The invention relates to a novel process for the production of oil and oleoresin from fresh Ginger Rhizomes ( Zingiber officinale Roscoe). The essential oil and oleoresin has far superior flavour qualities to the ginger oil and oleoresin hitherto known and produced commercially elsewhere from dried ginger. The process steps consists of preparing paste of cleaned fresh ginger, dewatering of the paste by conventional pressure technique to get aqueous phase and solid cake, recovering oil from aqueous phase and solid cake by distillation retaining the fresh flavour of ginger, combining the oil obtained from both phases to get oil, extracting the cake residue after distillation with permitted organic solvent, recovering solvent and blending the oil and solvent exttractives to get oleoresin.
