Through low-temperature drying, squeezing by a double helix squeezer as well as the filtration technology by standing, the preparation method disclosed by the invention can avoid overheating and excessive chemical treatment to the oil, avoid residues of harmful substances generated during high-temperature processing, and avoid residues of acid, alkali and heavy metals due to addition of chemical addition agents; in addition, the technology disclosed by the invention can retain the pure natural quality of the tea-seed oil, and as much as possible retains physiological characteristic substances in the tea oil, such as vitamin E, gamma-linolenic acid and other beneficial components.
Description
Technical field
The present invention relates to a kind of duplex low temperature pressing making method of tea oil.
Background technology
Tea oil is because of its golden yellow color or pale yellow, and quality is pure, clear, and smell delicate fragrance, good taste, and do not contain harmful materials such as erucic acid, SUV, flavacin, can be used as the solvent of vein input with oil or medicine.Contain specific physiologically active substance tea-polyphenol and camellianin in the tea oil, can effectively improve the rising of cardiovascular and cerebrovascular diseases, reducing cholesterol and fasting plasma glucose, supression triglyceride, anticancer is also had tangible effect.Therefore, tea oil is that Chinese Government advocates the woody edible vegetable oil of promoting of pure natural, also is the first-elected health care vegetable edible oil of international food and agricultural organization.
But in existing tea oil production technique, need the cating quality standard that steaming is fried through high temperature, multiple refinery practice just can reach tea-seed oil; Not only influenced the nutritive value of tea-seed oil; And it is residual in the process that the high temperature steaming is fried, to have objectionable impurities, can add chemicaladditives in the multiple refining process, and it is also residual to cause acid, alkali, heavy metal etc. to have; The nutritive substance loss of tea-seed oil is big, and oil yield is low.
Summary of the invention
The purpose of this invention is to provide a kind of duplex low temperature pressing making method of tea oil, it can overcome the weak point of prior art.
Technological solution of the present invention is following
A kind of duplex low temperature pressing making method of tea oil may further comprise the steps:
A) oven drying at low temperature; Use plate dryer and vacuum fan to dry the tea seed after the screening, bake out temperature is 45-55 ℃, and drying time is 55-65min, the tea seed water ratio 6-10% after the oven dry;
B) separation of peeling off; Adopt the vane type decorticator to peel off the tea seed after the above-mentioned oven dry, remove tea seed shell, obtain clean tea seed kernel;
C) low temperature pressing; Utilize squeezing machine that the tea seed kernel that obtains is squeezed, obtain camellia oil;
D) leave standstill filtration; The tea-seed oil that obtains is left standstill, precipitates, make oil, water AUTOMATIC ZONING, behind the removal moisture content, carry out twice coarse filtration removal impurity, obtain thick tea oil through vertical blade filter and plate type pressure filter;
E) winterization is handled; The thick tea oil temperature that obtains was kept 48 hours in 3-5 ℃ environment; Carry out winterization and handle, make the higher ester matter of zero pour and wax at low temperatures crystallization separate out, filter through the hydraulic plate pulling diaphragm filter press is smart again; Remove impurity, ester matter, wax in the oil, obtain smart tea oil;
F) finished product; The smart tea oil that obtains after again winterization being handled polishes filtration with the cloth bag filter that is added with filter paper, and water ratio is reduced to below 1%, obtains finished product tea oil.
Among the said step a, said bake out temperature is 50-55 ℃, and drying time is 55-60min, the tea seed water ratio 8% after the oven dry.
In the said step b), said squeezing machine is a double spiral squeezer.
In the said step d), the time of leaving standstill is 72 hours.
Winterization in institute's step e) is handled and in refrigerator, is carried out.
The finished product tea oil that institute's step f) obtains, monounsaturated fatty acids content>=75% by weight percentage, linolic acid>=20%, linolenic acid content≤2%, lipid acid≤3%.
Beneficial effect of the present invention is:
Through low temperature pressing with leave standstill filtration process and can avoid the superheated of oil plant and too much chemical treatment; It is residual to produce objectionable impurities when avoiding high temperature process; Also avoid because of adding acid, alkali, the heavy-metal residual that chemicaladditives causes; Technology of the present invention can keep the pure natural quality of tea-seed oil, has kept the physiological property material in the tea oil again as much as possible, like beneficiating ingredients such as vitamin E, gamma-linolenic acids.
