Properties and Structure of Blend Films With Chitosan and Gelatin From Dosidicus gigas Skin
摘要
Abstract
In order to study the modified effect of chitosan on the films prepared from Dosidicus gigas skin gelatin,the effect of chitosan addition on the mechanical properties,water vapor permeability,light transmission,thermostability and texture of complex films with different ratio of gelatin and chitosan was investigated.The results indicated that the chitosan can improve the properties of edible gelatin films.When the gelatin solution and chitosan solution mixed with a ratio of 60:40(v/v),the elongation at break of blend gelatin-chitosan films decreased compared with the single gelatin film,but the tensile strength,light transmission and water vapor barrier ability increased by 625％,11％ and 48％,respectively.The results of fourier transform infrared spectroscopy(FTIR) and differential scanning calorimetry (DSC) showed that the chitosan can interact with squid skin gelatin,form the dense homogeneous system structure and improve the thermal denaturation temperature of the composite film.Chitosan is an ideal modified material for gelatin films by a clear interaction between chitosan and gelatin from Dosidicus gigas.The results can provide theory basis for using films prepared from Dosidicus gigas skin gelatin as food wrapper.关键词
