However, there was a decreasing trend from 55 to 60 °C, probably because the increase in temperature could lead to a large decrease in the subcritical n -butane density, with a consequent decrease in seed oil solubility [ 14 ].
There was an increasing trend from 40 to 55 °C and this was probably due to the decrease in the solvent viscosity and the increase of the lipid solubility at higher temperatures.
