Ceramic rice cookers are non-toxic, because porcelain is clay fired at high temperature, as long as it is not collected in areas with high heavy metal content and large radiation, there is no problem.

However, some ceramics should be colored before firing. Generally, the coloring raw materials are all chemical raw materials, which is unsafe to some extent. It is best to buy white or white ceramics.

Purple sand is also a kind of pottery and a safe inorganic material.

The inner container made of purple sand is rich in natural trace elements such as iron, zinc and calcium, which is beneficial to human health. The cooked food has good taste, durability and good heat preservation.

How to choose a rice cooker;

1, depending on the brand:

Although the price is generally about 20% higher than that of small factory brands, the safety and quality are more guaranteed.

2. Look at the capacity:

Choose according to your eating habits, but I suggest you buy products with larger volume as much as possible.

For an automatic electric cooker, there are two most practical functions: stewing and heat preservation.

3. Digital rice cookers with reservation function are more suitable for office workers;

The price of rice cookers ranges from 100 yuan to 1000 yuan. The difference in price lies in different control panels. The rice cooker on the mechanical control panel will not automatically turn off the fire and has no reservation function, so keep an eye on the time.

Digital control panel, as long as a stewing mode is set, only need to put down the material, other temperature control is done by rice cooker, and it will automatically turn into heat preservation after stewing.

Some digital rice cookers have reservation function. For example, some office workers want to drink soup after work, put the materials in before going out, and set up an appointment function. The rice cooker will automatically turn on according to the set time, and the soup will be ready after work.
