Sensory analysis
Sensory quality changes and overall acceptability of fish
burger are given in Table 4 and 5. The appearance, texture,
odor and flavor of the fish burger started decreasing at a
significant level of 1 % level. According to the results of
overall sensory evaluation, fish burgers were acceptable up
to 15 days. Yerlikaya et al. (2005) reported the limit of
acceptability for anchovy patties in refrigerated storage for
6 days. Turhan et al. (2001) determined the shelf life of
refrigerated raw anchovy (E. encrasicholus) patties for 6 days
at 4 °C. Taskaya et al. (2003) reported that fish burger made
from rainbow trout was not microbiologically good and
should be consumed before 9 days of the storage. The above
mentioned studies showed the very similar results with the
present study. A negative correlation was observed between
storage time and sensory score (−0.991) and the correspond-
ing regression equation is y =9.25 – 0.35 × (Fig. 1 and
Table 6).
