Production Process of Hydrolyzed Soy Protein

The production of hydrolyzed soy protein involves several steps, including the extraction of soy protein, hydrolysis, and purification. Here is an overview of the process:

Extraction of Soy Protein

The first step in producing hydrolyzed soy protein is the extraction of soy protein from soybeans. This involves:

Cleaning and dehulling the soybeans to remove impurities.
Grinding the soybeans into a fine powder.
Extracting the protein using water or alkaline solutions.
Precipitating the protein using acid or heat treatment.

Hydrolysis

The extracted soy protein is then subjected to hydrolysis, which can be achieved using enzymes or acids. The hydrolysis process involves:

Adding enzymes or acids to the protein solution to break down the protein into smaller peptides and amino acids.
Controlling the hydrolysis conditions, such as temperature, pH, and time, to achieve the desired degree of hydrolysis.
Monitoring the hydrolysis process to ensure consistent quality and functionality.

Purification

After hydrolysis, the resulting product is purified to remove any remaining impurities and by-products. This involves:

Filtration to remove insoluble materials.
Centrifugation to separate the hydrolyzed protein from the liquid phase.
Drying to produce a powdered form of hydrolyzed soy protein.

📝 Note: The specific conditions and methods used in the production process can vary depending on the desired properties and applications of the hydrolyzed soy protein.
