Abstract This study aimed to study the effects of tumbling time and addition of 0.8% lysine (Lys) on the water holding capacity, texture and color of low-salt cooked ham. Results showed that the cooking loss of ham decreased as tumbling time increased. Moreover, addition of Lys increased the water holding capacity, which might be attributed to the increase in the content of immobilized water as reflected by nuclear magnetic resonance (NMR) analysis. Limited improvement in the texture were observed for these treatments. Increasing tumbling time led to a decrease in redness. Meanwhile, longer tumbling time or addition of Lys caused the transition of α-helical to β-sheet and decreased the content of total sulfhydryl, indicating their important roles in inducing the formation of protein gels. Therefore, increasing tumbling time to 40 min and addition of 0.8% Lys show great potential in developing low-salt cooked ham with improved quality.
