The advantages of supercritical CO2 extraction of ginger

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

Traditional methods

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

First, 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.

Second, 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.

Third, 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.
