Preparation and Properties of Oxidized Agar

XIA Kai;ZHAO Jingkun;AN Xingjie;LIU Xin;School of Chemistry Science and Engineering of Qingdao University;  
The Oxidized Agar was prepared by ferrous sulfate as catalyst and reaction of agar with hydrogen peroxide and the properties of Oxidized Agar were tested.The results showed that the gelling temperature,the gel melting temperature,the gel strength,optical rotation,apparent viscosity of Oxidized Agar decreased while the water holding capacity increased.The gel skeleton microstructures of Oxidized Agar and Raw Agar tended to be a porous network structure.The hardness,the fracturability,the springiness,the chewiness of Oxidized Agar gels decreased except that the cohesiveness increased with the increase of the oxidized degree.
