OPTIMIZATION STUDY ON MATHEMATICAL MODEL OF CYMBOPOGON WINTERIANUS ESSENTIAL OIL EXTRACTION BY STEAM DISTILLATION

Citronella essential oil derived from Cymbopogon winterianus is one of the most widely traded essential oil in the aroma sector. As these oil content more than 50 terpenoidal blends and constituents, the oils are high in demand in aroma industry either as perfumery agent or as source of lead molecul...
