Features of the use of food simulators used when testing packaging for the study of food aluminum foil

Introduction. Aluminum foil is one of the most widely used food packaging, since it has a set of high consumer characteristics. At the same time, the food foil can serve as a source of aluminum entering the human body, but there is no specific method of testing foil. In this regard, the study of the spectrum and features of the application of food simulators is relevant to improve various stages of food aluminum foil testing. 

The purpose of the study is to investigate the features of the use of food simulators and testing stages used as a whole for any food packaging in the study of aluminum foil. 

Materials and methods. With the application of the elements of the PRISMA systematic reporting reports on systematic reviews, the analysis of scientific and technical literature on the features of the use of food simulators when testing the food aluminum foil were performed. Measurement of aluminum content in food simulators after contact with aluminum foil was carried out by spectrometry methods. 

Results. When testing the food aluminum foil, it is impractical to the use of the entire list of food simulators recommended by TR TS 005/2011. It was established to be advisable to improve the current instructive methodological base, in particular the pre-analytic stage of sample preparation. A method of sample preparation and spectral measurement methods was carried out by a comparative experimental measurement of real samples of food simulators after contact with the foil. 

Limitations. The limitation of the study was the use in the experiment exclusively of samples of aluminum foil with a thickness of 0.009 mm from aluminum alloy 8011 and aluminum foil with a thickness of 0.02 mm from aluminum alloy 1200. account the features of the use of aluminum foil into everyday life, therefore, the methodological approaches to the stages of its testing need to be improved. The developed method of sample preparation allows applying unified requirements in the process of testing food aluminum foil to safely use it in everyday life.

Conclusion. The list of model environments for the study of any food packaging does not take into account the specifics of the use of aluminum foil in everyday life, therefore, methodological approaches to the stages of its testing need to be improved. The developed method for sample preparation allows applying unified requirements in the process of testing food-grade aluminum foil for the purpose of its safe use in everyday life.

Compliance with ethical standards. Research does not require the submission of a biomedical ethics committee opinion or other documents.
