Corn oil is golden, transparent and fragrant, which is especially suitable for fast cooking and fried food. When fried at high temperature, it has considerable stability.

Selection skills of edible oil
1, look at the color
The color of the oil of the same brand is similar, but if the color difference between two barrels of different brands of edible oil is obvious, it means that there is something wrong with the quality of the oil. Different brands and different raw materials have different colors, so pay attention to observation when buying. Good quality soybean oil is dark yellow, generally light yellow; Rapeseed oil is yellow, with some green or golden yellow; Peanut oil is light yellow or orange, and cottonseed oil is light yellow.
Step 2 smell it
When the lid of the oil drum is opened, the unique smell of oil will come to the nose. Pure fragrance means better quality of oil. If there are other odors, there is something wrong with the oil. You can also touch a little cooking oil with your fingers, rub it on your palm, rub it back and forth, and smell it after rubbing, so you can judge further.
