Product Overview
Soybean extract is a broad category of bioactive compounds derived from the seeds of Glycine max, the common soybean plant. Recognized globally for its rich concentration of phytoestrogens, phospholipids, and functional nutrients, soybean extract has established itself as a cornerstone ingredient across the dietary supplement, nutraceutical, cosmetic, food additive, and pharmaceutical industries.
At Extract Makers, we supply pharmaceutical-grade soybean extract in multiple standardized specifications, offering consistent quality, verified potency, and full batch traceability to meet the demands of formulators, brand owners, contract manufacturers, and international distributors.
Available Specifications:
- Soy Isoflavones: 20%, 40% (by HPLC)
- Soybean Lecithin PC: 98%
- Phosphatidylserine (PS): 20%, 50%, 70%
Raw Material Sourcing & Extraction Process
Our soybean extract is produced from non-GMO soybean seeds cultivated in regions known for premium-grade legume agriculture. The raw material undergoes strict incoming quality inspection before processing begins.
Depending on the target fraction, the extraction process utilizes solvent extraction, centrifugation, membrane filtration, and spray-drying technologies to isolate and concentrate specific bioactive components. Each production batch is processed under tightly controlled manufacturing conditions to preserve bioactivity, minimize oxidative degradation, and ensure consistent standardization of active compounds.
All soybean extract products are manufactured in a GMP-compliant facility certified under HACCP, ISO 22000, and ISO 9001 standards, with additional Kosher, Halal, and FDA compliance certifications to support global market access.
Product Specifications & Technical Details
Soy Isoflavones 20% & 40%
Soy isoflavones are naturally occurring polyphenolic compounds classified as phytoestrogens — plant-derived molecules that structurally resemble endogenous estrogens and interact with estrogen receptors in the body. The primary isoflavone components found in soy include daidzin, glycitin, genistin, daidzein, glycitein, and genistein, each contributing distinct biological activities.
Appearance: Light yellow-brown fine powder
Assay Method: HPLC
Specifications Available: 20% and 40% total isoflavones
Key Functional Properties:
- Supports regulation of cholesterol metabolism and cardiovascular health
- Inhibits free radical production through antioxidant mechanisms
- Promotes bone mineral density, making it relevant for osteoporosis prevention research
- Associated with reduced risk profiles in hormone-related conditions, including breast and prostate health studies
Soy isoflavones are widely formulated into women's health supplements, menopause support products, bone health formulations, cardiovascular nutraceuticals, and functional food applications.
Soybean Lecithin PC 98%
Soybean lecithin phosphatidylcholine (PC) 98% is a highly purified phospholipid fraction derived from soybean through advanced solvent extraction and centrifugation processes. With a phosphatidylcholine content of 20%–25%, this grade is specifically valued for applications requiring a high-purity lipid carrier and functional nutrient source.
Appearance: Light yellow fine powder
Phosphatidylcholine Content: 20%–25%
Extraction Method: Solvent extraction + centrifugation
Key Functional Properties:
- Exhibits notable antioxidant and anti-aging activity, making it suitable for both nutraceutical and cosmetic formulations
- Supports healthy blood lipid profiles and lipid metabolism
- Demonstrates hepatoprotective properties, supporting liver cell membrane integrity
- Promotes vascular health and arterial flexibility
Soybean lecithin PC 98% is widely used as an emulsifier, liposome-forming agent, and active ingredient in dietary supplements, functional foods, skincare formulations, and pharmaceutical drug delivery systems. Its amphiphilic nature makes it an especially versatile ingredient in lipid-based formulation systems.
Phosphatidylserine (PS) 20%, 50%, 70%
Phosphatidylserine is an essential phospholipid and a critical structural component of cell membranes, particularly abundant in neural tissue. It plays a fundamental role in maintaining cellular fluidity, signal transduction, and neurotransmitter synthesis. Our phosphatidylserine is derived from soybean, providing a plant-based and widely accepted alternative to earlier bovine-sourced PS.
Appearance: Light yellow powder across all grades
Solubility: Soluble in most non-polar solvents; insoluble in anhydrous acetone
Specifications Available: PS 20%, PS 50%, PS 70%
Key Functional Properties:
- Supports cognitive function and memory retention, particularly relevant for aging populations
- Enhances cerebral blood flow, improving nutrient and oxygen delivery to brain tissue
- Modulates the hypothalamic-pituitary-adrenal (HPA) axis, contributing to cortisol regulation and stress reduction
- Supports healthy sleep architecture and mood balance
Phosphatidylserine is one of the most clinically recognized cognitive health ingredients in the nutraceutical industry. It is formulated into nootropic supplements, brain health products, sports nutrition for stress and recovery management, and senior health formulations.
