The coatings of metal cans may release complex mixtures of migrants into the contained foods, including non-intentionally added substances (NIAS), such as reaction products. All migrating substances should be studied to demonstrate their safety. In this work, the characterisation of two epoxy and organosol coatings was performed using several techn...

Fruits and vegetables are high preference products of human consumption due to their several health benefits. However, their short shelf life requires innovative strategies of preservation such as active packaging systems to maintain the quality and enhance the organoleptic and nutritional properties of the food. This chapter provides insights on r...

Polymeric coating formulations may contain different components such as cross-linking agents, resins, lubricants, and solvents, among others. If the reaction process or curing conditions are not applied in a proper way, these components may remain unreacted in the polymeric network and could be released and migrate into foods. In this study, severa...

Human dietary exposure to chemicals is a priority issue for public health authorities and constitutes a key step in risk evaluations. The safety of food contact materials, such as food packaging, is a main topic in the field of food safety in the EU and requires the evaluation of the chemical substances that can migrate from the material into the f...

Polymeric coatings are used as a protective layer to preserve food or beverage quality and protect it from corrosion and avoid a metallic taste. These types of materials can contain some chemicals that are susceptible to migrate to food and constitute a risk for consumers’ health. This study is focused on the identification of volatile and semi-vol...

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 th...

Major type of internal can coating used for food and beverages is made from epoxy resins, which contain among their components bisphenol A (BPA) or bisphenol A diglycidyl ether (BADGE). These components can be released and contaminate the food or beverage. There is no specific European legislation for coatings, but there is legislation on specific...

The main aim of this review was to assess the incidence of Pb, Hg and Cd in seafood from African countries on the Indian and the Red Sea coasts and the level of their monitoring and control, where the direct consumption of seafood without quality control are frequently due to the poverty in many African countries. Some seafood from African Indian a...

Xanthohumol (XN) is the main prenylated chalcone present in hops (Humulus lupulus) with high biological activity, and it is of great importance for human health because of its antioxidant, anti-inflammatory, immunosuppressive and chemopreventive properties. This polyphenol can be included in the diet through foods in which hops are used, such as be...

Food packaging is a key part within the food safety. The components of these food contact materials should be studied with great caution because they can migrate to the food depending on several factors. Many of these food containers are made of materials such as polycarbonates or paper and cardboard. These polymeric materials can decompose at high...
