Abstract
The invention relates to a method for extracting and refining paeonia rockii seed oil. The method comprises the following steps: collecting seeds, unshelling, baking and frying, carrying out screw press, filtering, deacidifying, degumming, drying, decoloring, deodorizing in vacuum, adding an antioxidant and filling. After solid impurities and residues obtained by the screw press are broken up, ethylacetate is added, then refluxing extraction is carried out, and a solvent is recovered so as to obtain the paeonia rockii seed oil for cosmetics. A two-step method is used for extracting the paeoniarockii seed oil, wherein in the first step: primary pressed oil used for eating is obtained by physical pressing, and the produced paeonia rockii seed oil has higher oil recovery rate and no residualsolvents and can be securely eaten; in the second step, the ethyl acetate is adopted for extraction, and ingredients for antioxidation, inflammation resistance, sun block, and the like in the paeoniarockii seed oil can be extracted and used for producing the cosmetics. The invention not only improves the oil recovery rate of paeonia rockii seeds, but also ensures that the effective ingredients in the paeonia rockii seeds are sufficiently utilized.
Description
Technical field
The high efficiency extraction that the present invention relates to tree peony deep process technology field, especially paeonia rockii seed oil is utilized technology, is the method for a kind of extraction and refining paeonia rockii seed oil specifically.
Background technology
Gansu is the important place of origin of Chinese tree peony, and the Gansu Paeonia papaveracea is as the second largest product population of Chinese tree peony, with its cold-resistant drought-enduring, plant is tall and big, solid power is strong etc., and characteristics are extensively cultivated in the various places, Gansu.For a long time, the tree peony of various places cultivation is mainly sold to view and admire with nursery stock, the development and use of tree peony deep processed product but seem serious and lag behind, the production added value is very low, do not form industrial chain, particularly paeonia rockii seed has only and is used for breeding on a small quantity, and annual a large amount of seed falls in the ground in vain, the wasting of resources and serious.The Paeonia suffruticosa seed oleaginousness is nearly 30%, contains multiple unsaturated fatty acidss such as oleic acid, linolic acid, linolenic acid in the peony seed oil, and especially linolenic acid content reaches more than 40%.Linolenic acid is to increasing intelligence; strengthening immunity; vision protection, blood fat reducing brings high blood pressure down; lowering blood glucose; suppress hemorrhagic disease of brain and thrombotic diseases, suppress the generation and the transfer of cancer, prevention myocardial infarction and cerebral infarction; the Ammonium Glycyrrhizate disease, preventing inflammation and reducing human aging etc. has obvious effect.Generally lack alpha-linolenic acid in the population of China meals at present, half of the not enough world health organisation recommendations amount of daily intaking amount, this also is to cause one of China's cardiovascular disorder, diabetes, near-sighted reason occurred frequently.China's medical circle and the expert of nutrition educational circles appeal the special alpha-linolenic acid that replenishes of national legislation one after another.Linolenic acid content is all very low in our the daily food, and it is linseed oil or perilla seed that the product that linolenic acid content in the market is high is mainly produced material, but since these two kinds crop yield is low, distribution range is narrow, turnout is little, the cost height, fetch long price is difficult to satisfy great demand.Traditional oil expression technology oil yield is not high, can only obtain the fatty acid glycerine ester moiety in the tree peony seed.As a kind of oil plant of preciousness, the tree peony seed adopts traditional oil expression technology certainly will cause the waste of resource.If adopt modern solvent-extraction process, have certain dissolvent residual again, not only bad for eater's health, also can cause certain trouble to refining.
Summary of the invention
The present invention will solve traditional tree peony seed to adopt the not high problem of traditional oil expression technology oil yield, and the processing method of a kind of extraction and refining paeonia rockii seed oil is provided, and the head oil expression employing physical squeezing that is used to eat, and no solvent residue can relievedly eat; The seed oil that two procedures extract can fully leach the effective constituent in the tree peony seed again, can be used for the processing of other peony seed oil products, has improved the utilization ratio of peony seed oil greatly.
The present invention solves its technical problem by following technical proposals:
The method of a kind of extraction and refining paeonia rockii seed oil may further comprise the steps:
A. seed collection:
Pluck full ripe Paeonia papaveracea fruit, dry in the air 6-8 in dry ventilation and after Follicle radish fruit is all ftractureed, beat fruit, the tree peony seed is come off naturally;
B. shell, bake stir-fry:
Collect the tree peony seed that nature comes off, the roasting frying pan is sent in mechanical dejacketing, be warming up to gradually 120 ℃ evenly roasting fry, constantly stir-frying to 80% tree peony seed benevolence fries;
C. screw press and filtration:
The tree peony seed benevolence that roasting is fried is evenly sent into expeller continuously, and peony seed oil is extruded out under pressure, and the rotating speed of screw shaft is at 8-10r/min, and the crude oil that squeezes out is stand-by with oil filter filtration solid impurities and residues, gets tree peony seed crude oil;
D. depickling:
Use 11% NaOH solution alkali-refining deacidification, adding alkali number is theoretical alkali charge and excess alkali quantity sum, alkali lye divides three addings, the alkali refining initial temperature is 40 ℃, stirring velocity is 60r/min when adding alkali, treat to reduce stirring velocity when oily soap separates, and the oil temperature that raises is to 60 ℃, centrifugal treating under 5000r/min gets depickling oil then;
E. come unstuck:
Depickling oil is preheated to 60 ℃, the phosphoric acid that adds depickling oil mass 85%, the oil of phosphoric acid heavily is 0.2%, 60 ℃ of hot water of adding 3% behind the thorough mixing, begin to stir with the 55r/min rotating speed, when the big phosphatide particle of sesame appears in the oil meter face, slow down stirring velocity, when the cohesion of phosphatide particle is obvious separate stage, stop to stir, utilize whizzer to remove phosphatide and get degummed oil to 15r/min;
F. dry, decolouring:
Control vacuum tightness is more than 93.3kPa, and oily temperature is heated to 90 ℃, and white fog disappears to the pot, progressively puts into oil in the time of stirring and weigh 3% carclazyte in oil, decolour 30 minutes, decolours oily temperature to be cooled to below 50 ℃ after finishing, filter bleached oil;
G. vacuum deodorization:
Vacuum tightness is heated to 170-180 ℃ with bleached oil more than 101.2kPa, kept 3 hours, stops heating, treats that oily temperature is cooled to that vacuum breaker gets deodorised oil below 50 ℃.
H. add antioxidant:
Get the Tert. Butyl Hydroquinone of deodorization oil mass 0.01%, be made into 5～10% solution, add in the g step gained deodorization peony seed oil, continue to stir can 30 minutes with deodorization peony seed oil dissolving;
After the described c step, stand-by solid impurities and residues was broken up, adds 4 times and measure ethyl acetate, 75 ℃ of following backflow lixiviates 3 hours; Decompression and solvent recovery gets the used for cosmetic peony seed oil.
The present invention adopts two-step approach to extract peony seed oil, and the first step adopts physical squeezing, and the peony seed oil oil yield of production is higher, no solvent residue, edibility; Second step was adopted the ethyl acetate lixiviate, anti-oxidant, the anti-inflammatory in the peony seed oil, the abundant lixiviate of composition such as sun-proof can be come out, and was used for cosmetics production.Not only improved the oil yield of tree peony seed, and the effective constituent in the tree peony seed is fully used.
