There were no significant differences in color, tenderness, or juiciness. A previous study showed that high fat content had no effect on the hardness of frankfurters The addition of PSFM and pig skin had no significant effect on the flavor and warm-off flavor, which was the same as that of the control. The overall acceptability score of the sausages with PSFM ranged from 8.11 to 8.56. The incorporation of PSFM as a fat substitute did not deteriorate the sensory properties of the low-fat sausages, and these properties were the same as those of the control.
