Problems solved by technology

[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 physical and chemical properties of enzymes, they can only be concentrated under medium and low temperature conditions, and the enzymes will be inactivated under high temperature conditions. However, the traditional vacuum concentration and thin film evaporation have the disadvantages of huge energy consumption and long time consumption.

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:...

Abstract

The invention discloses a soybean isoflavone separating technology. An extraction process comprises the steps of 1 fermentation treatment, 2 microfiltration filtering, 3 decolorizing treatment, 4 concentration treatment, 5 PH regulating, 6 concentration and crystallization, 7 rinsing treatment, 8 drying treatment and 9 crystallizing and crushing. The soybean isoflavone separating technology is a production process which can be safely and efficiently used for a long term and is convenient to maintain, the production process is simple, and meanwhile the production cost is reduced.

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...
