Peanut protein powder contains very high nutritional value. The powder was added into the sausage, which can not only improve the value quality of the products but also increase the usage of peanut protein powder. The optimal formula to produce sausage product was obtained by the single factor and orthogonal test with peanut protein powder, ratio of thin to fat, starch content as factors. The result showed that mass fraction of peanut protein powder was 5%, the ratio of thin to fat 83∶17 and the mass fraction of starch 8%. The peanut protein powder sausage products developed have the special flavor of peanuts, clear fleshcolor and elasticity with compact slice without pores.
