Detection of pollutants/food contact materials: Food contact materials refer to all materials that can come into contact with food during the processing, production, packaging, storage, and transportation of food. Common materials include various plastics, metals, ceramics, glass, bamboo and wood products, such as beer bottles, vacuum plastic packaging bags, cans, etc. The necessity of food packaging and contact material testing is due to the fact that substances in food packaging may migrate into food over time and become indirect food additives. Therefore, the environmental safety of these materials that can come into contact with food directly affects the dietary safety and health of users. High quality packaging materials can ensure the proper preservation of high-quality food, while inferior packaging materials can have a negative impact on food quality. Therefore, in order to protect the interests of enterprises and consumers, strict testing must be carried out on food packaging and food contact materials. Test item 1. Sensory: Sensory testing, decolorization experiment 2. Physical and chemical indicators: Loss on drying, evaporation residue, burning residue, potassium permanganate consumption, migration of vinyl chloride monomer, phenol, formaldehyde monomer, migration of melamine monomer, n-hexane extract, acrylonitrile monomer, fluorescent substance 3. Pollutants: lead, cadmium, antimony 4. Microbial indicators: coliform group Pathogenic bacteria (Salmonella, Shigella, Staphylococcus aureus, Streptococcus hemolyticus) Partial Testing Standards GB/T 23508-2009 Food Packaging Containers and Materials Terminology SN/T 2196-2008 Inspection Procedures for Food Contact Materials SN/T 2197-2008 Determination of Acrylonitrile in Polymer Materials, Food and Food Simulants by Gas Chromatography GB 10457-2009 Plastic Self adhesive Freshness Preservation Film for Food GB/T 10004-2008 Packaging Plastic Composite Film, Bag Dry Composite Film Extrusion composite GB/T 20859-2007 Packaging bags - Determination of friction force when fully loaded GB/T 20860-2007 Packaging - Thermoplastic soft film bags - Tear propagation test method at the folding edge GB 18006.1-2009 General technical requirements for disposable plastic tableware GB/T 8169-2008 Test method for vibration transmission characteristics of cushioning materials for packaging - SN/T 0273-2002 Inspection and quarantine regulations for wooden boxes for import and export commodity transportation packaging - GB/T 23887-2009 General requirements for food packaging containers and materials production enterprises Good Practice SN/T 0263-1993 Rules for Inspection of Polystyrene foam Phase in Transport Packaging of Export Commodities SN/T 0264-1993 Rules for Inspection of Flexible Container Bags in Transport Packaging of Export Commodities GB/T 23778-2009 Cork for Liquor and Other Food Packaging
