According to the latest report released by the Chinese National Health and Family Planning Commission, titled "Hygienic Standard for Stainless Steel Tableware Containers" (GB 4806.9-2016), food-grade stainless steel must undergo a migration test to ensure the safety of consumers.
The migration test involves immersing the stainless steel material in a simulated food solution, usually an acidic one, for a specified period of time. This test aims to determine whether any harmful elements present in the stainless steel container are released into the food.
The standard specifies that if the solution does not show precipitation of the five harmful substances beyond the permissible limits, the stainless steel container can be classified as food-grade. This ensures that stainless steel tableware used in food preparation and consumption is free from any potential health hazards.
The five harmful substances being tested in the migration test include heavy metals like lead and cadmium, as well as arsenic, antimony, and chromium. These elements, if present in excessive amounts, can contaminate the food and have detrimental effects on human health.
Lead is a highly toxic substance that can accumulate in the body over time and cause severe health issues, especially in children. Cadmium, another heavy metal, is carcinogenic and can lead to kidney and lung damage. Arsenic is known to be a potent carcinogen, while antimony has been linked to respiratory disorders. Chromium, although an essential trace element, can become harmful in higher concentrations, leading to skin allergies and respiratory problems.
The migration test is crucial in ensuring the safety of stainless steel tableware, as it certifies that the materials used do not leach harmful substances into the food that comes into contact with them. Companies manufacturing stainless steel tableware must comply with this standard to ensure the health and well-being of consumers.
The Chinese National Health and Family Planning Commission, along with other relevant authorities, regularly monitors and enforces compliance with this standard. It is also essential for consumers to be aware of the food-grade label and purchase stainless steel tableware from trusted sources to avoid counterfeit or substandard products.
In conclusion, the migration test mandated by the "Hygienic Standard for Stainless Steel Tableware Containers" is a critical step in guaranteeing food safety. By ensuring that stainless steel tableware passes this rigorous test, consumers can have peace of mind knowing that the products they use daily meet the necessary standards and do not pose any health risks.
