Abstract

The invention relates to a novel production process for extracting soy isoflavones aglycones. The production process in the invention comprises the following steps of: smashing soy embryos or soy bean meal which serves as a raw material, extracting required ingredients, concentrating, removing proteins, performing column absorption and analysis, concentrating for the second time, performing enzymolysis, extracting a solvent, concentrating for the third time, freeze drying and obtaining the soy isoflavones aglycones. The novel production process for extracting the soy isoflavones aglycones is convenient to operate, high in repeatability and yield and suitable for industrial production; the enzymolysis method is adopted for converting the aglycones, so that the conversion rate is high and the process avoids using poison andharmful solvents; and electrolyte is used for settling the proteins, so that impurity removal is efficient and quick.

Description

technical field [0001] The invention belongs to a natural product extraction process, in particular to a novel production process for extracting soybean isoflavone aglycone. Background technique [0002] Soybean isoflavones are prepared from pure natural high-quality soybeans through modern high-tech purification methods. They have the functions of enhancing immunity, anti-oxidation, preventing aging, and antibacterial. It has a very good effect in reducing the incidence of osteoporosis in middle-aged and elderly women and eliminating menopausal syndrome in women. A number of studies have shown that soybean isoflavones are the best health supplements for women to prevent breast cancer and uterine cancer. However, the existing extraction technology is not ideal, and there are problems such as low yield, complicated operation, low extraction conversion rate, and poor freeze-drying effect. Contents of the invention [0003] In order to solve some unsatisfactory problems in ...
