2.5. Sensory evaluation
The overall acceptability of silver carp fillets was determined
using a five point scale considering texture, color and odour of the
samples. Panellists scored for sensory characteristics, such as color
discoloration (5, no discoloration; 1, extreme discoloration); odour
(5, extremely desirable; 1, extremely unacceptable/off-odours) and
texture (5, firm; 1, very soft). The averages of these scores were
defined as overall acceptability (5, extremely desirable; 1,
extremely unacceptable). Shelf life criteria assumed that rejection
would occur when the sensory attributes declined below 4.0 (Ojagh
et al., 2010).
