How to tell if peanut oil is fake

1. Look**.

2. Look at the quality standards of peanut oil.

3. Look at the senses.

4. Smell its smell.

5. Look at its solidification temperature.

6. Practical inspection.

A "look": look at the color of the oil. High-quality peanut oil is light yellow and transparent, clear in color and no precipitated substance, while dark and turbid in color is inferior peanut oil.

2. "Smell": smell the smell of oil. High-quality peanut oil has a fragrant smell and pure taste; The aroma is strong and the peanut flavor is insufficient.

Three "frozen": refrigerated peanut oil. This is the easiest and most obvious way to identify peanut oil, especially in winter.

Turn the refrigerator to 10 degrees Celsius and put the oil in for about 10 minutes, and half of the pure peanut oil will begin to solidify. 4. "Stir-frying": Try it yourself when stir-frying.

Pure peanut oil, no overflow, no foam, no oil smoke, fragrant and pleasant for high-quality peanut oil.

First, first of all, we must look at the bottle label and product introduction materials. The pressed oil does not go through high-temperature refining, and does not go through the "six deodorizations" such as deodorization, decolorization, degreasing, degumming, dewaxing, and deacidification, and there is no chemical solvent residue problem.

Let's look at the oil concentration. Good pressed oil has a high concentration, the oil is hung on the wall for a long time, and the amount used is only 1 2 of ordinary oil, which fundamentally achieves the health purpose of "eating less oil and eating better oil".

Second, smell the aroma of the oil. Open the bottle (pressed oil is a natural raw material fragrance), drop a little peanut oil into the palm of the hand and rub until the palm is hot. Pure peanut oil has a strong peanut fragrance, and the fragrance is long-lasting after repeated rubbing; The "peanut oil" mixed with peanut flavor gradually fades after repeated rubbing.

Third, it is better than oil products. The pressing process has high requirements for raw materials, low oil yield, high nutritional value and high cost of peanuts, so it is relatively high.

Fourth, refrigerate to distinguish the real from the fake. After storing the oil in the freezer for 10 minutes and then taking it out, the pure peanut oil is semi-solidified, the soybean oil mixed with it is almost non-solidified, and the palm oil mixed with it is completely solidified.

The purity of peanut oil in a 5-liter package, less than 80 yuan, is very questionable.

1. Look. Look at the color of the oil. High-quality peanut oil is light yellow and transparent, clear in color and no precipitated substance, while dark and turbid in color is inferior peanut oil.

2. Smell. Smell the oil. High-quality peanut oil has a fragrant smell and pure taste; The fragrance is strong and the peanut flavor is insufficient, and the peculiar smell is inferior oil.

You can also drop one or two drops of peanut oil into the palm of your hand, rub it until the palm is hot, smell it before you get it to your nose, and the pure peanut oil can smell the rich fragrance of peanut oil, and the peanut oil mixed with flavor begins to have a slight peanut oil fragrance.

Rubbing again, the pure peanut oil still maintains a strong peanut oil fragrance, while the adulterated peanut oil fragrance is getting weaker and weaker, and the odor may be produced in the process.

3. Freezing. Refrigerate peanut oil. Turn the refrigerator to 10, put the oil in for about 10 minutes, half of the pure peanut oil has begun to solidify, the peanut oil mixed with a large amount of soybean oil only slightly solidifies at the bottom, and most or all of the peanut oil mixed with palm oil coagulates.

And the crystals are white crystals. If it's cold, you don't even need to put it in the refrigerator, just put it on the balcony in the open air for a while, and you can see the difference.

Fourth, fry. Pure peanut oil, no overflow, no foam, no oil smoke, fragrant and pleasant for high-quality peanut oil. Heating is easy to overflow, foaming, large oil smoke, and even darker and blacker peanut oil is inferior peanut oil.

Cooking oil is a must for our daily cooking and stir-frying, which can make the dishes taste better. Edible oil includes animal oil and vegetable oil, and vegetable oil is generally pressed from grain crops, such as peanut oil, sesame oil, rapeseed oil and so on. When we buy edible oil, we should pay attention not to try to be cheap, otherwise it is likely to be mixed with other oils.

So how do you see the authenticity of peanut oil?

The first one is to smell. Using chopsticks or a small spoon, put a drop or two of oil on the palm of your hand, rub it until your palm is hot, and then smell it in front of your nose. If it is good peanut oil, you can smell the strong fragrance of peanut oil, and the peanut oil mixed with flavor will have a stronger fragrance. It's getting lighter and lighter.

In addition, put the peanut oil in the pot and heat it, and the quality of the smoke must be the worst. As the temperature rises, the color of high-quality peanut oil remains basically unchanged, and the taste is still smooth and mellow. If the peanut oil is left for too long, the aroma will gradually fade until it disappears, and at the same time, the taste will deteriorate, and the nutrients will be destroyed.

Peanut oil adulteration is generally mixed with soybean oil and palm oil, and some will also be mixed with cheaper cottonseed oil, or even unrefined cottonseed oil, the situation is even worse. If peanut oil is mixed with cottonseed oil, the smell will be unpleasant. The cottonseed oil is red, and as soon as the pot is heated, the smell of the cottonseed oil comes out.

The price of peanut oil is too cheap is likely to be blended with other oils, calculated by 5 liters of oil, the normal cost of peanut oil should be about 60 yuan, and the sales volume of more than 70 yuan is considered normal**.

1.Smell the oil. Open the bottle (pressed oil is a natural raw material), drop a little peanut oil in the palm of your hand and rub it until the palm is warm.

Pure peanut oil has a strong peanut fragrance, and the fragrance lasts for a long time after repeated rubbing; The peanut oil, which is mixed with peanut flavor, gradually fades away after repeated rubbing.

2.More expensive than oil. The crushing process has high requirements for raw materials, low oil yield, high nutritional value and high cost of peanuts, so it is relatively high.

3.Refrigerate to distinguish between the real and the fake. Store the oil in the refrigerator at 10°C for 10 minutes before removing. Pure peanut oil is semi-solidified, the soybean oil mixed with it has almost no solidification, and the palm oil mixed with palm oil is completely solidified.

1. Observe the color of peanut oil. Light yellow and transparent, the color is very bright, and there is no precipitation material for high-quality peanuts, and the oil color is dark and turbid, and it is inferior peanut oil.

2. Smell the smell of peanut oil with your nose. If the smell is fragrant and the peanut flavor is strong, it is high-quality peanut oil, if the fragrance is strong and the peanut flavor is not enough liquid index, or if it has a peculiar smell, it is inferior oil.

3. Use the method of frying for identification. If there is no overflow and foam and oil smoke, the fragrance is very fragrant, it is pure peanut oil, if it is easy to overflow the pot when heated, foam, large oil smoke, and even darker color, it is inferior peanut oil.

1. The smell and taste are different.

The first-level pressed peanut oil is odorless and tastes good; Aromatic peanut oil is smelly and tastes good.

2. The acid value is different mgkoh g.

The first pressed peanut oil is 0 20;Peanut oil peanut oil is 0 30.

3. The smoke point is different.

The first pressed peanut oil is 215; Peanut oil is 205.
