Protective packaging for light-sensitive foods

Abstract

Consumer expectations and interests in nutritional aspects and visual appearance,when purchasing food, are important factors that should be taken into account toimprove the food industry (Gadioli et al., 2013). Currently, food packaging is strongly linked to material transparency, which must not hide the product but enable its visibility through the packaging (Eldesouky et al., 2015). Nevertheless, many food natural components as well as those added during their preparation are susceptible to light, causing the occurrence of photo-degradative and oxidative reactions (Duncan and Chang, 2012). Foods are exposed to several sources of light during their entire chain of production and commercialization.
