Sensory profiling and mapping of gluten-free cookies made from blends Cardaba banana flour and starch

摘要

Sensory profiling of gluten-free (GF) cookies made from cardaba banana flour and starch blends were evaluated using trained panelists/assessors. The sensory attributes used to separate the cookie samples were appearance, aroma, taste, and texture/crispiness of the cookies. Sensory mapping (internal and external preference mapping) was evaluated using multidimensional scaling of data obtained using a 9-point hedonic scale. Analysis of the panelists revealed the rating of the cookie samples was not affected by the aroma attribute. The result of internal preference mapping revealed that the first three principal components extracted accounted for 71% of the total variation. External preference mapping shows that the potential for predicting assessors overall acceptability of the cardaba banana cookies using five sensory descriptors which drove the preference of some of the five assessors’ clusters. The formulation of GF cookies is feasible and the result obtained may facilitate the marketability of GF food that is comparable to conventional cookies in sensorial attributes.
