Abstract: The effect of temperature and TSS on the density of Gongura leaves purees are reported. The densities of the gongura puree were determined at TSS (1.6-5.60brix) and temperatures of between 10 and 600C with 100C increments. The density of Gongura puree was strongly affected by TSS, while it was relatively less affected by temperature. Different mathematical models are try to fits the the results obtained as a function of temperature and density with varying TSS but linear model fitted best with R² >0.97.
