As a common food contact material, stainless steel mesh needs to be certified by the U.S. Food and Drug Administration (FDA) to ensure its safety when in contact with food. The following is detailed information about the U.S. FDA food contact material certification of stainless steel mesh:
I. Certification Overview
The U.S. FDA food contact material certification refers to ensuring that materials in contact with food do not release harmful substances during use, thereby ensuring food safety. For stainless steel mesh, the certification process mainly involves testing of material safety, chemical composition, physical properties, etc.
II. Certification Standards
According to FDA regulations, stainless steel mesh needs to comply with the following standards and regulations:
- 21 CFR Part 174-178: General provisions for food contact materials.
- 21 CFR Part 175.300: Provisions for food contact surface coatings.
- 21 CFR Part 176.170: Provisions for paper and paperboard.
- 21 CFR Part 177.2600: Provisions for polymeric substances.
III. Certification steps
1. Determine the testing standards
According to FDA regulations, stainless steel mesh needs to comply with relevant standards and regulations. These standards and regulations may involve aspects such as material safety, chemical composition, physical properties, etc.
2. Choose the appropriate testing method
Different testing methods may be used for different materials and product characteristics. For example, chemical composition analysis, migration testing, toxicity assessment, etc. may be required.
3. Prepare samples
Prepare a sufficient number of samples that meet the requirements according to the requirements of the test method. Make sure that the samples are not processed in any way to reflect the true situation of the product.
4. Submit a test application
Submit the samples and test application to a testing agency approved by the FDA. The application should include detailed information about the product, the purpose of the test, the applicable standards, etc.
5. Conduct the test
The testing agency will test the samples according to the submitted test application and applicable standards. This may include chemical analysis, physical property testing, toxicological assessment, etc.
6. Obtain the test report
The testing agency will issue a detailed test report stating the test results of the sample and whether it complies with the relevant FDA standards and regulations.
IV. Special requirements for stainless steel mesh
1. Material safety
Stainless steel mesh should comply with the FDA's "Food Contact Materials Regulations" (21 CFR 179.1), proving that it is safe and harmless, and is not likely to cause food contamination or affect human health.
2. Chemical composition analysis
Detect the chemical composition of the stainless steel mesh to ensure that it does not contain harmful substances, such as the dissolution test of heavy metals (lead, cadmium, chromium, nickel, arsenic, etc.).
3. Corrosion resistance
Evaluate the corrosion resistance of stainless steel mesh in food contact environment to ensure that it will not corrode under normal use conditions.
4. Surface treatment
Check the surface treatment method of stainless steel mesh, such as polishing, electrolytic polishing, etc., to ensure that the surface is smooth, easy to clean and disinfect, and has a low friction coefficient.
5. Migration test
Carry out water extraction, 8% ethanol extraction, 50% ethanol extraction, n-heptane extraction and other tests to ensure that the stainless steel mesh will not release excessive chemicals into the food under simulated food contact conditions.
6. Physical performance test
Evaluate the hardness, toughness, tensile strength, impact resistance, wear resistance, etc. of the stainless steel mesh to ensure that it will not be damaged or deformed during normal use.
7. Microbiological test
Detect whether there are pathogenic bacteria or other microorganisms on the surface of the stainless steel mesh to prevent food spoilage or consumer infection.
V. Labeling and certification requirements
FDA requires manufacturers of food contact materials to indicate relevant information on the product, such as material composition, production date, shelf life, etc. These requirements ensure the safety and compliance of stainless steel mesh as a food contact material to protect the health of consumers.
Through the above steps, the stainless steel mesh can obtain the US FDA food contact material certification, thereby ensuring its safety when in contact with food.
