Abstract
The present invention provides a kind of method that use superelevation platen press extracts oenothera seed oil.Its inventive step is as follows：First oenothera seed is pre-processed, selected oenothera seed is dried after 24h at 85 DEG C, crush, sieving obtains oenothera seed powder, then appropriate oenothera seed powder is chosen to add in vacuum packaging bag, and the ether for adding a certain amount of solid-liquid ratio adjusts certain temperature and pressure, after pressurize for a period of time as Extraction solvent, it is drawn off carrying out suction filtration, finally extracts oenothera seed oil.The present invention carries out carrying oil by superelevation platen press; operating condition needed for this process is gentle; oenothera seed oil is avoided to go bad at high temperature; preferably protect the unrighted acid in oil; farthest retain the fine quality of the trace nutrient and product in raw material; and oil extracting rate is higher, appointed condition requires relatively low.
Description
Technical field
The present invention relates to a kind of method that use superelevation platen press extracts oenothera seed oil.
Background technology
The seed oil content of oenothera biennis is about 21%, and the oil that evening primrose seed is squeezed out is exactly evening primrose oil.Evening primrose oil
In contain 7% linoleic acid, 11% oleic acid, 6% palm fibre acid, a variety of unrighted acids such as 7%-14% gamma-Linolenic acids, wherein γ-
Leukotrienes is the indispensable necessary aliphatic acid of human body, relevant with many physiological activities, with very strong bioactivity.Oenothera biennis
Oil has the effect such as obvious anti-inflammatory, anti-oxidant, antithrombotic, reducing blood lipid, hypoglycemic, fat-reducing, to diabetes, hyperlipidemia, artery
Atherosis, coronary heart disease etc. have a significant curative effect, and before being had a wide range of applications in the field such as medical treatment, health care and food industry
Scape.
Research shows, using a variety of methods for extracting evening primrose oil outside Current Domestic, there is its respective defect, such as grasps
Making easy milling process and prepressing extraction method, oil extracting rate is relatively low under normal conditions, and the higher direct leaching of oil extracting rate and super
Critical CO2Method, the oil solvent residual that the former proposes is higher, and the latter is higher to technological operation and equipment requirement.
The present invention is the method that evening primrose oil is extracted using superelevation platen press, i.e., first selected oenothera seed is dried at 85 DEG C
After dry 24h, crush, sieving (60 mesh) obtains oenothera seed powder.Raw material after crushing is carried out at ultra high pressure treatment and suction filtration
Reason, makes oil plant eucaryotic cell structure thoroughly destroy and improves oil yield, the liquefied mixture obtained after suction filtration, rotated evaporation, dries,
Obtain oenothera seed oil.Operating condition needed for this process is gentle, entirely puies forward oily process under room temperature environment, substantially reduces
Energy consumption, using the method for ultra high pressure extraction oil, it is low comprising impurity content, and energy consumption is low, efficiency high, easy to operate, environmental protection,
The advantages of having wide range of applications.
The content of the invention
Oil yield is low in method of the present invention in order to solve existing extraction oenothera seed oil, and impurity is more, technological operation is numerous and diverse,
The problems such as equipment requirement is higher, and propose a kind of method that use superelevation platen press extracts oenothera seed oil.Superelevation platen press extracts the moon
See that the method for seed oil is realized by following steps：First, oenothera seed is pre-processed；2nd, oenothera seed powder is surpassed
High pressure and suction filtration processing；3rd, oenothera seed oil is extracted；
The present invention beneficial point be：The present invention carries out carrying oil by superelevation platen press, and operating condition needed for this process is gentle, keeps away
Exempt from oenothera seed oil at high temperature to go bad, preferably protect the unrighted acid in oil, farthest retain in raw material
Trace nutrient and product fine quality, and oil extracting rate is higher, requires relatively low to appointed condition.
Embodiment
Embodiment one：A kind of method for extracting oenothera seed oil with superelevation platen press is realized by following steps：
