Inferior melamine tableware may release melamine

[Abstract]:
最近,国际食品包装协会常务副会长兼秘书长董金狮称劣质的仿瓷餐具加热后可能释放三聚氰胺,危害儿童健康,呼吁修改国标。

Recently, Dong Jinshi, executive vice president and secretary general of the International Food Packaging Association, said that inferior melamine tableware may release melamine after heating, which is harmful to children's health and calls for the revision of the national standard.

 

Dong Jinshi told reporters: "My first reaction to the melamine incident in Sanlu milk powder was that there was a problem with the packaging. Of course, the result was worse than we thought." For professional sensitivity, to understand whether other packaging materials have such safety hazards. . The melamine tableware we sampled has a safety hazard.

 

International Food Packaging Association and Beijing Kaifa Environmental Technology Consulting Center were on November 13th, 2008 at No. 55-61, 8th Floor, Tianyi New Mall, 4B105-106, 4th Floor, Wantong Shopping Mall, B-18, Linglong Tower Market. There are a total of five melamine tablewares in the five markets of the second floor of the Yuegezhuang Market, Food Hall on the second floor of the Yuegezhuang Market, and the No. 8 C Zone, the first floor of the logistics port of Jinxiu Dadi Market. The samples are sent to the National Environmental Protection Product Quality Supervision and Inspection Center. The evaporation residue (water), potassium permanganate consumption, formaldehyde (4% acetic acid), and discoloration were examined.

 

Dong Jinshi introduced that melamine tableware, also known as melamine tableware and melamine dish, is made by melamine resin powder heated and pressed. Its main features:

 

1. Excellent solvent resistance;

 

2. The surface of the product has the characteristics of flatness, non-toxicity, odorlessness, resistance to falling, and automatic arc extinguishing;

 

3, widely used in tableware, daily necessities and other aspects.

 

Main technical indicators of melamine tableware: 1. Water evaporation residue: ≤10mg/L; 2. Potassium permanganate consumption: ≤10mg/L; 3. Formaldehyde: ≤30mg/L; 4. 65% ethanol decolorization test: Negative; 5, product heat resistance, impact resistance, bending resistance and other performance and health indicators can meet the requirements of GB9690-88 and QB1999-94.

 

By purchasing the sampling situation through the market and analyzing it based on the test results, the following conclusions can be drawn:

 

1. In two markets, the products in the two markets were unqualified, and the pass rate was only 60%. The unqualified market is the counter at No. 55-61, 8th Floor, Tianyi New Mall, and 4B105-106, 4th Floor, Vantone Market. The quality problems that exist are mainly due to serious product fading and excessive formaldehyde. The formaldehyde content of melamine tableware in Tianyi New Mall is as high as 55.0mg/L, which is much higher than the national standard of 30mg/L, which is extremely harmful.

 

2. The merchants cannot provide the quality and safety production license (QS certificate) of the product manufacturer during the purchase process.

 

3. The melamine tableware in the five markets is only the binaural bowl (blue flower) of No. 8 in the underground area of ​​the Jinxiu Dadi Market Logistics Port. There is no enterprise information in the other.

 

4. During the purchase process, the merchants only issue receipts, and the invoices are issued by the market. Most of the invoices do not have the specific information of the sellers and products, which brings difficulties for the future tracing of quality problems.

 

In reality, melamine tableware is particularly popular with children and the elderly because of its resistance to falling and microwave heating. Everyone thinks that melamine tableware is a versatile tableware, and everything can be done, how can it be done, who can do it, how long it will take. Dong Jinshi reminded that these understandings are all wrong. In fact, if the melamine plastic raw material resin is not well polymerized, melamine remains and the melamine molecule is released at a high temperature. However, the standard does not clearly state that the company's product specifications are not stated, consumers can only passively use, chronic poisoning.

 

Dong Jinshi pointed out that the discoloration of melamine tableware products indicates that the color masterbatch used in the products may be toxic and harmful industrial grade. The raw materials used may be recycled waste or industrial materials, which pose serious safety hazards to human health. Consumers, especially children, are advised not to use overly bright melamine tableware, especially on the inside, to prevent the harm caused by bright colors.

 

It is understood that the melamine tableware is now based on the standard issued on August 10, 1988 by the Ministry of Health of the People's Republic of China "Sanitary Standard for Melamine Molding for Food Packaging" GB9690-88.

 

Dong Jinshi believes that the GB9690-88 standard has been implemented since June 1, 1989, and has not been revised since 20 years. It cannot reflect the current product quality and market application in China. For example, the standard only has the evaporation residue standard for water, and there is no standard for n-hexane, acetic acid and ethanol. That is to say, melamine tableware cannot be used for oily foods, acidic foods and alcoholic foods, but there is no supervision in reality. The department carries out the requirements in this regard, and the company does not have any instructions on the product description.

 

Due to the inconsistent use conditions and standard requirements, it has brought difficulties to government supervision and monitoring, creating “good” conditions for the survival of unscrupulous production enterprises and inferior products, which has caused huge security risks to consumers.

 

More importantly, the carcinogen formaldehyde limit value is not more than 30mg / L, too loose, very harmful. Formaldehyde (HCHO) is a colorless, irritating and water-soluble gas. It has the function of coagulation protein, and its 35% to 40% aqueous solution is commonly known as formalin. Formaldehyde is a highly toxic substance, and formaldehyde ranks second in the priority control list of toxic chemicals in China. The World Health Organization has determined that formaldehyde is a carcinogen! The greatest danger to humans is that it is accompanied by a long cycle of human beings and is constantly released.

 

Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, causing genetic mutations in nasopharyngeal cancer, colon cancer, brain tumors, menstrual disorders, and nucleus, and even lead to pregnancy syndrome, causing neonatal chromosomal abnormalities and leukemia. Among all contacts, children and pregnant women are particularly sensitive to formaldehyde and the harm is even greater.

 

The limited amount of formaldehyde in the "Sanitary Standard for Melamine Moldings for Food Packaging" GB9690-88 allows up to 30mg/L, which will cause great harm to consumers' health. In developed countries, the requirement for formaldehyde in food packaging materials is less than 1 mg/L or may not be removed.

 

In this regard, Dong Jinshi suggested that the competent department of national standards should update the standards of melamine tableware as soon as possible in combination with international and domestic conditions, and formulate more stringent and reasonable standards, especially the indicators for evaporation of n-hexane, acetic acid and ethanol. Melamine precipitation indicators are added to ensure the health of consumers.

 

At the same time, the index of formaldehyde should be reduced to the limit value, it is recommended to be below 5mg / L or more stringent. The product should be subjected to an acute toxicity test, and a production license can be issued after the pass.

 

Relevant departments shall strengthen the supervision of the handling of production licenses and the use of licenses. According to the provisions of the No. 123 Document of the General Administration of Quality Supervision, Inspection and Quarantine, from January 1, 2008, plastic packaging, containers and tools such as plastic bags, snack boxes, cling film and plastics for foods that have not obtained production licenses. 39 kinds of products such as cutting board, woven bag, oil drum and melamine tableware shall not be produced or sold, and the offender shall be strictly enforced in accordance with the State Council's Prime Minister's Order No. 503, with a minimum fine of 100,000 yuan. At present, there are nearly 1,000 melamine tableware production enterprises in the country, and there are only 20 enterprises that actually obtain production licenses, that is to say, only 2% of enterprises are legally produced, and 98% of enterprises are illegally producing.

 

Dong Jinshi believes that the formulation of standards should be fully funded by the state, drafted and verified by the government standard management department, relevant experts, production enterprises and users. Do not let enterprises take money to participate in standard setting and prevent the standards from being commercialized. The hidden danger.

 

For the sale of food packaging, containers and tools, it is recommended that the market start-up department and the industrial and commercial departments designate and supervise to prevent unfair competition caused by chaotic buying and selling to the survival of formal enterprises. Warnings, confiscation of products and disqualification of sales may be imposed on defaulting merchants.

 

For consumers, Dong Jinshi suggested that it is best to go to large shopping malls and supermarkets to buy melamine food packaging products. According to the survey, most supermarkets have guaranteed purchase channels and quality, and have obtained production licenses from production companies, which have good traceability. The bottom of the regular melamine tableware has company details and production licenses and serial numbers.

 

You can put the melamine tableware you just bought in boiling water and vinegar for two to three minutes, or soak it in vinegar for 2 hours at room temperature, so that harmful substances such as formaldehyde, melamine and heavy metals can be precipitated. Security. In addition, care should be taken not to hold acidic, oily, alkaline foods or beverages for a long time. In particular, do not put more oily foods in melamine tableware to heat the microwave oven to prevent the production of highly toxic cyanide.
