Effects of Rigor‐State, Levels of Salt and Sodium Tripolyphosphate on Physical, Chemical and Sensory Properties of Frankfurter‐Type Sausages

Abstract

ABSTRACT Preblends of prerigor or postrigor pork with 2 or 4% salt were used to make sausages with finished product salt contents of 2.5 or 1.5% and with or without sodium tripolyphosphate. pH values increased (P > 0.001) when sausages were made with preblends of 4% salt or when phosphate was used. Reducing salt contents from 2.5 to 1.5% did not (P < 0.05) affect physical, chemical or sensory properties except for saltiness and Instron force of rupture values. Firmness of sausages increased (P < 0.05) when sodium tripolyphosphate or preblends with 4% salt were used. Data suggest that salt levels could be reduced 50% without detrimentally affecting physical, chemical or sensory properties of these frankfurter‐type sausages.
