This indicates that the level of hazelnut concentration influenced
the fat bloom formation.
The significant difference between the V2Hu-fresh and V1Befresh
confirms that the higher liking of V2Hu (Table 3) can be
due to the uniformity of the appearance of the filled chocolates
that are produced industrially. The evaluation by the consumers
of the texture and taste of the four samples gives similar results.
For the fresh samples, the texture and the taste of the V2Hu samples
were significantly better than for the V1Be samples. This again
confirms the overall higher liking of the V2Hu samples (Table 3).
The difference can be due to the higher level of hazelnut oil concentration
which makes the filling softer and perhaps increases
the intensity of the hazelnut flavour of the filling. However, that
possibility was not analyzed during this study.
Relationship matrix. The central part of the HOQ in this study was
established through extensive literature review and experience
with the sensory characteristics and production procedure. The
attributes that belong specifically to one of the four constructs
receives a value of 9. For example gloss, intensity of color, blooming,
cracking, air bubbles and leakage are strongly related to
