Description
Technical field
The present invention relates to edible fat production manufacture fields, the technique for espespecially preparing health-care corn oil using Nanofiltration-membrane technique.
Background technique
With the improvement of people ' s living standards and the accelerating rhythm of life, high-fat, high-energy diet is largely taken in, high in fat
The disease incidence of the cardiovascular diseases such as mass formed by blood stasis rises situation in obvious.World Health Organization WHO statistical report in 2017 shows,
In the world, cardiovascular disease death toll is 17,700,000, and the ratio for accounting for non-communicable diseases death toll is up to 44%.
And the cardiovascular disease of about one third both originates from high cholesterol.Wherein, the low-density lipoprotein in cholesterol can bring blood vessel
The aggregation of interior atherosclerotic plaque makes blood vessel become narrow, leads to the diseases such as coronary heart disease.More it is a risk that some patches
It is rather unstable, once rupture will block blood vessel the short time, lead to heart infarction or apoplexy, and it is very big to health hazard, or even directly
Threat to life.
Phytosterol is described as " key of life " by scientific circles, has highly important physiological function.Most important one
Function is to reach reduction by inhibiting modes and the approach such as the absorption of intestinal cholesterol, interference cholesterol transport, synthesis and secretion
The purpose of blood cholesterol levels.Vitamin E is effective natural, can remove the intracorporal oxyradical of people, protection T
The effects of lymphocyte, protection red blood cell, be the indispensable liposoluble vitamin of human body.
Cupreol in phytosterol and vitamin E, especially phytosterol, is prevalent in edible vegetable oil,
Wherein in corn oil phytosterol and content of vitamin E it is relatively high.But it is planted in conventional refining raw food oil technique at present
The loss late of object sterol and VE are higher, especially in deodorization and degumming tech, have Activities of Some Plants sterol and vitamin E by with each
The form of kind by-product loses, and leads to finished product --- and phytosterol and content of vitamin E in refined maize's oil are relatively
It is low.
Currently, commercially available high sterol content corn oil, usually using refined maize's oil as raw material, by adding phytosterol
Or the mode of phytosterin ester, reach high sterol content purpose.And used phytosterol or phytosterin ester, usually with
Generated by-product in vegetable oil refining industry --- it is extracted in deodorization distillate.Used phytosterol or phytosterol
Ester source not can determine that, cannot ensure its natural sex, and the safety of product corn oil cannot be protected.
Membrane separation technique is a kind of new and effective and accurate separation of success exploitation during the industrial development of 20th century
Technology.It is molten to two-component or multi-component Solute under the premise of stressed in addition using natural or synthetic polymeric membrane
Agent system is separated, purified or is enriched with.But the membrane technology of the overwhelming majority is the separation field applied to aqueous systems substance at present.
In vegetable oil production manufacture field, it there are no answered using the research of effective component in nanofiltration membrane separating plant oil at present
With report.There is patent report ceramic membrane filter oil-containing material, solid impurity therein is removed, referring to Chinese patent
CN104513704B, or utilize inorganic ceramic membrane for the degumming tech of vegetable oil crude oil and, the removing of colloid is because of phosphatide point
Son aggregates into the great substance of relative molecular weight and is separated, the non-nanofiltration grade of separation accuracy, referring to Chinese patent
101709245B。
Solvent resistant nanofiltration membrane is studied in the organic matter separation of non-aqueous system and application, is concentrated mainly on using organic film point
From the organic solvent in reaction system, such as the component separation of gasoline, light oil petroleum chemicals, referring to United States Patent (USP) US3956112,
US3370102, the separation of colloid and wax in grease system, referring to United States Patent (USP) US4787981 etc., edible oil is in n-hexane
Impurity is separated under equal solvent existence condition, referring to United States Patent (USP) US5310487.In above-mentioned a few class techniques, it is required to volatility
The participation of solvent.Production safety, environmental protection and in terms of there are potential hidden danger.
Summary of the invention
To solve the above problems, the present invention proposes a kind of technique that corn health-care oil is prepared using nanofiltration membrane beneficiation technologies,
Specific technical solution is as follows.
The natural nutrition factor prepares the new process of health-care oil during a kind of enriching plant is oily, comprises the following steps that：
（1）Corn oil raw material after refining is added in the head tank of nano filter membrance device, opens feed pump, corn oil is made to pass through nanofiltration
Film film core；
（2）Feed pressure is promoted, makes permeate by discharge hole for discharge, trapped fluid returns to head tank through circulation loop；
（3）Tapping flowrate is monitored, after tapping flowrate is stablized, starts to be received permeate by discharge port to get to the health care
Corn oil product.
Preferably, cupreol content is 5500 ppm, content of vitamin E 65 in corn oil raw material after the refining
ppm。
Preferably, corn oil raw material is the level-one finished product corn oil for meeting GB 19111 after the refining.
Preferably, cupreol content is 5900 ~ 6900 ppm in the health-care corn oil product, vitamin E contains
Amount is 79 ~ 105 ppm.
Preferably, the nanofiltration membrane is solvent resistant nanofiltration membrane.
Preferably, adjusting feed pump frequency converter in the step 2, feed pressure being promoted to 20 ~ 60bar, makes to penetrate
Liquid is by discharge hole for discharge.
Preferably, in the step 3, after tapping flowrate is stablized, start to receive permeate by discharge port, when receiving
Permeate volume when accounting for the 25% ~ 35% of corn oil raw material total volume, carry out secondary film for the permeate received as charging
Filtering, the secondary film filtering permeate received is the health-care corn oil product.
Preferably, tapping flowrate control is 0.1 L/ m in the step 32·h~0.13 L/ m2·h。
Preferably, rolling nanofiltration membrane component is packed into nano filter membrance device, connection charging, goes out circulation in the step 1
Expects pipe road connects circulating pump power device, turns on the electricity, then corn oil raw material after refining is packed into the charging of nano filter membrance device
In tank.
Preferably, corn oil raw material after refining is fitted into the head tank of nano filter membrance device, then in the step 1
Head tank is heated up and maintains material temperature to 50 ~ 55 DEG C.
The technical principle of nanofiltration UF membrane of the present invention is：
The pressure for applying up to 20-60 bar to raw material makes it through film.Due to the nano-pore structure of film, solvent passes through film, at
For " penetrating fluid ", and concentrate is rejected by the mixing organic solute that can also be applied in solvent.One or more solutes are through " seeping
Transparent liquid " passes through film, and other solutes are then trapped in " trapped fluid ".The stability and molecular selection of film are to determine the mistake
The key of journey.The selectivity of film is characterized by " molecular cut off ", range 150Da-900Da.
On this basis, the present invention under high pressure passes through corn oil raw material using the corn oil after refining as raw material
Nanofiltration membrane, the lesser cupreol of middle-molecular-weihydroxyethyl and vitamin E penetrate nanofiltration membrane with part corn oil, become permeate, should
The cupreol and content of vitamin E of permeate oil-containing are higher, and most corn oil does not penetrate film as trapped fluid.
