Method for simultaneously preparing osmanthus essence, water soluble fine powder and fiber micro powder

Abstract

The invention discloses a method which adopts osmanthus as a raw material for simultaneously preparing osmanthus essence, water soluble fine powder and fiber micro powder, belonging to the technical field of extracting the effective components of plant. The method of the invention includes: (1) osmanthus is processed by the step of wet crushing to obtain osmanthus pulp; (2) osmanthus pulp is processed by vacuum distillation to obtain oil-water mixed gas and concentrated pulp; (3) the oil-water mixed gas is condensed into liquid; after the layering of oil and water, osmanthus absolute is obtained through collection, and essential osmanthus oil is obtained after the molecular distillation purification of the osmanthus absolute; (4) after the solid-liquid separation of the concentrated pulp,water containing solid slag and mixed aqueous solution are obtained; (5) after the water containing solid slag is dried, the fiber micro powder is obtained; and (6) after the membrane separation of the mixed aqueous solution, the concentrative pulp of the aqueous solution is obtained, and the water soluble fine powder is obtained after the concentrative pulp is dried. The yield of the essential osmanthus oil prepared by the invention is higher than 2 per thousand by weight, the yield of the water soluble active fine powder exceeds 4 per thousand by weight, the yield of the fiber micro powder exceeds 10 per thousand by weight, the products do not contain organic solvent and heavy metal, and the method belongs to the field of homogenization.

Description

technical field [0001] The invention discloses a method for simultaneously preparing sweet-scented osmanthus essence, water-soluble fine powder and fiber micropowder by using sweet-scented osmanthus as a raw material, and belongs to the technical field of extraction of plant effective components. Background technique [0002] Osmanthus fragrans Lour., also known as sweet-scented osmanthus, jiulixiang, and golden millet, has an elegant and strong fragrance, and has the reputation of "fragrance from the sky" and "ambergris dare not smell fragrant in the world". One of the traditional famous flowers. Osmanthus fragrans is rich in protein, fat, carbohydrate, crude fiber, multiple amino acids, vitamins, trace elements, enzymes, auxin, osmanthus alkane, carotene, aromatic oil, anthocyanins and other components. In addition to being used for viewing, osmanthus is mainly used to make various snacks, wine, tea and so on. In recent years, sweet-scented osmanthus has been widely used...

AI Technical Summary

Problems solved by technology

This method adopts the method of tissue fragmentation, which improves the yield and reduces the extraction time, but it still belongs to the category of organic solvent extraction, and the disadvantages of solvent extraction are still unavoidable

[0009] Extracting sweet-scented osmanthus essence with the above method, either the loss of volatile components is large, the product yield is low, or the volatile components of the product are denatured by heat or there are organic solvent residues in the product, which will affect the quality of the product

And at present, the deep processing of osmanthus fragrans as raw material mainly focuses on extracting the volatile components in osmanthus fragrans. The water-soluble components and fiber components in osmanthus fragrans are not extracted and utilized at the same time, which is a great waste of osmanthus fragrans resources
