Whether you are a fitness enthusiast, a homemaker or a young adult, we all have protein requirements, don't we? With so many protein supplements out there, choosing the right one can be confusing. However, in the quest to find the most suitable, healthy, clean protein, we are sure the hype around soya protein must have caught your eye.


Soya protein is popular and one of the best choices for those wanting a plant-based protein that is free from chemicals and additives. But soya protein itself has two categories: Soya Protein Isolate and Soya Protein Concentrate. So, if you are also wondering what the difference between Soy Protein Isolate vs Concentrate and which one you should choose, let us help you.


Why is Soya Protein Essential?


Soya protein is a fantastic protein alternative for vegans and vegetarians who want to add complete, high-quality protein to their diets. It contains all nine essential amino acids that our body cannot produce on its own, making it a complete protein source. Plus, it's low in fat, cholesterol-free, and packed with nutrients.


It is safe for heart health and helps improve one's immunity. Whether you are aiming to build muscles, maintain a healthy lifestyle or want quick repair and recovery, soya protein can be the choice for your daily routine.

Explore our range of soya protein isolate and concentrate to meet your daily protein requirements naturally.

What is Soya Protein Concentrate?


Soy protein concentrate is made by removing the water-soluble carbohydrates from defatted soy flakes. This process leaves behind a residue of about 70% protein, with the remaining portion being carbohydrates and some fats. The resulting product is a fine powder that can be easily mixed into shakes, baked goods, or other recipes.


How is Soya Protein Concentrate Made?


  1. Defatting Soyabeans: Soybeans are dehulled and defatted to remove oils, producing defatted soy flakes.

  2. Removal of Carbohydrates: The defatted soy flakes are treated with water, alcohol, or acid to remove soluble carbohydrates, concentrating the protein content.

  3. Drying and Grinding: The protein-rich residue is dried and ground into a fine powder, resulting in soy protein concentrate.


What is Soya Protein Isolate?


Soy protein isolate is the more refined version of soya protein. It contains about 90% protein, making it one of the purest forms of plant-based protein available. Most of the fats and carbohydrates are removed during processing, leaving a high protein concentration.


How is Soya Protein Isolate Made?


  1. Defatting Soyabeans: Soyabeans are dehulled and defatted to produce protein-rich defatted soya flakes.

  2. Protein Extraction: The protein is dissolved from the defatted flakes using water or an alkaline solution.

  3. Protein Separation: The dissolved protein is separated by adjusting the pH, allowing it to form a solid while the non-protein components remain in the solution.

  4. Purification: The leftover protein is washed and cleaned to purify it further.

  5. Drying and Milling:  The purified protein is dried and ground into a fine powder, soy protein isolate.


Comparison Between Soy Protein Isolate vs Concentrate


  1. Protein Content: Soya protein isolate contains around 90% protein, making it a highly concentrated source. On the other hand, soya protein concentrate has approximately 70% protein.

  2. Nutrient Profile: Soy protein concentrate retains more natural nutrients, such as dietary fibre, vitamins, and minerals, than the more processed soy protein isolate, which primarily focuses on delivering a high protein content.

  3. Processing Levels: Soay protein concentrate undergoes less processing, preserving more of the natural compounds found in soy, such as isoflavones. Soya protein isolate undergoes extensive processing to remove fats and carbohydrates, producing a purer protein product.

  4. Digestion: Isolate is designed for quick absorption and is ideal for post-workout recovery. Concentrate requires more time for digestion. Its high fibre content provides satiety and supports gut health.

  5. Dietary Applications: Soya protein isolate is suited for those requiring a low-fat, low-carb and high-protein supplement. The concentrate is ideal for generally anyone seeking protein requirements without specifications.

  6. Health: Both protein sources aid in quick muscle recovery and muscle building, help manage cholesterol levels, and reduce the chances of heart-related diseases.

  7. Texture: Soya protein concentrate has a coarser texture, which can be slightly grainy. Soya protein isolate is smoother and ideal for blending into drinks and achieving a creamier texture. Additionally, isolate has a mild taste and can be easily added to various recipes.

Final Thoughts: Which Soya Protein is Superior?


Both soya protein supplements have benefits and drawbacks. However, if you are looking for a high-protein content with minimal fats and carbs, Soya Protein Isolate should be your choice.
