EXTRACTION OF GINGER (Zingiber officinale Roscoe) OIL AND RESINS FOUND ON THE PARANA COAST (BRAZIL)

Abstract

The present work describes the processes used for the obtention of ginger oil and resin, extracted from its rhizome and processed. The analysis were conducted with natural rhizome, harvested, washed and mantained by refrigeration until the moment of use and dried in an air stove until it reaches moisture content of 10% (m/m) and finally stored by refrigeration. The obtention processes of oil involved the extraction with organic solvents, to achieve the resins and oil, and steam stripping for oil. The results showed that the best quality of the oil is achieved by the steam stripping process, with 2 hours of extraction and that the higher quantity of resin is obtained by the use of propanone as solvent and extraction time of 3 hours.
