The model fitted adequately the data at P≤0.05. A comparison between
observed measurements and predicted values for acceptance
had an average relative error of 4%. The model was used to generate
the surface plot (fitted response) for the acceptability of the reduced
fat mincedmeat (Fig. 5). The results showed that combinations of protein
(2.5%,w/w) and inulin (2%,w/w), at the left side of the figure, had a
higher average acceptability. The acceptability declined towards the
right side of the experimental area,where proteins at 3% (w/w)without
inulin were tested.
