shows the consumer acceptance of yogurts. The fortifi- cation of yogurt with the HS was associated with a statistically significant effect (p < 0.001) on all of the parameters analysed except for odour. The control sample was acceptable. For all of the parameters analysed, the control scored the central value of the scale (3 ¼ neitherlikenordislike). Consumerspreferred3% HSto6% HS. This preference can possibly be explained because HS was associated with increased liquidity of the samples (see syneresis value Table 3).
For the 3% HS samples, the San Giovanni and TGTcultivar scores always achieved the central scale value for the 6% HS samples. The San Giovanni cultivar had the highest score for all of the parameters, but only the odour achieved the central scale value.
In general, the observed low acceptance of the fortified yogurts was not surprising because similar results have been previously observed in other studies in which different types of fibre were used. Tseng and Zhao (2013) observed that the use of fibre was associated with a lower value for flavour, texture and consistency. Hashim, Khalil, and Afifi (2009) reported that the addition of fibre was associated with lower ratings for firmness, smoothness and
flavour. Sendra et al. (2008) observed that the addition of fibre was associated with reduced creaminess and decreased overall acceptability.
