When using the pot to pay special attention to the little porcelain pot in the past, been recognized as non-toxic tableware, but in recent years there are also reports of use of poisoning, and some beautiful porcelain tableware (glaze) containing lead, if burned when temperature enough or porcelain coating of glaze ingredients do not conform to the standard, it may make the pot contains more lead.
When in contact with food and pot, lead may overflow the glaze surface mixing with food. The national quality inspection departments at the sampling also found some ceramic pot product lead, cadmium exceeded. Lead and cadmium refers to product contain food, especially when acidic food costumes, long-term use of lead and cadmium content exceeding the product, will cause heavy intoxication, seriously affect the health, the national mandatory standards for lead, cadmium and other impacts human health indicators are strictly limited.
Use the reminder: casserole of glaze containing small amounts of lead, so the newly bought pot, it is a good idea to use 4% vinegar water immersion in boiling, thus removing most of the harmful substances. The Casserole in the interior colour, preferably wine, vinegar and acidic beverages and food. Porcelain tableware coated outer enamel products is actually a layer of enamel, with aluminum silicate material for a class, if it is damaged, it will be transferred to the food. When buying ceramic tableware that shiny enamel uniform.
Iron hot pick a look at the second hearing benefits using an iron, but is not suitable for cooking skillet acidic food cooking can iron from iron material, mainly divided into fine iron and cast iron pot. Cast iron pot it is raw iron. Skillet cooked food during stripping an inorganic iron, easily absorbed and utilized, and often use the skillet for cooking food, contribute to the prevention and treatment of iron deficiency anemia, so I've got a lot of people choose to use the traditional Pan pot.
Fine cast iron skillet possibilities how to distinguish between students and refined iron? is it legal to human health? said Miss Liao, iron is the selection of the ash iron melting model casting, heat transfer, heat evenly, but the pot ring engraving thick, rough and cracked; refined iron is made of black metal forging or hand-hammered into thin rings with a pot, heat quickly, great features. Journalists in a number of shopping malls, supermarkets, health iron price is cheaper, the container is only a raw iron 34CM, price $ 16. Press and telephone links to the King of cooking utensils co., Ltd. Zhejiang cooking, the company's Marketing Department to Miss told reporters that "raw iron also has a characteristic, when the temperature exceeds 200 ℃, disseminate students an iron will, through a thermal energy is delivered to the food temperature control in 230 ° c, while the fine iron is the temperature directly to food. For most families, it is recommended to use cast iron pot. "But she also stresses the advantages of pure iron, first, because it is made of pure iron, impurities, therefore, the comparison is not uniform heat transfer, prone to stick pot. Second, due to the use of materials, the pot can be very thin, hot temperatures can reach higher. Third, the scale is high, the surface is smooth, clean work well done.
Buy iron trick either raw or refined iron skillet, how to choose an iron? love Homestead kitchen salesmen revealed to reporters a few tips: a look at the "look", the pots are surface is smooth, but does not require the "smooth as glass", because of the casting, iron has an irregular superficial veins. There is a defect, the general part of the small hill is iron, on the quality of the pot, but pits on the pot of quality against larger, pay attention to the time of purchase. Second, "listening to" uneven pot is not good, can be purchased at the bottom of the sky, fingers resist pot concave Centre, with a hard object percussion. Pot of sound louder, more people feel vibrations, the better. In addition, the sales staff pointed out that the pot has a rust-not necessarily the quality is not good, there is a deposited rust pot description of a long time, but the longer the deposit to the pot, the better, so that the internal organization of the pot can be more stable, not easy to crack at the beginning of time.

How to cook with minimal loss of nutrition?
How to cook with minimal loss of nutrition?
Food cooking suffered a loss that cannot be completely avoided, but take some protective measures, you can make food save more nutrients.
1 sizing hang. Raw material use starch and eggs sizing hang, will facilitate a raw material in the water and nutrients from a large number of overflow, reduce losses, but not because the proteins, vitamins are a large number of decomposition.
2 due to vitamin a acid-alkali fear fear, so the dish and put some vinegar as far as possible, even if the raw material of animal origin is cooking vinegar also enables raw material is solubility in calcium, thus facilitating absorption of calcium.
3 various raw vegetables, in particular, you should clean the vegetables, then cut with reducing water soluble material losses. And should cut is cooked, it can cause the loss of nutrients less affected by oxidation.
4 cooked food, heating time to short. When you try to use cooking: hurry scrambled. The material by the open fire, quick-frying shortening one maturation time, thereby reducing the nutrient loss. According to statistics, pork, cut into strips, fried with sharp:, vitamin b, only 13% loss rate, and cut into blocks using slow fire, vitamin loss rate is up to 65%.
5 hook Ying. Then hook fluorescent one soup, some components of leaching, together with the one with the intake.
When cooking, forbidden-6. Soda can destroy the protein, vitamins and other nutrients. Therefore, in mourning for vegetables, pasta, made from raw materials and crisp black, it is best to avoid soda or soda.
◆ Quick quickly add vinegar to anxious ⒈ around quickly, avoid prolonged stew.
⒉ Note cover pots and prevent the vitamins dissolve in the water ran off with steam.
⒊ cooking should be keeping or less water, boil water, he will then drop food.
⒋ dishes add some vinegar when appropriate, crisp and delicious dishes not only allows, but also to prevent vitamin is compromised.
◆ Tips → slice the carrots, oil speculation in 6 to 12 minutes, carotene for 79 per cent; the carrot cut into blocks with the seasoning, simmer 20 ~ 30 minutes of beta-carotene is 93%; carrot cut into blocks with spices and meat, stewed with a pressure cooker 15 ~ 20 minutes of beta-carotene than saving rate of 97%.
→ Processing with bones of animal food may be appropriate to add some vinegar, which can make the animal flesh of calcareous dissolved out to dinner to intake more calcium. When the right zest of fried vegetables with vinegar, seasoning, and protects vitamin c less loss.
Food cooking suffered a loss that cannot be completely avoided, but take some protective measures, you can make food save more nutrients.
◆ A variety of cooking methods on the impact of nutrients.
Cook: Cook to casein and has partially hydrolyzed proteins, fat little effect, but will make the water-soluble vitamins (e.g., B, c) and minerals (calcium, phosphorus) are soluble in water.
Steaming: effect of steam on nutrients and minerals similar to cooking, but will not be steamed and suffered a loss.
Stewed: confit enables water-soluble vitamins and minerals dissolve in soup, only part of the vitamin road to destruction.
Marinate: pickled the same amount of time proportional to the size of nutrient loss. The longer the vitamins B and C losses, while small. But smoke and cook the food looked after to help digestion.
Brine: halogen makes food of vitamins and minerals dissolve gravy, only partially suffered a loss.
Fried: fried because temperatures are high, all of the nutrients have varying degrees of damage. Protein denaturation due to high temperature and serious, fat because of the loss of its function of killing. Saute, outside food or wrapped in a mixture of cornstarch and forms a protective film, the loss of nutrients.
Baked baking: the vitamin A, B, C are considerable losses, but also allows the fat loss. If flame grilled directly, 4 3 · food and comb carcinogen benzene.
Smoking: smoking causes the vitamins (especially vitamin C) destruction and loss of some fat, while at the same time there are 3, 4 and comb. But smoke makes food snacks.
