Various ratios of guar gum to locust bean gum were used with nine combinations of sucrose, 36DE corn syrup and 42 high fructose corn syrup (42 HFCS) in a standard ice cream formulation. It was demonstrated that differences in the structure (defined as change in adiabatic compressibility) of the mixes could be determined by measuring the acoustic parameters of sound velocity and density. From these parameters adiabatic compressibility was calculated. Data indicated an increase in mix structure when the guar to locust bean gum ratio was increased. This occurred with each of the nine sweetener combinations. With respect to changes in sweetener, the amount of corn syrup had little effect on structure. An increase in 42 HFCS, however, increased the structure. Differences in structure were attributed to the changes in the structure of water contained in the mix.
