Do not pay attention to microwave heating, be careful to poison you

There are many plastic tableware on the market that are nominally suitable for microwave ovens, but there is almost no standard for cutlery for ovens. These nominally “microwave-friendly” tableware are not necessarily safe for microwave oven heating or cooking.

And most of these utensils can only be heated for a short time under the low and medium range fire power of microwave ovens, and cannot be continuously heated or used for cooking.

  Shopping: Only those with complete logos can be trusted. When buying plastic tableware, consumers must first check whether the logo is complete, and then the product.

The surface of the product should be smooth, free of stains, impurities, scratches, cracks, etc. There should be no discoloration, discoloration, or even odors such as pungent smell.

  ”The most important thing is to look at the product logo.

“The latest standards stipulate that the product must be marked with the manufacturer’s name or trademark, material, temperature and other instructions. If the product has heat-resistant water, you cannot use a microwave oven, and you cannotRequirements such as contact with oil quality should also indicate, “The latest standards are clear, and they can be regarded as usable without the standard.”

  ”Microwave tableware” standards are being prepared. As for whether tableware made of glass, ceramics and other materials can be used at high temperature in a microwave oven, Sun Shizhen said that there may be problems with tableware of any material.

She revealed that the standard of “Microwave Tableware” is currently being prepared, and there will be requirements for tableware such as glass and ceramics.

  There are many plastic tableware on the market that are nominally suitable for microwave ovens, but there is almost no standard for cutlery for ovens. These nominally “microwave-friendly” tableware are not necessarily safe for microwave oven heating or cooking.

And most of these utensils can only be heated for a short time under the low and medium range fire power of microwave ovens, and cannot be continuously heated or used for cooking.

  The reporter learned yesterday from the Guangzhou Municipal Bureau of Quality Supervision that the first national standard for thermoplastic tableware formulated by the Guangzhou Quality Supervision and Inspection Institute-“Local Technical Specifications for Thermoplastic Tableware” has been implemented since August 1, and its overall level is in line with JapanThe standards are comparable and basically cover all thermoplastic tableware on the market.

  Status: Inconsistent logos, uneven quality, reporters visited supermarkets in Guangzhou, department stores found that there are many types of tableware for microwave ovens, but the logos are different, some indicate the use temperature and method of use, and some only indicate the use temperature.The temperature is neither marked nor used.

  The main drafter of the “thermoplastic tableware” standard and the director of the packaging inspection department of the National Packaging Product Quality Supervision and Inspection Center (Guangzhou) Sun Shizheng told reporters that Guangdong is a relatively concentrated area and a main distribution center for thermoplastic tableware manufacturing enterprises.At present, product quality differences in the market allow, and some companies seize the market with low-quality products.

  Use: Only recommended for short-time heating under 700W. Copying, “Generally speaking, the current product labeling on the market is relatively safe at 140 ° C.” However, microwave plastic cutlery that is qualified according to standards is also recommended. It is only recommendedUse under the conditions of short-term heating below 700W, unless the product is marked for cooking or other international certifications with higher requirements, it can be used under more stringent conditions.

  700W is roughly equivalent to the mid-range firepower of a microwave oven. There is a description of the output power corresponding to each firepower in the general instruction manual. For short-term heating, it means 2?
3 minutes of heating should not be used for cooking cooked food.

“Internationally, the appliances used for short-term heating and cooking are different. At present, there are two types of plastic tableware in Europe and the United States that can be used for cooking, but they are rare in the domestic market.
