Problems solved by technology
Plastic products are one of the most common and widely used materials for food packaging since the 1960s, but due to monomer residues in the synthesis of polymer materials and relatively low-molecular additives added in the molding process, they do not meet the requirements The plastic material will remain or migrate out of toxic and harmful monomers, which will change some characteristics of the food or cause harm to the human body
This technology fills the gap in the national standard method. In the "GB 4806.6-2016 National Food Safety Standard", it is pointed out in the requirements for the use of methyl acrylate polymer materials in food packaging materials in plastic resins for food contact that the monomer migration of this material The amount (acrylic acid) limit is 5mg / kg, but the relevant industry has not yet established an official method for the detection of this substance

Abstract
The invention discloses a method for detecting the migration of acrylic acid in food packaging materials, comprising the steps of: sampling; pretreatment and detection of the migration of acrylic acid in the target after pretreatment; wherein, the pretreatment step includes: combining the sample with preheating The simulating liquid at the first designated temperature is mixed to form a mixed liquid and sealed; the sealed mixed liquid is kept at a constant temperature at the first designated temperature for a designated time. The method for detecting the migration of acrylic acid in food packaging materials of the present invention has a low detection limit, can accurately detect, is simple to operate, and the equipment used is easy to obtain, low in cost, and highly popularizable.
Description
technical field [0001] The invention relates to the field of detection, in particular to a method for detecting the migration amount of acrylic acid in food packaging materials. Background technique [0002] In recent years, with the continuous improvement of people's attention to food safety issues, the safety of food packaging materials has also received extensive attention. Food contact materials and products may affect the smell, taste and color of food during contact with food, and may release a certain amount of toxic chemical components such as heavy metals and toxic additives. If ingested by human body, it will endanger human health. Our country also attaches great importance to the safety of food packaging materials. In 2016, a very comprehensive set of relevant regulations and testing standards were updated and released, which standardized the safety and quality requirements and testing guidelines of food packaging materials. Plastic products are one of the most ...
