Abstract
The method that the present invention relates to a kind of to recycle concentrating soya lecithin from soy molasses, this approach includes the following steps：（1）The soy molasses that alcohol processed soybean protein concentrate generates will be produced and be diluted with water to pol 10-30, pH to 5.5-7.5 is adjusted, be heated to 40-70 DEG C, under the pressure of 0.1-0.3MPa, be concentrated by microfiltration membranes；（2）Step（1）Obtained concentrate is added ethyl alcohol and n-hexane mixed liquor, separates after mixing in closed container, obtain lipid phase and water phase；（3）Step（2）Obtained lipid phase evaporation recycling n-hexane, products obtained therefrom is concentrating soya lecithin；Advantage is：Compared with prior art, the present invention is concentrated the soybean lecithin in soy molasses using membrane filtration technique, then obtains concentrating soya lecithin product using Double solvent method extraction and separation, technology is suitble to industrial-scale production.
Description
Technical field
The present invention relates to a kind of food processing technology more particularly to a kind of sides that soybean lecithin is recycled from soy molasses
Method.
Background technique
Soybean lecithin be it is a kind of it is faint yellow to brown, odorless or slightly odorous flowing liquid sticky mass, it is main
Three kinds of constituents include lecithin, cephalin and lipositol.Soybean lecithin include bread, it is milk powder, chocolate, artificial
It is widely used in terms of the food processings such as cream, ice cream.In field of medicaments application, for neurasthenia, tired with brain
The feel of the symptoms such as labor, failure of memory and senile dementia has apparent control efficiency.It can accelerate in feed processing as emulsifier
Fat dispersion improves fat utilization rate.Therefore, soybean lecithin has huge market in different industrial circles.
Soybean lecithin is mainly so that the byproduct of soybean oil aquation degumming --- soybean oil residue is raw material, not yet at present
Phosphatide in soy molasses is recycled.And contain soybean lecithin about 5%-10% in soy molasses, due to not recycling
And cause the waste of resource.
The method for extracting soybean lecithin in the soy molasses of documents and materials report at present mainly has：（1）Utilize organic solvent
It is extracted in soy molasses directly after dilution, then recycles organic solvent and obtain raw phospholipid, this method makes organic solvent
Dosage and consumption are all bigger；（2）It is co-precipitated the soybean lecithin in a part of soy molasses using the method for the heavy albumen of acid, so
It is extracted afterwards with organic solvent, the phosphatide in a part of molasses can only be precipitated during this method acid is heavy, and cannot all recycled.
Summary of the invention
One kind is provided and recycles soybean lecithin from soy molasses it is an object of the invention to avoid the deficiencies in the prior art
Method.
The technical scheme is that：
A method of it recycling concentrating soya lecithin from soy molasses, includes the following steps：
1）Will produce alcohol processed soybean protein concentrate generate soy molasses be diluted with water to pol be 10-30, be separately added into hydrochloric acid,
Sulfuric acid, nitric acid, acetic acid, citric acid, lactic acid, tartaric acid, apple acid for adjusting pH to 5.5-7.5, are heated to 40-70 DEG C, in 0.1-
Under the pressure of 0.3MPa, it is concentrated by microfiltration membranes；
2）Step 1）Obtained concentrate is added ethyl alcohol and n-hexane mixed liquor, separates after mixing in closed container,
Obtain lipid phase and water phase；
3）Step 2）Obtained lipid phase evaporation recycling n-hexane, products obtained therefrom is concentrated phosphatide.
Step 1）Described in microfiltration membranes material therefor be selected from ceramic membrane, stainless steel membrane, membrane aperture is in 50-200nm.
Step 1）Described in micro-filtrate membrane filtration obtain micro-filtration concentrate using complete alternation concentration formats.
Step 2）Described in ethyl alcohol and n-hexane mixed solution, volume ratio 1:1-3, concentrate with mix it is organic molten
The volume ratio of agent is 3-6:1.
Step 2）Described in lipid phase and aqueous phase separation use revolving speed for 3000-5000rpm centrifuge be centrifugated, it is right
The phosphatide of emulsified state is demulsified.
Compared with prior art, the beneficial effects of the invention are as follows：Effectively by the soluble polysaccharide in soy molasses, solubility
Albumen removal, operating procedure is simple, and process is few, and the rate of recovery is high, is suitble to industrial-scale production.
Specific embodiment
