How to choose edible oil group purchase? Let's talk about it

There are three points in choosing edible oil:

Look at the color first. Generally speaking, the higher the degree of refining, the lighter the color of oil. Of course, all kinds of vegetable oils will have a unique color, and it is impossible and unnecessary to refine them to no color.

Second, look at transparency. Choose clear and transparent oil. The higher the transparency, the better.

Third, it smells tasteless. Take a drop or two of oil on your palm. No smell (spicy or irritating) can be smelled after hand friction heating. Don't buy it if it smells bad.

The functions of edible oil are:

1, heat transfer of oil

Make dishes look fresh or crisp. In the cooking process, grease is widely used as a heat transfer medium. Because of the high ignition point of oil, heating can speed up cooking and shorten the cooking time of food, thus keeping the raw materials fresh and tender. Proper control of heating time and oil temperature can also make dishes crisp and crisp, so it is often used for cooking.

2. Improve the color of dishes

Oil can make dishes appear different colors. For example, when making hanging dishes and fixing dishes, fried or fried dishes can show different colors such as white, golden yellow and deep red due to different oil temperatures. The temperature of edible oil can be 1 times higher than that of water or steam, which can quickly disperse the water on the surface and inside of raw materials.

Step 3 increase nutrition

In the cooking process, fat permeates into the tissue of raw materials, which not only improves the flavor of dishes, but also supplements the nutritional components of some low-fat dishes, thus improving the calorie of dishes, that is, nutritional value.
