How to distinguish sesame oil from sesame oil

Sesame oil is also known as sesame oil, which is mostly made from black sesame seeds. Because sesame has a very strong aroma after being fried, it is also called sesame oil in the north and sesame oil in the south. In fact, sesame oil and sesame oil are the same thing, both can be called sesame oil. Because the aroma of sesame oil can be divided into two types, fragrant oil and ordinary sesame oil. Sesame oil has a very strong sesame aroma and can be divided into small-milled sesame oil and machine-made sesame oil. The taste of ordinary sesame oil is lighter.

How to distinguish sesame oil from sesame oil :

1. Observation method : The pure sesame oil made by the water substitution method is transparent and bright in color, while ordinary sesame oil tends to have a small amount of turbidity.

2. Smell method : It is often said "identify the scent oil by smelling it". Because the production process of pure sesame oil retains the rich and pure sesame aroma, and the aroma lasts longer. The fragrance of pure sesame oil is its essential characteristic that distinguishes it from ordinary sesame oil. But so far, the identification method of this fragrance is still mainly based on sensory perception, and there is no quantitative standard.

3. Heating method : Pure sesame oil becomes slightly darker in color after heating, and no precipitate is produced, effectively retaining the original flavor and color of the dish; ordinary sesame oil is darker in color and has obvious precipitates after heating.

4. Freezing method : After being stored in the refrigerator at low temperature for 24 hours, ordinary sesame oil will show obvious crystallization or even complete crystallization, while pure sesame oil will still remain a crystal clear liquid state. It is precisely because of the quality of pure sesame oil that it does not crystallize when frozen that it is particularly suitable for use in cold dishes.

In addition, due to the rich nutritional value of pure sesame oil, its price is relatively high. Therefore, there are many unscrupulous vendors in the market who mix cottonseed oil, rapeseed oil, peanut oil, soybean oil and even lard into sesame oil. Therefore, consumers should choose regular manufacturers when purchasing. Choose oil from big brands to ensure that you are eating safe sesame oil.

The efficacy and function of sesame oil

1. Delaying aging : Sesame oil is rich in vitamin E, which has the function of promoting cell division and delaying aging. In addition, sesame oil is known as the scavenger of arteries and blood vessels. It is beneficial for moisturizing the skin, removing spots and improving vision. Therefore, it is most beneficial for middle-aged and elderly people to delay aging. The lecithin in sesame oil also has the effects of moisturizing the skin, removing spots (mainly age spots), preventing hair loss and premature graying of hair.

2. Protect blood vessels : Sesame oil contains about 40% unsaturated fatty acids such as linoleic acid and palmitic acid, which are easily decomposed, absorbed and utilized by the human body to promote the metabolism of cholesterol and help eliminate deposits on the walls of arterial blood vessels. Sesame oil can prevent the production of lipid peroxides in the body, thereby maintaining the integrity and normal function of cell membranes. It can also prevent other components in the body from being damaged by lipid peroxides. It can also reduce the accumulation of lipids in the body. It has a good effect on softening blood vessels and maintaining blood vessel elasticity.

3. Lubricate the intestines and promote bowel movements: For patients with habitual constipation, drinking a mouthful of sesame oil on an empty stomach in the morning and evening can lubricate the intestines and promote bowel movements.
