Abstract
The invention belongs to the field of a peony oil extracting technology, and in particular relates to a method for extracting peony oil by water. The peony oil is obtained by placing the peony petals into an extraction kettle after being ground, adding 1-5 folds by weight of water, controlling the pressure of the extraction kettle to 5-30Mpa, temperature to 100-300 DEG C and extraction time to 5-120 min, separating to obtain an extracting solution, cooling the extracting solution to 100 DEG C, performing oil water separation, and collecting the oily matters. A high-temperature high-pressure extraction process provided by the invention is capable of very quickly obtaining the peony oil, and also has the advantages of being free of an organic solvent, clearer process, more friendly environment, faster extracting speed, higher efficiency, simpler technology, and lower equipment and operation cost.
Description
Technical field
The invention belongs to tree peony caul-fat extractive technique field, particularly a kind of method with water extraction Tree Peony flower oil.
Background technology
Tree peony is the Ranunculaceae Paeonia, and machaka is distributed widely in Henan, Shandong, Anhui, Shaanxi, Sichuan, zhejiang and other places, especially with Luoyang, the plantation of two places, Heze at most.
The large-scale U.S. of Tree Peony flower, elegant and poised, the light uniqueness of the fragrance of a flower are traditional famous flowers of China, and the beginning contains in Tang, and " unsurpassed " Song Yu is thriving and prosperous, lucky rich and honour symbol, are described as king aromatic, in spending.
Contain micro-natural flavor material and terpenes, hydrocarbon compound in the Tree Peony flower, as geraniol, Geraniol, phantol etc., health-care effects such as calmness, anti-inflammatory, endocrine regulation are arranged.But because content is very little and molecular weight is little, volatile, be difficult for, so expensive.The peony essential oil of Xiao Shouing mostly is composite or the chemosynthesis gained in the market, and life-time service is unfavorable to skin.
Few to the extraction research of tree peony caul-fat at present, the finding extracting method has distillation method (extraction of peony essential oil from water vapour by distillation and the application CN200710189719.4 in perfuming cigarette thereof), petroleum ether extraction method (peony extraction extracted from petroleum ether and the application CN200710189718.X in perfuming cigarette thereof) and supercritical CO
2Extraction process (a kind of supercritical CO
2The method CN200810049972.4 of abstracting tree peony volatile oil; A kind of supercritical extraction method of peony essential oil and application CN201110302946.X thereof) etc.What extraction efficiency was the highest is supercritical CO
2Extraction process.But these extracting method complex steps, extraction efficiency is not high, is not suitable for big production requirement.
Summary of the invention
The object of the present invention is to provide a kind of method with water extraction Tree Peony flower oil, this method required time is short, the friendly environmental protection of solvent, and process is simple.
For achieving the above object, the technical scheme taked of the present invention is as follows:
A kind of method with water extraction Tree Peony flower oil: extract in the still packing into after the peony petal pulverizing, add water 1-5 times of weight, it is that 5-30Mpa, temperature are 100-300 ℃ that still pressure is extracted in control, extraction time is 5-120 minute, separate and obtain extracting solution, it is cooled to below 100 ℃, and oily water separation is collected oily matter and is namely got the tree peony caul-fat.
Preferably, it is 100-200 ℃ that the still temperature is extracted in control, and extraction time is 5-60 minute.
Further preferably, described peony petal is half-open to peony petal in full bloom.
Again further preferably, peony petal is crushed to particle diameter at 20 ~ 60 orders.
Still more preferably, will pulverize again after peony petal cleaning, the drying.
Water extraction of the present invention is operated and can be realized in the conventional High Temperature High Pressure extraction in this area equipment, need not to purchase in addition special equipment.
Water is the extraction solvent of an environmental sound.Under the normal temperature and pressure, the polarity of water is very big, can dissolve polar organic compound well, but then very little to Semi-polarity and nonpolar organic compound solubleness.Along with the rising of temperature, the polarity of water can reduce, to the dissolving power increase of Semi-polarity and nonpolar organic matter.
Under the pressure of appropriateness, when water was heated to 100-374 ℃ sub-critical temperature, the polarity of liquid water can vary with temperature and change, and more is similar to organic solvent, and the dissolving power of Semi-polarity and nonpolar organic matter is strengthened greatly.As being 250 ℃ when temperature, during pressure l0MPa, polarity and the methyl alcohol of liquid water are suitable.
The boiling point of Vegetable oil lipoprotein is generally 170-300 ℃, adopts High Temperature High Pressure water extraction method of the present invention can make the grease stripping complete, and extraction yield can be up to more than 1%.Compare with distillation and extraction method, yield is higher; Compare with the organic solvent extraction method, not with an organic solvent, avoided the organic solvent residual of pollution and extract; Compare with supercritical carbon dioxide extraction, do not use the carbonic acid gas that can produce Greenhouse effect, and the efficient height, extraction time is also short.
High Temperature High Pressure water extraction of the present invention can very rapidly obtain the tree peony caul-fat, has without the need for machine solvent, process cleaning, environmental friendliness, advantage such as extraction rate is fast, efficient is high, technology is simple, equipment and running cost are lower, is embodied in:
(1) process is simple: present method mainly is divided into extraction and separated for two steps, water is pumped in the extraction still of the peony petal that pulverizing is housed, and certain hour is extracted in the back of heating up, and after the high temperature extraction liquid cooling but being discharged, oily water separation gets final product again;
(2) environmental protection: present method adopts water as solvent, just makes the water that extracts in the still keep subcritical state, and process makes the green process that grease extracts becomes a cleaner production more close to the pressure kettle poach food that uses in the family.
(3) extraction time is short: because the characteristic of water under High Temperature High Pressure, the stripping property of grease in the Tree Peony flower is had good promoter action, extraction time usually at several minutes to dozens of minutes;
(4) the grease stripping is complete: the intensification gradually of water (natural heating process) can be played gradient elution and similarly act on, and extracts fully, and yield is at 0.8-1.3%.
5) industrial application value: technology is simple, can mass-producing extract grease, has industrial application value.
