Development history
Sesame oil has a very long history in China. As early as the Three Kingdoms period, there have been written records, "The History of the Three Kingdoms? Wei Zhi: "Sun Quan went to Hefei New Town, and the cage was full of relaxation ... It was smashed into a torch and filled with sesame oil ..." As a lighting fuel, sesame oil at that time was made by pressing sesame seeds with stone mortar method or wood pressing method. Zhang Hua, a native of A Jin, recorded in the Natural History that "frying sesame oil makes water smokeless, but when it no longer boils, it is still cold". And the method of making douchi with sesame oil ... Steaming with sesame oil and stopping the violence in three episodes "is the earliest record of sesame oil culture. It has been 1600 years. During the Southern and Northern Dynasties, sesame oil was widely used in catering. During the Tang and Song Dynasties, sesame oil was considered as the best edible vegetable oil and was widely used.
Xiao Mo sesame oil is now mainly in Zhumadian, Henan.
The production of small mill oil in Zhumadian area was recorded as early as the Ming Dynasty. By the early Qing Dynasty, the sesame oil in Zhumadian had become a palace offering, and the production of sesame oil in Zhumadian had also become a scale. Nine times out of ten, farmers know how to squeeze oil. With the oil mill in Tanaka village, every family is an "oiler", the streets are jingling and there are "oil sellers" everywhere, gradually forming a sesame oil diet culture.
Zhang Dawei, the inheritor of ancient sesame oil, was born in Shangcai Oil-pressing Family. There is also a Pangu stone mill handed down from generation to generation, with a diameter of 1.65 meters and a weight of more than 900 kilograms. Small ground sesame oil also has its unique health care function. In Compendium of Materia Medica, sesame is introduced as "benefiting qi, promoting granulation, filling brain marrow, strengthening physique for a long time, clearing eyes and ears, resisting thirst and prolonging life". Make "white hair turn black" and "get rid of all chronic diseases ..."
According to the scientific analysis of nutritionists, sesame is rich in nutrients needed by human body, which can really delay people's aging and beauty. Eating sesame oil has obvious effects on protecting blood vessels, relaxing bowels, relieving cough and alcohol and tobacco poisoning, protecting voice and treating rhinitis.
According to historical records, in the spring of the tenth year of Yongzheng (1732), Tao, governor of Caodao, and his accompanying officials came to Runan House (known as Tianzhong in ancient times) to inspect the people's feelings. When they came to Zhumadian, a group of people were walking in the street when they suddenly smelled a strong fragrance. They asked the accompanying officials and replied: There is a small sesame oil mill here, and this fragrance comes from this mill. Master Tao is very happy to go. After about a hundred steps, he saw a rainbow flying not far away, which read "Dou Da": the oil mill in the sky. When I came to the oil mill, I saw the smoke curling up, the sesame seeds in the cauldron were steaming, and the sesame oil in the other cauldron was bright and fragrant. I said to the officials with great joy and excitement: this is an excellent sacrifice. Immediately seal the ten altars and deliver them to Beijing in person. Yongzheng tasted the dishes he cooked, and immediately ordered Runan officials to expand sesame planting and vigorously promote the processing of sesame oil. All the oil produced by the oil mill is graded by Lao Zhangman, first-class tribute, second-class delivery to the government, and the rest are sold freely. At this point, Xiao Mo sesame oil in Zhumadian, which has been circulating for hundreds of years, is known to outsiders.
Some nutritionists believe that ground sesame oil should be one of the best table flavors for middle-aged and elderly people.
First of all, the rich aroma of sesame oil can not only stimulate the appetite of middle-aged and elderly people whose digestive function has been weakened, but also facilitate the absorption of nutrients. The digestion and absorption rate of sesame oil itself is also very high, reaching 98%. Sesame oil contains a lot of oil, which has a good laxative effect and a certain preventive effect and curative effect on constipation.
Secondly, sesame oil has a good effect of softening blood vessels and maintaining blood vessel elasticity. Its rich vitamin E is beneficial to maintain the integrity and normal function of cell membrane and reduce the accumulation of lipids in the body.
Thirdly, lecithin in sesame oil can not only moisturize the skin, but also remove spots, especially senile spots.
Finally, the long-term use of sesame oil by middle-aged and elderly people can also prevent hair loss and premature gray hair; Especially black sesame oil. For middle-aged people with atrophied gums, especially those who have the habit of smoking and drinking, long-term use of sesame oil can protect gums and mouth.

Now, Mr. Zhang Dawei, a descendant of Lao Zhangman, has been adhering to the ancestral motto of "Honest management and people-oriented". A small oil mill has gradually developed into a production base that covers an area of more than 30 mu and meets the requirements of international standards-Zhumadian Gu Wei Xiaomao Sesame Oil Development Co., Ltd., and has attracted an American investment company to invest 5 million yuan. At present, the company's products are indirectly exported to Russia, South Korea, Japan, Lithuania and other countries.
Walking into the office hall of the company, I saw an ancient stone mill handed down from the late Qing Dynasty. This stone mill has a diameter of1.66m and a weight of1800kg. It can be said that the ancient stone grinds the sky for a thousand years, and the century-old ancient square conveys the ancient taste.

According to the grinding process of a well-known brand of sesame oil in China, it is summarized as follows:
Small ground sesame oil is produced by "water substitution method"
Classic process 1: sesame embryo culture
Sesame oil for kittens is rich in nutrition. The key is to cultivate sesame seeds into sesame embryos before feeding raw materials to promote the production of sesamol, sesamin, sesamin and other nutrients beneficial to human body. Through scientific research, this technology is highly consistent with modern life science. This is not available in other processes.
Classic process 2: stone grinding
The grinding process of stone mill is low temperature and low pressure, and the process temperature is only 60-65℃, which will not destroy the aromatic substances and functional nutrients in sesame oil.
Classic Process 3: Replacing Oil Recovery with Water
Using high-quality drinking water, the oil embryo can be easily separated, and no chemical solvent is needed in the process of oil extraction, and there is no chemical solvent residue. At the same time, due to the high specific gravity of sesame oil, heavy metals harmful to human body are also precipitated from sesame oil, so the sesame oil prepared by this method is completely healthy.
Classic process 4: patented physical purification technology
Cat sesame oil adopts patented physical filtration technology, using natural plant fiber as medium, through two-stage electronic constant temperature natural precipitation and 36-layer physical filtration, impurities and foreign bodies in sesame oil are filtered out. After purification, the appearance of kitten sesame oil is crystal clear, and its color, fragrance and taste are timeless.

Recently, some citizens have reported that sesame oil is not fragrant, and they will feel dizzy after smelling it for a long time. They suspect that sesame oil is fake. After the interview, the reporter found that the price of sesame seeds in the wholesale market is 4.4 yuan per catty, 2.5 to 3 kilograms of sesame seeds are needed to make 1 kg sesame oil, and the raw material cost of 1 kg sesame oil is more than 10 yuan. In the market, the lowest price sesame oil only sells 6 yuan money. The reporter's in-depth interview revealed the true face of 6 yuan sesame oil.
Low-priced sesame oil flooded the market.
65438+1On October 28th, the reporter came to the Antarctic condiment wholesale market in Daowai District. In the first store, the reporter asked about the price of sesame oil, and the store told the reporter "10 yuan 1 kg." When the second company was established, the reporter said that he was a purchasing staff of the hotel and wanted to buy sesame oil in bulk. Tell the reporter directly, "7 yuan 1 kg". When the reporter wanted to leave, the organization stopped the reporter and said that he would go to 6 yuan if he wanted more. When the reporter asked about the quality, she told the reporter that it was for the hotel, not for you.
In many markets such as Jingyang Farmers' Market outside Daowai, the reporter found that the market of sesame oil is mostly like this: asking price 10 yuan, bargaining 7 yuan. If it is a big customer, the lowest price is in 6 yuan.
Small and medium-sized restaurants do not use pure sesame oil.
The reporter came to Wang Gang comprehensive farmers' market. In this market, the reporter found an operator selling sesame oil, and the price offered by the operator to the reporter was 10 yuan 1 kg. When the reporter asked for a cheaper price, the boss of the company said that this price is already the wholesale price. The reporter said that the market price in the urban area is cheaper than this wholesale market, and the business owner revealed the secret to the reporter, and the cheap sesame oil was made. According to the business owner, the price per catty is less than 10 yuan, and it is made of salad oil, sesame oil essence and black oil. According to business owners, pure sesame oil used to be only about 7 yuan. Because sesame is not expensive and does not make money, there are not many fakes. Now that the price of sesame has gone up, so has the price of oil, and some small oil mills have begun to make fakes. He said that there are still some big hotels that continue to use his pure sesame oil, and small and medium-sized hotels use blended sesame oil to reduce costs. So where can I buy sesame oil essence? A person familiar with the matter revealed: "Chengde Street and Caoshi Street in Daowai District sell sesame oil essence, and chemical stores can also buy it."
Sesame essence is easy to buy.
The reporter found traces of sesame oil essence in several additive shops in Chengde Street, Daowai District. In an additive shop in Chengde Street, the reporter asked if there was any essence specially made for sesame oil. The boss gave the reporter a glass bottle marked "small ground sesame oil flavor". The boss told reporters that this essence is better, a bottle of 58 yuan. When the reporter asked what proportion of sesame oil to use, he said, "1000: 1, and a little colored' black oil' will do." The reporter asked what oil was used for modulation. The boss said impatiently, "You can use whatever oil you want. Anyway, it is all ground sesame oil. "
In another store, the salesgirl told the reporter that the sesame oil essence there is out of stock now, but it can be bought immediately, and the price ranges from 20 yuan to 68 yuan. When the reporter asked if the seasoning effect of cheap sesame oil essence was good, he said, "The cheap flavor is not good." When the reporter asked if there would be any problems, the salesgirl said that sesame oil essence was edible, and it would be fine if a whole bottle was poured into her mouth. It depends on what oil you use to make it. If you want to use inferior oil cheaply.
Blending sesame oil is profitable
According to the operators of small ground sesame oil in the grain and oil market, the small ground sesame oil bought by 7 Qian Yuan 1 kg does not contain sesame at all. Generally, salad oil is about 4 yuan per catty, sesame oil is about 40 yuan per bottle, and black oil is about 4 yuan per catty. The cost of blending sesame oil is more than 4 yuan per catty. If it is sold in 5 yuan per catty, the profit per catty will reach 1 yuan. If you use inferior salad oil, the cost will be lower. The production of fake sesame oil is profiteering, which is also the root cause of the proliferation of fake sesame oil. According to insiders, it is very easy to blend fake sesame oil. Most manufacturers of fake sesame oil even make it directly in their own homes and then sell it in the market. Driven by huge profits, there are also many fake sesame oil workshops.
Grinding sesame seeds in the workshop as a cover
65438+1At 2 o'clock in the afternoon on October 29th, the reporter went to a small sesame oil processing workshop named "Sesame Oil Workshop" in Yixing Comprehensive Market, nangang district. There are many bottles of sesame oil without any trademark on the ground in front of the workshop. The reporter found a stone mill in the shop. The raw material for grinding the top is really sesame, but this machine is not pressing oil, but grinding sesame paste. The oil press next to it seems that it has not been started for a long time, and it is full of dust.
I heard that the reporter is the owner of a hot pot restaurant. After the female shopkeeper pulled the reporter to the pavement, the reporter saw some black iron barrels and plastic barrels piled up everywhere. She conveniently opened an iron drum, saying that these are all for hot pot restaurants, and the minimum 8 yuan money per catty. If you pay in cash, it will be cheaper. The reporter asked her, this oil will not eat bad people, right? She hesitated and said, don't worry, although the taste is not pure and delicious, it will never eat bad people. The machine for grinding sesame paste is just a gesture.
The blended sesame oil is sold at the price of pure sesame oil, and the quality can not be guaranteed, which not only makes huge profits, but also may cause quality problems. The relevant departments should control these counterfeiters.
