As a cooking tool that comes into direct contact with food, non-stick frying pans need to undergo China GB4806 food contact material testing. This testing is to ensure that nonstick frying pan materials, when in contact with food under recommended conditions of use, do not migrate into food at levels that would harm human health.
China GB4806 testing project
1. Evaporation residues in different food simulation liquids: This test is to evaluate the amount of substances that may be released from frying pan materials in simulated food environments. These substances may migrate into food, so their detection is critical.
2. Potassium permanganate consumption: This project is used to detect oxidizable substances that may exist in frying pan materials. These substances may react chemically with food and affect food quality.
3. Heavy metals (measured as lead): Heavy metal detection is an important part of food contact material testing, because excessive heavy metals may have a serious impact on human health.
4. Decolorization test: This test is used to detect the decolorization of frying pan materials under specific conditions to evaluate its color stability and potential impact on food.
5. Dissolution test of heavy metals: such as the detection of dissolution of heavy metals such as lead, cadmium, arsenic, antimony, nickel, etc. The dissolution of these heavy metals may cause harm to human health.
6. Residues of toxic and harmful monomers: For chemical substances that may be used in frying pan coatings, such as vinyl chloride monomer, acrylonitrile monomer, etc., detect their residual amounts to ensure their safety.
7. Microbial testing: In order to ensure that the frying pan will not become a breeding ground for microorganisms during use, microbial testing is required to ensure its hygienic safety.
