(1) Wash all kinds of vegetables, cut into pieces and put them away compactly. It is said that the principle of cutting root vegetables is to expose a large cross section as much as possible, and when placed on a baking tray, let the cross section face up.
(2) You can cut the oven in half and preheat it, about 190 degrees.
(3) Sprinkle a layer of oil, twist each vegetable by hand, let them get more oil, sprinkle some salt and grind some black pepper.
(4) Leave the middle layer of the oven for 40 minutes and the other cooked ones for 20 minutes. The key is to look at the size of your own cut. If not, adjust more. After cooking, put it on a plate and sprinkle some coriander.
2. Disadvantages of eating food in the oven for a long time:
(1) reduces the utilization rate of protein: "Maillard reaction" will occur during barbecue. With the fragrance, vitamins are destroyed, protein degeneration and amino acids are also destroyed, which seriously affects the intake of the three. Therefore, eating barbecue will affect the utilization of the above substances.
(2) Carcinogenesis: In Maillard reaction, nucleic acids and most amino acids in meat are decomposed by heat, resulting in gene mutation, which may lead to cancer. In addition, in the barbecue environment, some carcinogens will enter the human body through the skin, respiratory tract, digestive tract and other ways to induce cancer.
