Shelf-life determination of tiger-toothed Croaker (Otolithes ruber) during flake ice storage

Authors

Abstract

Quality of tiger-toothed croaker stored in flake ice was studied for 19 days by sensory,
chemical (total volatile basic nitrogen (TVB-N)), (thiobarbituric values (TBA)), pH and
microbial (total viable count, TVC) methods. Sensory scheme was modified according to the
panelists perception and a specific schema was created for this fish. Sensory analyses showed
that: "gills color and odor", "convexity of eyes", "peritoneum" and "elasticity of flesh" are the
best sensory parameters. Results of sensory and microbial analyses had high correlation. Total
viable count of flesh was 2.86 log cfu g-1 at first day and reached the limiting level of TVC
(106) after 15 days of storage (P
