Food Contact

Bisphenol A (BPA)-based epoxy resins have wide applications as food-contact materials such as metal can coatings. However, negative consumer perceptions toward BPA have driven the food packaging industry to develop other alternatives. In this study, four different metal cans and their lids manufactured with different BPA-replacement food-contact coatings are subjected to migration testing in order to identify migratory chemical species from the coatings. Migration tests are conducted using food simulants and conditions of use corresponding to the intended applications and regulatory guidance from the U.S. Food and Drug Administration. Extracts are analyzed by gas chromatography mass spectrometry (GC-MS) and high resolution GC-MS. The migratory compounds identified include short chain cyclic polyester migrants from polyester-based coatings and bisphenol-type migrants including tetramethyl bisphenol F (TMBPF), tetramethyl bisphenol F diglycidyl ether (TMBPF DGE), bisphenol F (BPF), bisphenol C (BPC), and other related monomers or oligomers. The concentration of the migrants is estimated using an internal standard, and validated trimethylsilyl (TMS) derivatization GC-MS methods are developed to specifically quantify TMBPF, BPF, BPC, and BPA in the coatings. The results will aid the safety evaluation of new food-contact material coating technology based on TMBPF chemistry and will provide an important reference for the industry in identifying and quantifying non-BPA coating-borne migrants.

Perfluoroalkyl And Polyfluoroalkyl Substances

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are synthetic chemical compounds widely used in different industry fields including food contact materials (FCM), providing resistance to fat and humidity, and non-stick properties. PFAS enter into the food chain directly from the intake of contaminated food or indirectly from the migration of the FCM into the food. This exposure published in different research highlights a public health concern. Therefore, it is necessary to perform analysis of the content of different FCM and evaluate the migration from the FCM under normal conditions of use and storage. This bibliographical review proves that different perfluoroalkyl and polyfluoroalkyl compounds are detected in fast food packaging, microwave popcorn bags, and frying pans, among others. Furthermore, it shows the conditions or factors that favor the migration of the PFAS from the FCM into the food.

Political Security

According to the Report presented in the ONU Program for Development there are eight dimensions of international security (collective security) and national security: economic-social security, food security, environmental security, community security, personal security, political security and individual security, to which demographic security and military security could be added. Although there have been concerns about the nutrition status of the population since ancient times, it was only in the middle of the last century that the scientific and institutional bases of contemporary food and nutrition policies were laid. Food and nutrition policies are represented by a series of objectives, priorities, norms and decisions adopted by the invested factors and institutions with the competences necessary to ensure to the entire population the economic and social conditions for a good state of individual and public health. Packaging has become one of the most important functions of a product, of a commodity on the market. The packaging is part of the Food Contact Materials (FCMs) group, which should not affect the health of consumers or alter the quality of the products. The breadth and complexity of the socio-economic context in the food contact sector requires finding additional ways to adapt. In this context, the textile sector, respectively the field of technical textiles, through the potential of functionalities, can make a special contribution to achieving a level of coherence between the field of functionalized materials intended for food packaging – environment – consumer health – free movement of products – efficient functioning of the internal market.
