2.2 Laboratory SFME apparatus and procedure
SFME was performed in a laboratory microwave oven (NEOS, Milestone, Italy). This
is a 2.45 GHz multimode microwave reactor with a maximum power of 900W delivered in
10W increments. During experiments, time, temperature, pressure and power were controlled
by the software. The experimental SFME variables were optimised in order to maximize the
essential oil yield. In a typical SFME procedure performed at atmospheric pressure,
