Description
Technical field
The invention belongs to vegetable oil extraction field, be specifically related to a kind of method utilizing tensio-active agent aqueous phase to extract peanut oil.
Background technology
Along with the raising of people's living standard, the consumption of food oils remains high, and the main source of food oils is Vegetable oil lipoprotein.Extracting method many employings organic solvent extraction of existing Vegetable oil lipoprotein.Conventional grease extraction agent is industrial hexane and 6# solvent oil (mixture of short hydrocarbon).
But, prove that the volatilization of organic solvent in grease extraction production is one of important sources of topsoil.The enhancing day by day of environmental protection pressure, makes innovation grease extractive technique become inevitable.Dissolvent residual is had in addition in processed oil, unhelpful to HUMAN HEALTH.
Grease aqueous phase abstraction technique is the technique of a kind of green, environmental protection, safety, is expected to alternative grease organic solvent extract technology in the future, also day by day deep to its research.
Grease aqueous phase extraction process is still faced with three large technical bottlenecks at present: one is that grease extraction efficiency is low, and two is that emulsification is serious, and edible vegetable oil yield is low, and three is waste water handling problems.The main problem wherein affecting grease aqueous phase extraction process industrial applications is the problem that grease extraction efficiency is low, makes the economy of technique not high.For this reason, actively improve grease aqueous phase extracting process, improve grease extraction efficiency, become the important prerequisite that grease aqueous phase extraction process realizes industrial applications.
The key issue of grease aqueous phase extraction is that can grease in aqueous environment in oil plant effectively be separated with between oil plant matrix, being particularly separated of grease and protein.Protein had both hindered grease stripping from matrix, easily caused again the emulsification of stripping grease.Although improve extraction efficiency by certain methods, reduce emulsification degree, as enzyme process improves extraction efficiency, salt effect reduction emulsification, but still there is the problems such as cost is high, poor stability, salt pair equipment corrosion are large.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of method utilizing tensio-active agent aqueous phase to extract peanut oil, take peanut seed as raw material, utilize Surfactant SDS, reduce the surface tension of extraction agent water, thus increase itself and the avidity being extracted material (fat content is high, and hydrophobicity is strong), be beneficial to the stripping of grease, improve oil extraction efficiency.
A kind of method utilizing tensio-active agent aqueous phase to extract peanut oil provided by the invention, comprises the following steps:
(1) Semen arachidis hypogaeae removes Testa arachidis hypogaeae, is ground into uniform pulpous state, obtains peanut paste;
(2) peanut paste is mixed with water phase surfactant mixture, after dispersed, stir and extract;
(3), after extraction terminates, centrifugal, isolate emulsion layer and boiled oil layer, freezing, after thawing, recentrifuge, gets upper strata edible vegetable oil.
Semen arachidis hypogaeae described in step (1) removes the concrete grammar of Testa arachidis hypogaeae: by the Semen arachidis hypogaeae warm air drying 0.5 ~ 1.5h at 80 DEG C cleaned out, slough scarlet.
The present invention more than 30min at 80 DEG C can slough scarlet preferably.Although increase than traditional technology temperature, time shorten.Higher than 80 DEG C, waste energy, Semen arachidis hypogaeae protein denaturation degrees is deepened.Lower than 80 DEG C, not easily remove scarlet.
In step (2), the solid-to-liquid ratio of peanut paste and water phase surfactant mixture is: 1:2 ~ 10g/mL; The mass concentration of described water phase surfactant mixture is 0.01% ~ 0.5%, and described water phase surfactant mixture is lauryl sodium sulfate aqueous solution.
Water phase surfactant mixture described in step (2) is the potassium oleate aqueous solution, and the mass concentration of the potassium oleate aqueous solution is 0.5% ~ 2%.
The present invention controls solid-to-liquid ratio 1:2 ~ 10, and solid-to-liquid ratio is too low, extraction system thickness, is unfavorable for extracting; Solid-to-liquid ratio is too high, and wastewater treatment pressure is large, and sodium lauryl sulphate consumption is many, uneconomical, and edible vegetable oil yield declines to some extent, and oil dispersion is in excessive water.
Stirring the processing condition extracted in step (2) is: at 25 ~ 65 DEG C, stir extraction 10 ~ 60min.Sodium lauryl sulphate belongs to aniorfic surfactant, and itself is insensitive to temperature.But extracting is a mass transfer process, and mass transfer velocity is relevant with temperature, during temperature height, molecular motion is accelerated, and is beneficial to mass transfer, and the namely stripping of oil is accelerated.Extraction time is short, extracts not exclusively, and time long then emulsification heighten degree, sodium lauryl sulphate and protein have emulsifying capacity.
In step (3), freezing conditions is freezing more than 8h at being-18 DEG C; Thawing condition is the 30min that thaws at 50 DEG C.Freeze-thaw is a freeze-thaw cycle, freezingly makes emulsion interface film rupture, and when thawing, the molecule of similar quality reassembles (little oil droplet coalescence becomes larger oil droplet, finally forms edible vegetable oil), is a breakdown of emulsion process.In course of defrosting, because content of water in system is very high, if temperature is too high, then protein denaturation speed is accelerated, and 50 DEG C is an acceptable threshold value; Temperature is low, and thawing rate is slow.
Compared with prior art, in the present invention, utilize Surfactant SDS can significantly improve the edible vegetable oil yield of peanut oil aqueous phase extraction; In the present invention, sodium lauryl sulphate concentration used is very low, and mass concentration is 0.01% ~ 0.5%, and sodium lauryl sulphate is easy to get, safe, inexpensive, be applicable to food industry applications; Do not need to add other inorganic salt again, and, full technological process not with an organic solvent, product safety, technique environmental protection; Raw material is without high bake, and extraction conditions is gentle, and technique is simple, grease obtained without the need to refining.
