Post-mortem Biochemical, Microbiological and Sensory Quality Changes in the Grass Carp (Ctenopharyngodon idella) during Ice Storage
In this study, biochemical, bacteriological, and sensory changes of ice stored (0 ˚C) grass carp (Ctenopharyngodon idella) were investigated. Whole, ungutted fish were stored in insulated ice boxes maintaining a 1:2 fish ice ratio and analyzed periodically at every 3-day interval. On a fresh matter basis, moisture, crude protein, crude lipid, and ash content of grass carp during ice storage varied significantly (P < 0.05). The initial pH value of 6.76 increased to 7.05 on the 12th day of ice storage. Throughout the storage period, total volatile basic nitrogen and thiobarbituric acid reactive substances values were increased. K-value also increased from 2.32% to 68.74% within 12 days. Aerobic plate count and total psychrotrophic count suggested that the fish was safe for human consumption until the 9th day of storage; a similar acceptance period was also revealed by the result of sensory evaluation. From the evidence, it can be concluded that the shelf life of ice stored C. idella was 9 days in an insulated ice box with the above-mentioned fish ice ratio.
