Abstract
The invention discloses a kind of methods of Subcritical Water Extraction peony seeds sterol, using subcritical abstraction kettle as reaction vessel in the present invention, water is extractant, peony seeds powder is extracted to extract peony seeds sterol, the invention avoids the food-safety problems that dissolvent residual in organic solvent extraction is brought, and due to water suitable pressure and at a temperature of, surface tension, viscosity and polarity can decline, peony seeds sterol can be made to be dissolved out from peony seeds cell to greatest extent, significantly improve the dissolution rate of peony seeds sterol.
Description
Technical field
The present invention relates to effective ingredients in plant extractive techniques, and in particular to a kind of side of Subcritical Water Extraction peony seeds sterol
Method.
Background technology
Tree peony (Paeonia suffruticosa Andr.) belongs to Ranunculaceae Paeonia shrub, western part Qinling Mountains native to China
It is perennial machaka with Daba Mountain one with mountain area.Peony seeds also contain sterol, white other than being rich in grease and albumen
The functional components such as veratryl alcohol.A kind of additive of the sterol as functional food has anti-oxidant, reduction cholesterol, inhibits swollen
Tumor and immunoregulatory effect.In the prior art, the extraction of peony seeds sterol mainly uses ethyl alcohol or methanol solution to carry out, cost
It is higher, it be easy to cause environmental pollution.
Invention content
It is an object of the invention to be to overcome deficiency in the prior art, a kind of Subcritical Water Extraction peony seeds steroid is provided
The method of alcohol, the technical scheme is that：
A kind of method of Subcritical Water Extraction peony seeds sterol, which is characterized in that include the following steps：
(1) pretreatment of raw material：Peony seeds are first removed into the impurity such as weed seed, soil block, stone, then peony seeds are carried out
Heat treatment finally crushes treated peony seeds, and peony seeds powder is crossed 60 mesh sieve；
(2) Subcritical Water Extraction：By peony seeds powder and water according to mass volume ratio 1:5-1:The ratio of 20g/mL is mixed
It closes, is put into subcritical abstraction kettle after stirring evenly and carry out subcritical fluid extraction, extractant is water, extracting pressure 2-
20MPa, extraction temperature are 100-180 DEG C, extraction time 20-60min；
(3) it detaches：It is after extraction that extract liquor is cooling, centrifuge, peony seeds sterol be obtained by filtration.
Further technical solution, step (2) Subcritical water extraction preferred parameter are：The quality volume of peony seeds and water
Than being 1:15g/mL, extracting pressure 12MPa, 140 DEG C of extraction temperature, extraction time 30min.
Beneficial effects of the present invention：
1, the present invention makes full use of the advantages of Subcritical Water Extraction, using Subcritical Water Extraction peony seeds sterol, reaches letter
The purpose for changing peony seeds sterol extraction process, reducing pollution, improving peony seeds sterol quality.
2, the present invention carries out peony seeds sterol extraction using Subcritical Water Extraction technology, and extractant is water, is avoided organic
The food-safety problem that dissolvent residual is brought in solvent extraction method.
3, subcritical water refers under a certain pressure, heating the water to 100 DEG C or more, 374 DEG C of height below of critical-temperature
Temperature, water body stills remain in liquid condition, but its Wuli-Shili-Renli system approach has bigger difference with the water under normal temperature and pressure.The present invention
By in subcritical abstraction kettle, keep water suitable pressure and at a temperature of, since the surface tension, viscosity and polarity of water are equal
It can decline, property can be such that sterol is dissolved out from peony seeds cell to greatest extent closer to organic solvent, significantly improve male
The dissolution rate of red seed sterol.
4, this method has low for equipment requirements, simple for process, and extraction time is short, low energy consumption, pollution-free, it is easy to accomplish work
Industry.
