Inspection of food packaging containers and materials is the technical basis for ensuring the safety of food packaging. It is the guarantee for implementing the relevant packaging. For this purpose, the packaging of food materials and containers formulated by various countries is operable and corresponding testing methods have been formulated. However, in terms of the test methods developed for the test items, they can basically be divided into two major categories: one is a general test method, such as volatile residue, potassium permanganate, etc., and the other is for each specific material. The test method developed for the characteristics, such as the detection method for polyvinyl chloride monomer in polyvinyl chloride material and its container. There are 32 detection methods developed for packaging materials and packaging containers in China. The instruments used in the assay include chemical methods, gas chromatography, liquid chromatography, atomic absorption spectrophotometry, spectrophotometry, and the like.
Due to the further in-depth study on the toxicity of chemical substances, many compounds that have not previously been found to be toxic have also been found to cause harm to humans, such as the discovery that plastic additives-phthalate ester compounds have environmental estrogen-like effects. Future safety evaluation and content monitoring of food packaging materials have raised new issues. Although countries have not yet established safety standards for food-based packaging materials and food containers for compounds of this nature, it is believed that such standards will be formulated in the future, and corresponding monitoring methods will follow. This book will also provide some of the latest information.
