How to preserve fresh yam

Question 1: Several storage methods of fresh yam 1. Ventilation storage method at room temperature: Authentic wen county Tiegun Yam has a very high density and a strong flavor. Due to the special soil structure of Huaiyao producing area in Jiaozuo, Henan Province, the cultivated yam is also very strong and resilient. Moreover, after cooking, the taste is dry, smooth, sweet and glutinous, and it will not be cooked for a long time. It is precisely because of the high density and good firmness of fresh goods that they can be stored in a ventilated place at room temperature, usually for 3-6 months, usually in a place where the balcony is protected from light. Precautions: Do not put iron yam in plastic bags, which is airtight; Don't wrap iron yam in newspaper, because the lead in newspaper will go deep into yam and be harmful to health. It can be wrapped in a napkin and stored in a ventilated, cool and dry place. 2. Rice wine soaking method: The iron stick yam we bought in the market is usually incomplete, because after the iron stick yam is dug out of the ground, the grower has to cut off the "taro" for the next planting. In order to preserve yam without a "halter" for a long time, growers usually soak the cross section of yam with rice wine. This is because fresh yam is easily oxidized by oxygen in the air, and we can also refer to this method when raising it at home. The yam, which is temporarily inedible after being broken, is soaked in rice wine at the incision and then dried by a hair dryer to promote wound healing. After being wrapped in a napkin, it can be kept in a cool corner for several months. Note: Newly dug yam is often steaming, and the surface will be slightly wet. If you want to keep this yam, you need to dry it on the balcony before putting it away, but don't let it go, let it be exposed to direct sunlight or baked. 3. Cold storage method: The research shows that fresh iron stick yam can be stored for 3 years at 1-4℃. If your refrigerator has enough cold storage space, you can keep the yam you don't eat for the time being. In order to keep the taste, it is best to keep it with skin, and don't wash the soil off the yam. When eating, you can keep the original flavor to the greatest extent, just wrap it in plastic wrap or put it in a sealed bag. Note: It is best to separate yam from fruit, because the fruit will release ethylene in the process of slow ripening at low temperature, which will lead to the accelerated growth and deterioration of yam. 4. Cold storage method This method is suitable for large-scale storage of iron stick yam. The iron bar yam warehouse of Jiaozuo Sihuai drug network is a constant temperature warehouse, and the temperature of the warehouse is 2 to 6 degrees all the year round. After the iron stick yam is unearthed from the planting base, we will deliver it to the constant temperature warehouse in time to ensure that our customers and friends can buy authentic iron stick yam from us all year round. 5. Blocking freezing method: It is also a good choice to save Tieshan medicine by blocking freezing method for friends who have insufficient refrigeration space in the refrigerator. Yam can be peeled and cut into pieces, then packed in plastic bags according to the approximate consumption each time, and then frozen in a freezer drawer. You don't need to thaw when eating, just boil the water to ensure that the nutrients of the iron stick yam are not lost. Note: Yam, like apple, is rich in iron, and it will turn brown after being cut, which will not affect the quality of yam and can be eaten with peace of mind.

Question 2: How to keep fresh yam fresh? Fresh yam is slightly treated and stored for 6-8 months;

(1) Pre-dug pit for storing fresh yam indoors, with a depth of 0. 8 ~ 1m, the width and width are determined by the storage of fresh yam, and the surrounding walls and bottom of the pit are insulated with plastic film to prevent moisture.

(2) The yam is dug, that is, the yam is cut into seed potatoes, and the incision is dipped in lime powder for sterilization and antisepsis. Put the top of yam in a vertical pit, sprinkle some fine soil between yam, and cover yam with hay or cotton blanket to keep warm. Find the terminal bud of Chinese yam every 10 ~ 15, and then wipe the bud, which avoids consumption and maintenance and reduces the quality.

Question 3: How to keep yam fresh, ventilated, cool and dry: yam is dense and firm, and can be stored in a ventilated place at room temperature. Generally it can be stored for 3-4 months in autumn and winter. If it is hot in summer, it is best to eat it within two months to prevent germination or deterioration.

1, don't store yam in plastic bags, it's airtight;

2. Don't save yam with newspaper. The lead in the newspaper will penetrate into the yam, which is not good for your health.

3, can be wrapped in a napkin and stored in a ventilated, cool and dry place.

Refrigerator refrigeration

Operation method:

1, yam soil remains original;

2. Wrap the plastic wrap or put it in a sealed bag; 3. Refrigerator temperature 1-4 degrees;

Yam 1 1-65438+ was excavated in February. It is recommended that students who like to eat yam stock up before the year, and it is not recommended to buy them in July and August, because these yams have been 9 months old.

Look at the beard hair, the more beard hair of the same variety of yam, the better. The more hairs yam has, the better its taste, and the more polysaccharides yam has, the better its nutrition.

Question 4: How long can fresh yam be preserved in sand? It can be preserved for a long time. This is how my mother put a bucket of sand and put yam in the sand!

Question 5: How to preserve iron-core yam? 1. Storage method at room temperature, ventilation and shade.

Authentic Jiaozuo iron stick yam has a dense texture and a strong sense of freshness. (Otherwise, how can it be called iron stick yam? ) Due to the special soil structure of Tiegun yam producing area in Jiaozuo, Henan Province, the cultivated yam is also very strong and elastic. Moreover, after cooking, the taste is dry, smooth, sweet and glutinous, and it will not be cooked for a long time. Because yam is dense and strong, it can be stored in a ventilated place at room temperature. Generally it can be stored for 3-4 months in autumn and winter. If the weather is hot in summer, it is best to eat it within two months to prevent germination or deterioration.

Tip: don't store iron yam in plastic bags, which is airtight; Don't use newspapers to keep iron yam. The lead in the newspaper will penetrate into the yam, which is harmful to the health. It can be wrapped in a napkin and stored in a ventilated, cool and dry place.

Second, yellow rice wine soaking slicing method

All the yams we bought in the market are without halters. In Jiaozuo, Henan Province, in order to preserve the iron stick yam after removing the "halter" for a long time, growers usually soak the nodes (or segments) of yam with rice wine. This is because fresh iron stick yam is easy to oxidize with oxygen in the air, resulting in cross-sectional deterioration. We can also refer to this method when raising at home. For example, iron yam that has not been eaten for a while can be soaked in rice wine, then dried by a hair dryer, wrapped and stored in a cool corner for several months.

Tip: Fresh iron yam just dug out will have a slightly wet surface because of its strong steam. If you want to preserve this yam, you need to dry it on the balcony before putting it away, but don't let it go, let it be exposed to direct sunlight or baked. Be sure to put it in a cool and ventilated place.

Third, the refrigerator preservation method

Scientific research shows that fresh iron stick yam can be preserved for 3 years at 1-4 degrees. If there is enough cold storage space in your refrigerator, you can keep the iron bar yam you won't eat for the time being. In order to keep the taste, it is best to keep it with skin, and don't wash the soil off the iron stick yam. Wash it when you eat it to keep its original flavor to the greatest extent, and just wrap it in plastic wrap or put it in a sealed bag.

Tip: Iron stick yam is best separated from fruit, because fruit will release ethylene during slow ripening at low temperature, which will lead to accelerated growth and deterioration of yam.

Four, the cold storage method

Cold storage method is suitable for large-scale preservation of iron stick yam. The iron stick yam warehouse is actually a constant temperature warehouse, and the temperature of the warehouse is 2 to 6 degrees all the year round. After the iron stick yam is unearthed from Jiaozuo planting base in Henan Province, it will be transported to the cold storage in time to ensure that customers and friends can buy authentic iron stick yam all year round. This is mainly suitable for growers in Jiaozuo, Henan, or friends who are engaged in the wholesale and retail of iron stick yam everywhere.

Generally speaking, the storage environment of iron stick yam should be dry, ventilated, dark and cool. No matter how you do this, you don't have to worry about how to keep the iron stick yam. Don't forget to tell your friends around you ~ ~

Question 6: How to store yam in winter? Yam is a kind of storable vegetable with physiological dormancy period. It also has the characteristics of low temperature resistance and low humidity storage. However, after storage for a period of time, the dormancy period ended, physiological metabolism became vigorous, and fibrous roots grew on the epidermis of tuberous roots. In this case, improper storage can easily lead to root rot and deterioration. The yam to be stored should be thick and complete, with a head and a tail, and the epidermis should be free of mud, roots, wounds, scars, pests and frostbite. Before storage, it should be spread in a cool place to dry, so that the skin is slightly dry and aging. 1. Bury

Fine mud or river sand should be used for piling and burying on site. The method is as follows: on the ground of well-ventilated rooms, cellars and warehouses with low humidity, build a buried pit with a height of about 1 m with bricks, first spread a layer of dry fine soil or dry sand with a thickness of about 10 cm at the bottom of the pit, and then spread the selected and aired yam on the soil (sand) with a layer of yam and a layer of soil (sand). After burial, samples are usually taken once a month or so. Pay attention to handle with care when flipping, and don't scratch the root epidermis. If lesions are found, they should be picked out in time to prevent spread. If it is found that the water content of mud (sand) is too high, the pile can be turned over in advance.

You can also bury yam in containers such as baskets and crates. The method is as follows: firstly, put disinfection paper on the bottom of the box and around the box basket, then pile a layer of yam and a layer of soil (sand) to about 5 cm away from the mouth, and cover it with soil (sand). The time of checking can be determined according to the change of yam. It is easier to bury in a jar, as long as a layer of sediment is laid on the bottom of the jar first, and then a layer of yam and a layer of soil (sand) are piled 7 ~ 10 cm away from the jar mouth, and sealed with soil (sand).

Step 2: Basket storage

Spread dried and disinfected rice straw or wheat straw (preferably wheat straw) at the bottom and around the disinfected basket (box) without leaving any gaps. Then, stack the selected yam layer by layer until it is 80% full, cover it with straw to the mouth of the basket (box), and then pile it in a ventilated storage room by riding. Generally, the height is 3 wicker baskets or 4 crates. In order to prevent the influence of ground moisture on the root tuber, bricks or boards can be placed under the bottom basket (box) to keep a distance of about 10 cm from the ground. Keep the warehouse in a cool and dry environment.

3. Cold storage Put the selected yam in a crate, wrap it with four or five layers of paper around it, seal the mouth of the box with paper, and then pile it in the cold storage or put it on the shelf. The temperature of the storage room should be controlled at 0 ~ 2℃ and the relative humidity at 80% ~ 85%. Pay attention to ventilation. It can be preserved for more than half a year.
