Abstract
The invention discloses a method for producing pepper seed oil, mainly comprising the steps of crushing pepper seeds, frying seeds, expelling, dewaxing, extracting low-polarity organic solvent, processing extraction liquid on the upper and lower layers, wherein the upper layer is recycled by recovering organic solvent; the material obtained from concentration is free fatty acid; the lower-layer liquid is grease with low acid value, drying, decolouring and filtering at low temperature by a regular refining process to obtain the qualified oil product with the acid value within the range of national standard. In the invention, the pepper seed skin and kernel are expelled together, the crude oil contains a great amount of alpha-linolenic acid in the kernel and volatile oil in the skin, the crude oil is firstly dewaxed and then a great amount of free fatty acid is extracted with the organic solvent, then alkaline refining is performed, the yield of the product is improved, the additional value of the secondary product of wax and the free fatty acid is high, and the loss of volatile oil and oxidization of alpha-linolenic acid are reduced via the low-temperature refining process. The produced pepper seed oil contains above 30 percent of the alpha-linolenic acid and has intense spicy smell. The invention ensures that the pepper seed is comprehensively processed and utilized.
Description
Technical field
The present invention relates to the preparing technical field of edible oil, particularly a kind of production method of Fructus Zanthoxyli oil.
Background technology
Perennial shrub of Zanthoxylum Rutaceae or dungarunga are one of eight traditional big food flavourings of China.Semen Pericarpium Zanthoxyli is the byproduct during the Chinese prickly ash pericarp is produced, and it is reported that China's annual output has more than 130 ten thousand tons approximately.Semen Pericarpium Zanthoxyli contains the crude fat more than 20%, and wherein alpha-linolenic acid content contains a large amount of volatile essential oils more than 30% in the pepper seed skin, and Fructus Zanthoxyli oil is a kind of being of high nutritive value and characteristic flavor oil.But,, make the difficulty of its processing and utilization bigger because the acid number of Fructus Zanthoxyli oil is high and the wax content height.The existing processing technology of Fructus Zanthoxyli oil mainly contains following several: (1) is broken with benevolence with pepper seed skin, disposable leaching crude oil, and refining becomes edible oil again; (2) earlier pepper seed skin is carried out the solvent lixiviate, seed skin oil is used for technical oils, again Semen Pericarpium Zanthoxyli benevolence is carried out lixiviate, and refining makes edible oil; (3) earlier with the Semen Pericarpium Zanthoxyli decortication, then pepper seed skin and benevolence are adopted lixiviation process and oil extraction by pressing respectively; (4) with after the Semen Pericarpium Zanthoxyli fragmentation, use supercritical CO
2Extract edible oil.The subject matter that above-mentioned working method exists: the one, use supercritical CO
2The Fructus Zanthoxyli oil that extraction equipment is produced, quality is good but facility investment is big, the production cost height; The 2nd, produce Fructus Zanthoxyli oil with the solvent extraction method, large-scale leaching plant exists that facility investment is big, the problem of starving, and small-sized leaching plant exists precipitation to be difficult to problem up to standard; The 3rd, Semen Pericarpium Zanthoxyli decortication effect is undesirable, and the decortication cost is also than higher; The 4th, adopt traditional alkali-refining deacidification method, the refining consumption is too big, and product yield is low.
Summary of the invention
At the deficiency that above-mentioned prior art exists, the invention provides the production method of the Fructus Zanthoxyli oil that a kind of technology is simple, production cost is low, comprehensive utilization is effective, added value is high.
A kind of production method of Fructus Zanthoxyli oil comprises following processing step:
(1) after being cleaned, Semen Pericarpium Zanthoxyli is broken into 6 orders-60 purpose particle;
(2) with ground grains under 70 ℃ of-130 ℃ of conditions, fried 10 minutes-30 minutes;
(3) the Semen Pericarpium Zanthoxyli particle of frying squeeze the Semen Pericarpium Zanthoxyli crude oil;
(4) crude oil is carried out the routine dewaxing, crude oil and wax must dewax;
(5) in the dewaxing crude oil, add the weakly polar organic solvent of 1 to 3 times of crude oil volume, stirred 20-60 minute under the room temperature, left standstill then 30-60 minute, obtain stratified liquid, wherein supernatant liquid is the mixed solution of organic solvent and free fatty acids, and lower floor's liquid is the lower grease of acid value;
(6) supernatant liquid is taken out and separation, the organic solvent recycling, enriched material is a free fatty acids; The grease of lower floor's liquid gets processed oil through refining again.
The production method of described Fructus Zanthoxyli oil is characterized in that, preferred 10 orders-20 of described Semen Pericarpium Zanthoxyli particle size after cracking order.
The production method of described Fructus Zanthoxyli oil is characterized in that, 100 ℃-110 ℃ of described Semen Pericarpium Zanthoxyli frying condition optimizations, frying 15 minutes-20 minutes.
The production method of described Fructus Zanthoxyli oil is characterized in that, described weakly polar organic solvent comprises methyl alcohol, ethanol, acetone, propyl alcohol or similar solvent.
The production method of described Fructus Zanthoxyli oil, it is characterized in that described weakly polar organic solvent preferred volume concentration is the ethanol of 70%-95%, and crude oil and described alcoholic acid volume ratio are 1: 2-2.5, preferred 20 ℃-30 ℃ of extraction temperature, churning time are 30-40 minute, time of repose 40-60 minute.
The production method of described Fructus Zanthoxyli oil is characterized in that, described extraction solvent ethanol preferred volume concentration is the ethanol of 90%-95%.
The production method of described Fructus Zanthoxyli oil is characterized in that, described oil and fat refining adopts vacuum drying process, and the vacuum drying process temperature is 60 ℃-80 ℃; Vacuum tightness-0.07MPa--0.085Mpa; 30 minutes-90 minutes time of drying.
The production method of described Fructus Zanthoxyli oil is characterized in that described vacuum drying process condition optimization temperature is 75 ℃-80 ℃; Vacuum tightness-0.075MPa--0.08Mpa; Be 40 minutes-60 minutes time of drying.
The present invention compared with prior art, its advantage is that (1) extracts oil pepper seed skin and benevolence jointly, not only complete processing is simple, and has kept a large amount of ethereal oils that contain in a large amount of alpha-linolenic acids that contain in the benevolence and the skin in the crude oil; (2) with crude oil dewaxing in advance, the crude oil that dewaxes on the one hand helps the deacidifying process in later stage, has reduced tooling cost, and the added value of the wax that parses on the other hand is higher; (3) depickling is carried out in two steps, earlier with alcohol extraction go out to dewax most of free fatty acidies in the crude oil, make the acid number of crude oil be controlled at lower level on the one hand, being beneficial to economical and practical alkali-refining deacidification carries out, the refining techniques of existing Fructus Zanthoxyli oil has reduced the refining consumption, improve product yield, on the other hand the added value height of the byproduct soap stock that spissated free fatty acids obtains than alkali refining behind the alcohol extraction; (4) except that the stir-fry seed carried out about 100 ℃, the post-production process all was controlled at below 80 ℃ and finishes, and has reduced the loss of ethereal oil and the oxidation of alpha-linolenic acid.The Fructus Zanthoxyli oil of producing with this method contains 30% above alpha-linolenic acid, has intense spicy smell, be the edible flavouring oil that is rich in alpha-linolenic acid that has characteristic, its byproduct wax and free fatty acids can be used as the raw material of chemical industry or biofuel, the comprehensive processing and utilization that the present invention has carried out Semen Pericarpium Zanthoxyli preferably.
