As the saying goes, if a soldier wants to do a good job, he must sharpen his weapon first. It is true that many pots are multifunctional now, and cooking and stewing are not a problem, but electric stewing is still different from them.

The power consumption of rice cookers is much smaller than that of rice cookers, and the power is generally below 300W W and less than 80 W.. If porridge and soup are stewed with slow fire, the taste and nutrition of ingredients and seasonings can be well distributed in porridge and soup, and the fragrance is very strong.

Many electric stews are made of clay and purple sand, which have the characteristics of acid and alkali resistance, large heat capacity and long heat preservation time, and have long been an ideal choice for making soups and stews.

First of all, there are two kinds of electric stews. One is traditional electric stews, that is, water and meat are put together, and with continuous heating, the water slowly evaporates.

The food stewed in the traditional stewing pot can't be stewed because of the uneven heating of the ingredients, and the high temperature will destroy the nutritional components of the ingredients, so the sealing performance is poor, and the nutritional components of the ingredients are easily dispersed and volatilized with steam.

A better rice cooker came into being. This kind of rice cooker is waterproof. The instant food is separated from water and heated separately.

Firstly, the water in the pot body is heated, and then the inner container placed in the pot body is heated by the temperature of the water, and the food in the inner container is subjected to three-dimensional circulating heat penetration conduction by using water as a medium, so that the food is heated evenly, local high temperature is avoided, and the nutritional essence is kept intact.

In this stewing method, the ingredients are heated evenly and cooked at a constant temperature of about 100, which fully and evenly releases the nutrients in the ingredients. Double-layer sealing structure ensures that the stew does not volatilize. Especially suitable for stewed bird's nest, cordyceps sinensis, fish glue and other precious tonics.

So the temperature is 100 degrees, so the cooking time is longer. This is what we call "slow stew" But the delicious stew is worth waiting for.

Secondly, in the choice of capacity, there is a general reference: the usual bowl for eating is about 0.3L, and the capacity to be purchased is about 0.3 * number of people * number of bowls (per capita).

There are many kinds of electric cooker liners, including stainless steel, ceramics, purple sand and so on. Which material is better?

Red porcelain liner rice cooker

Natural purple sand contains essential trace elements such as iron, calcium, sodium and zinc, which is beneficial to human body. The special microporous structure of purple sand makes it have good air permeability, so it can store food well and keep food fresh.

In the long-term cooking process, the purple sand liner will not react chemically with food at high temperature, but also decompose oil, which can dissolve the greasy when stewing soup, make the meat crisp but not rotten, taste delicious but not greasy, and reduce cholesterol.

Ceramic liner electric rice cooker

In the rice cooker industry, the ceramic liner can compete with purple sand. Especially the relatively noble white jade porcelain liner has almost become the standard of high-end rice cookers.

According to analysis, white jade porcelain is similar to purple sand and contains trace elements beneficial to human body. However, compared with ceramic materials such as purple sand and white jade porcelain, it has higher density and smooth and delicate surface after high temperature firing. It is difficult for soup to penetrate into the liner material, thus avoiding the phenomenon of "cross-flavor".

The rice cooker caters to the traditional eating habits of China people, so it has been sought after by consumers in the market in recent years. In order to meet the needs of consumers, the rice cooker industry is also constantly innovating, especially the liner that is in direct contact with food. Enterprises gradually introduce health products represented by inner containers such as purple sand, white porcelain and glass. It is understood that there are hundreds of brands of rice cookers at present.

Influenced by China's health concept, consumers also have many preferences for the material of the inner container of rice cookers, which makes it different from other household appliances. Therefore, the new standard should not only pay attention to the electrical safety index of products, but also pay attention to the safety of materials in contact with food. According to reports, the industry standard for rice cookers to be drafted will be divided into two categories according to the material of the liner, namely, metal liner and non-metal liner, and corresponding specifications will be formulated respectively, and safety considerations will be the key content of the standard. The teapot that once made a lot of noise will also be included in the new standard.

Electric cooker, slow cooker, electric pressure cooker, purple casserole. Are there any uniform rules for children? A few days ago, industry standards for rice cookers, including the above products, were formulated and started. Ma Dejun, Secretary-General of the Technical Committee for Standardization of Electrical Appliances, said: The standard for electric cookers will be completed and implemented within one year, and the standard will focus on the safety of liner materials.

In May last year, CCTV's Weekly Quality Report revealed that some manufacturers in Hunan, Guangdong and other places used ordinary clay to add chemical pigments such as iron red powder and manganese dioxide to prepare raw mud for "teapot". After the incident was exposed, the teapot was removed from the shelves all over the country, and some brands stopped production. Influenced by the traditional concept of health preservation, Chinese consumers have many preferences for the materials of rice cookers. At present, rice cookers on the market are made of purple sand, fine porcelain, metal, glass and so on.

According to the announcement issued by the Ministry of Industry and Information Technology, 35 household appliance standards will be revised in 20 1 1 year, of which 2 1 item is newly formulated and 41item is revised, and the rice cooker industry standard is among the newly formulated plans. Han Run, vice president of Jiuyang, who is the leader of this standard drafting group, said: "Previously, the rice cooker industry has always followed the standard of liquid heaters, and there is no unified industry performance standard as the market' threshold'." It is reported that in the first draft of the industry standard for rice cookers, rice cookers are divided into two categories according to the liner material: metal liner and non-metal liner. The key is to ensure the performance safety and food safety of the inner cooker.

Material introduction of rice cooker liner;

Polytetrafluoroethylene is the main component of Teflon.

Teflon is the general name of all hydrocarbon resins developed by DuPont (commonly known as "Teflon" registered by DuPont in the market), including polytetrafluoroethylene, perfluoroethylene propylene and various polymers; Because of its unique and excellent heat resistance (180℃ ~ 260℃), low temperature resistance (-200℃), self-lubrication and chemical stability, it is called "corrosion-resistant, never-sticking PTFE".

In the process of manufacturing PTFE, ammonium perfluorooctanoate needs to be added as raw material to form the final polymer.

Ammonium perfluorooctanoate: It is the ammonium salt of perfluorooctanoic acid. Perfluorooctanoic acid is a soap-like substance, which can be used to make non-stick surfaces and various consumer goods, including non-stick pans, non-stick carpets and pizza boxes. Exposure to perfluorooctanoic acid may lead to cancer or affect the reproductive function of mice.

Most of them are right, but the important point is that the decomposition temperature of ammonium perfluorooctanoate is relatively low, starting from 130℃, while Teflon paint is baked at 380℃, so it is impossible to contain ammonium perfluorooctanoate in the paint. If you can detect ammonium perfluorooctanoate in the coating, you are from all over the world. In addition, the black crystal is indeed an improved Teflon, and the material is the same. However, due to the existence of stainless steel particles during processing, the hardness is much higher, and a shovel can be used. In fact, the Teflon incident has made everyone nervous because of China's one-sided report.

Ammonium perfluorooctanoate is not the main component in PTFE coating, but an auxiliary agent in PTFE resin, accounting for about 2%, and less than 1% in the coating, but no matter how much, the coating after high temperature treatment does not contain it. In fact, this problem is because DuPont is surrounded by the United States and demands to reduce the atmospheric emissions of ammonium perfluorooctanoate year by year, but he ignores it, while other companies such as 3M are doing better, so they point the finger at DuPont, which is an environmental pollution problem. So many factories all over the world are making similar Teflon, such as Hua Fu in the United States, Daikin in Japan and Nobel in Europe. Why didn't they become defendants?

In addition, the paint will not decompose in the body after falling off, so it has no effect. The decomposition temperature of Teflon paint is above 4 15℃.
