Description
Technical field
The present invention relates to the manufacture craft of biological medicine and food processing technology field, particularly a kind of high quality tea oil.
Background technology
Oil tea is the oil crops that China distinctive woody oleiferous plants ，Ye Shi China greatly develops.The comprehensive utilization value of oil tea is very high, contain the biologically active substances such as abundant unsaturated fatty acids, monounsaturated fatty acids, VITAMIN e, squalene, tea-polyphenol, wherein monounsaturated fatty acids can improve blood resistance of oxidation, reduce cholesterol, prevent the generation of cardiovascular and cerebrovascular diseases, can also reduce the appearance probability of the disease causing because of Metabolic disorder such as insulin resistance diabetes, be diabetes, cardio-cerebral vascular disease patient and three high crowds' first-selected edible oil; Unsaturated fatty acids has " not polyester " characteristic, and not only self is in internal organ and subcutaneous deposition, and can stop fatty deposits, can avoid getting fat, and medically, tea oil, for assisting therapy obesity, is the health-care edible oil of a kind of " consuming oil, it is fat not to be afraid of "; VITAMIN e is a kind of liposoluble vitamin, claims again tocopherol, can promote sex hormone secretion, man's motility of sperm is increased, make woman's female hormone Enrichment, improve Fertility, also can be used for preventing and treating the aspects such as male infertility, burn, capillary hemorrhage, climacteric syndrome, beauty treatment.Recently also find that VITAMIN e can suppress the lipid peroxidation reaction in eye lens, make slightly vasodilation of end, improve blood circulation, pre-myopia prevention occurs and development; Unsaturated fatty acids wherein, medicinal or edible value is very high, has the brain development and the cranial nerve function that improve tire baby, strengthens brain cell informational function, promotes human brain normal development; Strengthen tire baby's eyesight; Promote tire baby's function and body to grow, particularly to hypogenetic fetus and premature infant, can promote their physiogeny to reach normal level, the bodily form in pregnant and lying-in women's postpartum is also had to the physiological functions such as material impact simultaneously; Squalene is a kind of lipid unsaponifiables, having and improve superoxide-dismutase (SOD) activity in body, enhancing body immunological competence, the sexual function of improving, anti-ageing, antifatigue, the different physiological roles such as antitumor, is a kind of avirulent biologically active substance of preventing and curing diseases and acting on that has; Tea-polyphenol is the general name of polyphenols in tea oil, comprise flavanol compound, anthocyanin class, flavonoid, flavonols and phenolic acids etc., have and reduce cholesterol, anti-ageing, radioprotective, removing human free radical, cancer cells is had to inhibiting all-natural anti-oxidant.
In prior art, the processing of tea oil adopts the traditional method in rural area mostly, and its technological process is: parch, pulverize, step on cake, squeezing, filtration, become traditional " soil " tea oil.This kind of tea oil, owing to not passing through refining, contains more objectionable impurities, and also can produce thick smoke when the cooking, has both affected environment, harmful again.In the last few years, more domestic Oils and fats enterprises and units concerned are studied the refinery practice of tea oil, develop the tea oil refining technique of some applicable suitability for industrialized production, as Chinese patent " refining method for camellia oil that nutrition content is high " (number of patent application is 200910307817.2), this invention causes the problems such as the too much loss of Camellia oil nutrition for prior art excess Temperature, the refining method for camellia oil that a kind of nutrition content is high is provided, and its key step comprises: under normal temperature, produce crude oil; Add warm water, then by settlement separate method, remove lower floor's impurity and water; Add sodium hydroxide solution, then by settlement separate method, remove water and soap stock; Heating tea seed crude oil to 80 ℃～90 ℃, adds 1～3 part of atlapulgite, under-0.1MPa～-0.095MPa, is cooled to 68 ℃～72 ℃ through 15～20 minutes, then with cotton, filters; 140～150 ℃ of temperature, vacuum tightness 200Pa to 260Pa, obtains deodorization Camellia oil after distillation; After deodorization Camellia oil Slow cooling, static pressure filters, and obtains refining Camellia oil.Chinese patent " preparation method of pure camellia oil " (number of patent application is 200910307817.2) and for example, adopt pure physical cold squeezing mode, filter removal impurity and obtain pure Camellia oil, and need not any chemical assistant in oil and fat refining, adopt pure physical method, the activeconstituents that has effectively retained Camellia oil, oil colours is more shallow, in oil and fat refining without depickling, decolouring, the courses of processing such as deodorization just can obtain meeting national GB11765-2003 pressed tea seed oil standard, retained the natural flavour mountaineous and fruital of Camellia oil, there is technique simple, cost is low, the feature that oil yield is high.
Summary of the invention
The object of the present invention is to provide a kind of activity that can retain target component in tea oil, can reject useless or harmful impurity again, and the tea oil manufacture craft that consumes energy low, environmental pollution is little, with short production cycle.
For solving the problems of the technologies described above, the technical solution used in the present invention is the manufacture craft of a kind of high quality tea oil of invention, and its technical process is as follows:
A, crude oil preparation: take fresh tea seed as raw material, through low-temperature cold pressing, process, make crude oil, standby;
The de-soap of b, alkali refining: standby crude oil is placed in alkali refining device, first measures the acid value of crude oil, then heat and stirs 1-3h to 50-60 ℃， while heating, then to add concentration be the alkali aqueous solution of 30-40%, precipitate 10-14h, filtering soap stock, obtains alkali refining crude oil, standby; During alkali refining, the add-on T of alkali presses formula and calculates: T=7.1 * 310
-4* crude oil weight * acid value;
C, washing are come unstuck: standby alkali refining crude oil temperature is slowly risen to 80-90 ℃, and by 0.2% of alkali refining crude oil weight, adding concentration is the salt brine solution of 40-60%, and limit edged stirs, then, and constant temperature precipitation 1-2h, again filtering soap stock in the time of 60-80 ℃; 80 ℃ of above hot water that add again 2 times of weight of alkali refining crude oil, stir, precipitation 2-3h, and filtering colloid and the aqueous solution, and repeat this step 2-3 time, and obtain washing tea oil, standby;
D, carclazyte decolouring: standby washing tea oil is heated to 90-100 ℃， and stirred while heating, then add the carclazyte that accounts for washing tea oil weight 8-20%, stir, churning time is 0.5-1h, and filtration, removes carclazyte, obtains decolouring tea oil, standby;
E, high temperature deodorization: when standby decolouring tea oil is heated to 90-100 ℃, open vacuum pump, while heating again to 140-160 ℃, open steam spray, while continuing again to heat to 240-250 ℃, be incubated 0.5-1.5h, then the normal temperature cold water that adds 2-3 times of weight of decolouring tea oil, be cooled to normal temperature, repeat above-mentioned steps 2-3 time, obtain high quality tea oil.
Described alkali aqueous solution is NaOH, Ca (OH)
