Soy Protein Isolate (Non-Textured)

Soy Protein Isolate (Non-Textured) is a highly refined, concentrated protein powder derived from soybeans (Glycine max). It is produced by removing the majority of non-protein components—including carbohydrates (oligosaccharides), fats, fiber, and ash—from defatted soy flour, resulting in a product that is ≥90% protein on a dry basis. The 'non-textured' designation means it has not undergone extrusion, texturization, or other mechanical processes to create fibrous, meat-like structures; it remains in its native powdered or granular form with minimal processing beyond isolation. It is considered a complete protein, containing all nine essential amino acids, though it is relatively lower in methionine and cysteine compared to animal proteins like whey or casein. It exhibits excellent functional properties including high water solubility, emulsification, fat binding, and gelation. It has a neutral, bland flavor profile, making it versatile for fortification without significantly altering taste. Widely used in nutritional supplements, meal replacements, protein powders, sports nutrition products, infant formulas, functional foods, and medical nutrition due to its high protein quality, digestibility (PDCAAS ~1.0), and cost-effectiveness.
