on muscle protein emulsifying properties andStainless steel reaction kettleIn the past, the research was mainly based on the addition of vegetable oil as a dispersed phase model, and the theory of oil-in-water emulsification was put forward.(protein membrane encapsulation) and physical mosaic immobilization theory (protein matrix embedding immobilization). However, in the meat industry, animal muscle and fat are also used as raw materials for processing, and vegetable oils are hardly used. So far, muscle protein and fat shearStainless steel reaction kettleThe research on emulsifying properties has not been able to break through, and minced meat products often have problems such as water and oil.


     high shearStainless steel reaction kettleEffect of shear time on particle size distribution and emulsifying characteristics in meat emulsion ResearchThe effects of different shearing time (1 min, 3 min, 5 min and 7 min) on the size and size distribution of fat particles in meat emulsion, emulsion stability and gel hardness were investigated at 3000 rpm. The results showed that after fat shearing for 5 min and 7 min, the fat particles in the meat emulsion were smaller, the particle size distribution range was narrow, the uniformity was better, the emulsion stability was good, and the gel strength was high, but the difference between the two treatment groups was not significant (P0.05). Therefore, in this experiment, backfat was selected to be sheared at a shear speed of 3000 rpm for 5 min to make meat emulsion and gel, which can meet the research needs of later chapters.
