The Extraction Pressure Affects the Performance, the Physico-Chemical Characteristics and the Chemical Compounds of the Essential Oil of Punamuña (Satureja Boliviana)

EasyChair Preprint no. 3406

Abstract

Essential oils have become an integral part of our life, the extraction of which can enrich or reduce the presence of some components. For this reason, he investigated the effect of different levels of extraction pressure (6, 10 and 14 psi) with steam on the oil's performance, the physico-chemical characteristics and the chemical compounds for the punamuña essential oil (Satureja boliviana). The highest performance was obtained using an extraction pressure of 10 psi (0.38%). Density, acidity, peroxide index and refractive index were significantly influenced by extraction pressure. Thirty-two chemical compounds were identified using the three extraction pressures: pulegone, isomenthol and menthone at 6 psi; L-menthone, menthone and pulegone at 10 psi; and pulegone, thymol and p-mentona at 14 psi. Essential oils are influenced by the extraction pressure; here it was observed that a higher yield and number of chemical compounds are obtained at 10 psi, which in turn also results in adequate physical-chemical characteristics such as density, acidity and peroxide index that would also be related to the compound’s extracted chemicals.
