Abstract
The supercritical fluid extraction of aroma compounds from basil (Ocimum
basilicum L.) was studied. Response surface methodology was used to optimize
the parameters of the process. Full factorial design was applied to evaluate
the effects of two independent variables (pressure and temperature) on the
extraction yield and linalool yield. From the response surface plots,
pressure and temperature exhibited independent and interactive effect on the
extraction yield. The optimal conditions to obtain the highest extraction
yield (1.91%) of O. basilicum were the pressure of 29.7 MPa and temperature
of 59.2oC, whereas the highest yield of linalool (1.998 g•kg-1) was obtained
at the pressure of 20 MPa and temperature of 40oC. The experimental values
agreed with the predicted ones, indicating suitability of the response
surface methodology for optimizing the extraction process. [Projekat
