Preservation Effect of a New Nano Antibacterial Film on Hairtail
In order to explore the green and effective fresh-keeping packaging materials for Marine fish,a new type of nano-antibacterial film was prepared,and the fresh-keeping control experiment was carried out with hairtail under cold storage(0℃～4℃).The experiment compared the changes of TVB-N value,PH value,microbial detection and sensory score of three different formulations of nano-antibacterial film in 5-week storage time,and tested the preservation effect of the film.Among them,the TVB-N data of nano-antibacterial film packaging group is the most stable,the best quality and preservation,and has the best antibacterial and preservation effect.The results showed that the antibacterial film effectively delayed the increase of PH of fish,slowed down the loss of fish weight,and better maintained the flavor of fish.
