Abstract

The invention discloses a method for extracting CBD full-spectrum oil from industrial hemp mosaic leaves, including a pre-treatment process and a post-purification process, wherein the pre-treatment process includes a pre-treatment process, an extraction process, a decolorization process, a concentration process and a decolorization process. Wax link, wherein the pretreatment link includes impurity removal blanching, hot rinsing, slitting and drying links, the method adds a pretreatment process, and the pretreated industrial hemp mosaic raw materials reduce a large amount of cellulose, chlorophyll, Wax and other impurities reduce the difficulty of separation and extraction in subsequent steps, greatly reduce the amount of extraction solvent used, lower operating costs, and improve the extraction rate of CBD and the yield of CBD components in the final full-spectrum oil.

Description

technical field [0001] The invention relates to a method for extracting CBD full-spectrum oil from industrial hemp mosaic leaves. Background technique [0002] CBD, cannabidiol, English: cannabidiol, is a pure natural ingredient extracted from cannabis plants, and is an extract of cannabis leaves without further purification and separation. In addition to CBD, hemp leaf extracts also contain other cannabis. Nutrients (such as CBN, CBG, CBI, CBCVA, THC), terpenes and aromatic compounds, CBD has the ability to block the adverse effects of certain polyphenols on the human nervous system, and has the ability to block breast cancer metastasis, treat epilepsy, anti-inflammatory A series of physiologically active functions such as rheumatoid arthritis and anti-insomnia have a good effect on the treatment of multiple sclerosis. [0003] CBD full-spectrum oils are typically thicker, darker in color, and have the vegetal flavor of cannabis. [0004] At present, the extraction method...
