for large-scale storage of iron stick yams. Jiaozuo four big medicine network of iron stick yam warehouse is a constant temperature warehouse, the warehouse temperature is 2 to 6 degrees all year round, after the planting base of the iron stick yam unearthed, we will be transported to the constant temperature warehouse in time, so as to ensure that customers and friends can buy authentic iron stick yam from us all year round.

5. Cutting and freezing method: For friends who do not have enough refrigeration space in the refrigerator, it is also a good choice to use the method of cutting and freezing to preserve iron stick yams. You can peel and cut the yam into pieces according to the approximate amount of each time with a plastic bag, and then put it in the freezer drawer to freeze quickly, there is no need to thaw when eating, and the water can be boiled before it can be put into the pot, so as to ensure that the nutrients of the iron stick yam are not lost.

Precautions: Yams, like apples, are rich in iron, so browning will occur after cutting, which will not affect the quality of yams, so you can eat them with peace of mind.

There are four common ways to preserve yams.

The principle is to build a burial pit about 1 meter high with bricks on the cement floor of the warehouse, and then spread about 10 cm thick and sun-sterilized dry fine mud or dry yellow sand at the bottom of the pit, and then put the yam that has been selected and dried on the sediment in order, and a layer of yam and a layer of sediment are piled up, and finally sealed with dry fine mud or yellow sand. After burial, it usually takes about 1 month to take a sample to check whether there are any lesions in the yam. If a lesion is found, it should be removed in time to prevent spread.

2.Trench Tibetan method.

The trench method is to dig a trench first and then bury it. When digging a trench, a trench 1 m wide and 1 2 m deep should be dug. When the yam vine on the ground dies, the yam can be harvested and buried in a ditch.

Usually, a layer of yam is layered with wet soil, and they are arranged neatly, and finally a layer of wet fine soil is covered on top, and the soil is gradually covered as the temperature drops. The ditch storage method can be used to store yam until April of the second year.

3.Refrigeration.

Yam growers can also build cold storage for preservation, which is also a better way to preserve yams. First of all, the selected dried yam is packed in the cold storage and stacked or placed on the storage shelf, the temperature is controlled at 1 5, and the relative humidity is 80% 85%. Attention should be paid to ventilation during refrigeration, so that the yam can maintain life activities during storage, reduce water loss and prevent changes in taste.

4.Basket Tibetan method.

When using this method to store yam, it should be paved at the bottom of the sterilized basket or box and around with sun-sterilized straw or wheat straw, and then the selected yam should be piled up layer by layer until it is almost full, and then covered with wheat straw to the basket or box mouth, and then stacked in the warehouse by horseback riding, and the height is generally 3 wicker baskets or 4 crates high. This method should prevent the influence of ground moisture on the tubers, and when stacking piles, bricks or planks can be placed under the basket or box to leave a distance of about 10 cm from the ground.
