Abstract
The invention discloses a technology for refining rice bran oil from rice bran. The technology for refining the rice bran oil from the rice bran comprises the steps of raw material pretreatment, degumming, high-voltage pulsed electric field treatment, deacidification, secondary degumming, adsorption and decolouration, deodorization, obtainment of a refined oil product and the like. Compared with the prior art, by means of the technology for refining the rice bran oil from the rice bran, the purpose of fully separating grease from free fatty acid is achieved, the acid value of the rice bran oil ranges from 2.0 mgKOH/g to 3.5 mgKOH/g and is far lower than the acid value, ranging from 10 mgKOH/g to 30 mgKOH/g, of ordinary rice bran crude oil, the loss problem of oryzanol in the alkali refining and deacidification process can be avoided, and the quality and the nutrition value of the refined oil product are improved.
Description
Technical field
The invention belongs to Rice pollard oil processing technique field, be specifically related to a kind of technique of refined rice bran oil from rice bran.
Background technology
Rice pollard oil is the deep processed product of rice bran, and it contains abundant linolic acid, oleic acid, vitamin-E, thiaminogen, sterol, has very high healthy nutritive value.At present, the production method of Rice pollard oil is mainly based on milling process, lixiviation process and supercritical fluid extraction.But it is high that pressed oil has acid number, lixiviation process has the problems such as dissolvent residual, and two kinds of method gained Rice bran crude oil all need through depickling, come unstuck, dewax, to decolour and the step such as deodorization just can reach use standard, complex procedures; And supercritical fluid extraction though the two yield is high comparatively above, need working pressure to reach 35 MPas in extraction process, and the loss of thiaminogen is large.Therefore find a kind of thiaminogen loss little, acid value is low and the new method of refining that product yield is high is particularly important.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the object of this invention is to provide a kind of technique of refined rice bran oil from rice bran.
Technical scheme of the present invention is: a kind of technique of refined rice bran oil from rice bran, comprises following concrete steps:
(1) pre-treatment of raw material; Get Rice bran crude oil to filter, removing solid impurity;
(2) come unstuck: crude oil is entered aquation pot, add the phosphoric acid of 3 ‰ of quality of crude oil, stir 20min, in order to remove non-hydratable phospholipid, be then warming up to 70 DEG C, add 75-80 DEG C of hot water of 5% of quality of crude oil, stir 40min, precipitation 9h carries out hydration degum;
(3) pulsed electric field process: the Rice bran crude oil after coming unstuck is carried out pulsed electric field process, strength of electric field is 15-30kv/cm, and the burst length is 70-90us, and pulse-repetition is 180-300Hz;
(4) depickling: with the extraction agent of extraction free fatty acids phase and the extraction agent of oil and grease extracting phase, Rice bran crude oil after 25-35 DEG C of extraction is come unstuck 3-5 time, at every turn add in the Rice bran crude oil after 1g comes unstuck the ratio that 1-1.5ml extracts the extraction agent of free fatty acids phase and the extraction agent of 1-2ml oil and grease extracting phase and add the extraction agent of extraction free fatty acids phase and the extraction agent of oil and grease extracting phase, each extraction time is 15-25min, then separatory distillation removes extraction agent and obtains deacidification rice bran oil;
(5) again come unstuck: Rice oil at 60 DEG C once, alkali lye is added by 40kg/t oil, being warming up to 85 DEG C goes whizzer to take off soap separation, then oil temperature rises to 90 DEG C, add 95 DEG C of hot water of oil mass 15%, entering washing whizzer to wash, is carry out dry degummed oil under the vacuum state of 4-10kPa at pressure after washing;
(6) adsorption bleaching, deodorization: carry out adsorption bleaching, deodorization process according to a conventional method;
(7) acquisition of processed oil: the Rice oil through decolouring, deodorization process carries out crystallization 22h, after growing the grain 8h, carry out degreasing at 0-3 DEG C through Winterization filter and obtain degreasing oil, degreasing oil adds the thiaminogen of 2-2.5g/kg in mass ratio, the sterol of 1-2g/kg, the vitamin-E of 0.5g/kg, obtains nutritious processed oil.
Compared with prior art; advantage of the present invention is: adopt pulsed electric field to assist two-phase to extract depickling; reach the object being fully separated grease and free fatty acids, the Rice pollard oil acid number of gained is 2.0-3.5mgKOH/g, well below the acid number 10-30mgKOH/g of usual Rice bran crude oil; the loss problem to thiaminogen in alkali-refining deacidification process can be avoided; improve quality and the nutritive value of product oil, in addition, the present invention is simple to operate; be easy to control, the large-scale production of suitable Rice pollard oil.
