Unveiling the Extraction Process of Soy Peptides

July 12, 2024

What is soy peptide?

Soy peptides are bioactive peptides extracted from soy protein, with molecular weights ranging from 1000 to 3000 and a relatively simple structure. Soy peptides have a wide range of physiological activities, such as antibacterial, anti-tumor, and cardiovascular protection, and are widely used in the fields of health products and medicine.

Extraction process of soy peptides

1. Protein extraction

Soy protein is the initial source of soy peptides, so the first step is to extract protein from soybeans. Usually, water extraction or ethanol extraction is used. The water extraction method is to grind soybeans into fine powder, then add water and stir to dissolve the protein in water, and separate the protein through methods such as centrifugation or membrane filtration. The ethanol extraction method utilizes the different solubility of ethanol in soy protein to separate the protein.

2. soybean milk filtration

After the protein is separated, insoluble substances and impurities need to be filtered out to get clear soybean milk.

3. Precipitation

The protein in soybean milk is added with a certain amount of acid or salt for precipitation, so that the protein can be condensed into solid particles. After precipitation, solid particles are separated by centrifugation or membrane filtration methods.

4. Purification

Dissolve solid particles and purify them through high-performance liquid chromatography, ion exchange, and other purification operations to obtain high purity soy peptides.

The influence of process flow on the content of soybean peptides

Different production processes have an impact on the content of soy peptides. If the protein in soybean residue is extracted with water to obtain soy protein, its soy peptide content is relatively low; By using ethanol extraction method, protein powder rich in soy peptides can be obtained.

Conclusion

The extraction process of soy peptides is multi-step and complex, requiring attention to the operational details of each step to ensure the quality of the final product. Different production processes have an impact on the content of soy peptides, and the selection needs to be based on the actual situation.
