Description
Technical field
The present invention relates to soybean waste liquid technical fields, more particularly to a kind of reutilization system of high COD soybean waste liquid with high salt
And method.
Background technique
Soya whey wastewater (calling bean clear water in the following text) is that defatted soybean meal alkali extraction-acid precipitation production soybean protein isolate obtains
By-product, production 1t soybean protein isolate need to discharge 30-35t bean clear water.Containing a large amount of recoverables in bean clear water
Substance, such as soybean whey protein, soyabean oligosaccharides and isoflavones, there are also the glycinins not yet precipitated completely, few
The substances such as amount fat and phosphatide, phytic acid.
Soybean whey protein (SoybeanWheyProtein, SWP) is the acid-soluble protein in soybean, and it is total to account for soybean protein
10% or so of content contains 13 kinds of protein, including two kinds of trypsin inhibitors, beta amylase, fat in soy-bean whey
Oxidizing ferment and agglutinin etc..Soybean trypsin inhibitor (SoyBeanTrypsinInhibitors, SBTI) is main in soybean
The anti-nutritional factors wanted, at present it is separated obtain have kunitz trypsin inhibitor
(KuniTztrypsinInhibitor, KTI) and bowman-Birk trypsin inhibitor (Bowman-
BirktrypsinInhibitor, BBI), wherein KTI is single head inhibitor, can inhibit the activity of trypsase, BBI is double end
Inhibitor can inhibit simultaneously the activity of trypsase and chymotrypsin, to reduce the nutritive value of soybean protein and eat peace
Quan Xing.For food industry, need to remove or inactivate SBTI to improve the nutritive value of bean product.It is continuous with research
