PENGAMBILAN OLEORESIN DARI AMPAS JAHE (HASIL SAMPING PENYULINGAN MINYAK JAHE) DENGAN PROSES EKSTRAKSI

Abstract

Abstract During this time the ginger oil distillation waste are only used as fire wood for the distillation process. It is predicted that this waste still contain oleoresin. Oleoresin is the mixture fixed oil (3 – 4 %), essential oil (1 – 3 %), resin etc. This research aims to find the most affecting variable and the optimum operation condition in the extraction processing oleoresin from ginger oil distillation waste. The research is planned to use the factorial design method 2 levels and 3 independent variables i.e.: temperature (30-60 oC), time (2-6 hours) and solvent volume (300/150- 700/150) ml/gr the weight of ginger waste. The experiment quantities which must be carried out are 8 runs. The observed parameters are weight, density and refraction index. The three independent variables give positive effect/ increase the product and time is the most influential variables. Then the optimization process is carried out to get the optimum operation condition by varying the extraction time. The optimum operation condition of oleoresin extraction is 5.5 hours, temperature 60 oC and solvent volume 700ml/150 gr the weight of ginger waste. The number of oleoresin which can be obtained volume 4.1 ml, weight oleoresin 2.7 grams, density 0.67 grams/ml, and refraction index 1.4744. GCMS analysis shows that the zingeberence content is 14.91%. Key words : ginger-oleoresin-extraction
