Problems solved by technology

However, in the process of making red ginseng from ginseng, the volatile oil is taken out with the water vapor during the steaming process, and nearly 70% of the volatile oil is lost. It is a pity to throw away this part of by-products as waste.
For example, Baishan City has 25,000 tons of fresh ginseng processed into red ginseng every year, and the annual output of red ginseng is about 5,000 tons, while the volatile oil content in ginseng is about 0.1%-0.5%, and most of them are concentrated in the ginseng skin. The medium volatile oil is evaporated together with the water vapor and discharged, resulting in a great waste of resources

Abstract

The invention discloses a method for extracting ginseng essential oil from ginseng processing wastes, and solves the technical problem that volatile oil in the red ginseng processing process is evaporated together with water vapor and discharged to cause great waste of resources, and belongs to the technical field of ginseng essential oil extraction. The method comprises the steps of steamed ginseng water collection, extraction, separation and concentration, distillation and refining, so that refined ginseng essential oil is obtained. According to the method, the byproduct of water vapor in the ginseng processing process is taken as an object, condensing equipment is used for collection, the extraction of ginseng volatile oil is carried out through the steps of solvent extraction, separation, distillation and the like, so that the purposes of changing waste maters into things of value and reducing the cost are reached, and the valuable resource is preferably utilized.

Description

technical field [0001] The invention relates to the technical field of extracting ginseng essential oil, in particular to a method for extracting ginseng essential oil from ginseng processing waste. Background technique [0002] Ginseng is a famous and precious Chinese medicinal material with high medicinal value and high market price. Its whole plant contains volatile oil (i.e. essential oil). Nervous and anti-tumor effects can accelerate the production of glucosamine polymerase in the skin and activate skin regeneration. Ginseng essential oil has the function of skin care and health care. It is used in cosmetics and skin care products. Ginseng essential oil is absorbed by the human body through the penetration of the skin, so as to enter the blood circulation and metabolism, promote the development and nutrition of skin cells, increase skin luster, and have anti-wrinkle and anti-cold properties. Pharmacological effects with protection from UV radiation. [0003] The curr...
