Heat transfer effect of oil
Make dishes fresh or crispy. In the cooking process, oil is widely used as a heat transfer medium. Due to the high ignition point of oil, it can speed up the cooking speed after heating, shorten the cooking time of food, and keep the raw materials fresh. Proper control of heating time and oil temperature can also make dishes crispy and fragrant, so it is often used in fried dishes.
Improve the color of dishes
Oil can make dishes present a variety of different colors. For example, when making battered dishes, due to different oil temperatures, fried or pan-fried dishes can present different colors such as white, golden, and dark red. Oil can be 1 times higher than the temperature of water or steam, quickly dissipating the moisture on the surface and inside of the raw materials, and the oil molecules penetrate into the inside of the raw materials, making the dishes emit an attractive aroma, thereby improving the flavor of the dishes. Sesame oil has a more special fragrance, which plays a great role in improving the flavor of dishes and improving the quality of dishes.
Increase nutritional value
During the cooking process, fat penetrates into the tissue of the raw materials, which not only improves the flavor of the dishes, but also supplements the nutritional value of some low-fat dishes, thereby increasing the calories of the dishes, that is, the nutritional value.
