Recently, Lutron Analytical Instruments released a qualitative and quantitative analysis method for the migration of pollutants in food packaging paper by using solid phase microextraction-gas chromatography (SPME-GC). Through automated operation, the method runs fast, stable and saves a lot of manpower. Food packaging is a key component of the food industry, with a wide range of packaging materials, including plastics, paper, metal and glass. It protects food from damage while keeping food fresh and free of microbial degradation. However, food packaging materials can also cause food spoilage. Food packaging materials are regulated by relevant regulations around the world. The latest EU/202/2014 regulations impose restrictions on plastic packaging that may come into contact with food: not only chemical substances that can be transferred to food by packaging materials. The maximum amount also clarifies the chemical substances prohibited in food packaging materials, as well as the limits of related substances in food and packaging materials. Over the past 20 years, researchers have published a variety of test methods for effective monitoring and analysis of packaged migrations. In general, there are two main categories: The first is to assume that each compound in the packaging material is 100% transferred to food. The final form of the packaging material itself is analyzed. The second type simulates the food product and the packaging material in contact under a specific period of time and a specific environment under simulated conditions, and then analyzes the migration of the compound in the package to the food. Food packaging papers can be made from virgin paper, recycled paper, or a mixture of the two. Recycled cardboard is more likely to contain a wide range of hazardous contaminants from degradation, including printing inks, coatings, and adhesives. This test uses solid phase microextraction (SPME) and gas chromatograph (GC) techniques, using the first method described above, for 12 representative possible migrations in food packaging cardboard (o-benzene) Quantitative analysis was performed on volatile and semi-volatile substances such as diformate, photoinitiator, phenol and odor components. In this experiment, the GC-9870 gas chromatograph was equipped with an AHS-6890 autosampler and solid phase microextraction SPME (SPME NL: 50.5 mm) for test analysis. GC Thermo Separation imported TraceGOLD TM TG-5SilMS column (30m × 0.25 mm × 0.25μm, P / N). This experiment used an internally validated test method to quantify 12 migration contaminants that may have been introduced by cardboard. The method applied the fully automatic SPME technology, which effectively improved the laboratory test throughput. Internal method validation was performed in accordance with the IUPAC/AOAC uniform operating procedures and confirmed to be suitable for monitoring hazardous contaminants in paper jams that may come into contact with food.
