STUDY ON TYPES OF EXTRACTION FOR ESSENTIAL OILS AND VEGETABLE OILS

Abstract

Studies shows that for each type of oil there is a proper extraction, we want to test another method for each oil and analyze efficiency and yield of the extraction if it does occur. So, we will carry out scientific research, with the objective of verifying the efficiency of the mechanical and solid-liquid process in the extraction of lipids to produce essential and vegetable oils, being characterized as a qualitative process. We will use as a sample the avocado fruit, which according to research, proved to be a fruit rich of lipids, since is easy to extract, it has a lot of possible extraction methods. For the analysis of the optimization of the extraction and quantity of lipids removed, we will use two diversified methods, a mechanical process that will take place through cold process, centrifugation and decanting of the fruit pulp and a solid-liquid process in which we will subject the sample to a certain solvent, located inside a volumetric flask that will be connected to a Soxhlet device and a condenser and will be heated with the aid of a heating blanket. The fruits will be harvested when not yet ripe and have reached their maturation process at room temperature, with little humidity and light, so that the pulp is removed in its best quality. The use of cold pressing extraction allows the oil removed to have no toxic chemical compounds, having so greater purity in relation to the solid-liquid process that uses nonpolar solvents that possibly contaminated the sample even in small quantities.
