Soya Protein Isolate 90%

What Is Soya Protein Isolate 90%?

Soya Protein Isolate is produced from defatted soybean meal through aqueous extraction and precipitation, removing most carbohydrates and fats to yield approximately 90% protein by dry weight. Soy is notable among plant proteins for containing all nine essential amino acids in meaningful amounts — one of the few single plant sources that approaches a complete amino acid profile, though its DIAAS score sits modestly below dairy reference proteins.

Common Mistakes

Overlooking allergen labeling. This is the single most common and consequential mistake — soy allergen declarations are mandatory in most markets.

Assuming SPI behaves identically to WPI in beverage applications. Flavour and emulsification profiles differ meaningfully — always sample-test.
