Abstract
The invention discloses a preparation method for organic black rice bran oil. The preparation method comprises five steps: cleaning and screening, preparing oil mixture, steaming, purification and deodorization. The preparation method for the organic black rice bran oil reduces the loss of neutral oil and thus effectively increases the refining rate. Besides, since saponin and washing wastewater are greatly reduced, the cost for treating saponin and washing wastewater is greatly reduced, and meanwhile high-purity mixed fatty acid can be obtained. Compared with a base-dissolving acidification method, a solvent extraction method technology greatly increases the yield of refined rice bran oil, limited raw materials are fully utilized, and meanwhile the refining yield of rice bran oil is increased by 5%. The purity of the finished product can be more than 98% to reach the standard of quality products. In oil refining, a physical refining deacidification technology and a solvent method extraction oryzanol production technology are successfully combined for the first time, no alkali refining oil residue is produced, no lipoid or black fatty acid is discharged in oryzanol extraction, and the environment pollution caused by production is basically prevented.
Description
Technical field
The invention belongs to edible oil preparation method technical field, be specifically related to a kind of organic black rice Rice pollard oil preparation method.
Background technology
Black rice has long cultivation history and advantageous advantages for development in Yang County, black rice quality enjoys great prestige inside and outside the province, is cited as the organic black rice production base of the whole province's high-quality and the advanced county of economic forest based on the industry of organic black rice.Black rice rice bran main component is rice cortex, rice embryo and cracking rice on a small quantity, the nutritive ingredient of enrichment cereal 78%, its oleaginousness can reach 18-26%, the main raw material that the black rice Rice pollard oil therefrom extracted has as senior mixed oil, function type health care, has good curative effect effect to human body cardiovascular and cerebrovascular diseases, maladjusted nervous system.Rice pollard oil is the grease extracted in gained rice bran when being processed into rice from brown rice, and Rice pollard oil contains the nutritions such as abundant thiaminogen, β-Sitosterol, vitamin-E, squalene.As everyone knows, thiaminogen, vitamin-E are natural antioxidants; Thiaminogen, Sitosterol can stop human body to the absorption of cholesterol; Vitamin-E, squalene energy enhancing body immunizing power and anti-ageing; Oleic acid, linolic acid are the necessary lipid acid of human body, and in Rice pollard oil, oleic acid, linolic acid ratio are rationally, easily digested, but domestic market are all substantially rice bran level Four oil.There is the problems such as color and luster is dark, wax content is high, mouthfeel is poor, affect commercial value, external Rice pollard oil selling price is higher, as 2.65 dollars/kilogram, the U.S..
Summary of the invention
The object of the present invention is to provide a kind of preparation method of organic black rice Rice pollard oil, solve existing Rice pollard oil color and luster dark, wax content is high, the problem of mouthfeel difference, and cost is lower.
The technical solution adopted in the present invention is: organic black rice Rice pollard oil preparation method, comprises the steps:
The first step, cleaning is sieved
Get fresh black rice rice bran, after process that fresh rice bran is sieved, then put into and steam stir-fry machine and carry out steamings and fry, acquisition rice bran coarse fodder;
Second step, produces mixing oil
The rice bran coarse fodder that the first step is obtained is put into leacher and carry out leaching process, obtain mixing oil;
3rd step, steams
The mixing oil that second step obtains is carried out secondary respectively steam, the temperature that first time steams is 90 ~ 100 DEG C, and steaming time is 3 ~ 5 hours, the temperature that second time steams is 110 ~ 120 DEG C, time is 2 ~ 4 hours, carries out stripping again after second time steams to mixing oil, obtains rice bran crude oil;
4th step, purifies
The rice bran crude oil that 3rd step obtains is carried out successively first time filtration, hydration degum, alkali refining, washing, decolouring, second time filtration and winterisation process, obtain high-purity Rice pollard oil;
5th step, deodorization
High-purity Rice pollard oil that 4th step obtains is put into deodorizer and carries out deodorization process, finally prepare organic black rice Rice pollard oil.
Feature of the present invention is also,
When in 4th step, first time filters, the order number of filter screen used is 200 orders, and when second time is filtered, the order number of filter screen used is 400 orders.
The invention has the beneficial effects as follows: the preparation method of organic black rice Rice pollard oil of the present invention decreases the loss of neutral oil, thus effectively improves refining yield; In addition, because greatly reducing Chinese honey locust and washes amount, thus the expense greatly reducing process Chinese honey locust and dispose of sewage, highly purified mixed fatty acid can be obtained simultaneously.Solvent extration technique makes refined rice bran oil go out rate to be greatly improved than alkali-soluble acid analysis method, and limited raw material is utilized fully, and the refining yield of Rice pollard oil improves more than 5% simultaneously.Finished product purity can reach more than 98%, reaches high-quality product standard.The molten filtration of slubbing alkali refining, alkali and Methanol Recovery three operations are had to discharge the waste materials such as oil foot, lipoid and black acid in alkali-soluble acid analysis method production technique, these waste materials are processed into useful lipid acid also to need to consume a large amount of mineral acid, alkali, larger environmental pollution can be caused.And physical refining deacidification technique and solvent extraction thiaminogen production technique have been carried out successful combination first by solvent extration production technique in oil refining, do not have alkali refining oil foot to produce, thiaminogen extraction does not have lipoid and black acid to discharge yet, and substantially relieves production pollution on the environment.
