Supercritical fluid extraction assisted by cold pressing from clove buds: Extraction performance, volatile oil composition, and economic evaluation

Supercritical fluid extraction assisted by cold pressing (SFEAP) is presented for obtaining volatile oil from clove buds at 150 bar, 40 °C, and using two torques (40 and 80 N.m). As the best condition, SFEAP with 40 N.m provided an oil yield of 22.19 g/100 g buds containing Eugenol (57.7 wt.%), E…
