The invention discloses the preparation method of a kind of healthy tea oil, prepared Oleum Camelliae use low temperature oil expression, alkali refining, wash, decolour, deodorize, secondary decolourization, freezing processing and extraction carry out integrated treatment, have filtered off most unwanted contributions and harmful components.Oleum Camelliae prepared by the present invention is possibly together with multiple high active substance such as substantial amounts of monounsaturated fatty acid, unsaturated fatty acid, vitamin E, tea polyphenols and flavone, with health role, is particularly suitable for the healthy tea oil that anemia of pregnant woman, child and person in middle and old age eat.
Description
Technical field
The present invention relates to a kind of edible camellia oil, particularly to the preparation method of a kind of healthy tea oil.
Background technology
Oleum Camelliae is the distinctive woody oleiferous plants of China, the oil crop that Ye Shi China greatly develops.The comprehensive utilization valency of Oleum Camelliae
It is worth the highest, containing biological activitys such as abundant unsaturated fatty acid, monounsaturated fatty acid, vitamin E, Squalene, tea polyphenols
Material, particularly unsaturated fatty acid, medicinal or edible value is the highest, has brain development and the cranial nerve merit improving child
Can, strengthen brain cell informational function, promote brain normal development.Monounsaturated fatty acid can improve blood antioxidant ability, fall
Low cholesterol, prevents the generation of cardiovascular and cerebrovascular disease, moreover it is possible to reduce such as insulin resistance diabetes etc because of Metabolic disorder
And the appearance probability of the disease caused.Vitamin E is a kind of fatsoluble vitamin, also known as tocopherol, can promote sex hormones secretion,
Improve fertility, it may also be used for prevent and treat the sides such as male infertility, burn, capillary hemorrhage, climacteric syndrome, beauty treatment
Face；Squalene is a kind of lipid non-saponifiable matter, has the internal superoxide dismutase of raising (SOD) activity, enhancing human body immunity
Ability, improve the different physiological roles such as sexual function, defying age, resisting fatigue, antitumor, be a kind of avirulent have prevent and cure diseases
The bioactive substance of effect；Tea polyphenols is the general name of polyphenols in Oleum Camelliae, including flavanol compound, anthocyanin class, flavone
Class, flavonols and phenolic acids etc., have reduction cholesterol, defying age, radioprotective, removing human free radical, have cancerous cell
The all-natural anti-oxidant of inhibitory action.
At present, although the Oleum Camelliae product of commercial type is more, such as Camellia oil, refine Oleum Camelliae, cold pressing Oleum Camelliae etc. and add
Mediation Oleum Camelliae added with other various edible vegetable oils etc., these oils and fatss, in the course of processing, mostly use conventional method, because of
And, some nutritional labelings in Oleum Camelliae are destroyed.
CN103725408A discloses the processing technique of a kind of Camellia oil, including: (1) selects materials, remove impurity and be dried；(2) broken
Broken, obtain camellia seed kernels, dry；(3) cooling, adds fresh bran coat or tea-seed, low temperature pressing；(4) heating, adds Fructus Citri Limoniae
Acid, adds water, and stirring stands, except water remove impurity；(5) add activated carbon or kieselguhr under vacuum, filter；(6) stirring, cooling, quiet
Put growing the grain, filter.The Camellia that the present invention uses oil content to be 28%-30% is raw material, makes through scientific and reasonable technique
Camellia oil is non-transgenic product, and maximum journey remains the intrinsic local flavor of Camellia oil, fragrance and nutrient substance.But it decolours and takes off certainly
Effect is not ideal enough.CN102504942A discloses the preparation technology of a kind high quality tea oil, uses low-temperature cold pressing, alkali refining to take off
Soap, washing degumming, hargil decolouring and high temperature deodorizing technology, prepare high quality tea oil；Then, the property that each active substance is different is utilized
Matter and functional characteristics, use kinds of processes,；Have and can retain the activity of target component in Oleum Camelliae, can reject again useless or have
The impurity of evil, and consume energy low, environmental pollution is little, the feature such as with short production cycle, both can process suitable popular edible Oleum Camelliae, also
Can process the edible camellia oil with health maintenance effect, can process again the healthy tea oil that suitable middle-aged and elderly people is edible, it is suitable also can to process
The healthy tea oil that anemia of pregnant woman and juvenile eat.But this preparation method is relative complex, Oleum Camelliae utilization rate is the highest, and Oleum Camelliae cost is bigger.Literary composition
Offer CN103232888A and disclose the extraction process of a kind of black tea oil, it is characterised in that comprise the following steps: (1) sorts；(2) broken
Broken；(3) fermentation；(4) dry；(5) stir-fry is steamed；(6) squeezing；(7) filter；(8) alkali refining；(9) washing；(10) deodorize；(11) freezing.
The red Oleum Camelliae that the extraction process of the black tea oil of this invention is produced, in tea-seed, oiliness tea polyphenols material fills with oxidase
Producing oxidation polymerization effect under point action by contact, when fermentation, the enzymatic synthesis of microorganism secretion vitamin B group, particularly ties up life
Element B12, B12 are the vitamin that animal and plant self all cannot synthesize, and the quality such as color making tea-seed oil is the highest,
There is prevention senile dementia, the cholesterol in human serum can be reduced, improve the health care merit such as gastrointestinal function, prophylaxis of tumours
Effect.Prepared by this technique is a kind of black tea oil, and Milling Efficiencty is the highest, and the suitable crowd's scope used is little.
Summary of the invention
It is an object of the invention to overcome that oil yield present in prior art is low, deodorize and undesirable the lacking of decolorizing effect
Point, it is provided that healthy tea oil that a kind of person in middle and old age juvenile eats and preparation method thereof.
Technical scheme is as follows:
The preparation method of a kind of healthy tea oil, comprises the following steps:

With squeezing effect.
The present invention uses low temperature alkali refining method, preferably protects the nutritional labeling in Oleum Camelliae not broken while removing Fructus Gleditsia
Bad.
The present invention uses sodium chloride and acetic acid mixed aqueous solution to wash, can be effectively by the impurity in Oleum Camelliae, harmful
Composition and unnecessary moisture wash out.
The present invention uses compound adsorbent, and prepared Oleum Camelliae clear, without bitter taste.
Oleum Camelliae prepared by the present invention use low temperature oil expression, alkali refining, wash, decolour, deodorize, secondary decolourization, freezing processing
Carrying out integrated treatment with extraction step, decolouring, deodorising effect are good, and have filtered off unwanted contributions and harmful components, prepared tea
Breakdown of oil is transparent, have tea smell, without bitter taste.Oleum Camelliae prepared by the present invention contains substantial amounts of monounsaturated fatty acid, insatiable hunger
With multiple high active substance such as fatty acid, vitamin E, tea polyphenols and flavone, there is healthy opsonic action, human chitinase can be improved
Activity, improve metabolic rate, improve body constitution and increase body immunity, be particularly suitable for what anemia of pregnant woman, child and person in middle and old age ate
Healthy tea oil.
