Accurate testing
Food contact packaging testing is crucial for assessing the risk of harmful substances being exposed to food during improper processing and storage or through the use of low-quality materials and tools.
What is Food Contact Packaging Testing
Food contact packaging testing refers to the process of checking and determining the composition of materials within food packaging according to specified testing criteria corresponding to various packaging materials.
Why is food contact packaging testing necessary
- Food packaging directly contacts food and can potentially cause harmful reactions or contamination due to temperature, food composition, or improper storage, leading to adverse health effects for consumers.
- It helps prevent the risk of poisoning incidents caused by the accumulation of substances from food packaging.
- Ensures the stable preservation of food quality within the packaging without introducing harmful substances.
Sample substrates and testing criteria
Sample substrates for testing:
- Packaging and materials made of metal in contact with food
- Packaging and materials made of plastic in contact with food
- Packaging and materials made of rubber in contact with food
- Packaging and materials made of glass, ceramics, and enamel in contact with food
Basic testing criteria:
- Packaging and materials made of metal in contact with food:
+ Determination of Cd, Pb contamination – GF-AAS method.
+ Determination of As contamination – VGA-AAS method.
+ Determination of dry residue content in various environments (ethanol 20%, acetic acid 4%, n-heptane, water)- Mass method.
+ Determination of phenol contamination – UV-VIS method.
+ Determination of Formaldehyde contamination – UV-VIS method.
+ Determination of Epichlorohydrin and Vinyl chloride contamination – GC-FID method
- Packaging and materials made of plastic in contact with food:
+ Determination of Cd, Pb content – GF-AAS method.
+ Determination of KMnO4 contamination – Titration method.
+ Determination of Pb contamination – GF-AAS method.
+ Determination of dry residue content in various environments (ethanol 20%, acetic acid 4%, n-heptane, water) – Mass method.
+ Determination of phenol contamination – UV-VIS method.
+ Determination of Formaldehyde contamination – UV-VIS method.
+ Determination of Bisphenol A (Phenol, P-t-butylphenol) content and contamination – HPLC method.
- Packaging and materials made of rubber in contact with food:
+ Determination of Cd, Pb content – GF-AAS method.
+ Determination of Zn contamination – F-AAS method.
+ Determination of Pb contamination- GF-AAS method.
+ Determination of dry residue content in various environments (ethanol 20%, acetic acid 4%, n-heptane, water)- Mass method.
+ Determination of phenol contamination – UV-VIS method.
+ Determination of Formaldehyde contamination – UV-VIS method.
- Packaging and materials made of glass, ceramics, and enamel in contact with food:
+ Determination of Pb contamination – GF-AAS method.
+ Determination of Cd contamination – GF-AAS method.
