The effect of some factors on the performance of grapefruit essential oil obtained by microwave-assisted hydrodistillation method

Abstract

In this study, Grapefruit peel oil has many applications such as nourishing and stimulating hair. Recently, new methods of extracting essential oils have been increasingly developed to replace traditional methods. In this study, optimizing the oil yield from bark peel was studied by the method of hydrothermal distillation with the support of microwave (MAHD). We found that the optimal oil yield of grapefruit peel was 2% corresponding to factors such as the ratio of raw materials and water of 1: 4 (ml/g), extraction time of 45 (minutes) and capacity. microwave is 450 (W). In addition, the essential oil was also taken to measure iron gas with spectral distribution with the chemical composition of grapefruit peel oil such as limonene (96.491%), followed by β-myrcene (1.644%), α-Phellandrene (0.793%), 1R-α-Pinene (0.686%), Sabinene (0.248%). Microwave assisted hydrolysis method (MAHD) provides an essential oil with higher compound content and significant cost savings, in terms of time, energy and plant material. MAHD is a green technology and appears as a good alternative to extracting essential oils from aromatic plants.
