1. Grease

Although the air fryer consumes less oil than the wok and the cooking time is shorter than the oven, it does not mean it is completely healthy. In fact, there is less oil, but the heat is lower than ordinary frying, but it still requires a high temperature of about 180-200°C, and may take longer than direct frying in a pan.

2. Health risks

Starch in food ingredients may produce acrylamide at 120°C, which is harmful to health; proteins and oils produce heterocyclic amines and benzoyl amines at high temperatures respectively. Pyrene may cause cell genetic mutations or tumors. It can be seen that this new cooking method still has health risks, and it is not as good as steaming, boiling and other cooking methods in retaining the nutrients of food.
