Abstract:The quality and texture changes of Lateolabrax japonicus meat during partially frozen storage were studied.Tissue structures,texture profile analysis and changes of rheological properties(elastic modulus E0, stressrelaxation time τ1, viscosity η1, rupture strength),combined with the total number of bacteria,K value,TVB-N,pH value and sensory scores were determined.The results suggested that the total number of bacteria,K value and TVB-N increased with the extension of storage time,while pH value decreased and then increased.The increasing speed increased with temperature.As the storage time extended,the pores of the myofibril increased,the tissue structure deteriorated,elastic modulus E0 increased, and rupture strength,hardness,springiness,cohesiveness and chewiness decreased,while viscosity η1 and stressrelaxation time τ1 have no significant changes.Compared with that of the refrigerated samples,the shelflife of partially frozen storage samples could be extended for 20 days.It showed partial freezing could effectively inhibit the activity of enzymes in the meat of Lateolabrax japonicus and the effect of micro-organisms, so that it could alleviate the decomposition of protein.As a result,partial freezing storage is an effective method to extend the storage time of Lateolabrax japonicus.
