Description
Technical field
The present invention relates to ginger essential oil extractive technique field, in particular to a kind of extracting method of ginger essential oil.
Background technique
Ginger, be Zingiber, zingiber herbaceos perennial fresh rhizome, in China as a kind of traditional medicine food two
With crop, there is stomach invigorating, promoting blood circulation, removing toxic substances, preventing or arresting vomiting, sweating, sterilization, anticancer and other effects.The complex chemical composition of ginger can be divided into
Volatile oil, gingerol and Diphenylheptane three categories, in addition also containing there are many amino acid, vitamin and iron, copper, manganese, zinc, chromium,
The various trace elements such as nickel, cobalt, germanium and several functions composition.Ginger essential oil is the condensed matter extracted from ginger,
It is the main deep processed product of current ginger.Ginger essential oil has dissipation hemostasis, controls wound, improve oily skin, go stomach swollen
Gas, and improve internal moisture, such as resolving sputum brings down a fever, hypocatharsis, makes the effect of body warmer.Currently, extracting ginger extract from ginger
The conventional method of oil mainly has steam distillation, solvent extraction method and supercritical CO2Extraction.
But in the prior art, the chemistry as contained by the ginger oil of solvent extraction method acquisition has very at selected solvent
Important Relations, and the ginger essential oil of extract by solvents vulnerable to residual solvent pollution and can precipitate discoloration, therefore solvent method is answered
With being subject to certain restrictions.Supercritical CO2Although extraction no solvent residue, because cost is too high, answering in the industrial production
With also less.And the biggish essential oil of volatility in the mainly ginger that common steam distillation obtains, and certain volatility compared with
Small ingredient, because of its unique molecular structure, it is difficult to be steamed with water vapour, and distillation process in this common distillating method
High temperature can make the ingredient, smell, flavor of ginger oil change.It is low to the recovery rate of ginger currently on the market, loss of effective components
It is more, fail the numerous effects for giving full play to ginger.
Summary of the invention
For the low problem of ginger recovery rate existing in the prior art, the present invention provides a kind of extractions of ginger essential oil
Method.
The technical solution of the present invention is as follows: a kind of extracting method of ginger essential oil, includes the following steps:
Step 1: preparing ginger powder: taking ginger, washes away surface impurity with clear water, it is omnipotent to be put into high speed after chip drying
3~5min is crushed in pulverizer, is crossed 80~100 meshes, is obtained ginger powder；
Step 2: ionic liquid assistance enzymolysis: ionic liquid N-methyl morpholine oxide is added in citrate buffer solution, matches
The ionic liquid buffer system that volume fraction is 15%~35% is made, by cellulase, hemicellulase, pectase and step
Ginger powder made from rapid one is added into ionic liquid buffer system and is digested, obtain enzymatic hydrolysis mixture, ginger powder and
The ratio of ionic liquid buffer system is 1:15-30g/mL；
Step 3: ultrasound on extracting: enzymatic hydrolysis mixture made from step 2 is carried out in 85~95 DEG C of water-bath
Destroy the enzyme treatment after being cooled to room temperature, is added distilled water and carries out ultrasound on extracting, separation obtains ginger essential oil A and residue；
Step 4: residue water mentions: the residue that step 3 obtains is added to progress water in 60~85 DEG C of hot water and is mentioned,
Centrifugation, obtains Aqueous extracts and residue；
Step 5: residue filters pressing: residue made from step 4 is put into filter press and is squeezed, pressed liquor is obtained；
Step 6: molecular distillation is extracted: the pressed liquor that the Aqueous extracts B and step 5 that step 4 is obtained are obtained carries out molecule
Distillation is extracted, and obtains ginger essential oil B, the ginger essential oil A and ginger essential oil B of acquisition are the ginger extract extracted from ginger powder
Oil.
Further, the PH of citrate buffer solution is 4.9~5.5 in step 2.
Further, step 2 cellulase, hemicellulase and pectase mass ratio are 1:1:1 or 2:1:1.
Further, the enzyme activity ratio of step 2 cellulase, hemicellulase and pectase is 3000~4500U/
g。
Further, the volumetric usage of distilled water is 10~13 times for digesting mixture, supersonic frequency 30 in step 3
~40KHz, time are 40~60min.
Further, the number that water mentions in step 4 is 3~4 times, and centrifugation time is 10~20min.
Further, vacuum degree is 0.1~1pa in the alembic tank of molecular distillation in step 6.
The invention has the beneficial effects that:
The present invention extracts ginger essential oil using ionic liquid assistance enzymolysis and ultrasound on extracting technique, and to ginger essential oil
The further water of residue after extraction mentions, and the residue after recycling filter press to mention water carries out filters pressing, and water is finally proposed acquisition
The pressed liquor that Aqueous extracts and residue filters pressing obtain is all made of the extracting mode of molecular distillation, and each step is cooperateed with mutually, mentioned significantly
The high recovery rate of ginger.Concrete reason is: cellulase, hemicellulase and pectase act on ginger cell, can make
Cellulose degradation in its cell wall and cytoplasm causes cell wall and cytoplasm structure partial is loose, expansion, reduces thin
The resistance that the mass transfers such as cell wall and cytoplasm barrier spreads volatile component out of cell to Extraction medium；And the ion added
Liquid N- methyl morpholine oxide can not only improve the thermal stability of cellulase, hemicellulase and pectase, keep it not volatile
It is living, and the generation for digesting and reducing enzymatic side reaction can be improved as reaction medium；Ultrasound on extracting is by ultrasound
The effects of cavitation of vibration, crushing, stirring, ginger cell is destroyed, penetrates into solvent wherein, the effective component of ginger is accelerated to enter
Solvent strengthens mass transfer；Using water mention by ginger residue Aqueous extracts and residue separate；Filters pressing is to utilize a kind of special mistake
Filter medium applies certain pressure to ginger residue, so that liquid dialysis therein comes out, further obtains in ginger residue
Pressed liquor；Last binding molecule distillating method realizes Aqueous extracts and squeezing using the difference of each component evaporation rate in feed liquid
The further extraction separation of effective component, to substantially increase the recovery rate of ginger essential oil, is avoided and is mentioned using tradition in liquid
Take mode distill obtain ginger essential oil after by residue abandon and bring effective components of ginger loss mostly with recovery rate it is low
Problem.
