Project background: This project belongs to the standardization science and technology field and the modern service industry and informatization field of the inspection and testing industry. Kitchen utensils and packaging are a type of daily consumer goods that are very closely related to people's lives. Various products contain a large number of hazard factors. More and more strict limit regulations for these harmful substances are constantly introduced and updated at home and abroad. However, my country's testing technology and standard system in this field are seriously lagging behind, hindering the improvement of product quality and industrial technology progress. At present, developed countries attach great importance to vigorously promoting advanced technologies and setting up trade barriers through technical standards. Therefore, it is very necessary for my country to accelerate the research and development and standardization process of advanced technologies in this field. Main technical contents: Hazardous factors in kitchen utensils and packaging mainly come from residues of synthetic monomers and abuse of harmful additives during processing. The target substances have complex sources, wide variety, different characteristics, low content, and complex substrates. In response to my country's backwardness in inspection technologies and standards in this field, this project has developed a series of advanced inspection technologies that are currently generally lacking and urgently needed, and promoted the standardization of the established technologies in stages and applied them to regulatory agencies, third-party inspection agencies, and production enterprises., to achieve product quality control, compliance judgment and risk monitoring, thereby maximizing the protection of consumer health and safety, and promoting industry technology improvement and trade facilitation development. (1) Using precision instruments such as gas chromatography-tandem mass spectrometry, combined with new pretreatment technologies such as accelerated solvent extraction, fully automatic headspace analysis, and solid phase microextraction, a series of fast and accurate hazard factors such as PFOA and plasticizers in complex substrates have been established. Detection methods, and promoted the standardized application of the established methods, successfully transformed into national standards and industry standards, and solved the problem of missing and backward existing standards;(2) New nanocomposites such as magnetic graphene and molecularly imprinted polymers were prepared and applied to the development of rapid screening and detection sensors for trace amounts of bisphenol A and aromatic amines, meeting the low limit requirements of new foreign regulations and significantly improving port supervision. Flux;(3) Formulate a series of national standards and industry standards for migration test conditions guidelines, and independently developed a migration test immersion device, standardizing unified operating procedures and evaluation basis for the country; Furthermore, based on Fick's Law and migration detection standards, a mathematical fitting model and software for hazard factor migration are established to partially replace traditional experimental testing, form an environmentally friendly testing technology, and provide support for national inspection and supervision. Technical and economic indicators and intellectual property rights: This project: (1) The new hazard factor detection technology developed has been formulated into 9 industry standards, 5 national standards have been approved, 1 invention patent has been authorized, 14 papers in core Chinese journals have been published, and 2 books have been published;(2) The nano-sensing detection technology developed has published 3 SCI papers, 1 invention patent has been authorized, and 1 invention patent has been applied;(3) Research migration test conditions and formulate a series of 1 national standard and 4 industry standards; the migration test device and pretreatment device developed were authorized by 4 utility model patents, and the mathematical model developed was developed by 1 software copyright. Application promotion and benefits: The standards formulated by this project have been promoted and applied in inspection and quarantine systems, production enterprises and the national testing industry, effectively ensuring the quality of products in import, export and domestic markets, and protecting the health and safety of domestic and foreign consumers; It breaks down technical barriers set by foreign regulations and reduces the risk of returning export products. During the promotion and application period from 2010 to 2014, nearly a thousand batches of export products were inspected in Shanghai, with a value of tens of millions of dollars, directly and indirectly saving enterprises. Economic costs promote the healthy development of the production industry and obtain good social and economic benefits; cultivate 3 senior professional titles to contribute to the cultivation of technical talents.
