Sesame oil has a very long history in China. As early as the Three Kingdoms, there was a written record that "Sun Quan went to Hefei New Town, the cage was full of relaxation ... and he broke pine branches into torches and poured sesame oil ..." At that time, sesame oil was used as lighting fuel, which 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 distributed in Henan and Hebei provinces of China.

Small ground sesame oil also has its unique health care function. The introduction of sesame in Compendium of Materia Medica is "benefiting qi and promoting granulation, filling brain marrow, keeping fit for a long time, strengthening bones and muscles, clearing eyes and ears, resisting hunger and 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.

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.
