Detection method of special transfer volume of acrylic acid in food packing materials

Abstract

The invention discloses a detection method of special transfer volume of acrylic acid in food packing materials. The method comprises the steps of sampling, pretreatment and detection of the special transfer volume of acrylic acid in pretreated target objects, Wherein the step of pretreatment comprises the processes of mixing a sample with simulated liquid which is preheated to the first specifiedtemperature to form mixed liquid, and sealing the mixed liquid; and allowing the sealed mixed liquid to stand for a specified time at the constant first specified temperature. The detection method ofthe special transfer volume of acrylic acid in the food packing materials has a low detection limit, can realize accurate detection and is simple in operation, and the used equipment is easy to obtain and low in cost and can be widely popularized.

Description

technical field [0001] The invention relates to the detection field, in particular to a method for detecting the special migration of acrylic acid in food packaging materials. Background technique [0002] In recent years, with the continuous improvement of national 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 the process of contact with food, and may release a certain amount of toxic chemical components such as heavy metals and toxic additives. Ingested by the human body, endangering human health. Our country also attaches great importance to the safety of food packaging materials. In 2016, a very comprehensive set of related regulations and testing standards was released, which standardized the safety and quality requirements and testing guidelines for food packaging materials. Plastic products are one of the most comm...

AI Technical Summary

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
