Abstract
The present invention discloses a method for refining woodfrog egg oil, which is characterized in that the acid value of woodfrog egg oil is reduced by an ion exchange resin method. The present invention comprises the steps: firstly, dissolving woodfrog egg oil by lower alcohol; secondly, processing the obtained lower alcohol solution of woodfrog egg oil into an OH-shaped anion exchange resin column, and processing effluent into an H-shaped cation exchange column; finally, recovering the lower alcohol to obtain refined woodfrog egg oil. The method can relatively lower the acid value of woodfrog egg oil, and has the advantages of no oil loss in refining, high purity, low content of impurity, simple operation, large daily processing capability and easy industrial production.
Description
The present invention discloses a kind of process for purification of woodfrog egg oil, relates to fatty greasy refinement treatment technology.
Rana temporaria chensinensis David is famous and precious animal drugs, and its traditional drugs is the uterine tube of female individuals with part, i.e. Oviductus Ranae, and its ovum then goes out of use except being used for edible major part on a small quantity as byproduct.Studies show that, contain more lipid composition in the wood frog ovum, adopt organic solvents such as ethanol, ethyl acetate, hexane to leach or use CO
2Supercritical extraction method can extract woodfrog egg oil, and extraction yield is between 8～25%, and the material that obtains is the red-brown oily liquids.But the woodfrog egg oil that adopts aforesaid method to extract contains a large amount of free fatty acidies, and acid value is very high, can reach 40～80.The acid value of lipids height not only easily causes spoiled by rancid oil or fatly, also human body is exerted an adverse impact.Traditional alkali refining method can be used for the depickling of woodfrog egg oil, but owing to the layering difficulty causes greasy a large amount of loss, causes the woodfrog egg oil waste, and can't adopt.
The present invention discloses a kind of process for purification of woodfrog egg oil, and purpose is intended to reduce oil loss, simple to operate, obtains the refining woodfrog egg oil that acid value is low, the high impurity of purity is few.
Technical conceive of the present invention is as follows: utilize the acid value in the ion-exchange-resin process reduction woodfrog egg oil.At first, woodfrog egg oil is dissolved with lower alcohol, the dissolving ratio is 1: 2～15 weight parts, with the low-alcohol solution of the woodfrog egg oil that obtains by being processed into the anion-exchange resin column of OH type, effluent liquid is after the cation exchange resin column that is processed into the H type, with the lower alcohol Separation and Recovery, get the purified woodfrog egg oil.Described lower alcohol comprises that carbonatoms is 1～4 monohydroxy-alcohol or dibasic alcohol, as ethanol, methyl alcohol, propyl alcohol, propyl carbinol, and preferred alcohol solution.
When the ethanolic soln of woodfrog egg oil passes through anionite-exchange resin, free-fat acid group in the solution and the OH in the resin
-Exchange, be switched on the resin, and OH
-Then dissolve in the solution, effluent liquid is alkalescence, and this solution is followed by Zeo-karb (anticipating into the H type), at this moment, and positively charged ion in the solution and the H on the resin
+Ion exchanges, and positively charged ion is exchanged up, H
+Ion is exchanged gets off to enter solution, with the OH in the solution
-Ion generation neutralization reaction generates water, thereby removes the free fatty acids in the woodfrog egg oil, reduces its acid value, is made with extra care.The TREATMENT OF ION EXCHANGE RESINS method is conventional treatment process, with ethanol the water in the post is ejected after just adorning post, make and be full of ethanol in the resin column, resin anion(R.A) absorption is handled the back water with 5% acidic alcohol, 5% aqueous hydrochloric acid of heat respectively after saturated and is dashed to neutral in addition, uses the aqueous solution regeneration OH type of 5% NaOH at last.
The present invention compared with prior art has the following advantages: it is more thorough to reduce acid value, no grease loss in the treating process, and the purity height, foreign matter content is low, and is simple to operate, and daily handling ability is big, but suitability for industrialized production.
Further describe the present invention below in conjunction with embodiment.
