3. Corn oil
Corn oil is golden and transparent in color and fragrant, which is especially suitable for fast cooking and frying food. When frying at high temperature, it has considerable stability. The fried food is crispy and delicious, and the cooked dishes can not only keep the original color and flavor of the dishes, but also lose the nutritional value. Cold dishes mixed with corn oil have a pleasant smell.

In many people's minds, lard is considered as an unhealthy oil because it contains saturated fatty acids. However, lard has good heat resistance and less oxidative polymerization after being heated for a long time, so it is suitable for processing pastry and frying food to create a crisp taste.
Selection skills of edible oil
1, look at the color
The color of the same brand of oil is almost the same, 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 oil. Different brands and raw materials have different colors of oil, so pay attention to observation when buying. Soybean oil with good quality is dark yellow, and generally it is light yellow; Rapeseed oil is yellow with some green or golden yellow; Peanut oil is light yellow or light orange, and cottonseed oil is light yellow.
2. smell the smell
After the oil drum cover is opened, the unique fragrance of oil will come to the nose. The pure fragrance means that the quality of oil is better. If there are other peculiar smells, it means that there is something wrong with the oil. You can also touch a little cooking oil with your fingers, smear it on the palm of your hand, rub it back and forth, and smell it after rubbing, which can further judge.
