The solubility of avocado oil in scCO2 was calculated from the
slope of the extraction curves in the constant extraction step, as
shown in Table 3.
The solubility of avocado oil in scCO2 as a function of temperature
and pressurewas correlated by the Chrastil equation (1982), as
written by equation (3). The parameters k, a, and b were obtained
by fitting the experimental data to the model, according to Eq. (5),
using a computer program which minimizes an objective function,
using the modified Nelder and Mead simplex method
