Abstract The objective of this study was to evaluate the effects of injection triplephosphate at post
mortem on quality of pork. The pork was randomly divided into four groups and injected solution with
different concentration of sodium tripolyphosphate (0, 0.2%,0.3%,0.4%) . After refrigerated at 4℃ for
72h,the tenderness, pH value, cooking yield and sensory evaluation were measured. The result indicates
that the control treatment has lower cooking yield, worse flavor and is tougher than the other treatments.
The cooking yield, flavor and tenderness improved when the concentration of the phosphate increased,
but no differences in color was observed among all the groups. The results suggest that injection of the
solution containing phosphate into muscle can improve the quality of pork.
