The fish samples were considered to be acceptable for human
consumption until the sensory score reached 4 (Truelstrup
Hansen, Gill, & Huss, 1995). The results of the sensory evaluation
of samples are given in Fig. 6. Sensory scores showed a significant
decline in both lot I and lot II samples with increasing storage
period and, also, the lot I sample received a higher score
than did the lot II sample. It is well known that fish spoilage
gives rise to the subsequent development of strongly fishy, rancid
and putrid odours, and fish are then clearly rejected for consumption
by any taste panel. Thus, lot II was acceptable up to 25
days while lot I was in good and acceptable condition during the
entire 30 days of storage. This may be attributed to chitosan’s
functional properties, e.g. antioxidant, antimicrobial and oxygen
barrier, and this conclusion is supported by the results of chemical
quality analyses
