Description
Technical field
The invention belongs to plant oil extract fields, and in particular to a kind of side that peanut oil is extracted using surfactant water phase
Method.
Background technique
As the improvement of people's living standards, the consumption figure of edible oil and fat is high, and the main source of edible oil and fat
It is vegetable fat.The extracting method of existing vegetable fat mostly uses organic solvent extraction.Common grease extractant is industry
Hexane and 6# solvent naphtha (mixture of short hydrocarbon).
However, it has proved that the volatilization that grease extracts organic solvent in production is one of important sources of atmosphere pollution.Ring
Packing pressure is increasingly enhanced, so that innovation grease extractive technique becomes inevitable.In addition there is dissolvent residual in product oil, it is strong to human body
Kang Wuyi.
Grease water phase abstraction technique is a kind of green, environmentally friendly, safety technique, is expected to substitution grease organic solvent leaching in the future
Technique out, it is also increasingly deep to its research.
Grease water phase extraction process is still faced with three big technical bottlenecks at present: first is that grease extraction efficiency is low, second is that emulsification is tight
Weight, edible vegetable oil yield is low, third is that waste water handling problem.Wherein influence the main problem of grease water phase extraction process industrial applications
It is the low problem of grease extraction efficiency, so that the economy of technique is not high.For this purpose, actively improving grease water phase extracting process, mention
High grease extraction efficiency becomes the important prerequisite that grease water phase extraction process realizes industrial applications.
Can the critical issue of grease water phase extraction be effectively divided between the grease in aqueous environment in oil plant and oil plant matrix
From the especially separation of grease and protein.Protein not only interfered grease to dissolve out from matrix, but also easily caused dissolution grease
Emulsification.Although extraction efficiency can be improved by certain methods, reduce emulsification degree, as enzyme process improves extraction efficiency, salt effect
The problems such as reduction emulsifies, but there are still at high cost, stability is poor, salt is big to equipment corrosion.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of method for extracting peanut oil using surfactant water phase,
Using peanut seed as raw material, using Surfactant SDS, the surface tension of extractant water is reduced, to increase
It improves oil extraction efficiency with the affinity for being extracted material (fat content is high, and hydrophobicity is strong) conducive to the dissolution of grease.
A kind of method for extracting peanut oil using surfactant water phase provided by the invention, comprising the following steps:
(1) shelled peanut removes peanut red coat, is ground into uniform pulpous state, obtains peanut paste；
(2) peanut paste is mixed with aqueous surfactant solution, after evenly dispersed, stirring is extracted；
(3) after extracting, emulsion layer and boiled oil layer are isolated in centrifugation, are freezed, after defrosting, are centrifuged again, take upper layer clear
Oil.
Shelled peanut described in step (1) removes peanut red coat method particularly includes: by the shelled peanut cleaned out at 80 DEG C
0.5~1.5h of lower heated-air drying, sloughs scarlet.
Present invention 30min or more at 80 DEG C can preferably slough scarlet.Although increasing than traditional handicraft temperature,
But the time shortens.Higher than 80 DEG C, waste of energy, peanut protein denaturation degrees are deepened.Lower than 80 DEG C, it is not easy to remove scarlet.
The solid-to-liquid ratio of peanut paste and aqueous surfactant solution in step (2) are as follows: 1:2~10g/mL；The surface-active
The mass concentration of agent aqueous solution is 0.01%~0.5%, and the aqueous surfactant solution is lauryl sodium sulfate aqueous solution.
Aqueous surfactant solution described in step (2) is oleic acid aqueous solutions of potassium, the mass concentration of oleic acid aqueous solutions of potassium
It is 0.5%~2%.
The present invention controls solid-to-liquid ratio 1:2~10, and solid-to-liquid ratio is too low, and extraction system is sticky, is unfavorable for extracting；Solid-to-liquid ratio is too
Height, wastewater treatment pressure is big, and lauryl sodium sulfate dosage is more, uneconomical, and edible vegetable oil yield is declined, and oil dispersed is in mistake
In the water of amount.
The process conditions that stirring is extracted in step (2) are as follows: 10~60min is extracted in stirring at 25~65 DEG C.Dodecyl
Sodium sulphate belongs to anionic surfactant, itself is to temperature and insensitive.But extraction is mass transport process, mass transfer velocity with
Temperature is related, and molecular motion is accelerated when temperature is high, is conducive to mass transfer, that is, the dissolution of oil is accelerated.Extraction time is short, extracts endless
Entirely, the time long degree that then emulsifies is deepened, and lauryl sodium sulfate and protein have emulsifying capacity.
In step (3), freezing conditions are that 8h or more is freezed at -18 DEG C；Thawing condition is the 30min that thaws at 50 DEG C.Freezing-
Defrosting is a Frozen-thawed cycled, and freezing ruptures emulsion interface film, and the molecule of similar quality reassembles that (small oil droplet is poly- when defrosting
Integrated larger oil droplet, eventually forms edible vegetable oil), it is a demulsification process.In course of defrosting, because content of water in system is very high, if temperature
Excessively high, then protein denaturation speed is accelerated, and 50 DEG C are an acceptable critical values；Temperature is low, and thawing rate is slow.
Compared with prior art, in the present invention, peanut oil is remarkably improved using Surfactant SDS
The edible vegetable oil yield of water phase extraction；Lauryl sodium sulfate concentration used is very low in the present invention, mass concentration be 0.01%~
0.5%, moreover, lauryl sodium sulfate is easy to get, is safe, is inexpensive, it is suitble to food industry applications；It is not required to add other inorganic salts again,
Also, full technical process does not use organic solvent, and product safety is environmental friendly；Raw material is without high-temperature baking, extraction conditions temperature
It is grease obtained without refining with, simple process.
