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.　©　2024　Editorial　Department　of　Food　and　Machinery,　shipin　yu　jixie.　All　rights　reserved.
