  • Solubility of binary solid mixture ▫$\beta$▫ carotene-capsaicin in dense ▫$CO_2$▫
    Škerget, Mojca ; Knez, Željko
    The equilibrium solubilities of binary solid mixture [beta]-carotene-capsaicin and supercritical CO2 were measured using a static-analytic method. The solubilities of solid mixture components in CO2 ... were determined at 25 and 40 oC in the pressure range from 100 to 300 bar. Measurements were performed at two mass ratios of solid components [w(carotene):w(capsaicin) 1:1 or 2:1, respectively] and it was found that the mass ratio of both components did not influence the equilibrium solubility. The equilibrium data of the ternary system [beta]-carotene-capsaicin-CO2 were compared to the equilibrium solubility data of the binary systems [beta]carotene-CO2 and capsaicin-CO2. It could be observed that the solubility of capsaicin was lower in the presence of [beta]-carotene. The solubility of [beta]-carotene in CO2 did not change in the presence of capsaicin. As shown in the examples in the paper, the data presented are important for designing the separation process of coloring and hot components from paprika.
