Avaliação das metodologias de prensagem a frio, Soxhlet e Bligh Dyer, na extração do óleo de pinhão manso

Abstract

The cultivation of Jatropha has aroused a great interest for the production of oil and biodiesel. Thus, this study aimed to compare the methods of cold pressing, Soxhlet and Bligh Dyer for extraction of Jatropha oil and evaluate the physical and chemical quality of the extracted oil. The press proved to be an inefficient method of extraction , while the Soxhlet and Bligh Dyer method provided satisfactory results. Evaluation of the Jatropha oil showed viability for application as raw material in the production of biodiesel.
