The speeds of sound and densities of nutrition Solutions containing (50 to 200) mg.mL(-1) of carbohydrates, (10 to 40) mg.mL(-1) of proteins, and (10 to 40) mg.mL(-1) of lipids at different temperatures were measured. Isentropic compressibilities were calculated from the experimental results. The results show that rho, u, and kappa(s) depend on the temperatures and compositions of carbohydrates, proteins, and lipids. These results may provide an opportunity to use acoustic parameters For the characterization of lipid, carbohydrate, and protein content in nutrition solutions.
