In order to explore the effect of metal ion nutritional fortifiers on the quality of frozen surimi,we used grass carp surimi frozen in a 4 mT magnetic field assisting environment as raw material,added three different metal ion nutrient fortifiers,namely,magnesium citrate,zinc citrate,and ferrous citrate,and analyzed the changes in quality characteristics such as relative magnetic permeability,water holding ability and texture of surimi.The results showed that metal ion nutrient fortification could improve the quality of frozen surimi,and the relative magnetic permeability increased by 13.59%,water holding capacity by 7.08%,and hardness by 26.60% in the ferrous citrate group compared with the control group.This study provides theoretical guidance for the addition of metal ion nutritional enhancers to improve the frozen quality of surimi.
