The addition of PFA (at 2.5 or 5%) did not affect (p N 0.05) the juiciness or chewiness of pork burgers.
These descriptors did not lead to differences in sensory scores even though they were detected by instrumental texture assessment (Table 3).
This could be explained by the higher swelling capacity of PFA.
For granularity descriptor no statistical differences (p N 0.05) were found between the control samples and the samples added with different concentrations of PFA.
For overall acceptability, the samples added with 2.5% of PFA showed the highest scores.
The panelist gave similar values to burger control and burgers added with 5% of PFA (p N 0.05) for this descriptor.
