About this supplement

Soy Protein Isolate (Textured) is a highly refined, concentrated form of soy protein that has been processed to remove most carbohydrates, fats, and other non-protein components, resulting in a protein content typically exceeding 90% on a dry basis. The 'textured' variant is produced through extrusion processing, which imparts a fibrous, meat-like structure, making it valuable as a meat analog or extender. It is derived from defatted soy flour and serves as a complete protein source containing all nine essential amino acids, with a relatively high proportion of branched-chain amino acids (BCAAs) like leucine. This form is particularly valued in food applications for its functional properties, including water and fat binding, emulsification, and texture modification.

How much to take

Typical amount
Used as a food ingredient, not typically dosed like a supplement. As a protein source, servings range from 15-30 grams of dry textured protein (providing ~12-25g protein).
Suggested range
Not applicable as a standardized supplement; intake depends on dietary protein goals and food formulation.

Physical properties

Typically light tan to brown granules, chunks, or flakes with a porous, spongy texture. Hydrates readily in water or broth, absorbing 2-3 times its weight in liquid, becoming chewy and fibrous. Soluble in water after processing. Dry form has a long shelf life.

How it’s made

Produced from defatted soy flour or soy protein concentrate. The material is mixed with water, subjected to high temperature and pressure in an extruder, and then forced through a die. The sudden pressure drop causes steam flash-off, creating a porous, fibrous matrix. It is then dried, sized, and packaged.
