Sažetak
The primary objective of this investigation is influence of parameters of high intensity ultrasound and their interactions with constant frequencies of 30 kHz on physical properties of sheep milk. Influence of high intensity ultrasound is followed by given process parameters: amplitude (A=20, 60 and 100 %), time of treatment (t = 2, 6, 10 and 15 minutes), cycles (0, 6 ; 0, 8 ; 1) and probe diameters (d = 7, 10 and 14 mm) on changes of temperature, pH – value and density. Influence of process parameters and their interactions are shown with Probability plot expressed over p – values and β – standardized coefficient (ANOVA) and calculated using linear and quadrate model. Process parameters and their interactions have influence on increasing of temperature of sheep milk. Influence on decreasing of pH – value is obtained with maximum intensities of 7mm probe. Influence of interactions between amplitude and cycles results on increasing of density which is indicated with high β – value. Obtained results indicated that linear model have better interpretations of influence of process parameters on temperature while quadrate model have better interpretations of process parameters on pH – value and density.
