OLEORESIN FROM GINGER USING EXTRACTION PROCESS WITH ETHANOL SOLVENT
Abstract
Use of ginger was grow commercially in processing that use appropriate technology. Refining of oil
and ginger oleoresin from ginger rhizome growing to be a raw material in pharmaceutical companies
manufacture drugs. Components of chemical compounds contained in ginger consists of oil evaporated,
oil does not evaporate and starch. This research aims is to extraction of ginger oleoresin. Variables that
performed in this study include the extraction temperature (30, 40, 50 and 60 ° C) and extraction time (1,
1.5, 2, 2.5 and 3 hours). While the operating conditions involved the comparison of materials and
solvents of etanol 70%, materials size measure ± 40 mesh, ginger type of emprit and speed turn around
60 rpm. Ginger powder counted 300 gram and solvent 1500 ml entered into ekstraktor with time and
temperature of extraction according to variable. After finishing result of extraction entered into rotary
vacuum evaporator to be dissociated between oleoresin and solvent. Analysis batchwise to specific gravity,
refractive index, rendemen and % gingerol. The best condition got by at oleoresin extraction of ginger
with temperature of extraction 40oC and time of extraction 3 hour, where got specific gravity 0,9012 gr /
cm3, refractive index 1,4769, rendemen 9,98% and % gingerol 33,23%.
