A kind of preparation process of peony seed oil
Technical field
The present invention relates to oil tree peony processing technique field more particularly to a kind of preparation processes of peony seed oil.
Background technology
Edible oil consumption speedup is fast, but consumption figure deficiency.Grease is the indispensable nutriment of human body, with population in the world
Increase and living standards of the people improve, the consumption of global edible oil is to increase year by year.China is populous nation while is also edible
Oil consumption big country, the consumption figure of edible oil particularly edible vegetable oil rapid growth with the improvement of people ' s living standards.According to
Statistics, edible vegetable oil consumption is 13.5 kilograms per capita in China for many years, is then in recent years 17.3 kilograms, adds nearly 4 kilograms.
Even in this way, compared with European and American developed countries consume 45 kilograms in year per capita, there is larger gap.
Peony seed oil is green health edible oil, and nutritive value is high.Peony oil, which is also referred to as peony seed oil, to be carried from peony seeds
The high quality food oil taken, based on unrighted acid, oleic acid and linoleic acid content are up to more than 90%, than peanut oil, dish
The content of vegetable oil such as seed oil, soya-bean oil are all high, generally without harmful erucic acid, monounsaturated fatty acids in peony seed oil
Content is up to 90%, this is highest in all edible oil known today, and oil ratio content ratio is putative to be
Desired golden ratio in global edible oil.Unsaturated fatty acid content in high-quality peony seed oil is close to 90%, and fat
Acid balance pattern is close to needed by human body, component content:Oleic acid 75%~88%;Linoleic acid 3.5%~21%;Leukotrienes
0.3%~1.5%.Peony seed oil has certain curative effect for common cardiovascular diseases such as prevention and treatment hypertension, hyperlipidemias, right
Diabetic also has significant food therapy effect, and without any adverse reactions.Peony seed oil is not only edible or chemical industry,
The important raw and processed materials of medical aspect.Oleic acid and esters can be produced, can fixed oil be produced by hydrogenation and produce soap and vaseline etc.,
Also the industrial raw materials such as stearic acid and glycerine can be hydrolyzed into after deep hydrogenation, for making the injection of injection and modulating various
Ointment, pill etc..Peony seed oil treatment scald and the skin diseases such as burn and ringworm of the body, chronic eczema can be commonly used.China at present
Make injection and various ointment, the pill etc. that raw material successfully developed injection with peony seed oil, refine out natural advanced U.S.
Hold skin protection series cosmetics.
The method for preparing peony seed oil at present substantially takes traditional oil expression method, and this method protein denaturation is tight
Weight, peony seeds oil yield are low.
The content of the invention
The purpose of the present invention is overcoming the deficiencies of the prior art and provide a kind of preparation process of peony seed oil, with oily with male
Red seed is raw material, and in a manner that enzymatic isolation method and vaporizing extract process are combined, peony seed oil extraction is more complete, and oil yield is high, preparation
Peony seed oil aromatic flavour, pure and fresh, quality is good, no solvent residue, non-environmental-pollution.
The present invention adopts the following technical scheme that achieve these goals:
A kind of preparation process of peony seed oil, comprises the following steps:
(1) pre-process:Oil is taken to be screened with peony seeds, removing impurity, cryogenic freezing 20-30 days at a temperature of being first placed in -10 DEG C,
It stores 10-15 days at a temperature of 30-40 DEG C again, is then peeled off to obtain peony seeds benevolence with decorticator, peony seeds benevolence is in 60-80 DEG C of condition
It is lower holding 5-8 it is small when, it is spare;
(2) digest:The peony seeds benevolence of step (1) is crushed, adds in the basic protein of peony seeds benevolence weight 0.01-0.03%
Enzyme, at 40-50 DEG C, under conditions of pH is 8-9, when enzymolysis 2-4 is small;Add the pineapple of peony seeds benevolence weight 0.03-0.05%
Protease, at 50-60 DEG C, under conditions of pH is 6-8, when enzymolysis 1-2 is small;Add peony seeds benevolence weight 0.05-0.07%'s
Papain, at 70-75 DEG C, under conditions of pH is 6-7, when enzymolysis 1-2 is small, then enzyme deactivation 5-7 minutes at 95 DEG C;
(3) centrifuge:Enzymolysis solution after enzyme deactivation is taken to cool down, is centrifuged 15 minutes under 2000 revs/min, obtains free oil and breast
Change layer;
(4) strip:Emulsion layer is fitted into extraction kettle, the water of 3-5 times of its weight is added in, is stripped to obtain crude oil, be carried
Kettle pressure is taken as 20-30Mpa, temperature is 200-300 DEG C;
(5) alkali acid refines:The crude oil that step (4) is obtained heats, and hydroxide is added in when crude oil temperature reaches 60-70 DEG C
Sodium solution adds 60-80 DEG C of water degumming, is stirred continuously while water is added, when reprecipitation 6-7 is small;After alkali practices aquation
Crude oil adds in the activated decoloration of its weight 5-7%, and bleaching temperature is 100-110 DEG C,;After decoloration, filtering, the hair after filtering
Oil pours into deodorizing tank, is warming up to 150-170 DEG C, when distillation 3-5 is small, vacuumize 3-4 it is small when, vacuum degree 0.06-0.09MPa,
It finally cools down, obtains refined oil;
(6) refined oil that the free oil and step (5) that blend step (3) obtains obtain to get to refining peony seed oil.
Compared with the prior art, beneficial effects of the present invention are as follows:
(1) preparation process of peony seed oil of the invention, using oil peony seeds as raw material, using enzymatic isolation method and vaporizing extract process phase
With reference to mode, peony seed oil extraction is more complete, and oil yield is high, and the peony seed oil aromatic flavour of preparation, pure and fresh, quality is good, nothing
Dissolvent residual, non-environmental-pollution.
(2) after present invention stripping, it is combined by alkali refining with acid refining, effectively removes those and be not easy using absorption decoloring method
The pigment removed improves the quality of peony seed oil.
(3) during peony seeds of the invention pretreatment, low-temperature treatment is first carried out, the substance in peony seeds is protected under low-temperature condition
A period of time is held, non-oil substances in peony seeds is made to be converted into oily substance, amount in seed is improved, effectively improves peony seed oil
Oil yield.
