Why Select Ginger Essential Oil by CO2 ?

Comparison of Ginger Oil by Supercritical CO2 and by Distillation

  Items       Ginger Oil by Distillation        Ginger Oil by CO2
 Raw Material  Purchased generally from farmer market  Collected from ginger plantation base of  our own
 Maybe from many farmers, with bad  quality for undefined origin,  uncontrollable processing;  Planted in the clean and fresh air  moun-  tain area,together with standardized  growing, collecting,screening and  processing;
 Possibile hazard in pesticides and heavy  metals  High quality, absolutely safe for people.
 Manufacture  Method  Steam distillation at high temperature  by CO2, i.e. by the Supercritical Carbon  Dioxide Extraction Technology--Whole  production process is at less than 35C

 Hot water or steam is the media for oil 

 production

 Only use 99.9% carbon dioxide as  solvent, no solvent residual;
 Some undefined chemical changes and  heat decomposition during production  at high temperature;  No chemical changes and decomposition  during production;
 Apperance  Light yellow color  Light fresh-yellow color
 Ordor  Not fresh, not nature,not characteristic  fragrance of ginger  Strong, very fresh and characteristic,  pleasure ordor for any people
 Strength of  Fragrance  Low  High
 Microbe  Generally polluted by bacteria  Nearly no bacteria in the product for the  good sterilization effect of supercritical  carbon dioxide at high pressure.
 Physical-  chemical  Properties  Specific Gravity: 0.8701  Specific Gravity: 0.8812
 Refractive Index: 1.4892  Refractive Index: 1.4914
 Optical Rotation: -25.961 degree  Optical Rotation: -43.38 degree    Better  optical rotation !
 Medicinal  Functions   Infirm  Very good for
 Ratio of  Performance  to Price  Low  High. For example, to use to diminish  inflammation, relieve nauseacombat  motion sickness, reduce dizziness,limit  flatulence, control chronic pain, ease the  pain of muscle aches and so on.
 Application  Mainly be used to common and low-  value products  The best additive for high-value products  such as cosmetic and fragrance water.
 Convenience  to Use  General  Best
 Stability and  Shelf Life  Not stable and shelf life is generally less  than 6 months at room temperature  Very stable and with long shelf life (NLT  18 months) at room temperature
 Remarks:  Herein, by CO2 means "supe rcritical carbon dioxide extraction technology".
