With milk as the main raw material,different coagulants and protease were applied in the study of rapid solidification technique in producing dairy products and the determination of its parameters.The specific process parameters are: milk powder content of 70.20%,composite solidification synergist 5.440%,0.088% papain,0.88% gelatin,sugar,23.40%.Under the above conditions,milk solidifies in a moderate rate,tastes delicate and pure,and there was little whey precipitates,which are in consistent with the objectives of the experiment.
