As a food contact material, ceramic cups need to pass LFGB testing before being sold in the German market to ensure that they meet Germany's food-grade contact material standards. LFGB testing is a comprehensive evaluation process that includes testing of material composition, hazardous substance content, migration testing, and physical and chemical properties.
1. Detection steps
1. Sample preparation
Random selection: Randomly select standardized samples that meet the specified requirements from mass-produced ceramic cups.
Sample processing: According to the test standards, the samples are cleaned, dried and other processing processes to ensure the consistency of the test conditions.
2. Material identification
Component analysis: Conduct component analysis on the raw materials of the ceramic cup to understand its composition.
Physical property testing: including testing of physical properties such as density and hardness to evaluate the basic properties of the sample.
3. Hazardous substance detection
Heavy metal detection: focus on detecting heavy metal elements such as lead (Pb), cadmium (Cd), cobalt (Co) that may be contained in ceramic cups. These heavy metals may migrate into food under certain conditions and pose a threat to human health.
Testing method: Usually includes dissolution testing, which tests the amount of heavy metals leaching out in a simulated food environment.
Specific requirements: For samples with patterns within 2cm of the cup edge, additional lead, cadmium, and cobalt dissolution testing is required.
4. Migration testing
Simulated environment: Place the sample under different conditions (such as different temperatures, acidity, storage time, etc.), and use appropriate simulated liquids for migration tests.
Migrant mass: Tests the mass of substances in a ceramic cup that may migrate into food under specific conditions.
5. Chemical property testing
pH value: Test the pH value of the ceramic cup to evaluate its impact on the pH of food.
Antioxidant properties: Evaluate whether ceramic cups have sufficient antioxidant properties when in contact with food.
Solubility: Test the solubility of a ceramic cup in a specific solvent to evaluate its stability.
6. Physical property testing
Heat resistance: Test the stability of ceramic cups under high temperature conditions.
Oil Resistance: Evaluate the durability of ceramic cups when in contact with fatty foods.
Mechanical strength: Test the mechanical strength of ceramic cups, such as resistance to pressure, resistance to falling, etc.
7. Sensory evaluation
Odor and taste transfer: Evaluate possible odor and taste transfer during use of the ceramic cup to ensure it does not adversely affect food.
2. Test report
Prepare report: Prepare a detailed test report based on the above test results, including the conditions used in the test, test results, conclusions, etc.
Conclusion: If the ceramic 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 the German food-grade contact material standards and can be sold in the German market.
