Description
Technical field
The present invention relates to the processing that technical field of food deep processing more particularly to a kind of thermostabilization rice bran meal extract rice bran oil
Method.
Background technique
Rice bran is important by-product during Rice producing, and the composition ratio of unsaturated fatty acid is close in rice bran oil
1:1.1, meets the optimal proportion of International Health Organization recommendation, and contains function factor, in prevention cardiovascular and cerebrovascular disease, improves
Immunity, reduction cholesterol and lipid aspects play huge potentiality.But the property of rice bran itself is unstable, after husk rice
Have activated lipase.Under fatty enzyme effect, grease contained by rice bran is easy to decomposite free fatty acid, cause it is rancid, after influencing
Phase processing refining, along with domestic production scope of the enterprise is little, it is difficult to concentrate the deep processing research for carrying out rice bran, only minimal amount
Enterprise extract rice bran oil from rice bran, for traditional extracting method there are at high cost, post-processing steps are cumbersome, lead to rice bran oil
It is at high cost, it occupies in market less than catbird seat, so country's a big chunk rice bran is still used as the domestic animals such as pig, sheep, ox at present
The feed of poultry, added value is low, causes the great wasting of resources, therefore according to the extraction situation of nowadays rice bran oil, provides one kind
The rice bran oil that high quality is extracted from rice bran, the processing method for reducing later period refining are the emphasis of byproduct processing industry research.
Summary of the invention
The object of the invention is to remedy the disadvantages of known techniques, provides a kind of thermostabilization rice bran meal and extracts rice bran oil
Processing method.
The present invention is achieved by the following technical solutions:
A kind of processing method that thermostabilization rice bran meal extracts rice bran oil, comprising the following specific steps
(1) raw material is sieved and removes the sundries and metal of blending, be fitted into plastic containers after dust removal of pneumatic separation and be placed in radio frequency heating dress
In setting, simultaneously constant temperature keeps 4-7min to control heating temperature, and taking-up is cooled to room temperature；
(2) step (1) treated rice bran is mixed with deionized water, then adjusts the pH value of feed liquid with the hydrochloric acid solution of 2mol/L
For 4-5, according to 0.23%(w/w) ratio adds complex enzyme thereto, and the enzyme digestion reaction 180-200min at 55 DEG C adjusts pH value
For 9 enzyme deactivations, reaction was completed, and mixture is then transferred to jet cooking device high temperature processing a period of time, then mixed by what is obtained
Conjunction liquid, which is placed in a centrifuge, is centrifuged 10min with the revolving speed of 4000r/min, and it is spare that supernatant is made；
(3) isopropanol solvent of 5 times of amounts will be added in the supernatant being prepared in step (2), the ultrasound extraction 1- at 60 DEG C
2h, then mixture is filtered by vacuum, precipitated impurities are discarded, oily mixture is placed in rotary evaporator at 85 DEG C and evaporates removing
Rice bran oil can be obtained in isopropanol solvent.
The processing method that a kind of thermostabilization rice bran meal extracts rice bran oil, radio frequency heating dress as described in step (1)
The power set is 6KW, wavelength 11m, frequency 27MHz.
The processing method that a kind of thermostabilization rice bran meal extracts rice bran oil, control heating temperature as described in step (1)
Temperature in degree is 120 DEG C.
The processing method that a kind of thermostabilization rice bran meal extracts rice bran oil, rice bran described in step (2) and go from
The material-water ratio of sub- water is 1:5.
The processing method that a kind of thermostabilization rice bran meal extracts rice bran oil, complex enzyme described in step (2) are fibre
Tie up plain enzyme and neutral proteinase, mass ratio 7:3.
The processing method that a kind of thermostabilization rice bran meal extracts rice bran oil, jet cooking device described in step (2)
High temperature processing a period of time, refers to and handle 90s at 150 DEG C.
The invention has the advantages that the present invention, which handles rice bran meal by radio frequency heating, can penetrate significant inside rice bran reduce
The vigor of lipase causes lipolysis slack-off, and the stabilisation performance of rice bran meal is good, be able to extend period of storage without
It is rancid, and the time is short during processing, does not influence the structure of nutriment in rice bran meal, and treated, and rice bran meal passes through again
Enzyme digestion reaction is closed, oil yield is improved, and is good by the oil quality that enzyme digestion reaction obtains, acid value is relatively low, after being conducive to
Continuous processing refines, and further removes sundries using jet cooking technology after enzyme digestion reaction and is easier to the nutritional ingredient in rice bran
It is extracted, increases the albumen and other nutritive element contents of rice bran oil, the processing method of rice bran oil provided by the invention is simple, just
In operation, obtained rice bran oil purity is high, the later period, fine purification operations were few, remain to the greatest extent nutrition in rice bran at
Point, efficiently quickly, can large-scale plant production, application prospect is good, is worthy to be popularized.
