Typical Specifications for 90% Soy Protein Isolate
Commercial soy protein isolate is commonly selected by dry-basis protein content, moisture, ash and functional characteristics. The figures below are typical reference limits for a 90% isolate grade, not a published Certificate of Analysis for a specific Unilong batch.

|---|---|
| CAS Number | 9010-10-0 |
| EC Number | 232-720-8 |
| Appearance | Off-white to light yellow powder |
| Protein Content (Dry Basis, N × 6.25) | ≥90.0% |
| Moisture | ≤7.0% |
| Ash (Dry Basis) | ≤6.0% |
| Crude Fat | ≤1.0% |
| Physical Form | Fine powder |

Final specification limits and testing methods depend on the offered grade. Confirm any microbiological, contaminant, allergen or certification requirements with your quotation.
Soy Protein Isolate Applications
Processed Meat and Sausage Products
Soy protein isolate is used in sausages, meat emulsions, processed poultry and formulated meat products requiring protein enrichment, moisture retention and fat binding. Suitable grades contribute to emulsion stability and processing texture.
Plant-Based Meat Alternatives
The ingredient contributes concentrated plant protein, binding and texture development to meat-free burgers, patties and fillings. Powdered soy protein isolate is different from textured soy protein designed for fibrous structure.
Protein Beverages and Dairy Alternatives
Selected grades are used in protein beverages, dairy alternatives and powdered drink mixes. Dispersibility, flavor profile, suspension behavior and formulation stability are important grade-dependent characteristics.
Nutritional Powders and Protein Blends
Protein powders, meal-replacement mixes and manufactured nutritional blends use soy protein isolate to raise protein concentration. Particle size, flavor and dispersibility influence the formulation choice.
Bakery, Cereals and Protein-Enriched Snacks
Soy protein isolate can be included in bakery, cereal-based and protein-enriched snack formulations. Depending on the formulation and grade, it contributes protein while affecting moisture management and finished-product texture.

Packaging, Stock and Delivery
Commercial Packing
Common soy protein isolate packing formats include 20 kg or 25 kg bags, often with moisture-protective liners. Actual packing materials, unit weights and labeling are specified in the quotation.
Trial and Bulk Quantities
One-bag (25 kg) trial-order enquiries are welcome, subject to the offered grade and pack size. Quotations can also cover 500 kg, 1 MT and multi-ton requirements.
Current Stock
Availability is checked against the required grade, batch and order quantity. Where suitable inventory is available, a specific dispatch date can be discussed.
Dispatch Timeline
Unilong's standard shipment guidance is usually 7–15 days from confirmed order. International transit and customs clearance depend on the agreed delivery terms and destination.
Storage
Store in sealed packaging in a cool, dry and well-ventilated location. Protect the powder from humidity, direct sunlight and strong odors.
Quality Documentation
Quality and regulatory requirements depend on the intended market and selected grade. Documentation enquiries may cover the following items:
- Certificate of Analysis (COA) for the applicable product or batch
- Technical Data Sheet (TDS) and Safety Data Sheet (SDS), where applicable
- Protein, moisture, ash and grade-specific microbiological specifications
- Soy allergen information
- Non-GMO status or other certifications, if supported for the offered grade
Documents and certification status are confirmed for the actual source and grade. Soy protein isolate is derived from soybeans and contains soy protein; finished-product allergen labeling must follow the requirements of the destination market.

Frequently Asked Questions
Is soy protein isolate in stock?
Stock depends on the requested grade and current inventory. Share the target protein content and order quantity to check available lots and possible dispatch dates.
What is the minimum order quantity?
Enquiries for one-bag trial orders, typically 25 kg, are welcome. The applicable MOQ is confirmed for the actual grade and packing configuration.
How long does shipment take?
Under Unilong's standard service policy, shipment is usually arranged within 7–15 days after confirmation. An actual dispatch date is included in the quotation; international transit is additional.
Can samples be arranged before a bulk order?
Customers may enquire about samples for manufacturing evaluation. Under Unilong's standard service, approved and available samples are normally dispatched within 2–3 days after confirmation.
What protein content is typical?
Soy protein isolate is commonly specified at ≥90% protein on a dry basis. Grade-specific specifications and analytical methods should be confirmed before ordering.
Is it suitable for plant-based meat or protein drinks?
Yes. Soy protein isolate is used in both application groups, although the required binding, dispersibility and flavor characteristics depend on the grade and finished formulation.
Can I request COA, TDS or certification documents?
Yes. Submit your documentation requirements with the inquiry. Document availability is verified for the selected product grade and source.
How does it differ from soy protein concentrate?
Soy protein isolate typically contains at least 90% protein on a dry basis, whereas soy protein concentrate commonly contains about 65–70%. They differ in concentration and can have different formulation performance.
