*2.3.4.1 Polysaccharide-protein edible coatings*

The protein-polysaccharide-based composite film has good mechanical and watervapour permeability property because interaction between protein-polysaccharide results in mono-phase film [18]. This composite film is proposed to be used as edible film for packaging in food industry [96]. Combination of carboxy methyl cellulose with soy protein improves the structure and properties of edible film [97]. By decreasing gas transfer rate in fruits, shelf life is increased; this is possible by using edible film made from collagen-galactomannan mixture [98].
