There is an identification method that does not require the help of any equipment, which is very convenient to use and very effective.This method is called the friction method. We find two kinds of sesame oil, dip a drop of sesame oil with the index fingers of the left and right hands, and then rub it with the thumbs of the left and right hands respectively. Due to friction, heat production, the movement of aromatic molecules in the oil intensifies, and the fragrance will spread.After rubbing for a minute, let's smell the sesame oil on our fingertips. If the sesame oil is not adulterated, there will only be a strong fragrance of sesame oil; if it is mixed with other vegetable oils, in addition to the aroma of sesame oil, it will also be mixed with the odor of adulterated oils; if it is blended with flavors and pigments, because the flavors are volatile, the smell will be more nasal at first, and then there will be basically no smell of sesame oil, and the taste of real sesame oil will be more lasting. After rubbing for half an hour, you can still get the smell of sesame oil from your fingertips.This method is simple and easy, has strong reliability, and is most suitable for on-site identification.
