Abstract

The invention discloses an extraction method for a plant aromatic stock solution. Extracts of the aromatic stock solution comprise lavender, eaglewood, rose petal, mint leaf, clove and sandalwood. Aroma compounds are extracted by using hydrolase degradation separation and aroma production technology. Meanwhile, the invention brings forward a preparation method for solidified essence from the aromatic stock solution by using a spray-drying process. Compared with a traditional extraction process, the extraction method provided by the invention has the advantages of a short period, high purity, rich fragrance, etc.

Description

technical field [0001] The invention relates to the field of material extraction and compound processing, in particular to a method for extracting plant fragrance stock solution and preparing solidified essence from the fragrance stock solution. Background technique [0002] Traditional plant extraction methods include maceration, reflux, Soxhlet extraction, steam distillation, etc. These extraction methods and processes have the advantages of simple operation, but also have the disadvantages of long extraction period, large loss of active ingredients, and Disadvantages such as high amount of impurities. Contents of the invention [0003] In view of the above problems, the primary purpose of the present invention is to propose a method for extracting plant aroma stock solution, which has the advantages of short cycle, high purity, strong aroma, etc., which is specifically realized through the following technical solutions: [0004] A method for extracting a plant fragranc...
