Objective:Improve 3D printing performance and gel properties of silver carp surimi system.Methods:By optimizing 3D printing parameters,the 3D printing process is associated with material rheological properties and 3D printing performance.The effects of sodium chloride addition on rheological properties,3D printing properties,gel strength,moisture properties and microstructure of silver carp surimi were investigated.Results:The addition of sodium chloride decreased the loss modulus of surimi in a dose-dependent manner,but significantly improved the shear recovery performance,reduced the cooking loss of surimi system and increased the water retention of surimi system.The best gel strength and the densest microstructure of silver carp were obtained when the sodium chloride content was 2.5％.Conclusion:Adding proper amount of sodium chloride can improve the 3D printing performance and gel properties of surimi products.
