“นอกเหนือการสับ” leads to a thin protein film having a low mechanical strength unable to stop fat droplets’ migration to the product surface, where they from small pocket of fat called “fat caps”. Temperature increases during chopping cause the melting of part of the fat and a decrease in the surface tension of the fat particles. For cold-emulsions, in conventional cutters, the knives can reach local peak temperature of up to 75°C. This causes denaturation of the proteins, which then from unwanted small lumps in the sausage meat and partly lose their ability to bind water.
