Abstract
The melanosis development and quality deterioration of Litopenaeus vannamei treated with starvation prior to storage were monitored during cold storage at 4â¯Â°C for 8 days. Compared with the control group, the shrimps subjected to starving showed lower melanosis score and the significant retarding effect on melanosis development was observed in the shrimps with starvation for 2 days (Pâ¯<â¯0.05). Furthermore, the changes in quality-related biochemical attributes such as pH, total volatile base (TVB), protease and polyphenol oxidase (PPO) activities revealed that starvation for 2 days could significantly inhibit the microbial proliferation and the activities of endogenous protease and PPO (Pâ¯<â¯0.05), with highest scores for brightness and overall acceptability than others at the end of storage. Therefore, shrimps starved for 2 days before storage could be a promising method to inhibt melanosis and deterioration during refrigerated storage.
