When I was a child, any baby's bottom was red. You can try it with tea oil, just overnight. It created a miracle! Secondly, in our country, women eat tea oil in confinement, which is good for the recovery of their bodies.
Tea oil is extremely valuable in my hometown. Camellia oleifera grows slowly and generally takes more than 6 years to blossom and bear fruit. The fruiting period is extremely long. From flowering to fruiting, they go through five seasons "autumn, winter, spring, summer and autumn" in two years. Camellia oleifera is a tree species that blooms and bears fruit at the same time, with flowers and fruits coexisting, and there is an inherent saying of "having children".
When I was a child, I often went to the mountains with my grandmother to pick camellia oleifera. Mature Camellia oleifera is bright in color and slightly green. Every time I go up the mountain, grandma knocks down the camellia oleifera tree by tree with a bamboo pole. I use a basket to pick under the tree. I can pick a basket of camellia oleifera when it gets dark.
Newly picked Camellia oleifera fruits are stored indoors for one week (for post-ripening), and then dried for 3 or 4 days, allowing them to crack naturally. Most fruits of Camellia oleifera can be separated naturally, and those without separation need to be peeled by hand. Shelled seeds are the main raw materials for baking in winter. After the shelled seeds are crushed by a crusher, they can be steamed and fried to extract oil. The oil yield of Camellia oleifera seeds is generally 25% ~ 35%, and the residue after oil pressing can be used to feed fish after fermentation.
Note: 1000 kg of tea fruit can sun about 240 kg of tea seeds and extract 50 kg of oil.
Our tea oil can be sold to 1 kg in 80 yuan, but most farmers are reluctant to eat it, so they go to the streets to sell it to subsidize their families. When I was a child, I earned all my books by selling tea oil. You can earn thousands of dollars in an autumn, far faster than selling vegetables.
How high is the value of tea oil? Tea oil is a pure natural high-grade edible vegetable oil. During the period of Zhu Yuanzhang in the Ming Dynasty, tea oil was named "oil for the palace".
Tea oil mainly contains no substances harmful to human body such as erucic acid and cholesterol. The content of unsaturated fatty acids is as high as 90%, which is the highest in edible oil. It can prevent human arteriosclerosis, and is internationally called "longevity oil".
Ordinary edible oil will produce peroxide at high temperature, which is very harmful to human body. When frying with tea oil, it can be fried continuously at 220℃ for 20 hours without deterioration. Ordinary edible oil must be heated until it is cooked before it can be used in cold salad, and tea oil can be used in cold salad without heating. Tea oil is "the top grade in edible oil".
Tea oil is fragrant and easily absorbed by human body, especially suitable for baby's delicate stomach.
Why do you feel that few people eat tea oil? Tea oil has high nutritional value and medicinal value, not because people are unwilling to eat it, but because it is too expensive. The price of the same amount of tea oil is 10 times that of rapeseed oil, which is simply beyond the consumption capacity of ordinary people. Therefore, as ordinary people, people will think that few people eat tea oil. In fact, the authentic tea oil has been preserved just after processing. Most of the tea oil sold in the market is impure, even so, the price is still very high.
Camellia oleifera was planted in China as early as 2000 years ago in the Western Han Dynasty. At present, the planting area of Camellia oleifera in China exceeds 45 million mu, with an annual output of 270,000 tons of Camellia oleifera, while the market demand exceeds 500,000 tons, which is a big gap. However, due to the high investment in the early stage of planting Camellia oleifera, it failed to bear fruit in the first six years, and the difficulty of picking and processing led to the small planting area of Camellia oleifera in China.
An acre of land can also squeeze out 50 kilograms of oil, and tea trees are also divided into years. If the output is small, the annual output will be directly halved. Picking requires a lot of manpower, picking and drying, then selecting shells and drying. These steps must be completed by manpower. It is natural that tea oil is expensive.
To sum up, tea oil is a high-grade vegetable oil. Many people want to eat tea oil, but it is too expensive, so not many people eat tea oil.
Tea oil is the most attractive taste in my hometown. Have you ever eaten tea oil?
Tea seed oil is the main product here. It's been there as long as I can remember. Eat tea seed oil! In recent years, with people's concern for health, the price of this oil is getting higher every year!
Take my home as an example. In 2000, tea seed oil was only sold for ten yuan a catty, and my family fried 100 kilograms of oil. My family just ate and didn't sell it! 10 year is 3 1 kg. At that time, you could fry about 200 Jin, sell it for a hundred years in A Jin, and then plant some rape. Your home is enough! After 15, the price went up all the way, forty, fifty, sixty, and sold more than seventy at the highest time!
In recent years, my family has only one 30-40 kg left, and all the others have been sold. I will take money to eat rapeseed oil (my family has no rapeseed), and selling tea seed oil has tens of thousands of dollars a year! The price is too expensive, I can't bear to stay too long. One catty of tea oil can be exchanged for five or six catties of rapeseed oil!
My family's books are reserved by friends every year. I will inform them when I squeeze oil and go directly to the oil mill to pick them up! Because they are old customers, I want to make sure that what I give them is 100% true, so that they can rest assured!
In recent years, my family has eaten less tea seed oil, and there is not much left. When you are ready to eat on holidays, you will cook with tea seed oil! Usually used rapeseed oil is also ok! (The picture has been used, please forgive me! )
Tea tree oil, commonly known as tea oil, is planted in hilly and mountainous areas in the south. It bloomed in the forest from the end of1October to1month of the previous year. White flowers have honey juice, attracting bees, bearing fruit next spring, sprouting new leaves, making Camellia Abel. Edible, and the tree is full of tea bubbles. After peeling, you can pick it and eat it until it is ripe.
However, the current camellia oleifera is an improved variety. I don't know if it's camellia Abel. And tea bubbles. When I was a child, I saw it in Changning, my hometown in Hengyang. Grandpa's generation was planted all over the mountain in the early 1950s. In the 1960s, 1970s and early 1980s, the tall Camellia oleifera was still bearing fruit and playing its economic value. I joined the collective production team from the age of 12 to the age of 16, and picked camellia oleifera fruit every year. Camellia oleifera is as tall as a tree. Those who can't pick them are hooked down with hooks, or climbed to branches to pick fruits.
The fruit ripening speed of Camellia oleifera is regular, and you can only go into the mountains to pick tea fruits after the cold dew. It is also said that the oil yield of fruits picked after tyrants is higher.
Picking tea fruits, there are people all over the mountain, and the scene is really lively. There are singers and jokes. Pay attention to your discretion and don't talk nonsense, or you will be at your own risk. Maybe we will hold a mass meeting to criticize and have a fight.
Among my peers in the village, I am the most active, energetic and organized. At this time, the team leader and the village instructor will come to me, assign me tasks, organize people to guard the mountain and prevent people from stealing tea fruits.
After receiving the task, we have been drying tea fruits, sorting out tea shells, putting them in storage and squeezing oil. I choose people for it, and the production team makes up the work points.
In other words, the tea oil pressing process: first, break the dried fruit, then peel off the seeds and dry the black seeds; Secondly, the seeds are dried and baked with charcoal fire to evaporate the water vapor of the seeds; Third, it is best to grind them into powder and agglomerate; Fourthly, put the powder blocks into wooden barrels, steam them in a sealed cauldron, pick hay on the mat, pick cakes, pack them, squeeze them and get oil.
It used to be a primitive wooden pressing tool with sharp points, sharp points and auxiliary points. It has to be operated by a strong man, and only a large person can eat this bowl of rice.
Oil, squeezed out, smells fragrant and fragrant, turns golden yellow, and thieves shine. Tea oil is boiled fish, fried beef and dog meat, and mutton and chicken with fishy smell are the best edible oils.
These wonderful moments are still just aftertaste!
When it comes to camellia oleifera, I have the most say.
The second house in my family is a brick-and-wood courtyard house bought in 1996, which was built in the 1970s. The reservoir is in front, followed by tea trees and fir trees. There are more than ten acres.
In the past, I had to help my mother pick tea seeds in autumn, and I could pick a few hundred kilograms of dried seeds (in the past, I only bought a house without contracting the back hill, and everyone else in the village would pick it). These camellia trees are about 40 cm in diameter and three stories high. One tree can pick one or two hundred catties of wet tea seeds. But it takes a lot of time, and the top of the tree depends on me and my brother. Pick one week in a row. After picking it, it will dry, and it will take four or five days to get the oil dry. After drying, you should choose tea seeds and separate the shells to extract oil. The key is to finally transport it to an oil mill more than ten kilometers away to extract oil. This process is very difficult.
These tea trees (planted in villages and hills near the reservoir) were introduced by the government at the beginning, with strong disease resistance and high oil yield. About 30%. The quality of oil is very good. My mother not only keeps the squeezed oil at home, but also sells it to acquaintances.
After 2005, because of road construction and pond digging, we should also prepare the decoration of the house behind. My father cut down many tea trees that used to be near the mountain. Others that were too close to the house were also cut down. In addition, there was no firewood cutting in the empty mountain before, and all kinds of wild trees and shrubs grew wildly, and the shorter tea trees were covered by the sun and could not bear fruit and wither. The taller ones seem to have a sense of crisis. They have grown taller and all the seeds are at the top of the tree. My parents are old, and we are all in other provinces (my brother is a professional soldier), so we pick fewer tea seeds every year. Although my father cleared the miscellaneous trees and shrubs on the mountain in two years after 20 10, he also eliminated the old tea trees and kept the new trees from seed dropping to seed setting. In recent years, the main reason is that new trees have borne seeds, and they can squeeze hundreds of kilograms every year, but most of the oil has been sold. 50/ kg sold to a fixed person. Only a few kilograms were left for squeezing dried tofu during the Chinese New Year.
In recent two years, due to the national poverty alleviation, camellia oleifera has also been distributed in the village, although its varieties are excellent. But it will take several years to bear seeds. Although the conditions are not enough, our family also asked the village cadres to plant some in their own responsible soil.
Living in the countryside, these can only be regarded as additional agricultural products, but they are definitely better than nothing. Parents are also used to picking tea seeds and squeezing tea oil.
The price of Camellia oleifera is getting higher every year, and Camellia oleifera will never wither.
Tea oil is a pure natural woody edible vegetable oil advocated and popularized in China at present. It is also the first health plant edible oil promoted by FAO, and it is also the only oil that doctors call curable! More than 90% of the global camellia seed oil production comes from China, which is extracted from camellia seeds and is the highest edible vegetable oil at present. Moreover, China has a history of planting Camellia oleifera for 2,000 years and is a veritable Camellia oleifera country.
As a northeast person, the oil we eat is mainly soybean oil, because our side is the main soybean producing area. Many rural areas also have their own oil mills, and farmers can pull beans to extract oil. One side of the soil and water support one side, the northeast people like to eat soybean oil, the southerners like to eat peanut oil and rapeseed oil, and the rich and people with children at home like to eat olive oil. However, tea oil is the best in terms of pure nature and nutrients.
People who produce tea oil may think that tea oil is not so mysterious and usually eat it. Only after two years of commercialization, the price became more expensive, so they ate less. Are ordinary people alive? Not so much attention, but peanut oil and soybean oil have become more common.
In some areas, people seldom eat tea oil, because many people are no longer in the countryside, and most of them are working in other places, so they have no time to collect seeds and extract oil. Because the market is expensive, they simply seldom eat. Camellia oleifera seed is very common if it is not used for oil extraction, and it is useless to fall on the ground, so its value will not be reflected.
Camellia oleifera is a tree with low productivity. Although China has more than 2000 years of planting experience, it can't make up for its own shortcomings. It takes about 6 years for us to plant a camellia oil tree to blossom and bear fruit, and camellia oil likes warm environment and is very afraid of cold, which may be the reason why it can't be planted in a large area. The optimum growth temperature of Camellia oleifera is 16 18, and the optimum average temperature at flowering stage is 12 13. In addition, the fruiting period of Camellia oleifera is particularly long, and it takes about 12 months from flowering and pollination to fruit ripening. If you go to the producing area, you will find strange phenomena. Some tea seeds are fully mature, and some camellias are still in full bloom. This is what folks call "pregnant with a child in her arms"!
Because the growth period of Camellia oleifera is extremely long, if we are growers, we must carry out reasonable topdressing to increase the yield. Usually in the first five years of tea oil trees, it is best to apply nitrogen fertilizer several times. We can choose ordinary urea as nitrogen fertilizer, and we don't need to pay special attention to the biuret content, as long as we can buy genuine urea in agricultural stores. Each Camellia oleifera should be topdressing with urea about 2 liang, divided into 4-5 times. But it should be noted that when topdressing and digging ditches, don't be too close to the plants. It is best to leave about 10CM and apply holes from four directions of seedlings.
When Camellia oleifera grows to 6 years, it reaches the high-yield period of Camellia oleifera. At this time, it is necessary to supplement not only a large amount of nitrogen fertilizer, but also phosphorus and potassium fertilizer. The best ratio of nitrogen, phosphorus and potassium in our fertilizer is 3: 2: 1, or high nitrogen is the main factor. Topdressing 2-3 times a year, and topdressing 2 taels per tea tree is enough.
When the camellia oleifera is over 10 years old, it produces the most seeds and needs nutrition most. At this time, both roots and plants grow strong and tall, and more and more fertilizers are needed. It is suggested that chemical fertilizer 1 kg should be applied to each old tree every year. The ratio of nitrogen, phosphorus and potassium is 5: 3: 2. In addition, the time for topdressing should be well grasped. Farmers who have been planting for a long time usually do this. They don't mix according to the above ratio, but topdressing urea 4 Liang every February, and potash fertilizer is the main fertilizer in May, with 2 Liang per plant. The last topdressing is in July every year, which is beneficial to inflorescence elongation.
Of course, during the whole growing period, we still need to prevent insects and diseases. The main diseases of Camellia oleifera include bituminous coal disease, anthracnose, soft rot and so on. The main pests are scale insects, so it is necessary to prevent early root carving, because a thick waxy layer will form in the later stage, which is difficult to control with general chemicals.
Spraying with sulfur mixture can prevent diseases such as bituminous coal disease. As for the specific dosage of Xia Dong in two seasons, we can refer to the products we bought to illustrate scientific and rational drug use. For example, anthrax, we can start spraying once every half month and three times in a row after the camellia oil tree blooms 10 day. This kind of anthrax is the most harmful. Not only crops will get this disease, but also people and livestock will get it. When farmers saw the disease, they had a headache. It is suggested that farmers spray 80% Sheng Da M-45 wettable powder +25% benomyl EC 1000~ 1500 times solution after rain to control the spread and reduce the harm. For soft rot, it is suggested to spray 50% WP 1000~ 1500 times solution +75% thiophanate-methyl 500 times solution+1% Bordeaux solution every half month in summer for prevention and control. The cost is relatively high. If it is not serious, there can only be one solution.
First of all, pure natural tea oil is a very high-grade edible vegetable oil, which was named "Palace Oil" more than 2,000 years ago. Small partners in the northeast can bypass it. In Northeast China, we eat the most oils, such as soybean oil and lard, but we don't know much about tea oil.
It is said that tea oil has high nutritional value because it does not contain some harmful substances such as erucic acid and cholesterol. In addition, the content of unsaturated fatty acids in tea oil is as high as 90%, which is called "longevity oil" internationally.
Moreover, the melting point of tea oil is very high, and peroxide harmful to human body will not be produced at high temperature. Although the price of olive oil is much more expensive than that of tea oil, the melting point of olive oil is low, that is to say, when the temperature of olive oil reaches 60, it will start to smoke and a lot of nutrients will be lost. So it's best to cool all the olive oil. Ercha oil can be fried continuously at 220℃ for 20 hours without deterioration, which is incomparable to other edible oils.
Tea oil has high nutritional value and uneven quality after commercialization. Moreover, the output of tea oil is very low, not only the young tree period is long, but also it takes a long time to blossom and bear fruit. Generally, it takes about 7 years from planting to harvesting. Moreover, one acre of land can only produce 100 kilograms of tea seeds and 50 kilograms of oil a year. Although the price is ok, the enthusiasm of farmers for planting and picking is not high.
Although the price of olive oil is much more expensive than that of tea oil, in terms of sales volume, olive oil has higher sales volume and higher acceptance. But tea oil is much more expensive than rapeseed oil and peanut oil, not to mention soybean oil. Therefore, from the perspective of people's daily consumption willingness, tea oil is not dominant. Moreover, the truly pure natural tea oil, like most of the tea oil sold in the market, is impure and has been preserved just after processing.
Camellia oleifera cannot be planted in a large area in the future because of its own limitations, and the output has not been able to come up. At present, China is the main planting area of tea oil trees, with an annual planting area of about 45 million mu and an annual output of only about 270,000 tons of tea oil. At present, the annual market demand exceeds 500,000 tons, and the gap is still very large.
In a word, although the nutritional value of tea oil is comprehensive, there are not many farmers planting it because of its low yield and low input-output ratio. In addition, the price is more than 10 times higher than that of ordinary edible oil. We are all ordinary people, and our children have to pay the mortgage when they go to school. This kind of high-end oil can't be eaten every day!
I am engaged in agriculture, and your question is not very accurate! Tea oil is a unique variety in southern China, which is rich in nutrition and widely used. Known as the king of oil! Its nutritional value is much higher than that of olive oil, the first edible oil admired in the west at present, and it is also the first edible oil recommended by the United Nations Grain and Oil Organization. At present, Camellia oleifera is mainly produced in Hunan, Jiangxi and Zhejiang, and a small amount is also planted in Guizhou, Guangxi and Sichuan. It can only grow in hilly and mountainous areas with 25 to 30 degrees north latitude and 800 meters above sea level, and the price is very expensive. Because the planting period is too long (generally, it takes nearly 10 year from emergence to maturity) and the yield is too small (the yield of old camellia oleifera is only a dozen kilograms per mu, compared with 400,000 tons in Hunan Province last year), ordinary people grow it for their own consumption, and some of them sell it very expensive (the local camellia oil has been sold to 60 yuan for a catty, and the refined camellia oil ranges from 100 to more than 300 kilograms). But there are many supermarkets in the south, but the so-called camellia oil below 100 yuan a catty is fake! After 20 10, Chinese agricultural scientists have cultivated high-yield and high-quality Camellia oleifera seedlings after many years of experiments, and the yield per mu of Camellia oleifera can reach more than 80 kg in the fruiting period. In addition, Hunan Province has developed Camellia oleifera industry into a key advantage industry in agriculture. I believe that high-quality camellia oil will enter the homes of ordinary people in ten or five years at most!
It is unknown whether tea seed oil is as good as it is said, but it is also true that tea seed oil is more expensive than olive oil. This kind of oil costs several hundred yuan for 2L, which is not the object of mass consumption ... Some people think that people will keep in good health now, and if the value of keeping in good health is emphasized, some people will be willing to consume it. This idea is just like what Eight-Nation Alliance calculated when it invaded China: If we sell fur coats to China, a populous country, we will get rich by buying one. Only in China do we know that most people only wear clothes. Can't afford such expensive tea oil, which is a national condition. ...
More than a decade ago, tea seed oil was still common in southern China. Every mature season, tea farmers and children go to the mountains to beat tea fruits. The process from picking to finally squeezing oil by traditional pressing method is more complicated and time-consuming than expected.
But hard work is worth it. Tea seed oil is more special than most plants, and it is very mellow! Local people think that tea oil is a good product, and in many cases they are unwilling to sell it. They keep some for their own use and give some gifts to others. However, more than ten years later, tea oil has declined, and fewer people really eat it. I think it is influenced by three aspects.
1, the popularity of tea oil is low.
Theoretically, the quality of tea oil is better than that of olive oil. According to experts, it is "better than oil" and is the best edible oil in the world! But many people in the north don't know about tea oil, let alone eat it.
The reason is that the growth environment of tea fruit trees requires high requirements, coupled with low yield and long payback period, and so on. Therefore, it is rare in the market and its influence is not deep. People naturally lack enough knowledge of tea oil, and of course few people eat it.
1, the price of tea oil is developing rapidly.
In rural areas, the price of tea oil is more affordable than peanut oil. But if you look at today's price, the seed oil of improved varieties is not less than a catty of 80 yuan, and even the local tea oil is sold at 100 to 200, which is simply a luxury and exclusive to the rich.
Imagine that the working class is willing to buy? You can buy a barrel of soybean oil at the price of one catty. I want to compare it with the next one.
The price of tea oil is singing all the way! Nothing more than its nutritional value has been excavated, saying that it can beautify the skin and blacken the hair, saying that it can enhance immunity, supplement various nutrients and prevent various diseases ... As a result, it has grasped the concept that all people pay attention to health care today.
2. It's hard to tell whether the tea oil on the market is true or false.
The prices of different varieties of tea oil vary greatly, ranging from tens of yuan to hundreds of yuan. Which is really good tea oil? Although there are strict enforcement standards for tea oil, what is the real situation? Fakes are repeatedly banned, how can people buy with confidence? If you don't pay attention, you will buy inferior tea oil at a high price. Isn't that right? Perhaps the real high-quality tea oil is in the folk oil mill, and it may no longer be hyped, so that more people can eat it. This is to push tea oil to the international market.
Tea oil, which used to be common in the south, is rarely eaten now. Hehe, now every meal can be cooked with tea oil, which basically belongs to local tyrants. Ordinary people, few people can cook with tea oil every day, and occasionally it is possible. Let me analyze the main reasons.
First, the price is expensive, which is the main reason. The price of tea oil is 70~80 yuan/kg, which is really unaffordable for the general public. Although I have planted dozens of acres of tea trees at home, I seldom use tea oil to stir-fry dishes. In the past, when frying chicken or dog meat or frying sugar and oil on holidays, my father would only give us a little tea oil to taste. Because rural income is limited, this kind of tea oil is more valuable at home. Some of them are for sale, and some are for gifts, so they can only be tasted at home.
Second, it is difficult to grow. The planting cycle of tea seed trees is still quite long. It takes 7-8 years from planting to picking (seedlings), and only those who have planted it know how much effort. Even if there is a bumper harvest, it takes a lot of manpower and energy to pick tea seeds up the mountain, down the mountain, dry tea seeds and pick up tea seed shells, which is difficult for ordinary people to eat.
Third, the output is low, which is another factor that leads to the high price of tea seed oil. The oil yield of the best tea seeds is only 30%, which means that only three or two oils can be extracted from a catty of tea seeds. At present, the yield of most tea seed mountains will not exceed 50 kg/mu, and the tea seed trees are divided into years, so this yield is actually pitifully low.
In a word, I think it's not that people don't like tea oil, but that tea oil is too expensive for most people to eat, which is the main reason why people eat less. In fact, tea seed oil is a very green and high-quality oil, which is better than other edible oils in China. It has many medicinal and health functions and is called "Oriental Olive Oil".
