In order to make better use of pork by-products, being consumed unsanitarily at present, sausage was manufactured formulating of four different levels(20, 40, 60 and 80%)of pork by-products mixture(Liver: Lung: Stomach=2 : 1 : 1). And the effect of phosphate-complex levels ( 0 , 0.3, 0.6 and 0.9% ) on the quality of the sausage formulated with 40% pork by-products mixture was investigated during the storage period of 36 days at 5 ℃. The results obtained were summarized as follows; 1. The appropriate level of pork by-products mixture for the sausage was evaluated at 40%. 2. The flavor score, pH, water-holding capacity, emulsion stability and the redness were significantly increased while the V.B.N., T.B.A. value and yellowness of sausage were significantly decreased by the addition of phosphate-complex. However, the residual nitrite was increased significantly by the addition of phosphate-complex.
