Vacuum frying involves dehydrating and frying raw materials in a closed, vacuum environment. This type of frying makes it possible to preserve the original color of the raw materials and to produce a very pleasant sensation in the mouth. Traditional high temperature frying is between 160 and 185°C. If starchy foods are fried or cooked at high temperature (usually above 120°C), such as bread, sweet potato, taro, potato, etc., a large amount of "acrylamide" will be produced, which is a kind of chemical that has been shown to have adverse effects on humans in animal experiments. The frying carried out under vacuum allows a considerably reduced frying temperature of 90 to 110 ° C. In the vacuum state, the boiling point of water is lowered, and oil is used as a heat transfer fluid to allow the evaporation of the water content of the raw material in order to achieve the purpose of frying and dehydration, and to make the texture of food crispy.
