Abstract： In order to develop a healthy fat substitute with high protein and low fat of proteinpolysaccharide composite matrix emulsion gel，the soy protein isolate-casia gum composite matrix emulsion gel after heat treatment is studied. Different concentrations （0% ， 0.85% ， 1.15% ， 1.45% ， 1.75% ， 2% ）of cassia gum （GC），soybean protein isolate （SPI） and rapeseed oil are used to prepare emulsion gel. The effcts of different concentrations of GCon the texture，rheological properties，stability and microstructure of the composite matrix emulsion gel are studied. The results show that with the increase of CG concentration， ESI，EAI， texture and WHC of the emulsion gel all increase. Through rheological analysis，it is found that the addition of CG makes the gel network structure stable and dificult to be destroyed，and its viscosity decreases with the increase of shear rate. Microstructure observation shows that the droplets of emulsion gel gradually become smallr，and the dense network structure prevents the aggregation of oil droplets. DSC analysis shows that when CG addition amount is 2% ，the denaturation temperature of emulsion gel changes from 69.25∘C to 80.66∘C ，thus improving the thermal stability. The application of emulsion gel as a fat substitute in minced meat sausages significantly improves their emulsion stability and sensory score，and the overall acceptability of T4 is the highest of （8.33±0.21） points.
