Özet

Full mechanical characterization of ketchup (K), processed cheese (PC), and K-PC mixtures was established to obtain internal structure of these samples using creep and recovery analysis along with oscillatory measurements. To simulate the viscoelastic behavior of these samples as a function of PC concentration and temperature, Burger model was successfully used to describe the effect of these factors. The effect of temperature on creep properties of K-PC mixtures was clearly explained by the Arrhenius relationship. Exponential model described better than the power-law model with respect to effect of concentration ranges; but for description of temperature ranges, the opposite was true. Remarkable changes in the mechanical properties of K-PC mixtures were determined using the thermo-mechanical simulation model, revealing that the PC and temperature levels could remarkably change the internal structure and deformation properties of the K-PC mixtures. The final percentage recovery also changed remarkably with concentration and temperature. (C) 2012 Elsevier Ltd. All rights reserved.
