The Impact of Different Molecular Weight Chitosan Dip-coating on the Quality of

In this research, the impacts of chitosan with different molecular weights (30, 150, 300 kDa) on the quality of Monopterus albus during refrigeration storage were investigated in terms of total colony count (TCC), ph, TVB-N , water loss rate, and cooking loss rate. The results indicated that the 150 kDa chitosan dip-coating demonstrated superior performance in extending the shelf life of Monopterus albus by preserving tissue structure, reducing cellular damage, and moisture loss. This research would supply new insights into widening chitosan as natural preservative in aquatic product preservation.
