Problems solved by technology

In the prior art, when extracting aroma components in agarwood, the remaining residues are not processed only to obtain a certain aroma component, resulting in a waste of resources
In addition, the use of microwave-assisted method to extract aroma components has high production costs, and the use of enzymatic hydrolysis has the disadvantages of long extraction time and low extraction rate

Abstract

The invention belongs to the technical field of fragrance processing, and in particular relates to a method for comprehensively extracting fragrance components in eaglewood. The method comprises the following steps: (1) selecting raw materials, namely selecting eaglewood which grows more than 16 years and has oil lines as a raw material; (2) pretreating the raw material, namely crushing the selected eaglewood at 20-30 DEG C, screening by using a sieve of 40 meshes, adding a composite enzyme preparation and water into weighed screen underflow, adjusting the water content to be 15-20%, performing reaction for 48-60 hours at 25-30 DEG C, and drying in air so as to obtain eaglewood powder for later use; (3) performing supercritical extraction on CO2; (4) performing eaglewood primary oil separation; (5) recycling residues; and (6) extracting fermentation residues. Three obtained components, namely front cut fractions, light phases and heavy phases, and a fermented eaglewood extract can be further used as fragrance components. The method provided by the invention is high in extraction rate and high in extraction speed, and the production cost of the fragrance components is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of spice processing, and in particular relates to a method for comprehensively extracting aroma components in agarwood. Background technique [0002] Agarwood is the dry woody oily part of trees such as Thymelaeaceae (Thymelaeaceae) or Aquilaria agallocha (Aquilaria agallocha). It is a kind of wood, spices and traditional Chinese medicine. When the heart of the agarwood plant is stimulated by trauma or infection by the red oil fungus, it will secrete a large amount of resin with a strong fragrance. These parts are also called "water agarwood" because of their high density. [0003] In many parts of the world, agarwood is a precious spice, which is used to burn incense, extract spices, add to wine, or directly carve into decorations. Agarwood is also known as agarwood. Agarwood wood is hard, most of them do not sink in water, and taste slightly bitter and sweet. When burning, the smoke emits a strong arom...
