Abstract

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.

Key words: slightly acidic electrolyzed water ice, tilapia fillets, preservation, total volatile basic nitrogen content, K value
