Key benefits
- One of the highest protein loadings available from a plant source — 35 g of protein in a 40 g serving.
- Complete amino acid profile, including 6 g BCAA and 13 g EAA per serving.
- Fully soluble in cold water, so it needs no heating or high-shear mixing to disperse.
- High dispersibility and low viscosity, which keeps mouthfeel light in ready-to-mix beverages.
- Strong water absorption and binding, and good fat emulsification, for use in bars and blended systems.
- Plant-based and Non-GMO, with no added flavour, colour or sweetener.
What it is
Soy Protein Isolate 90% is the most refined form of soy protein — the carbohydrate and fat fractions have been removed, leaving a powder that is at least 90% protein on a dry basis. This grade is cold water soluble, which matters in practice: it disperses without heating, so it can go into a ready-to-mix sachet or a bottled beverage without a hot processing step.
It is unflavoured and unsweetened, which leaves the flavour system entirely in your hands.
Functional properties
Beyond the protein number, this grade was selected for how it behaves in a formulation:
- High affinity for water absorption and binding — useful in bars, extruded products and anywhere texture depends on moisture control.
- Excellent dispersion and fat emulsification — it holds an emulsion rather than separating.
- High dispersibility, low viscosity — it mixes into a beverage without turning it into a gel, which is the usual complaint with cheaper protein grades.
- Good antioxidant properties, contributing to the stability of the finished product.
- Clean flavour, functionality and mouthfeel, so it does not fight the flavour system.
Where it is used
Sports nutrition powders and RTD beverages · weight-management products · high-protein fortification of foods · general health and wellness formats · as a dairy alternative in plant-based beverages.
