Introduction Ginger (Zingiber officinale Rosc.) is a perennial herbaceous plant of the Zingiberaceae family. As a spice with a long history, it is widely used. Ginger pictures Ginger pictures Used in food cooking. China is not only one of the main producers of ginger, but has also gradually become one of the main exporters of ginger. However, ginger is difficult to store and easily rots and deteriorates. During the harvest season, the ginger producing areas suffer great losses. Ginger is mostly used as a seasoning. In my country, raw ginger or ginger powder has always been the main consumption, and the utilization rate is extremely low. Using various extraction methods to extract the beneficial substances from ginger makes it more convenient for use in industries and other sectors, which is ginger essential oil. Ginger essential oil is a light yellow or green liquid. Traditional methods The methods for extracting ginger oil products from ginger mainly include steam distillation and solvent extraction. The steam distillation method uses Dalton's law of partial pressures. Fresh or dried ginger is crushed before steaming, and then steam is introduced under normal pressure or pressure to distill the ginger oil at a temperature below its boiling point. This method mainly obtains the more volatile essential oil in ginger, while some phenolic derivatives such as gingerol are difficult to be distilled out with water vapor due to their unique molecular structure. Therefore, the steam distillation method can only extract some flavor substances in ginger, and the high temperature of the distillation process will cause harmful changes in the composition, odor and flavor of the ginger oil. The chemical composition of the ginger oil obtained by the solvent extraction method is greatly related to the solvent selected, but the solvent method is easily contaminated by residual solvents and will precipitate and discolor, and its use is subject to certain restrictions. In summary, the ginger oil products produced by the traditional ginger processing method have obvious defects: 1. The limitations of the processing method itself make it difficult to achieve color, aroma and taste; Second, due to the lack of unified standards and different extraction methods, the product components and contents will vary greatly, thus affecting their physical properties and causing great trouble to terminal use. You can also rub it on your head to treat hair growth. application Standardized ginger essential oil is mainly used in the processing of ginger-flavored foods, such as instant noodle seasoning packets, meat products, flavors and spices, pickling, baking, beer, ginger-flavored drinks and other foods, and is also used in medicines and daily chemical products. It is an ideal high-end spice seasoning. With the development of the food industry, high-quality and standardized ginger essential oil will surely be highly praised by people. |
