melamine is a type of triazine nitrogen-containing heterocyclic organic compound, and it’s the main raw material for melamine formaldehyde resin. at present, melamine resin prepared by condensation polymerization of melamine and formaldehyde is used in the plastics industry. sampling results showed that among the 9 batches of unqualified melamine tableware, 5 batches involved unqualified migration of melamine (4% acetic acid) , among them, the detective value of the melamine migration amount of one batch even reached 5.0 mg/kg, which was twice the standard. according to the regulations of gb4806.6-2016 national food safety standard plastic resin for food contact, the specific migration limit of melamine is 2.5mg/kg. however, when used in the food contact materials or products for infants and young children, the specific migration limit of melamine is 1.0 mg/kg.
these 5 batches of unqualified products included 1 batch from miniso (guangzhou) co., ltd., which is "kakao friends" ryan single ear apple bowl.
it is reported that melamine tableware with unqualified migration of melamine (4% acetic acid) may migrate into food during use, and there is a risk of harming human health. although melamine is not included in the "dangerous chemicals inventory", it is potentially harmful to animals, and long-term exposure or ingestion can cause disease. as early as 2017, the world health organization listed melamine as a category 2b carcinogen.
unqualified consumption of potassium permanganate
potassium permanganate consumption refers to the total amount of substances that can be oxidized by potassium permanganate when food contact materials migrate into water under certain time and temperature. it indicated the total amount of water-soluble substances that can migrate out and can be oxidized in food contact materials.
sampling results showed that 3 batches of melamine tableware potassium permanganate consumption was unqualified, and 1 batch of melamine tableware suffered serious discoloration during the decolorization test.
it is reported that the removal of inks, pigments, plasticizers, binders and other additives in food contact materials can lead to excessive consumption of potassium permanganate. if the consumption of potassium permanganate is unqualified, these harmful substances will easily migrate out into the food, which will cause harm to human health.
the unqualified products have withdrawn from the market. although the product is no longer available, we still hope that enterprise strictly control product quality.
