Cooking oil can also be adulterated? This is a problem many consumers encounter. How can we quickly identify it? What are the two magic weapons to see through the adulteration of cooking oil? Let's see how experts explain it.
There are two ways to detect adulterated oil at home: one is to smell the smell, use a chopstick or a small spoon, point to two drops of oil, place the palm, rub it to the palm of the hand, heat it up, and smell it before you smell it. The peanut oil mixed with flavor has a slight peanut flavor, but with the rubbing again, the smell of peanuts will become lighter.
Peanut oil mixed with soybean oil and palm oil can be identified by the second freezing method. Adjust the refrigerator to about 10 ℃, put the oil in for 10 minutes, half of the pure peanut oil will start to solidify, and the peanut oil mixed with a large amount of soybean oil will only slightly solidify at the bottom.
In addition, experts remind consumers that they should first check the commodity label when purchasing peanut oil, and only 'peanuts' should be included in the list of ingredients of real peanut oil, and attention should also be paid to the production process used. If peanut oil is kept for a long time, the fragrance will gradually fade until it disappears. Meanwhile, the acid value will also rise, the peroxide will increase, the taste will become poor, and the nutritional components will be destroyed.
