Abstract The effect of taro additives (taro pulp and starch) on the gel properties of Trachinotus ovatus surimi was studied. The pattern of changes in whiteness, gel strength, water-holding capacity (WHC), water content and transverse relaxation time (T2) were analyzed. The results showed that the sensory quality of the surimi gel added with taro pulp was better, the gel strength and WHC of the surimi gel added with taro starch were better, the addition of taro could reduce surimi gel whiteness. Low field nuclear magnetic resonance (NMR) showed that with the addition of taro additives, the transverse relaxation time T22 and T23 decreased, while T21 increased; the peak area S21 and S22 increased, while S23 decreased, indicating that the fluidity of free water in the gel decreased.
