The syrup with high concentrations plays a role in causing sweetness, cementing nuts and shaping. The cementing of nuts and shaping are influenced by the viscosity of syrup and governed by the law of viscosity variation. Using an R/S plus rheology meter, the rheological properties of mixed syrups of sucrose and maltose with different concentrations ranging from 80% to 92% used for nut-candy at different temperatures were investigated. Results showed that the Arrhenius model could describe the temperature-dependence of viscosity well and the power equation could describe the effect of concentration on viscosity. In the researched ranges of temperature and concentration, the equations for viscosity as a function of t
