How to distinguish whether peanut oil is true or false

【Material Observation】

Generally speaking, peanut oil is divided into raw and cooked squeezed. The color of raw squeezed peanut oil is generally light orange-yellow; the color of ripe squeezed peanut oil is deep orange-yellow. Both types are relatively fresh and transparent. Pure peanut oil generally condenses and does not flow when the temperature is below 3℃. If it is mixed with lard or palm tung oil, it starts to condense and does not flow when the temperature is 10℃.

[Smell method]

Put a few oils on the palm of your hand, rub it with your fingers and feel slightly hot, then blow a burst of heat with your mouth. If the peanut oil is pure, it will have a strong peanut-specific fragrance without peculiar smell.

[Refrigeration method]

Refrigerate peanut oil. This is the easiest and most obvious way to identify peanut oil, especially in winter. Adjust the refrigerator freezer 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 solidifies slightly at the bottom, and most or all of the peanut oil mixed with palm oil is condensed, 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 open-air balcony for a while, you can see the difference

【Heating Method】

Just put a small amount of peanut oil in the palm of your hand and combine your hands for a few vigorous grindings. The real peanut oil has a fragrant taste, while the adulterated peanut oil has no obvious taste.

【Combustion method】

Roll a piece of paper into a paper tube and immerse it in peanut oil, take it out and ignite it with fire. After the peanut oil is really burned, the flame on the paper tube does not emit much smoke, and there are no small water droplets falling on the ground.
