Sesame oil is a commonly used condiment and nutrient in life. When summer comes, many people use sesame oil because in the summer, many families will make some delicious cold dishes that everyone loves to eat. At this time, be sure to use sesame oil, because sesame oil is the soul of cold dishes, but when we choose sesame oil, we must pay attention!
A lot of people are eating these "fake sesame oils"! When buying sesame oil, you must know these truths!
First of all, when we buy it, we have to shake it like this
No matter what brand it is, shake it and observe the state of the sesame oil. If it produces transparent bubbles, it can disappear quickly. So this is usually pure sesame oil. If the bubbles disappear very slowly and the color is still yellow, it means it's mixed sesame oil.
The second is to observe the color of sesame oil
You can see that the color of pure sesame oil is light red. Or red with yellow. If you mix some cooked canola oil or something else in the incense burner, you will find that it is dark yellow or green. If it is mixed with cottonseed oil, it will be black and red.
The third is to take a look at the production process of sesame oil
Then the best production process to buy sesame oil is the hose method sesame oil, which is the familiar small grinding sesame oil, commonly known as "sesame oil". Generally speaking, this sesame oil is of better quality and has a mellow taste.
The fourth is to smell it
If the aroma is mellow and rich, then this is pure sesame oil. Its fragrance is strong and will not disappear for a long time. As soon as you open the lid, there is a very strong smell.
If the fragrance of your sesame oil is not strong, or the fragrance is too pungent, then the sesame oil you buy must be mixed. At this time, we try not to buy this, it may not be good for the body.
The above is the method of identifying sesame oil that we share in this issue. These methods are very practical, and you should know how to choose them the next time you buy them at the supermarket, right?
-
It should be distinguished from the taste, taste, texture, color, and smell of sesame oil, and the color of real sesame oil is relatively crystal clear, and it is also relatively good-smelling. In this way, you will be able to identify the real sesame oil.
-
It should be judged by the taste, smell, texture, color, manufacturer, and raw materials of sesame oil. The taste of real sesame oil is very good, and it will also have a relatively pure smell, the manufacturer is more formal, and the raw materials are also relatively good.
-
It is necessary to make a reasonable distinction according to the smell and taste, because there is still a big difference between real and fake sesame oil.
-
1. Look at the color. Pure sesame oil is slightly darker in color, light red or red with yellow, if mixed with cooked rapeseed oil, the color is dark yellow or blue, mixed with cottonseed oil will be black and red.
2. Smell. The fragrance of pure sesame oil is mellow and rich, such as adulteration, mixed with peanut oil or soybean oil, etc., the fragrance is pungent, with peanut or beany smell or burnt smell.
3. Shake. Shake the bottled sesame oil gently, if the bubbles produced are transparent and disappear quickly, it is generally pure sesame oil; If this oil bubble is opaque and yellow, and disappears slowly, it is inferior sesame oil.

1. In the first step, prepare a clean empty bowl and a chopstick, and then add cold water to the empty bowl.
2. In the second step, dip a drop of sesame oil into the calm cool water surface with chopsticks, and observe the condition of the oil droplets on the water surface at this time.
3. In the third step, pure sesame oil will show a thin and transparent oil flower on the water surface, while the oil flower of fake sesame oil on the water surface is small and thick, and it is not easy to diffuse. The left side of the picture below is the real sesame oil, and the right is the fake sesame oil.

l.Dip a drop of sesame oil with chopsticks and drop it on the surface of the water, and the pure sesame oil will show a thin and transparent large oil flower that is colorless and transparent, and then condensed into several small oil beads. The oil flowers of adulterated sesame oil are small, thick, and do not spread easily.
2.Use the refrigerator to freeze the sesame oil to minus 10, the pure sesame oil is liquid, and the fake sesame oil will condense.
3.Scoop up a spoonful of sesame oil and pour it into the oil from a high place. If the oil splash is pale yellow, it means that it is mixed with rapeseed oil; The oil splash is black, indicating that it is mixed with cottonseed oil; The oil splash is white, indicating that it is mixed with peanut oil.
Pure sesame oil flowers are golden yellow and disappear quickly (soybean oil flowers are also golden yellow, but disappear more slowly).
4.Take about 50 grams of sesame oil, put it in a clean fine glass bottle, and shake it vigorously, if there is no foam in the bottle, or although there is a small amount of foam but it disappears quickly, it is pure sesame oil; If white foam appears and disappears slowly, the sesame oil may be mixed with peanut oil or other vegetable oils.
5.Take a little oil and rub it with your hands, the pure fragrance is sesame oil; If there is beany smell, it may be mixed with soybean oil; If it has a spicy taste, it is mixed with rapeseed oil.

There are 4 main ways to identify bad or adulterated sesame oil:
1>. Smell: The fragrance of small grinding sesame oil is mellow, rich and unique. Mixed with peanut oil, soybean oil or rapeseed oil, etc., not only has a poor aroma, but also has other odors such as peanuts and beans.
2>. Look at the color: good sesame oil, light red or red with yellow in color; The color of machine-pressed sesame oil is lighter than that of small grinding sesame oil. Rapeseed oil is dark yellow in color, and cottonseed oil is black and red in color.
3> Observation method: Chopsticks dipped in a drop of oil, dropped on the cold water, the good sesame oil is a thin colorless and transparent large oil flower, about 1 cm in diameter. On the other hand, when cottonseed oil drops on the cold water, it shows a thicker and smaller yellow oil flower, and the difference is very obvious.
Other oil drops on the cold water and the shape is not the same as sesame oil.
4. > see the changes: sesame oil is clear and transparent in the sun, such as mixed cold water, opaque liquid under the light, if mixed with cold water, sesame oil will be stratified and easy to precipitate and deteriorate.

1. Pure sesame oil is light red or red with yellow, and small ground sesame oil is slightly darker in color, which is a brown-red transparent oily liquid. If sesame oil is mixed with other edible vegetable oils, the color changes: dark yellow when mixed with rapeseed oil, black and red when mixed with cottonseed oil, and yellow when mixed with refined cottonseed oil.
2. Look at pure sesame oil in the sun, clear and transparent. Mixed with cool water, which is an opaque liquid under light; Mixed with cold water, sesame oil will automatically stratify, precipitate and deteriorate; mixed with lard, it will turn white when heated; When mixed with rapeseed oil, the color will turn blue; Mix in cottonseed oil, heat will stick to the pan; Mixed with winter melon soup and rice soup, it will become turbid, and there will be precipitation after half an hour.
3. Place the sesame oil sample in the -10 refrigerator for frozen observation. Pure sesame oil remains liquid at this temperature, and adulterated sesame oil begins to solidify at this temperature.
4. Drop the oil sample into the palm of your hand and rub it vigorously with the palm of your other hand, due to the heat production of friction, the molecular movement of aromatic substances in the oil is accelerated, and the fragrance is easy to diffuse. If it is sesame oil, it will have a simple and strong sesame oil fragrance. If it is mixed with rapeseed oil, it will be mixed with the peculiar smell of rapeseed oil; If cottonseed oil is mixed with it, the aroma of the oil after rubbing is weak or not obvious.
5. The fragrance of small grinding sesame oil is mellow, rich and unique, such as mixed with peanut oil, soybean oil, refined oil, rapeseed oil, etc., not only the fragrance is poor, but also there will be peanuts, bean and other smells. Some sesame oils are blended with edible flavors, and the smell is relatively poor.

Taste identification. Taste a little sesame oil, pure sesame oil is slightly bitter, and feel strong fragrance sticky, adulterated sesame oil taste smooth, yuan astringent.
Taste identification. Rub a little sesame oil with the palm of your hand, the fragrance is pure sesame oil, and the spicy flavor is mixed with laissezel seed oil.
Clear water identification method. With chopsticks dipped in sesame oil and water, the pure sesame oil first shows colorless, transparent, thin large oil flowers, and then condenses into many small oil beads, adulterated sesame oil is not only thick and small, and the diffusion is slow.
-
Brand sesame oil should look for trademarks and anti-counterfeiting marks.
Secondly, look at the texture and color of the oil. When buying, turn the bottle back and forth to see the density, color and precipitation.
In addition, I am in favor of buying from the countryside, the quality is okay, but there is no guarantee of absolute quality.
When buying sesame oil in the bazaar, you can use the following 3 methods to identify its quality:
Look at the color: the sesame oil squeezed by the machine is lighter than the color of the small grinding sesame oil, the color of the small grinding sesame oil is red with yellow, and the color of cooked rapeseed oil is dark yellow.
Smell: After the sesame seeds are roasted by proper heat, the sesame ether becomes a sesame phenol with a certain fragrance, which is mellow and rich, and the adulterated sesame oil has a poor mellow taste, and has the smell of the adulterated mouth.
When the sesame oil is mixed with water, it will appear an opaque liquid.
Tips for buying sesame oil:
A look at the color: pure sesame oil is light red or red with yellow, if mixed with other oils, the color is different Rapeseed oil is dark yellow, cottonseed oil is black and red For products mixed with other vegetable oils, the water test method can be used: dip a drop of sesame oil with chopsticks and drop it on the calm water surface, pure sesame oil will show a thin and transparent large oil flower that is colorless and transparent, and a thicker and smaller oil flower will appear if it is adulterated
Second, look at the transparency: Generally, the sesame oil has good transparency and no turbidity
Third, look at whether there is sediment: the sesame oil has no precipitation and suspended solids, and the viscosity is small
Fourth, see whether there is stratification: if there is delamination, it is likely to be adulterated mixed oil
-
The positive sesame oil should have its unique strong fragrance, the color is yellow, slightly dark red, translucent, and there is no bubbles and delamination.
If the smell of sesame oil is mixed with other odors, such as musty smell and hala smell, it means that the oil has deteriorated and is not suitable for consumption; If the color is too dark and black-brown, it means that there are impurities; If there is delamination in the oil and a large number of bubbles in the oscillation, it means that the oil is mixed with water; If there is no strong smell of sesame oil, it means that it is fake sesame oil.
Identification of real and fake sesame oils.
1. Water identification. In a bowl of water, drop a drop of sesame oil, if it is pure sesame oil, it will form a thin oil flower in the water, and then it will quickly diffuse and condense into several oil beads; If the sesame oil is adulterated, the oil flowers formed are small and thick, and they are not easy to spread.
2. Color recognition. Fill the oil grapes with sesame oil, and then pour them into the oil cylinder from a high place, if the splash of oil is light yellow, it means that the sesame oil is mixed with rapeseed oil.
3. Identification by freezing method. The sesame oil is frozen in the refrigerator at -10 degrees Celsius for observation, the pure sesame oil is still liquid at this time, and the adulterated sesame oil begins to condense at this temperature.
4. Heating identification. Put the sesame oil into the pot and heat it, if it turns white after heating, it means that it is mixed with lard; If it becomes clear after heating, it means that rapeseed oil has been added; If it becomes muddy after heating, it means that it has been mixed with rice soup, and sediment will appear soon after.

Sesame oil identification method: generally high-grade oil color is light, low-grade color is dark (except sesame oil); Good transparency, no turbidity; No precipitation and suspended solids, low viscosity; There is no delamination phenomenon (if there is delamination, it is likely to be adulterated mixed oil, and sesame oil is more adulterated); It has its normal unique smell without a sour odor.
Storage method: choose a reasonable storage container. When there is more oil, you can choose a ceramic cylinder, and when there is less oil, you can choose a dark glass bottle that is opaque, and try to reduce the diameter of the container.
After the oil is filled, the bottle mouth is sealed to isolate the oil from the air and prevent the oxidation of the edible oil. The storage container is placed in a cool, dark place, dry place with a low temperature.
