Analysis of Brazilian consumer preference of filled chocolate

Chocolate is the most popular product made from cocoa. It is mainly consumed with fillings, such as fondant, hydrogenated fat or fruits. This work aimed at assessing the sensory acceptability of chocolate filled with strawberry, orange or passion fruit pulps, mixed in fondant, in a hydrogenated fat base and as truffles. Ninety four consumers participated in the test using a 10 cm hedonic scale to rate the overall liking of the samples. Two-way analysis of variance and the Internal Preference Mapping technique were used to analyze the data. Results showed a good overall liking for almost all samples, especially for strawberry and passion fruit truffles, which obtained 8.4 and 8.8 global means, respectively (p < 0.05), in liking ratings, followed by the hydrogenated fat and fondant fillings. The Internal Preference Map presented two dimensions explaining 72.5% of the variation found. Regarding the flavors, strawberry - traditional in chocolate and confectionary in Brazil - and passion fruit obtained better acceptance, unlike the orange fillings, which showed significantly lower ratings (p < 0.05). The orange fondant filling obtained a global mean of 6.5.
