Study on prolonging shelf-life of packaged hunter-sausage with combined-preservative

In this paper,sodiumlactate,sodium diacetate,Nisin,pH regulator were used in packaged hunter-sausage as combined-preservative.The Results of orthogonal experiment revealed that the growth of microorganisms could be significantly inhibited when the optimal composition of preservative contained 2% of sodiumlactate,0.1% of sodium diacetate,0.03% of nisin and 0.1% of pH regulator.The shelf-life of the hunter-sausage could be 60 days at normal temperature.Putting the result into practice,the shelf-life of hunter-sausage could be prolonged efficiently.
