At present, the kitchenware is extremely rich. Three meals a day, you stir-fry nonstick skillet, with pottery clay pot soup, rice with microwave... Experts tell us, we must choose correct and understand that a safe way to use, can make us avoid absorb too much lead, copper or aluminum, not the heavy metal poisoning.

High temperature low titanium: Fried don't use it

Controversy about the "titanium security" for a long time, in 2006, general administration of quality supervision, inspection and quarantine sampling found that ten percent titanium heavy metal exceeds bid chrome content exceeds bid. In recent years most titanium brand have improved the non-stick coating and metal cookware bonding fastness. If using a specially designed for manufacturing of kitchen utensils and appliances, non-stick coating also does not rupture or peeling coating for many years. And pieces of coating in the food also do not need to worry, because the material is inert harmless, continue to eat the body will not absorb.

Titanium security code:

1. Shoulds not be too high temperature frying. Nonstick, non-stick coating is actually a layer of film thickness around 0.2 mm, if the dry or the oil temperature of 300 ℃ or so, this film could be destroyed, some heavy metal elements will release, harmful to human body. General stir-fries, the temperature is not too high, but if the cook Fried foods, in the process of frying, has been very hot, the temperature of the pan is likely to more than 260 ℃, could easily lead to decompose harmful ingredients.

2. Don't use seriously damaged. A nonstick skillet with a little cut or Nick don't need to throw away, only in the case of large fracture, the performance of the affected should be rid of it.

3. Stir-fry nonstick skillet, don't use iron shovel, in case of destruction of non-stick coating.

Low casserole: kitchen dedicated to buy

Many people travel to buy beautiful POTS, buy back when the soup pot feel beautiful and special, it's dangerous. National quality inspection departments have found in the pottery sampling some products lead to dissolve a quantity to exceed bid. Long-term use of high levels of lead paint pot can cause lead poisoning, and small amounts of lead, can cause nerve and brain damage and weakening of the immune system. The professional cooking utensils in the supermarket or store shelves or counter purchase of pottery, security will be better.

Casserole security code:

1. Don't dress up acid food, reduce the dissolution of lead, cadmium in the acidic environment.

2. New casserole soaked with 4% vinegar water boil before use, can dissolve out most of the harmful material in advance.

3. China also lead, also had better use vinegar boiled before use.

Low microwave oven: try not to use plastic containers

Under microwave heating, the plastic container is especially easy to decompose the harmful to human body of styrene molecules, even melting, contaminated food. Even if it is marked with "available" microwave plastic container, also had better not.

Microwave safety regulations

1. Use glass or ceramic container instead.

2. Do not use plastic wrap, choose paper napkin to cover food.

Low stainless steel pot: don't install salty food for a long time

Stainless steel utensils made of beautiful and durable. But unqualified stainless steel pot can pose a safety hazard. Unqualified stainless steel pot for excess chromium commonly. Chromium is listed as one of the chemicals have a harm to human body, is one of the internationally recognized carcinogenic metals.

Stainless steel pot security code:

1. Stainless steel long-term exposure to acid, alkali, will react. Therefore, stainless steel tableware containers should not long bloom salt, soy sauce, soup, etc.

2. Can't through Chinese traditional medicine.

3. Try to use less detergent, in order to avoid corrosion on products.

Low aluminum pot: don't don't pickled friction

Have indicate that, with aluminum pan Fried food, fuel before frying oil has about 6 micrograms per gram aluminum, after frying increased to 10 ~ 20 micrograms per gram; Steaming lunch meal in the aluminum will be doubled. The argument goes: aluminum accumulation in the brain, often can cause nerve degeneration, serious influence people's behavior and intelligence. But the experts have ruled out the aluminum and there is a link between alzheimer's disease. They think that cooking using aluminum into the amount of food than other substances such as starter cultures the aluminum content of the food additives such as much less.

Aluminum pot security code:

1. Don't dress preserved food. Pickled dishes of food belong to acid alkali, easy and aluminium produces chemical reaction, generate harmful substances to human body.

2. Should not be high temperature and with metal shovel stir fry. High temperature with aluminum pan Fried cooking, or use a metal shovel, and collision and friction of aluminum pot, may make the aluminum composition is released to some extent, it is best to avoid.

Low copper: copper is never with rust

Copper is essential trace elements, but excessive copper adverse to the body, can cause nausea, vomiting, diarrhea and poisoning. Specially used for cooking TongChui generally in the lining of the pot with a layer of stainless steel, there are a few tin lining. Copper heat conduction in particular, for anything to come into contact with it, including air, water, food... Reactions are strong. Stainless steel inner layer can prevent copper came into contact with food or food and react, but there is layer of tin pot is easy to wear, and expose the copper underneath, so be careful to use.

Copper is security code:

1. Stay away from the rust. Copper rust after the "green" and "blue vitriol" are two kinds of toxic substances, so the oxidation of copper tableware, must not use.

2. Guard against breakage. Don't use no inner, or doubt lining has been damaged copper is to cook the food or clothes.

3. Careful with bronze from tourist destination, is only decoration.

4. Copper aren't going to get medicine.

Low iron pan: the most traditional and safe

POTS is China's traditional kitchen utensils and appliances, generally do not contain other chemicals, no oxidation. In the process of cooking, cooking, POTS few dissolution. And even if iron dissolution is also beneficial to human body. Who experts even believe that wok cooking is the most direct method of iron. High moisture, high acidity and cooking food, like pasta, with long normally iron content below 1 mg, but as in the iron pot cooking is almost as high as 6 mg. But also some people proposed that ordinary iron pan is easy to rust, the body to absorb too much iron oxide, namely the rust, will have to liver damage. Nutritionists believe that wok cooking for special children need iron, boys and girls and menses woman is good, but there were no iron loss risk of the elderly, and people with hemochromatosis, best don't wok-cooking.

An iron security code:

1. Brush a pan fry the dish. Every time the food finish must wash and dry pot wall, prevent rust.

2. Try not to wok to cook soup.

3. Can't fill dish in cast iron pans for the night. POTS under the condition of acid soluble iron, vitamin C.

4. Use less as far as possible when brush pot detergent. Slightly rust, usable vinegar to wash.

5. Serious rust, residue off, black wok cannot reoccupy.

Special tips:

1. The iron pan shoulds not be medicine.
