Many studies on the composition and efficacy of essential oils have been performed for a long time. Essential oils, in general, have complex compositions containing hydrocarbons and oxygenated compounds. These compositions are closely related to their characteristic odors and
flavors. Essential oils have been widely used for pharmaceutical, cosmetic, food, perfume and agricultural industries because of their antiviral, antibacterial and antifungal activities in addition to their unique odor and flavor. In the field of medicine, they have been found to have an excellent ability to treat tuberculosis, indigestion, infection, loss of appetite, insomnia, hypertension and rheumatism. In the present study, poly(ethylene glycol) (PEG) microparticles containing
coriander (Coriandrum sativum) essential oil were prepared using supercritical particles from gas saturated solutions (PGSS) technique to improve the stability of coriander. The effects of temperature, pressure, nozzle geometry and molecular weight of PEG on the morphology, entrapment efficiency and crystallinity of the coriander essential oil - loaded PEG microparticles were examined.
