How to distinguish real peanut oil from fake.

1. "Smell": smell the smell of 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.

2 "Frozen": refrigerate 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, 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 the "peanut oil" mixed with palm oil is mostly or completely coagulated, and the crystalline is 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.

3 "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.

However, now the counterfeiting technology of peanut oil is getting higher and higher, and some unscrupulous traders will not only replace peanut oil with other **low** edible oil, but some even add some chemicals to the edible oil, so that the inferior oil looks like the "beautiful appearance" of high-quality peanut oil, but does not have the "delicious taste" of pure peanut oil.

4 "Stir-fry": Try it yourself when stir-frying. 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.

4) Moisture: Refined peanut oil has less moisture, clarity and transparency, and no turbidity; Crude oil or cold-pressed oil has a lot of moisture and a lot of sediment on the oil bottom. When the oil in the barrel is pulled out of the skewer tube and observed, the sediment is white milky.

5) Taste: The freshly squeezed oil tastes delicious, the old oil tastes light, and the oil processed from moldy peanut kernels with bad raw materials has a bitter and sour taste.
