Rice cooker, almost every family has, for people who love to eat rice, it is more every day to use. However, have you paid attention to the precautions for using rice cooker?
"How should I clean my rice cooker liner on a daily basis?"
"Can I continue to use it even if the liner coating is peeling off or damaged?"
How can I use my rice cooker safely and cook a good meal? Take a look at the professional answer.
When buying a rice cooker, we tend to pay attention to its style, volume, function, etc., but often ignored and rice "zero distance contact" of the inner liner.
Rice cookers are mainly composed of two major parts: the outer shell and the inner liner. Since the inner liner is in direct contact with the food, it can be said to be the most important part of the rice cooker and plays a decisive role in the purchase of rice cookers.
"Currently, the more common inner liners of rice cookers on the market include aluminum inner liners, alloy inner liners, stainless steel inner liners, ceramic inner liners, and also glass inner liners." The most common pairing is aluminum liner + coating.
Because metallic aluminum has the characteristics of uniform heat and fast heat transfer, it is the preferred material for the inner liner of rice cookers. Aluminum inner liner can not be directly contacted with food, so generally the surface of the inner liner made of this material is attached with a coating, mainly divided into Teflon coating (also known as PTFE) and ceramic coating. Its main function is to prevent the bottom from sticking to the pot and to make it easy to clean.
"The coating on the inner liner of the rice cooker is inherently resistant to acids and alkalis and is not easily broken down by high temperatures. Sprayed on the aluminum inner liner, it plays a protective and anti-sticking effect." According to experts, the safe use of the commonly used Teflon coating has an upper limit of 250 ℃, and the highest temperature of daily use of the rice cooker is about 180 ℃, so under the premise of the inner liner coating has not fallen off, the normal use of the inner liner of the rice cooker will not cause harm to the human body, and there is no need to worry.
However, as the rice cooker is used for a long time or improperly operated on a daily basis, the inner liner may "lose paint", which is likely to be a health risk.
First of all, the rice cooker liner "paint" is more likely to stick to the pot, long time sticking to the liner on the high temperature heating of food is easy to scorch, producing carcinogens such as acrylamide. At the same time, the subsequent cleaning is also quite laborious, there are health hazards. Even if the coating off seriously, the inner liner is equivalent to an "aluminum gallon", this time continue to use for a long time, the aluminum in the liner may be more with the food into the body.
Since aluminum is not a micronutrient required by the human body, long-term intake of aluminum may cause neurological disorders and increase the risk of Alzheimer's disease in adults. It also affects the body's absorption of phosphorus, calcium and vitamin D, causing bone damage and deformation, leading to diseases such as chondropathy and osteoporosis. Compared with adults, children have a lower tolerance for aluminum, and the harm is even greater.
In addition, some people in order to facilitate and save time, a pot for multiple uses, often use the rice cooker cooking and long-term storage of sweet and sour pork, hot and sour soup and other heavy acid and heavy vinegar soup dishes. Acidic substances in food can further accelerate the exposure of "aluminum gallbladder" in the dissolution of aluminum, does not meet food safety standards, there are food safety risks.
When the coating of the inner liner comes off, it will cause the rice to be heated unevenly, resulting in problems such as sticking to the pan, muddy bottom, dry pan, etc., which will affect the usage effect and the nutritional value of the cooked rice. Moreover, most of the inner liners with coatings are made of aluminum alloy, and after the coating falls off, it will cause the aluminum substrate of the inner liner to be exposed, resulting in the aluminum substrate coming into direct contact with the food.
Therefore, if you find that the rice cooker inner liner coating has obvious scratches or has fallen off in pieces, it is best to stop using it immediately and replace the product in time.
Ceramic inner liner may be a better choice than metal coating inner liner
The smooth surface of the ceramic liner will not react with the ingredients, which can ensure the flavor and texture of the rice.
Ceramic liner also has good heat preservation performance, long service life, can effectively prevent the loss of nutrients in the food.
However, the ceramic inner liner is heavy and fragile easy to break, so you need to pay attention to be careful to carry and put down gently
Ceramic liner rice cooker, suitable for consumers who have higher requirements on the quality of rice.
