Why Choose Greenherb Soy Protein Isolate Powder?

• Non-GMO Soybean Sourcing – Greenherb procures identity-preserved, non-GMO soybeans from certified farms, meeting customs and regulatory testing requirements for import into EU, North America, and Asia.

• High Protein & Low Impurities – Our soy protein isolate powder delivers ≥90% protein (Kjeldahl N×6.25) with less than 1% fat and 4% ash, third-party verified.

• Clean Water-Based Extraction – No hexane or harsh solvents; isoelectric precipitation followed by spray drying preserves native protein structure and functionality.

• Batch-to-Batch Consistency – Each lot is tested for protein content, gel strength, emulsification capacity, heavy metals, and microbiology by independent ISO/IEC 17025 laboratories.

• Excellent Functional Properties – High water absorption (≥4:1), strong gelation at 80–90°C, and good emulsification for meat analogs, dairy alternatives, and baked goods.

• Neutral Flavor Profile – Light beany notes easily masked; heat treatment reduces off-flavors, suitable for neutral or flavored applications.

• Multiple Packaging Options – Various bag and drum sizes available for lab, pilot, and bulk orders.

• Complete Customs & Regulatory Support – Every shipment includes COA, MSDS, non-GMO certificate, phytosanitary certificate (if required), and third-party test reports for heavy metals, aflatoxins, and microbiology.

• Global Logistics – Greenherb coordinates with experienced freight forwarders to ensure timely delivery to any major port, with full export documentation for smooth customs clearance.

• Competitive Pricing – Factory-direct pricing with volume discounts for full container loads and flexible terms for repeat customers.

Product Introduction

Soy Protein Isolate Powder is the highest purity form of soy protein, produced by removing non-protein components (fiber, soluble carbohydrates, ash) from defatted soybean flakes. Unlike soy protein concentrate (70% protein), the isolate offers ≥90% protein density, making it a cost-effective complete amino acid source (PDCAAS = 1.0) for vegetarian, vegan, and mainstream nutritional products.

Greenherb’s soy protein isolate powder is water-extracted and spray-dried, resulting in a light cream powder with high dispersibility. For customers requiring soy protein bulk quantities, we provide consistent lots with full traceability. It is widely used in meat alternatives, protein beverages, and nutritional bars.

Production Process

Greenherb produces Soy Protein Isolate Powder through a clean, solvent-free process:

1. Cleaning and dehulling of non-GMO soybeans

2. Flaking and defatting (mechanical pressing or supercritical CO₂ – no hexane)

3. Water extraction of soluble proteins at alkaline pH

4. Separation of fiber and insoluble carbohydrates

5. Isoelectric precipitation at pH 4.5 to recover protein curd

6. Washing and neutralization to pH 6.8–7.2

7. Spray drying (inlet temperature 160–180°C) to fine powder

8. Milling and sieving to target particle size

9. Metal detection, blending, and final packaging

Functional Properties & Benefits

Soy Protein Isolate Powder offers multiple advantages for food and supplement manufacturers:

• Complete Amino Acid Profile – Contains all essential amino acids; PDCAAS of 1.0 comparable to animal proteins, rich in arginine and glutamine.

• High Gelation & Texturization – Forms firm, resilient gels when heated, ideal for plant-based meat and fish analogs.

• Water & Fat Binding – Absorbs 4–5 times its weight in water, improving juiciness and mouthfeel in processed foods.

• Emulsification – Stabilizes oil-in-water emulsions in sauces, soups, and plant-based dairy.

• Heat Stability – Withstands retort and autoclave processing without losing functionality.

• Supports Muscle Health – Leucine-rich protein for muscle protein synthesis in sports nutrition.

• Hypoallergenic – While soy is an allergen, our facility manages cross-contact; allergen statements available upon request.
