- Chapter 44 - Prickly pearPublication . Albuquerque, T.G.; Pereira, P.; Silva, M.A.; Vicente, F.; Ramalho, R.; Costa, H.S.Nowadays, consumers are increasingly interested in foods that are linked with health benefits, in addition to their nutritional composition. Prickly pear (Opuntia ficus-indica (L.) Mill.) is native to Mexico, but nowadays it is widely spread among other regions of the world, such as Africa, Australia, and the Mediterranean basin, due to its pleasant organoleptic features. Prickly pear belongs to the Cactaceae family, which includes over 1500 species of cacti. Moreover, it is gaining popularity among consumers due to the presence of bioactive compounds, namely polyphenols, vitamins, polyunsaturated fatty acids, carotenoids, and sterols that are associated with relevant functional and biological activities, such as antiinflammatory, antioxidant, and hypoglycemic properties, among others. In addition, this plant can also be used as a fence in gardens and fields and is useful in helping to combat desertification as it grows in arid and semiarid regions. Nowadays, it is widely used to manufacture food products, such as juices and jams, but it is also consumed as a fruit. Prickly pear is a promising source of phytochemicals, which can be useful for food, or in the cosmetics or pharmaceutical industries to develop new products with health-promoting properties, namely, functional foods, natural additives, or dietary supplements.
- Food Additives and Human Health - Indirect AdditivesPublication . Andrade, Mariana; Ribeiro-Santos, Regiane; Nabavi, Seyed; Sanches-Silva, AnaIndirect food additives are the additives that are not intended to be added directly to foods but are added to food contact articles namely, food packaging. In this chapter, the main indirect additives are reviewed, as well as, the legal aspects and regulatory control applied to these kinds of substances in the USA and the European Union. The migration of some of these compounds to foods is undesired and, in some cases, may represent a threat to human health. This chapter also highlights some specific groups of indirect additives including monomers, plasticizers, antioxidants and antimicrobials, catalysts, initiators, curing and cross-linking agents, stabilizers, and solvents. Future trends in the use of indirect additives are also discussed in this chapter. Innovative technologies in the food packaging industry are emerging every day, so the regulations and the regulatory agencies must be updated.
