Method Pre-rigor pork, ageing pork and frozen pork were pre-blended with 5 levels of phosphate and made emulsion-type sausage. Yield, hardness and total expressible fluid were measured with texture profile analysis machine and pressiometer when emulsion-type sausage was produced. Hardness and purge loss were measured during 30 d storage.ResultAs emusion-type sausage made by pre-rigor meat, higher yield and relatively stable hardness could be found. Increase of phosphate level caused an alleviatable effects in increase of hardness when emulsion-type sausage made by pre-rigor meat, but an worse effects in increase of hardness when emulsion-type sausage made by ageing meat or frozen meat. Phosphate affects the distribution of purge loss of emulsion-type sausage. Significant decrease of purge loss could not be obtained by increasing phosphate level during storage.ConclusionPre-rigor meat improved water-holding capacity and texture of emulsion-type sausage. Problem of water-holding capacity and texture of emulsion-type sausage during storage could not be resolved by single use of phosphate at relatively higher level (3%) of NaC
