Description
Technical field
The invention belongs to tobacco aromatics using field, be specifically related to the preparation method of a kind of spice, further relate to
Obtained spice and purposes.
Background technology
Vegetal natural perfume be from the flower of fragrant plant, grass, leaf, branch, dry, stem, root, skin,
Really, the fragrant body goods that extract in the position such as seed, resin or balsam, great majority are oily or cream
Shape, minority is resin or semisolid.Form according to them and preparation method, commonly referred to quintessence oil, tincture
Agent, extractum, absolute oil, face cream or oleoresin, such as Flos Rosae Rugosae quintessence oil, red date tincture, Radix Glycyrrhizae extractum,
White orchid face cream and ginger oil resin.
In the preparation method of vegetal natural perfume, steam distillation is common method.Water is steamed
Vapour is passed through in the container filling plant material, and volatile ingredient with steam distillation out, is produced
The component of natural perfume material is the volatility grease of armaticity, commonly referred to collectively as quintessence oil.Water vapour steams
In evaporating, water mainly plays three kinds of effects, i.e. water and dissipates effect, hydrolysis and thermodynamic activity, water
Mechanism is simply summarized as follows, and raw material surface wet water molecule is inside the cell tissue of raw material
Infiltration water displacement quintessence oil or oligodynamical quintessence oil diffuse to form being total to of quintessence oil and water in water
Boiling thing quintessence oil steams condensation oil-water separation quintessence oil with water vapour simultaneously.Except in boiling water
Outside the plant material that main note composition easily dissolves, hydrolyzes or decomposes, most fragrant plants
Quintessence oil is prepared with steam distillation.Steam distillation has three kinds of principal modes: water distillation,
Distilling above water and steam distillation, the equipment of steam distillation mainly has distillating still, condenser and profit
Separator three part.There is many deficiencies in existing steam distillation technique, such as, with extraction
Extract the oily timesharing in watery thing, the organic extractant of a large amount of contaminative need to be used；Multiple steaming can destroy
