The first part of the dissertation is devoted to research of phase equilibria of triglycerides in sub and supercritical fluids. Data is key for further planning and formulation of high-pressure separation processes because they contributed to the improvement of certain industrial processes towards environmental protection and product quality. By determining the solubility and diffusion coefficient of CO2 in polymers at a given temperature and pressure, we gain more information about the phase equilibrium polymer-gas, which are important for understanding and optimizing the process parameters. In the last part of the doctoral dissertation are bound natural yellow colorant curcumin from spices and 10% of the liquid extract on carriers such as triglycerides, polyethylene glycol, cyclodextrin, cellulose, and starches. We studied different combinations of colors and a mixture of various media with supercritical CO2. We also determined the antimicrobial activity of micronized samples.
