Four kinds of edible composite films based on chitosan combined with additional substances (konjac glucomannan, cassava starch, maltodextrin and gelatin) the addition lysozyme were prepared used as packaging materials for Mongolian cheese. The evaluated using scanning electron microscopy Fourier transform infrared spectroscopy. physicochemical properties all films, including thickness, viscosit...

the effects of nano titanium dioxide incorporation were investigated on the water vapor permeability, oxygen permeability, and antimicrobial properties of bovine gelatin films. the nano tio2 (tio2- n) was homogenized by sonication and incorporated into bovine gelatin solutions at different concentrations (e.g. 1, 2, 3, and 5% w/w of dried gelatin). the permeability of the films to water vapor a...
