Reader Guo is very curious, kitchen utensils improper selection, improper use, a great impact on health? Has many years of sales of a brand of kitchen utensils, some small details will harm the health of the family. For example, cheap aluminum. Aluminum cookware are relatively light, the price is cheap, quick heating, so it is widely favored by the owners, however, as long as the aluminum cookware put salt or food containing acidic substances, will produce a chemical reaction with aluminum, lead to contamination of food, because aluminum is a very active metal element. The best alternative is stainless steel, ceramics, glass, iron, etc., in particular, pig iron, it will give us the necessary trace elements of the human body. Secondly, the plastic spatula and other plastic products. When cooking or soup with a plastic spatula, stir the number of food would have melted, and the plastic is chemical products, should try to choose bamboo, wood or glass, stainless steel spatula.
In addition, metal containers. Like acidic foods such as tomatoes, pickles, fruit, lemons, and even tea and wine, and metal containers will produce a chemical reaction, resulting in the pollution of food, or even toxic. The best choice for these things is glass. (zinc: zinc can lead to some toxic zinc into food; bronze or brass: wine, tea, and coffee together will produce toxic substances; lead: tin is very beautiful, but inside it except the metal lead, tin tin is beyond the traditional lead and tin containing 25% of the 75%. So try not to be used for holding food tins. )

Wok occupied in the kitchen appliances in the position is very important. In the face of the market many pan products, we should be how to choose a wok? Today let home Master teach you how to choose wok.

Tips to buy wok

A "look", the pot surface is smooth, but not smooth as a mirror, because the casting process caused by Pan have irregular shallow wrinkles. In general, wok are some rough, this is inevitable, with a long time will become smooth. A small bulge is generally iron, has little effect on the quality of the pot, but the harm of small pits on the quality of the pot is larger, the need for the purchase of note.

Two "listen", the uneven thickness of the pot is not good, the purchase can be overturned bottom of the pot, the pot center concave counter with a finger tapping with a hard object. The sound of the pot, the larger the feeling of vibration, the better. In addition, there is a cat on the rust is not necessarily the quality is not good, there is rust pot that stored for a long time, and the storage time of the pot as long as possible, so that the internal organization of pot can be more stable, beginning with a crack. It is worth mentioning that the iron pan ear is best to use wood or other insulating material package, if it is easy to hot wok ear.

What material is good with the wok

A study shows that with the wok cooking vegetables can reduce the loss of vitamin C in vegetables. The researchers made experiments on 7 kinds of fresh vegetables, such as cucumber, tomato, green vegetables, cabbage and so on. Results: the use of the wok cooked dishes, preservation of vitamin C was significantly higher than that of the use of stainless steel pot and pan. Researchers believe that the human body from increased vitamin C intake and health considerations, should be the first choice of wok cooking vegetables. Aluminum cooking although it can retain more vitamin C, but Al dissolution of health.

In addition, dish fry put can save more vitamin C than immature salt when the salt, vegetables can reduce water leakage, ensure its taste fresh. Often with wok cooking, for the prevention of iron deficiency anemia is good.

A pot of 5, is the thickness of 3 mm or more, preferably 4 mm which is best because smokeless temperature requires a stable transmission media and this one in favor of the thickness of heat storage pot is not easy to cold and hot hand is also conducive to maintaining the overall stability of the temperature.

Two, is the requirement of the heat capacity stronger wok faster, metal from fast to slow ranking silver copper iron stainless steel silver, copper is also expensive, too expensive to do pot it will be wasted, and toxic aluminum copper and patina, just just heat conduction speed the price is right, will not rust iron and heat it is an ideal stainless steel heat conduction ability is not strong and it is very beautiful although aluminum as the heat conduction medium is most appropriate, so now the smokeless are basically using aluminum as the basic material, but to prevent the damage of aluminum on the human body, it will require good isolation aluminum wrapped up, it will be hard after oxidation is a process will be closed at the same time, the aluminum, surface hardness and strength to strengthen, after the processing of the original white aluminum side became black, so smokeless all you see is black Color, there is the three layer of steel pot (also called composite diamond, remember that this is not a stainless steel pot with double bottoms and is only in Chinese cooking) will be used on the hard aluminum stainless steel composite! Said the first is the requirement of pot heat capacity faster stronger.

For many workers, in a supermarket or a roadside store to buy a bag of hot milk, both nutritional supplements, but also can warm the body, can shoot two hawks with one arrow. Reporters saw in a number of supermarkets, bags of milk into the pot after heating sales, by the customer favorite. Experts, for some of the quality of packaging bags of milk, boiling water heating there is a security risk. If conditions permit, milk pot heating is the best way.

Mr. Wang took a bag just to buy milk, told reporters: "think of plastic packaging bags of milk after heating become soft, sometimes also can smell a strange smell, drink when the taste is not the same as usual." It is understood that the supermarket will be bagged milk into the hot water heating method called water bath heating method. The water bath heating method to heat the milk in the end there is no wrong? Supermarket sales staff told reporters: "the use of this way to sell hot milk is not a day two days, it should be no problem."

An expert in dairy industry for many years, the outer packing bags of milk is used in polymer materials, the main ingredient is polyethylene, will decompose and change in temperature reached 115 degrees, while the water bath heating method can be temperature controlled at 100 DEG C, under normal circumstances is safe, many consumers feel packaging soft bag packaging is a normal phenomenon after preheating. But for some of the quality of packaging bags of milk, boiling water heating there is a security risk. If conditions permit, milk pot heating is the best way.

Stainless steel pans with non stick function, the key is you have a good grasp of the temperature, when the pot is hot enough, the constant temperature can reach 160-180 degrees, not sticky food effect. We use stainless steel cooking pan stick, this is not the problem of pan, but the method of use. Stainless steel pot to prevent sticking, there are two better preheat method:
The first way: the pot on the fire heat source (not to exceed the bottom is appropriate) heating 1--2 minutes, a small amount of water thrown into the pot, until the water condensed fixed motionless in the center of the pot, the temperature has been reached. If the water was drained or jump around, the temperature has not yet reached, need to continue heating. The temperature is attained, turn the fire, pour the oil, the oil in the pan spread evenly, can be directly fried fish or other sticky food.
Second methods (the way to save more, the key recommendation): cold cold oil pan, the oil poured directly into the pot, heat the oil in the pan to produce oil lines spread to the edge of the pan, the temperature that is enough, then put cooked food. I can use one more way. However, this approach has a disadvantage, that is, the cleaning of the boiler is more trouble.

Haoxin aluminum in Yongkang Hardware Fair by the majority of stainless steel pot because of bad cleaning, and the material with different iron, so when in use, do not use the use of iron thinking, attention must be paid to the flames do not exceed the bottom of the chassis, so as not to cause the pot with yellow or black; not long time Shaoguo dry, it is easy to pan yellow. As far as possible with the use of small and medium fire, do not worry, qualified stainless steel pot with heat conductivity is still relatively good, and durability is strong, after the fire, a long time the pot body is warm. Customer welcome.
