In this study, the possibility of using ultrasound technology as an alternative to traditional pasteurization and homogenization in ice cream production was presented. Three types of ice cream with different proportions of oleogel (5, 6, and 7%) prepared using tomato seed oil were studied. The fatty acid contents of the oil were analyzed. Using chemical analysis, dry matter, fat, protein, dietary fiber, ash, and pH of the ice cream samples were determined. The physical analysis included analysis of the ice cream samples using a differential scanning calorimeter (DSC) and determination of their first drop time, complete melting time, overrun, viscosity, hardness, and adhesiveness. The structure of the samples was evaluated using scanning electron microscopy. Fourier transform infrared spectroscopy spectra were measured using a dedicated QATR-S Single-Reflection ATR ACCESSORY with a diamond prism. With the increase in the proportion of oleogels, the fat and carbohydrate contents, the amount of freezable water, and the overrun of the samples were increased, whereas their viscosity and hardness were decreased. Oleogels were found to be a promising alternative to fat in ice cream rich in unsaturated fatty acids, and the ice cream samples prepared using ultrasound pasteurization showed lower overrun and viscosity and higher hardness.
