Safety fingerprinting traceablility method for food packaging material

Abstract

The invention provides a safety fingerprinting traceablility method for the food packaging material and belongs to the field of a safety analysis and traceablility method for packaging materials. According to the method, firstly, a fingerprint database is established for one or more types of materials at a lower level selected from the following four types of materials: membrane materials, adhesives, printing ink and resin. Based on a method the same with the above operation, the fingerprints of subsequent to-be-measured batches of products are established, and the chemical structure peak or data of the fingerprint information are compared with the fingerprint information of qualified products filed in the fingerprint database of corresponding products. On the condition that the above two types of fingerprint information are substantially matched, the subsequent to-be-measured batches of products meet the requirement. On the condition that the fingerprint information of one or more types of materials are not matched with the filed fingerprint information, the above products substantially do not conform to the filed products. Through the further analysis on the fingerprint information of materials that are not matched with the filed fingerprint information, the types of monomers and additives can be determined. Meanwhile, the types of monomers and additives are compared with the types of available monomers and additives specified in the regulations. On the condition that the types of monomers and additives do not conform to the types of available monomers and additives specified in the regulations at the same time, the source of materials that compromises the safety can be addressed.

Description

technical field [0001] The invention belongs to a packaging material safety analysis and traceability method. It specifically involves the traceability method of food packaging material safety fingerprint method. Background technique [0002] Plastic composite flexible packaging refers to the packaging that can change the shape of the container after filling or taking out the contents. It is currently widely used in food, cosmetics, medicine, electronic appliances and other industries, and has become the second largest packaging industry after paper packaging. With the progress of social civilization and the improvement of living standards, plastic composite flexible packaging is more and more used in food packaging, which provides a strong guarantee for the quality, freshness and transportation of food. However, as personal clothing for food, the impact of migration of risky substances in packaging materials on food hygiene and safety has been widely concerned. To this en...

Problems solved by technology

However, the implementation of such regulations and standards usually only relies on the supplier questionnaire issued by downstream users to upstream suppliers or the product conformity statement issued by upstream suppliers to downstream users, lacking strong technical means as support, resulting in regulations, especially technical The implementation of regulations or regulations with high technical content stays on paper

[0003] At present, health and safety problems in the food contact packaging material industry chain are usually discovered after the finished product is used for packaging food. The traditional traceability method characterized by labels and barcodes is mainly to detect the corresponding batch of raw materials after the accident. Due to the diversity of raw materials and most of them are mixtures of several chemical substances or even polymer substances, it is difficult to analyze accurately, resulting in unclear location of the cause of the accident, and the problem was discovered after the finished product was made, which also caused serious material waste.
