Carrageenan polysaccharides for food packaging

M.D. Sanchez-García,     Novel Materials and Nanotechnology Group, IATA-CSIC, Spain

Abstract:

This chapter discusses the applications of carrageenan materials for food packaging and the effect of the addition of nanoreinforcement vectors in the barrier properties to gases and vapours and to impart additional functionalities to biopackaging plastics. The chapter first discusses the carrageenan structure and properties and then describes the applications in food packaging and their barrier properties. Finally, a case study of nanocomposites of carrageenan based on nanoclays or cellulose nanowhiskers showing enhanced gas, vapour and UV barrier of interest in food biopackaging applications is ...
