Side-by-side framing for formulators choosing between Proteluxe pea isolate (P85) and soy isolate (SPI 90) — including DIGEST+ enzyme-enhanced systems manufactured by Aspire Biozymes.
Proteluxe combines high-quality plant protein isolates with optional plant-derived proteolytic enzymes (DIGEST+) for stronger nutritional positioning, digestibility support and functional performance in food, beverage and wellness applications.
>85% protein · Quality yellow peas · Non-soy positioning
~90% protein · Quality soybeans · High-protein soy systems
Indicative guidance for formulators. Confirm lot specifications via TDS / COA. For concentrate vs isolate pea detail, also see P60 / P85 / SPI 90.
| Attribute | Pea protein (P85 / P60) | Soy protein (SPI 90) |
|---|---|---|
| Source | Yellow pea | Soybean |
| Proteluxe grades | P85 isolate · P60 concentrate | SPI 90 isolate |
| Typical protein % | >85% (P85) · ~60% (P60) | ~90% |
| Amino acid framing | High-protein pea profile; pair for balanced claims where needed | Complete protein / strong EAA profile |
| Allergen note | Pea (label as required) | Soy (label accordingly) |
| Positioning | Non-soy / pea-based nutrition | High-protein soy systems |
| Taste | Neutral / mild pea isolate profile (P85) | Neutral soy isolate profile |
| Solubility / dispersibility | Excellent for P85 — validate in matrix | Excellent — process-dependent; validate in matrix |
| Functionality | Emulsification, thickening, water binding | Emulsification, gelation, water binding |
| Typical use | Sports, beverages, bars, plant-based (P85); enrichment (P60) | Sports, beverages, plant-based, bars, dairy alternatives |
| DIGEST+ option | P85 DIGEST+ · P60 DIGEST+ | SPI 90 DIGEST+ |
DIGEST+ systems pair the same protein bases with papain and bromelain to support digestion, protein utilisation and comfort in finished nutrition concepts — without changing the core protein choice.
Base isolates vs DIGEST+ systems — same protein density, stronger digestibility positioning when enzymes are included.
