Description
Technical field
The invention belongs to grease processing technology field, is to belong to a kind of technique of extracting simultaneously soybean phospholipid and pigment from soybean oil specifically.
Background technology
Soybean oil is the vegetables oil kind of China's maximum.Soybean oil can produce the multiple tankage such as oil foot, decolouring roach, deodorization distillate in refining process.Take these tankage as raw material, can the processing soybean phospholipid, the multiple product such as daizeol.
Existing soybean oil refinery practice is take crude oil of soybean as raw material, according to come unstuck, the order of decolouring, depickling, deodorization carries out one by one.
This technique to be adopted and adds the method that water is precipitated out the phosphatide in the crude oil of soybean and come unstuck, and formed precipitation is called as oil foot.
This technique adopts the method decolouring of adding atlapulgite in the crude oil of soybean after come unstuck, and the formed pigment carclazyte that contains is called as the decolouring roach, and wherein contained pigment mostly is the composition that carotenoid, daizeol etc. have nutritive value.
The oil foot that produces and decolouring roach are solid waste, as deal with very easily that corruption becomes improperly, to environment.
Summary of the invention
This patent relates to a kind of eco-friendly, carries out in solvent-extracted mode, and is relatively inexpensive, high efficiency, the soybean oil novel process for refining.More unique is, it relates to a kind of improved technique, this technique is take aqueous ethanolic solution as soybean phospholipid with the extraction solvent of pigment, coming unstuck and decolouring in the soybean oil refining process finished simultaneously, guaranteeing to realize synchronously under the purified soyabean oil quality prerequisite up to standard that other components are as the recovery of by product and the cyclically utilizing of solvent, the soybean phospholipid of co-producing high-purity and soybean pigment, and no longer produce oil foot and decolouring roach.Operate according to this patent, compare with traditional method before this, can be under the prerequisite of the phospholipids content that does not reduce soybean oil and appearance luster quality, make the yield of soybean oil improve 2-3%, and acquisition soybean phospholipid and the other two kinds of products of daizeol that can high-quality high yield, make the production cost decrease, vital for the comprehensive utilization of large oil crops resource that this improvement makes number one for this China of soybean, the efficient utilization of resource rate is greatly increased, greatly improve the degree of utilizing of oil resource, increase utility value.
One of most important purpose of the present invention will solve the continuous production problem of high-quality soybean phospholipid exactly, to reduce production costs, guarantees quality product.As a result along band, another object of the present invention, be to realize serialization that soybean oil comes unstuck, clean, environmental friendliness production.
Specifically, at first, we find that the aqueous ethanolic solution of proper concn can be followed mixing oil/crude oil of soybean layering under suitable temperature, and soybean phospholipid is much higher than its solubleness in mixing oil/crude oil of soybean in the solubleness of aqueous ethanolic solution in mutually.Established thus the basis of the soybean oil degumming and refining technique of the alternative aqueous precipitation method of aqueous ethanolic solution extraction process.
Secondly, we find that the aqueous ethanolic solution of proper concn also has good effect of extracting to the pigment in mixing oil/crude oil of soybean under suitable temperature.Established thus the basis of the soybean oil decolorization refining technique of the alternative activated decoloration method of aqueous ethanolic solution extraction process.
We find that the applicable phosphatide soybean oil that contains can be resulting crude oil of soybean behind resulting mixing oil after leaching, the mixing oil desolvation, also can be that crude oil of soybean is through the resulting oil foot of hydration degum.The suitable concentration of aqueous ethanolic solution is 30%～100% (w/w).The preparation of mixture should be at 30～78 ℃, preferably 45～68 ℃, 0.01～1.0MPa, condition under carry out.The standing demix of mixture should be at-20～60 ℃, preferably 0～20 ℃, 0.01～1.0MPa, condition under carry out.Washing with acetone decolouring should be 0～60 ℃ in temperature, and preferably 10～30 ℃, pressure is to carry out 1-5 time under the condition of 0.1～35MPa, washs 1-5 times that required amounts of acetone should be thick fabaceous lecithin weight at every turn.Carrying out precipitation treatment should be at 30～180 ℃, preferably 50～125 ℃, 0.01～1.0MPa, condition under carry out.The used thermal barrier of carrying out precipitation treatment can be indirect steam, open steam or hot nitrogen.
Among the present invention after the mentioned whole optimizations of all important parameters the yield of finished product purified soyabean oil can improve 2-3% on the basis of existing technique.More than the purity to 80% of gained soybean phospholipid product.
