摘要: 为探讨微酸性电解水冰对罗非鱼片保鲜效果的影响,对比分析微酸性电解水冰与自来水冰贮藏罗非鱼片的感官评分、pH值、总挥发性盐基氮含量、K值和菌落总数的变化。结果表明:与自来水冰处理组相比,微酸性电解水冰能抑制1 ℃贮藏过程中罗非鱼片的总挥发性盐基氮含量、K值、菌落总数的增加;微酸性电解水冰处理的罗非鱼片感官评分更高;综合来看,微酸性电解水冰处理可以将罗非鱼片的货架期延长3~4 d,能更有效地保持罗非鱼片的品质。本研究可为微酸性电解水冰应用于水产品流通环节的保鲜提供理论参考。

Abstract: The objective of this study was to investigate the effectiveness of slightly acidic electrolyzed water ice (SAEWI) in preserving the quality of tilapia fillets. Tilapia fillets were stored in SAEWI or tap water ice (TWI) and evaluated for changes in total volatile basic nitrogen (TVB-N) content, K value, pH, total colony number and sensory quality. The results showed that compared to TWI, SAEWI could inhibit the increase of total bacterial count, TVB-N content and K value during storage at 1 ℃, and imparted higher sensory scores to tilapia fillets. Overall, the shelf life of tilapia fillets treated with SAEWI could be prolonged by 3 to 4 days, and the quality of tilapia fillets was maintained more effectively. This study provides a theoretical basis for the application of SAEWI to preserve aquatic products during circulation.
