Tea oil is a unique traditional edible vegetable oil in China, and its production and development have a long history. According to the narrative book of Shan Hai Jing in the third century BC, "the staff is wood, and the south is oil and grain". The "official wood" mentioned here is Camellia oleifera, which means that people in China began to extract oil from Camellia oleifera fruit and eat it. Historically, tea oil used to be used for royal meals. According to historical records, using millet flour as raw material, together with almonds, peanuts, kelp, diced tofu, condiments and tea oil, is a recipe for imperial cuisine, which shows that enjoying tea oil is a status symbol. Camellia oleifera was planted as early as 100 BC, when Emperor Wu of the Han Dynasty. Except for sporadic distribution in Japan and a few countries in Southeast Asia, only China has large-scale cultivation. Wild camellia oil has been designated as a royal tribute because of its scarce resources and special effects on human health. Wild camellia oil is unique to China all over the world, and it is a treasure endowed by nature to China. Camellia oil in China has been eaten for more than 3,000 years. Li Shizhen, a medical scientist in Ming Dynasty, mentioned the dietotherapy function of camellia oil in Compendium of Materia Medica: "Tea seeds are bitter and cold, fragrant and toxic, and are mainly used to treat acute cough and expectorate." There are also many records in other ancient books. "Compendium of Catalogue" records that "tea oil can cure hemorrhoids and relieve damp heat", and "Dietary Spectrum of Rural Households" records that "tea oil can be used for cooking and daily use, and steamed food can make it shine, but the oil is the lightest and clearest, so all diseases are outspoken."
According to legend, at the end of the Yuan Dynasty, Zhu Yuanzhang was hunted by the Chen Youliang army to a camellia forest in Jianchang (now Yuanxi Village, Jiangxi Province). Seeing this situation, the old farmer who was picking camellia trees used his quick wits to dress up Zhu Yuanzhang as a farmer picking camellia fruits and survived. Zhu Yuanzhang affectionately called the old farmer the "old cousin" who saved his life.
My cousin saw Zhu Yuanzhang covered in injuries. Coat him with tea oil. A few days later, Zhu Yuanzhang felt that the wound on his body was healing and the redness gradually disappeared, so he was happy to call this camellia fruit "a miracle fruit given by God". Later, I rested at my cousin's house for a while, and my constipation got better again. He learned that it was because he ate tea oil every day. From then on. Zhu Yuanzhang had an indissoluble bond with tea oil.
After Zhu Yuanzhang unified the world, he named Jiangxi Tea Oil as "Imperial Edible Oil". Because of Ming Taizu's love and attention to tea oil. These great doctors made a thorough study of tea oil. Li Shizhen, an imperial doctor, recorded in Compendium of Materia Medica that "tea is cold in oil, cooling blood to stop bleeding, and clearing away heat and toxic materials. Indications: hepatic blood loss, deworming. "Heyun" tea seed for benefiting stomach and improving eyesight. Bitter and fragrant, it is mainly used to treat asthma and cough and scale. " Later, Jiangxi presented Yuanxi Village tea oil as a first-class tribute to the court, and the emperor was overjoyed and gave it the title of "Imperial Delicious Juice, Longevity Tea"! It is enough to show that enjoying tea oil is a status symbol.
Camellia oleifera is the main raw material, peanut, sesame and fried noodles are scientifically formulated and refined by traditional technology. Wuzhi County, Henan Province, is a traditional treasure trove of tributes. It tastes delicious, strong but not greasy, and rich in nutrition. It has a history of more than 2000 years. Qin dynasty called it Gan Lao Gao Tang, Han dynasty called it Gao Tang Ku Orange Tea, and Tang dynasty called it Camellia oleifera, which has been used ever since. According to historical records, during the Chu-Han dispute, Emperor Gaozu Liu Bang was injured and went to Wuzhi to recuperate and eat it, which was called Gongque Rice. Li Shangyin, a famous poet in the Tang Dynasty, once wrote a poem for Camellia oleifera, "The aroma is delicious, and An Ou rushes out of An Changchun". In Qing Dynasty, Yong Zhengdi went to Wuzhi to inspect dangerous workers in the Yellow River. Wu Shilu, a magistrate of a county, presented oil tea, and Yongzheng was overjoyed. He praised that "Huaiqing Camellia oleifera is as smooth as crisp, and no one can match the delicacies of mountains and seas", and spread the word that Camellia oleifera was widely opened, so Camellia oleifera became famous. Modern science has confirmed that the fatty acid composition of tea oil is very similar to olive oil, but its average composition is higher than olive oil. As a brand-new oil, tea seed oil is highly recognized by consumers in the main producing areas of tea seed oil, such as Fujian, the hinterland of Dabie Mountain in Anhui, Jiangxi, Henan, Zhejiang and Hunan, while consumers are not familiar with Shenzhen, Beijing and Guangzhou. These markets are not the main producing areas of tea seed oil, but they are potential consumption areas of tea seed oil. Tea oil is mainly concentrated in the mountainous and hilly areas of Dabie Mountain, Zhejiang, Jiangxi, Henan, Hunan and Guangxi in Anhui Province. It has always been regarded as a rare tribute, known as the king of clear oil, and even more nutritious than olive oil. Market prospect of tea oil. The main producing areas of Camellia oleifera in China are concentrated in Hunan, Henan, Jiangxi, Guangxi, Zhejiang, Fujian, Guangdong, Hubei, Guizhou, Anhui, Yunnan, Chongqing, Sichuan and Shaanxi provinces/0/4 counties (cities, districts). Among them, there are 142 counties (cities, districts) with planting area of over 654.38+10,000 mu, 97 counties (cities, districts) with planting area of 50,000-654.38+10,000 mu and 65438 counties (cities, districts) with planting area of 654.38+10,000-50,000 mu.
Camellia oleifera production integrates ecological benefits, economic benefits and social benefits, and plays a very important role in promoting comprehensive development in mountainous areas, protecting grain arable land, ensuring national grain and oil security, promoting farmers' employment and income increase, improving people's health level and accelerating the process of land greening. The State Council's 2009 National Camellia Oleifera Industry Development Plan shows that the output of Camellia Oleifera in 2009 was about 266,500 tons, with an output value of about 1 1 billion yuan. Judging from the tea oil system, it is mainly in Jiangxi, Guangxi, Hunan, Henan and Zhejiang. At the same time, it is proposed to cultivate Camellia oleifera industry into a pillar industry for prospering forests and enriching the people. During the "Twelfth Five-Year Plan" period, 32.5 million mu of oil-tea forest base will be built in 14 major oil-tea provinces. By 2020, China Camellia oleifera forest base is expected to reach 70 million mu, with an annual output of 2.5 million tons of camellia oil and a per capita consumption of 2 kilograms of camellia oil. Camellia oleifera is a unique oil-bearing tree species in China, and its fruit can extract an important natural green organic health-care edible oil-tea oil. According to Shan Hai Jing, Camellia oleifera has been cultivated in China for more than 2300 years. But unfortunately, for various reasons, tea oil has been "hidden in boudoir" for a long time, and people in China, especially in the northern region, generally lack sufficient understanding of tea oil. Due to the low yield per mu and long payback period, the industrialization of tea oil is slow or even retrogressive.
The comparative study of tea oil and olive oil by Institute of Nutrition and Food Safety of China Center for Disease Control and Prevention shows that although the components of tea oil and olive oil are similar, the dual function of tea oil in dietotherapy is actually better than olive oil and any other oil. Olive oil contains 75%-90% unsaturated fatty acids, and tea oil contains 85%-97% unsaturated fatty acids, which is the highest among all kinds of edible oils. Tea oil contains certain physiologically active substances, such as tea polyphenols and camellia glycosides, which are not found in olive oil. It can effectively improve cardiovascular and cerebrovascular diseases, reduce cholesterol and fasting blood sugar, inhibit the increase of triglyceride, and also has obvious effect on inhibiting cancer cells. At the same time, the molecular structure of tea oil is finer than olive oil, so you don't have to worry about side effects and greasy when eating.
The national grain and oil security situation is not optimistic. Foreign oil enterprises have basically monopolized China's edible oil market, and the equity and pricing power are controlled by foreign parties. However, the international market is unpredictable. Only by self-reliance and vigorous production of our own oil can we ensure the safety of grain and oil in China. Tea oil is the unique edible oil of China people!
