After using animal oil for quite a long time, because of the birth of the technology of extracting oil, there is the beginning of vegetarian oil. The refining of vegetarian oil started around Han. Liu Xi "interpretation of the name" has "crabapple oil, pounded and coated with silk, dry and hair shape like oil. Apricot oil is also like this." Crabapple is a fruit tree, is a kind of Ringo, also known as "flower red" and "sand fruit". Zeng is the general name of the silk fabric, ancient called "silk", Han called "Zeng". The fruit and apricot will be mashed and stirred and then coated on the silk fabric, after drying as if it were oil, in fact, it is not the real oil. According to the "days in the record" in the statement, the early vegetarian oil from the "Ushu" in the extraction: "Jingzhou has a tree, the name of the Ushu, in fact, such as hu Ma Zi, [left hand right a word of life] its juice, can be fat, its flavor is also like pig fat." "Wusu", actually "Sapium sebiferum", deciduous tree, with seeds, white wax on the outside. Seed shells and kernels can indeed be extracted oil, but the extracted oil can only be used as an industrial raw material.

Three Kingdoms - Wei Zhi: "Sun Quan to the new city of Hefei, full of pampered galloped to go to the collection of dozens of strong men, folding pine for the torch, filled with sesame oil, from the upper winds to set fire to the thieves attack equipment." Here to sesame oil as lighting fuel. Jin Zhang Hua "Museum - Volume IV - Physics", has been recorded: "frying sesame oil. Water gas exhaust smoke-free, do not reboil is still cold. Can be stirred in the hand. Getting water is the flame up, scattered pawns do not go out." Visible, sesame oil is the earliest vegetarian cooking oil. Zhang Hua's "Museum" has been recorded on the use of sesame oil to make soybean drum method: "foreign countries have edamame method: to bitter wine soaked beans, storming the very dry, steamed in sesame oil, and then storm three times is stopped."

According to the "Book of Han", sesame is Zhang Sai brought back from the western region of the seeds, so sesame was first named "hu ma".

According to the "Book of Han", sesame seeds were brought back by Zhang Sai from the western region, so sesame seeds were first named "hu ma". Dawan is the name of the ancient western country, now CIS Central Asia Fergana Basin. Han, sesame has been produced in large quantities, how the invention of oil extraction technology, how to operate in the early days, but there is no written record. "Qimin Yaojutsu" recorded "white hu ma", "eight-pronged hu ma" two varieties, stating that "the white oil". Tao Hongjing "Materia Medica": "good raw squeeze, if steamed and fried, only available for food and light ear." But no specific instructions, sesame oil in the Tang and Song Dynasty became very common cooking with vegetarian oil. Tang Meng [words first] sheng "food therapy herb": "white sesame oil, often used for food." Dream Stream Brush Tales: "Now the northern people like to use hemp oil to fry things, do not ask what things, all fried in oil. Qingli in the group of bachelors will be in the Yutang, so that people set up a basket of raw clams, so that the breakfast

people cooking, long and do not come. Guests were surprised, make people check. The guests were surprised to see a person to check. They said that the frying has been scorched black, but not yet rotten. The guests did not laugh."

Song Zhuang Jiyu "Chicken Ribs" in a section devoted to oil, detailing the extraction of various plant oils in the Song Dynasty, that the oil, "hemp for the upper. Zhuang Jiyu records, when the Hedong food hemp oil, Shaanxi food almonds, red and blue flower seeds, cranberry oil, Shandong food Cangdongzi oil. In addition, there are Pun Kunzi oil (suspected to be castor oil), Sapium sebiferum seed oil. Wuzhou, frequency state coastal food fish oil. "xuanhe in, jingxi big apologize for people eat each other", and "refining brain for oil, to food peddling in the four directions can not be identified."

To the Ming Dynasty, the plant extracted oil varieties are increasing. Tiangongkaiwu" records: "Where the oil for food, caraway, vegetable clothing (Lai clothing that is radish), soybean, woad for the top; Su Ma, rue Taiwan son of the next; tea son of the next, amaranth seed of the next; hemp seed for the next." The Tiangongkaiwu recorded that at the time of oil extraction, "Beijing has a grinding method, North Korea has a pounding method to treat hemp, and the rest of them are from the press also." The method of extracting various rapeseed oil is recorded: "Take all the hemp seeds into the kettle, stir-fry slowly over a gentle fire, through the aroma, and then crushed by the steam. Where the fried hemp vegetable seeds should be cast in a pan, the depth of six inches, cast the seed in the, tossing the most diligent. If the bottom of the kettle is too deep, mixing slowly, then the fire is injured, the loss of oil quality. Frying pan also slant on the stove, and the steamer is very different. Where the mill buried in the groove of the soil, on which a wooden pole with an iron dao, two people on the lift and push it. Capital wide, the stone for the cattle mill, a cow's strength can rival ten people. There are also not subject to grinding and grinding, the cotton and so on is also. Both grind and sieve, choose the coarse and then grind, fine into the kettle before being steamed. Steam to take out enough to rice straw and wheat straw wrapped in cake shape, the cake outside the hoop or iron beaten into or broken contemptuous twisted and pricked, and squeezed in the inch is a stable fit. Where oil causes gas to take, there are born in the time of no retort, parcel slack is water and fire Yu steam gas wandering, this loss of oil. Those who can pour and wrap quickly and quickly hoop, get more oil." "The package of oil out of the dregs of the storage name is 'withered cake', where houma, lai tai, rue Taiwan all cakes are re-crushed, sieve away the straw man, and then steam and then wrapped and then squeezed, the first time to get two points of oil the second time to get one point of oil. If Sapium sebiferum is a squeeze has been exhausted out, do not have to be again. If the boiling method, and with two kettles, will be crushed into a kettle of castor, sesame seeds, injection of water boiling frying, on the floating foam that is the oil, with a spoon swept away dumped in a dry kettle, the slow fire under the boiling dry water, oil that is into it. However, the number of oil is reduced after all kill. North grinding hemp oil method, to coarse linen bag jie stranded." "Tiangong Kaiwu" said, with the oil method, houma per stone to get forty pounds of oil, Laptop per stone to get twenty-seven pounds of oil, brassica tablets per stone to get thirty pounds, woad, amaranth per stone to get thirty pounds of tea to get fifteen pounds of soybeans to get nine pounds. However, "Tian Gong Kai Wu" did not mention peanut oil. Peanut oil is the latest vegetable oil to be born.

Qing Tang Zui "Dian Hai Yu Heng Zhi" only began to remember peanut oil: "peanut for the first in the South fruit, in order to fund the most extensive civilian. Between the Song and Yuan, and cotton, melon, sweet potatoes and so on, Guangdong estimate from the sea countries to get their seeds back to plant. Called cotton said 'jibe', called sweet potato day 'groundnut'. Peanut day 'groundnut' ...... peanut to oil for the top. Therefore, from Fujian and Guangdong, no not eat peanut oil." The time recorded by Tanzui was during the Qianlong period of the Qing Dynasty. But made in the Qing Dynasty - Jiaqing eighteen years of "adjusting the disease diet discernment" "oil" chapter, but only remember the four kinds of vegetable oils: fat hemp oil (sesame oil), soybean oil, rue oil (rapeseed oil), jibai oil (cotton seed oil), and no peanut oil. Li Tiuyuan's Notes on the East of Guangdong, "Oil," states that "olive oil, vegetable oil, kibai oil, and flaxseed oil are all edible. However, the rate of tea seed oil white for the beauty, said 'white tea oil'. Black fried caramelized as a small milled sesame oil called 'Yang oil'." And no mention of peanut oil.

"Tune Ding set" also has "oil theory": "vegetable oil to take its thick, sesame oil to take its fragrance, cooking must be used both. Hemp oil altar buried cellar for a few days, pulling the oil gas is available. And, hemp oil boil all the water, that is, no smoke, but also cold can be used. Also, a small mill will be sesame frying charcoal grinding, the oil is fragrant, big car sesame oil is not as good as also. Soybean oil, vegetable oil into the water boiled, called 'cooked oil', to do the dishes, does not damage the spleen and stomach, can be buried in the cellar over the better."
