The process of deep-frying can be divided into four stages: (1) Initial heating. The surface of the food reaches the boiling point of water. (2) Surface boiling. The hot oil surrounding the food causes water inside the food to evaporate. (3) Decreasing heat transfer rate. Crust continues to dehydrate, less heat conduction, rate of heat transfer through escaping steam decreases (reduced bubbling). The remaining moisture inside of the food is slowly heated to the boiling point of water, which cooks the food inside as if it were boiled, gelatinizing the starch and denaturing the proteins in the food. (4) Bubble end point. Water from inside the food is no longer evaporating. Remove the fried food before it begins to absorb oil. https://scienceandfooducla.wordpress.com/2015/08/25/fair-food-deep-frying / 2
