There are three major methods in extraction of edible oil from plants and fruits. The first major method is by solvent extraction with organic solvent. This method is mostly suitable for plants with low fat content. Since every species of plant consists of different composition, hence the modification of this method is needed based on different plants. Firstly, the traditional and conventional solvent extraction has been widely and commonly used for many plants. However, some studies show this method
linearly proportional with temperature. This situation happens due to the low dielectric constant nature in supercritical water, making it as a good solvent for non-polar substance like para-xylene. Therefore, it can be concluded that the reaction and yield of the reaction could be adjusted by the modification of reaction temperature. As shown in Table 1, the application of sub and supercritical water, could give a greater yield in terephthalic acid, >50%. However, the industrial implementation always

Supercritical fluids are involved in numerous industrial processes especially food industry and have a potentially wide field of new applications. The current applications of supercritical fluid include extraction processes, reaction chemistry and polymerization, food fractionation, waste recycling, soil remediation, cleaning of electronic and optical equipment parts, impregnation, dry powder coating, aerogels, nanotechnology, and crystallization and particle formation of pharmaceuticals and many
1.1. Nutraceuticals Nutraceuticals refer to extracts of foods claimed to have medicinal effect on human health. Nutraceuticals are a large and diverse class of compounds, which occur naturally in plants. Although these compounds are considered non-nutritive, many of them possess antioxidant, anti-oestrogenic, antimutagenic, anti-inflammatory and anti-carcinogenic properties that might potentially be beneficial in preventing diseases and protecting the stability of the genome. The term ‘nutraceutical’
Chemistry Department of the University of Basque Country, “High performance liquid chromatography has been successfully applied to cannabis plant extracts to identify cannabinoid compounds after their quantitative isolation by means of supercritical fluid extraction (SFE). Cannabinoid compounds and its quantity is important to know for several reasons. The most important reason being that doctors who recommend medical marijuana to their patients need this information to create a cannabis profile.
Essential oil is one of the natural products that are used by humans for a long time ago. This oil is extracted from various plants which contain a variety of essences that produce difference fragrant. Clarke (2002) defines essential oils as the “volatile product that is extracted by a physical process from single natural plant species and that has an odors and the composition characteristic of an essential oil from that species” (pp. 86-87). Essential oil is extracted by the dry distillation process
order or time of retention are the carrier gas flow rate, and the temperature. In a GC analysis, a known volume of gaseous or liquid analyte is injected into the “entrance” (head) of the column, usually using a micro syringe (or, solid phase micro-extraction fibers,
