A triple test was carried out presenting to the panelists B0 and B20 samples. These samples were chosen, as B20 was the sample with higher fat replacement that showed similar structural and textural behavior than B0. Fifty total triangle test responses would require 23 correct responses to be significant at the 95 % confidence level (Roessler et al. 1978). Using the composite data, the proportions of correct responses for the biscuit samples were 33:50. Therefore, the results indicate that panelists were able to differentiate between B0 samples and the B20 samples. However, when panelists were asked about the differences between samples, they described only slight differences: B0 was slightly less hard and less sweet than B20. The higher sweetness of B20 is due to the sweetness of the inulin added to replace the fat (inulin sweetness is 10 % if compared to sucrose 100 %), and although panelists found slight differences in hardness, no significant differences in penetration force were found between these two samples in instrumental hardness, as it is explained before
