Extraction method of osmanthus fragrans floral substances and floral essence solution obtained by extraction method

Abstract

The invention provides an extraction method of osmanthus fragrans flower fragrance substances. The method comprises the following six steps: preparation of a production field and supporting facilities, collection and temporary storage of osmanthus flower buds, canning and sealed storage of the osmanthus flower buds, extraction of osmanthus flower fragrance substances, acquisition of an osmanthus flower fragrance element solution, identification of the osmanthus flower fragrance element solution and obtaining of a finished product. By adopting the method, the osmanthus fragrans floral substancecan be extracted on a large scale at low cost, and the extraction rate is up to 90% or above. The osmanthus fragrans floral essence solution obtained by the method is high in yield; the cost is low,and the molecular structure and chemical components of the osmanthus fragrans flower fragrance substance are not damaged; therefore, the osmanthus fragrans floral essence solution contains high-concentration, high-purity and high-fidelity osmanthus fragrans floral substances, can be used as a raw material for further extracting osmanthus fragrans essence and osmanthus fragrans essential oil, can also be directly applied to various high-grade cosmetic products, and can also be used as spice in the fields of foods, daily necessities and the like.

Description

technical field [0001] The invention relates to a method for extracting sweet-scented osmanthus fragrance substances and an sweet-scented osmanthus fragrance solution obtained by the method, belonging to the technical field of extraction of natural floral fragrance substances. Background technique [0002] Osmanthus fragrans is native to China, and it is the most elegant and noble fragrant flower with Chinese characteristics, and it is also one of the ten most fragrant flowers in the world.

Problems solved by technology

The steam distillation method is to immerse osmanthus in water for distillation to obtain essential oil. The quality of osmanthus essential oil processed by this method is poor, the loss of top aroma is serious, the content of impurities is high, and the aroma is not pure enough.

The organic solvent extraction method is to extract the extract with an organic solvent first, then use ethanol to dissolve the floral substances in the extract, and then remove the ethanol to obtain the essential oil. This method has cumbersome steps and high implementation costs.

The carbon dioxide supercritical extraction method is to heat and pressurize carbon dioxide to form a liquid, mix it with osmanthus, and finally recover the carbon dioxide to extract the essential oil. This method is complex in process and requires high production equipment.

In addition, the yields of osmanthus osmanthus essential oil obtained by the above three methods are too low, and about 80-100kg of osmanthus osmanthus is needed for every production of 100g osmanthus osmanthus essential oil, so the product is expensive and unfavorable for popularization and application
