To further improve the physicochemical properties of chitosan coating and prolong the fruit storage life,organic/inorganic hybrid materials are promising systems due to their synergistic properties. These are easily produced through sol–gel chemistry which is a very versatile method allowing incorporation of inorganic components like metal alkoxide namely, Si, Ti, Zr or even bioactive materials to modify final chemical and physical properties of materials (Yeh et al., 2007; Lai et al., 2006; Dhanasingh et al.,2011).
