Certificate of Analysis
Product Introduction
Pure Soy Protein Powder is a high-purity plant protein isolate derived from dehulled, defatted soybean flakes. Through isoelectric precipitation and washing, non-protein components (fiber, soluble carbohydrates, ash) are removed, leaving a protein concentrate that is >90% protein on a dry basis. Unlike soy protein concentrate (70% protein) or textured soy protein, the “pure” powder form offers maximum protein density, clean flavor, and versatile functionality.
Greenherb’s pure soy protein powder is neutral in taste, light in color, and disperses well in both aqueous and oil-containing systems. It serves as a cost-effective, complete amino acid source (PDCAAS = 1.0) for vegetarian, vegan, and mainstream nutritional products.

Key Characteristics:
-
Source: Non-GMO soybeans (Glycine max)
-
Processing: Water extraction, isoelectric precipitation, spray drying
-
Appearance: Off-white to cream fine powder
-
Solubility: Dispersible in water (forms colloidal suspension); soluble in alkaline pH
-
Flavor: Neutral, slightly beany (heat treatment reduces beany notes)
-
Isoelectric Point: pH 4.5
Production Process
Greenherb produces Pure Soy Protein Powder through a clean, solvent-free process:
-
Cleaning and dehulling of non-GMO soybeans
-
Flaking and defatting (mechanical pressing or supercritical CO₂ – no hexane)
-
Water extraction of soluble proteins at alkaline pH
-
Separation of fiber and insoluble carbohydrates
-
Isoelectric precipitation at pH 4.5 to recover protein curd
-
Washing and neutralization to pH 6.8–7.2
-
Spray drying (inlet temperature 160–180°C) to fine powder
-
Milling and sieving to target particle size
-
Metal detection, blending, and final packaging

Functional Properties & Benefits
Pure Soy Protein 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.
-
High Solubility (NSI ≥70%) – Dissolves well in beverages and liquid formulas; minimal sedimentation.
-
Water & Fat Binding – Absorbs 4–5 times its weight in water, improving texture in meat analogs and baked goods.
-
Emulsification – Stabilizes oil-in-water emulsions in sauces, soups, and plant-based dairy.
-
Heat Stability – Withstands pasteurization and retort processing without losing functionality.
-
Non-Allergenic Option – While soy is an allergen, our facility manages cross-contact; allergen statements available.
-
Supports Muscle Health – Leucine-rich protein for muscle protein synthesis in sports nutrition.
