Abstract    According to the literature, the simple Equations of State (EoSs) like Soave-Redlich-Kwong (SRK), Peng-Robinson (PR) and the other ones need some data such as intermolecular energy parameters, critical properties, acentric factors, and mole refractions. Since these data are not available for a lot of high molecular weight molecules, there are some limitations in applying them. One of these molecules is β-carotene which is a polar biomolecule. In this research, the solubility of β-carotene (as a sample) in high-pressure carbon dioxide was calculated by a two-parameter EoS and compared with the experimental data. The results showed that the two-parameter Mohsen-Nia-Modarress-Mansoori (MMM) EoS was an accurate one for the solubility prediction in supercritical and slightly near critical conditions for the multicomponent systems. The binary coefficients of β-carotene and carbon dioxide in various pressures and temperatures were obtained by the genetic algorithm.
