Advantages Of Supercritical CO2 Extraction Of Ginger Oil


Ginger is a kind of hot seasoning that we are familiar with.

It is native to Asia and is one of the earliest seasonings from the East to the West. It includes India, China, Japan, Malaysia, Queensland, Florida, and India and China. The most pharmacological properties, but widely used in cooking and recipes. The traditional Chinese medicine uses Jiangyan to remove dampness and coldness.

Ginger essential oil extraction method

Extracted from ginger, ginger oil products mainly include steam distillation and solvent extraction.

Steam distillation

Steam distillation uses Dalton’s law of partial pressure to break up fresh ginger or dried ginger before steaming and then steam or steam under normal pressure or pressure to distill ginger oil below its boiling point.

The method mainly obtains volatile essential oils in ginger, and some phenol derivatives such as gingerol, because of its unique molecular structure, are difficult to steam out with steam, so the steam distillation method can only extract part of ginger Flavor substances, and the high temperature of the distillation process, will make harmful changes in the composition, odor, and flavor of ginger oil;

Solvent extraction method

The chemical oil contained in ginger oil obtained by solvent extraction method has a great relationship with the selected solvent, but the solvent method is easy. Contaminated by residual solvents and precipitates discoloration, its use is limited.

In summary

The ginger oil products produced by traditional ginger processing methods have obvious defects:

First, the limitations of the processing method itself make it difficult to achieve color, smell and taste;

Second, due to the lack of a unified standard and different extraction methods, the composition and content of products will be very different, which will affect their physical properties and cause great trouble to the use of the terminal.

Supercritical CO2 extraction

Modern ginger essential oil is extracted with supercritical CO2 extraction of ginger essential oil, using CO2 as a solvent to extract ginger essential oil in a supercritical state.

Due to the characteristics of CO2 and room temperature and green extraction process, the essential oil of ginger Compared to ginger oil products produced by traditional processing methods, there are three major advantages:

Ensures the stability

The standardization of the gingerol index ensures the stability of the end product.

The supercritical extraction of ginger essential oil using gas-phase and liquid-chromatographic treatment systems was performed using an area normalization method to determine the relative contents of various components of ginger essential oil, and it was determined that the content of characteristic ingredient 6-concentrated gingerol was used as the product standard.

Ginger essential oil product standardization, the resulting ginger essential oil aroma is pure natural, flavor integrity, quality and stability, to maximize the retention of ginger flavor ingredients, is a highly concentrated original product.

Traditional processing methods are affected by factors such as variety, origin, and storage of ginger, resulting in inconsistent intensity of gingerol and inability to ensure consistent and consistent end product.

Ginger essential oil, which is controlled by the ginger character of ginger, is completely spicy to ginger. Consistency of flavor.

Natural sterile health

Natural, sterile health, long shelf life, convenient storage. The entire production process is carried out at near normal temperature and high pressure without solvent contamination.

In the production process, almost no viable bacteria can survive, which avoids the disadvantages of using traditional spice flavoring for sterilization.

Easy to use

High concentration, small size, easy to use.

High-concentration products can be diluted and compounded into various products such as oil-soluble, water-soluble, and oil-water soluble, which facilitate the use of the terminal.

Skin efficacy

Helps dissipate blood stasis and heals wounds; conditions oily skin. Not suitable for facial skin care, adjustable and shampoo in shampoo, can go to the wind, headache; available base oil diluted massage to dispel blood stasis, treatment of trauma. Improve memory and promote hair growth. A few drops of ginger essential oil are added to the hot water in the foot bath to achieve the purpose of activating the meridian of the blood circulation, and to achieve the effect of removing beriberi and foot odor.

Physiological efficacy

Aphrodisiacs are valuable in the treatment of incompetence, improve menstruation, can also be used for postpartum care to eliminate accumulated blood clots; especially help to improve the state of body moisture, excessive fluid, such as influenza, more And runny nose can also relieve sore throat and tonsillitis.

Psychological effect

Warm emotions make people feel sharp and enhance their memory, and they are in a good mood.
