Abstract

The invention relates to a method for extracting chrysanthemum essence oil by a salt leaching method. The method takes chrysanthemum as a raw material, and the essence oil can be obtained through several times of distillation. The raw material chrysanthemum is budding chrysanthemum; the method comprises the following steps: before distillation, using a common salt aqueous solution with mass concentration being 5-20% for immersing the raw material for 3-5 hours, heating the raw material to the temperature of 50-70 DEG C, slaking the material for 5-10 minutes, and distilling the material for 4-10 hours, and collecting the product to obtain the chrysanthemum essence oil fraction. During a whole extraction process, no organic solvent is used, chrysanthemum oil purity is guaranteed, pollution of the chrysanthemum oil can be avoided, and at the same time, the whole production process is clean and pollution-free.

Description

technical field [0001] The invention relates to a method for deep processing of agricultural by-products, in particular to a method for extracting chrysanthemum essential oil by salt soaking. Background technique [0002] Traditionally, chrysanthemum has three major uses, one is to beautify the environment and be used for people to watch, the other is to process chrysanthemum tea, as a health drink, chrysanthemum tea is also one of the important consumption channels of chrysanthemum, and the third is to use it in traditional Chinese medicine. [0003] Chrysanthemum oil has the natural fragrance of chrysanthemum, and is mostly used in the production of high-end cigarettes and flavors. The preparation of chrysanthemum oil is mostly organic solvent extraction, and the organic solvent mixed in the extraction process is difficult to remove, which affects the quality of chrysanthemum oil to a certain extent. Contents of the invention [0004] The technical problem to be solved ...
