The choice of wok material is a topic that many people care about. Here I want to remind everyone not to just blindly pursue high-priced products. A good price does not mean good quality, advertising costs must be charged back from the price, just choose the one with high cost performance. What kind of material is good for the frying pan? A study shows that cooking vegetables in an iron pan can reduce the loss of vitamin C in vegetables. The researchers experimented with 7 kinds of fresh vegetables including cucumber, tomato, green vegetables and cabbage. It was found that the preserved vitamin C content of dishes cooked in iron pans was significantly higher than that in stainless steel pans and non-stick pans. The researchers believe that from the perspective of increasing vitamin C intake and health, cooking vegetables in iron pots should be the first choice. Although cooking in an aluminum pan can retain more vitamin C, the easily leached aluminum element is not good for health. In addition, adding salt when the vegetables are cooked can preserve more vitamin C than when they are not cooked, and it can also reduce the exudation of water in the vegetables and ensure their fresh taste.
Frequent cooking in an iron pan is good for preventing iron deficiency anemia.
First, the thickness of the pot 5 is required to be above 3 mm, preferably 4 mm. This is because the temperature of the smokeless pot requires a stable medium conduction, and this thickness is conducive to the heat storage of the pot on the one hand, and it is not easy to cool quickly. On the one hand, heat is also conducive to maintaining the stability of the overall temperature.
Second, it is required that the heat conductivity of the frying pan should be strong and fast. Among the metals, the ranking is silver>copper>aluminum>iron>stainless steel. Silver is too expensive, and copper is also expensive. It is a bit wasteful to make a pot. Toxic patina, aluminum has just the right heat conduction speed and the price is right, iron will rust and the heat conduction is not very ideal Stainless steel is not strong in heat conduction although it is very bright In terms of neutrality, aluminum is the most suitable heat conduction medium, so the current smokeless pans are basically Aluminum is used as the basic material, but to prevent aluminum from harming the human body, it is required to wrap and isolate the aluminum well, so hard oxidation is a process that seals the aluminum and strengthens the hardness and surface of the surface at the same time. Strength, after this treatment, the original white aluminum becomes black, so the smokeless pots you see are basically black, and there is this kind of three-layer steel pot (also called composite diamond, remember This does not refer to stainless steel pots with multiple bottoms, and it is only used in Chinese cooking) to combine aluminum with hard stainless steel at the top and bottom! As I just said, the first thing is to require the heat conduction capacity of the pot to be stronger and faster.
Three, it is a reasonable and appropriate temperature operation, that is, your fire source is under control The higher the volatilization point, vegetable oil, soybean oil, it is basically not recommended to use better blended oil, peanut oil, sunflower oil, etc.) If you burn it on a high fire, you will burn any wok with smoke. You must master the method, so generally as long as If you meet the above two points and add your own reasonable control to the third point, you can achieve a smoke-free effect. The usual operation is to preheat the whole pot with high heat for 2 to 3 minutes, and then switch to medium-fire three-layer steel. The fire has to be properly adjusted to a low level before pouring oil. In short, it is right to use a high fire first and then a medium and small fire!
In addition, everyone must remember not to buy products coated with Teflon (so-called non-stick pans), and try not to use wrought iron products. Generally, wrought iron woks are only suitable for use in large restaurants, because thin heat transfer is very difficult. Not suitable for fast home use.
