Abstract

Building upon previous research that focused on the preparation of nano-cinnamaldehyde (Nano-cin) and its application in fruits preservation, this study was designed to explore a gentle yet effective preservation approach for post-mortem Baijiao seabass.By comparing with water and ClO2 treatment, the impact of Nano-cin on the bacterial diversity and shelf-life of Baijiao seabass was evaluated.The results demonstrated that Nano-cin treatment effectively decreased the initial colony count of the fish and effectively inhibited bacterial growth during storage, extending the shelf-life to 8 days (in contrast to only 6 days in CK).High-throughput sequencing analysis revealed that Nano-cin specifically suppressed the growth of Aeromonas and Psychrobacter during the early storage period, and also hindered the proliferation of Shewanella putrefaciens.Notably, the inhibitory effect of Nano-cin on Shewanella putrefaciens was superior to that of ClO2, enabling it to effectively control specific spoilage bacteria in seafood.Furthermore, Nano-cin effectively delayed lipid oxidation and protein degradation.At 8 days of storage, the total volatile base nitroger (TVB-N) and thiobarbituric acid reactive substances (TBARS) values were reduced by 15.50% and 12.81%, respectively, compared with those in the CK.Additionally, Nano-cin preserved the natural color of the fish, avoiding the whitening side effect caused by the strong oxidizing properties of ClO2.In conclusion, as a novel bio-antimicrobial agent, Nano-cin shows great potential for the post-mortem preservation of aquatic products.
