In this study, an attempt was made to modify the existing ultrasound method (two-velocities method, TVM) for estimating the proximate chemical composition of meat products by replacing one of the two sound velocity measurements with a measurement of product density at the same temperature (velocity-density method, VDM). Both methods were used to determine the chemical composition of the same five batches of three selected meat products made in Poland: pork canned ham, pork 'Krakowska' sausage and pork 'Podwawelska' sausage. In all three products, the mass percentage of every ingredient determined by TVM differed significantly from the results of chemical analysis, whereas the mass percentage estimated by VDM did not differ significantly from the results of chemical analysis in any of the tested products. The study proposes a new, more accurate method for determining the proximate chemical composition of meat products. The method relies on measurements of product density, but it eliminates the need for measuring sound velocity at two different temperatures. (C) 2016 Elsevier Ltd. All rights reserved.
