As a food contact material, cups need to pass LFGB (German Food and Daily Necessities Act) testing before being sold in the German market to ensure that they comply with German and European food-grade contact material standards. The following is a detailed guide for cup German LFGB food contact material testing:
1. Testing purpose
LFGB testing aims to ensure that the cup will not cause food contamination during use and protect the health and safety of consumers. Testing items cover many aspects of material composition, hazardous substance content, migration testing, and physical and chemical properties.
2. Testing process
Provide product information
Applicants need to provide detailed information about the cup, including material, usage, production batch, etc.
Fill out the application form
According to the requirements of the certification body, fill out and submit the LFGB certification application form.
Prepare samples
Provide test samples that meet the requirements for subsequent testing by the certification body.
3. Test items
Initial inspection of samples and materials
Conduct a preliminary inspection of cup samples and their raw materials, including material type, composition, production process, etc.
Sensory assessment of odor and taste transfer
Evaluate whether the cup develops any unpleasant odor or taste during use to ensure it does not adversely affect the food.
Heavy metal detection
Detect the content of heavy metal elements (such as lead, cadmium, chromium, etc.) that may be contained in the cup, and evaluate their migration under specific conditions (such as temperature, acidity, storage time, etc.). These heavy metal elements may migrate into food under certain conditions and pose a threat to human health.
Migration testing
Cup samples are subjected to different conditions (such as different temperatures, acidity, storage times, etc.) and migration tests are performed using suitable simulated liquids to assess the quality of substances in the cup that may migrate into the food.
Physical performance testing
Test the physical properties of the cup, such as density, hardness, resistance to falling, pressure resistance, etc., to ensure that it is not easily broken or deformed during normal use.
Chemical performance testing
Depending on the material and use of the cup, it may also be necessary to test the migration of other specific chemicals, such as plasticizers, bisphenol A, etc. (for plastic cups). For stainless steel cups, microbiological testing may also be required (if applicable) to ensure that the product does not become a breeding ground for microbial growth and thereby avoid food contamination.
pH test
Test the cup's pH level to evaluate its effect on the pH of your food.
Antioxidant performance evaluation
Evaluate cups for adequate antioxidant properties when in contact with food.
Solubility test
The cups are tested for solubility in specific solvents to evaluate their stability.
4. Report preparation and conclusion determination
Based on the above test results, prepare a detailed test report, including the conditions used in the test, test results, conclusions, etc.
If the cup meets the requirements of the LFGB standard, the testing agency will issue a certification mark or certificate of conformity, proving that the product meets Germany's food-grade contact material standards and can be sold in the German market.
5. Things to note
When conducting LFGB testing, it should be ensured that the testing agency and testing personnel have the appropriate qualifications and experience.
During the testing process, operations should be strictly carried out in accordance with LFGB standards and relevant regulations to ensure the accuracy and reliability of test results.
Applicants should actively cooperate with the work of the testing agency and provide necessary support and assistance.
Through the above guidelines, we can ensure that the cup passes the LFGB test before being sold in the German market to protect the health and safety of consumers.
