As with any food or supplement, it is important to do your own research and consult with a healthcare professional before incorporating isolated soy protein into your diet.
How is Isolated Soy Protein Produced?
The process of isolating soy protein involves several steps. Firstly, the soybeans are soaked, ground, and mixed with water to form a slurry. Next, the slurry is filtered to remove the insoluble components, leaving behind a liquid that is predominantly protein. The liquid is then acidified to precipitate the protein out of the solution. Finally, the protein is washed, dried, and packaged for use.
Isolated soy protein is a popular ingredient in many food products due to its high protein content and versatility. It can be used as a meat substitute in vegetarian and vegan dishes, as well as in protein bars and shakes for athletes and fitness enthusiasts.
However, some people may have concerns about the production process of isolated soy protein. The use of acid to precipitate the protein can result in the formation of compounds called phytates, which can reduce the absorption of certain minerals in the body. To address this issue, some manufacturers use a different process called enzymatic hydrolysis, which does not involve the use of acid and results in a product with lower levels of phytates.
