Modern ginger essential oil is extracted by supercritical CO2 extraction method, which USES CO2 as the solvent to extract ginger essential oil from ginger under supercritical state. Due to the characteristics of CO2 and normal temperature and green extraction process, ginger essential oil has three advantages compared with ginger oil products produced by traditional processing methods:

I. standardization of gingerol index to ensure the stability of terminal products. Supercritical fluid extraction of ginger essential oil in the gas phase, liquid phase chromatographic system, as measured by the area normalization method ginger essential oil relative content of components, and to determine the feature components of 6 - gingerol content as product standards, making ginger essential oil product standardization, the resulting ginger essential oil fragrance is pure natural, full flavor, stable quality, maximum limit retains the ginger flavor ingredients, was the original high concentrated product. The traditional processing method is affected by the ginger variety, place of origin, storage and other factors, which leads to inconsistent gingerol strength and cannot guarantee the stability and consistency of the terminal product. However, the ginger essential oil controlled by gingerol is able to achieve the consistency of ginger's spicy flavor.

Pure natural, sterile health, long shelf life, convenient storage. The entire production process was carried out at close to room temperature and under high pressure with no solvent pollution, and almost no live bacteria could survive in the production process, avoiding the malpractice of sterilization by using traditional xiangxin seasoning.

High concentration, small size, easy to use. High concentration products can be diluted and mixed into various products such as oil solution, water solution and oil and water solution at will to facilitate the use of terminals. Articles come from the Internet
