Description

technical field

[0001] The invention relates to the technical field of membrane treatment, in particular to a soybean isoflavone separation process. Background technique

[0002] Soy isoflavones are flavonoids, a type of secondary metabolites formed during soybean growth, and a biologically active substance. Because it is extracted from plants and has a similar structure to estrogen, soy isoflavones are also called phytoestrogens. The estrogenic effect of soybean isoflavones affects hormone secretion, metabolic biological activity, protein synthesis, and growth factor activity, and is a natural cancer chemopreventive agent.

[0003] In the existing process, the fermented liquid is put into the tank and then passed through the centrifuge after being filtered by the plate and frame. Some manufacturers will also add a double filter device behind the centrifuge. The collected enzyme liquid needs to be further concentrated due to its low enzyme activity. Due to the unique physi...

Embodiment Construction

[0028] now attached figure 1 The present invention will be further described in detail with specific embodiments.

[0029] Concrete embodiment manufacturing steps are as follows:

[0030] A soybean isoflavone separation technology is characterized in that the extraction process steps include:

[0031] Step 1. Fermentation treatment: Grinding soybeans and performing fermentation treatment;

[0032] Step 2, microfiltration filtration: put the fermented liquid of soybean into the primary filtration equipment to obtain the microfiltration dialysate;

[0033] Step 3, decolorization treatment: putting the obtained microfiltration dialysate into an organic decolorization membrane system for decolorization treatment to obtain a decolorization solution;

[0034] Step 4, concentration treatment: adjust the pH of the decolorized solution after the decolorization treatment, and then perform concentration treatment to obtain a soybean isoflavone concentrate;

[0035] Step 5, adjust PH:...
