What exactly is Soy Protein Isolate?
Soy Protein Isolate features a protein concentration exceeding 90% (on a dry basis). Through the advanced isolation process, carbohydrates, fats, and insoluble fibers are removed, leaving only the most functional protein fractions.
- A Complete Protein: Providing all 9 essential amino acids with a PDCAAS (Protein Digestibility Corrected Amino Acid Score) of 1.0, which stands as a premium-tier protein source equal to whey and casein.
- Multi-Functional Performance: Designed for excellence in emulsification, moisture retention, film formation, and viscoelasticity—essential for structural optimization in food science.
