Starting Materials: We employ two different supply chains, conventional defatted soybean meal (low-cost) and certified non-GMO soybeans with full planting records (export-grade). All raw materials are pre-screened to eliminate mouldy, heat damaged or aflatoxin tainted lots.

Grade Classification:

· Industrial Grade (20%-40%): Standard soybean meal for everyday supplements

· High-Purity Refined Grade (80%+): Select premium meal with verified low contaminant levels

· Non-GMO Traceability Grade: Independent production line preventing cross-contamination, ideal for European/American markets

Our darkish, dry warehousing prevents oxidation, whilst batch codes hyperlink every kilogram to reap place, processing date, and first-rate certificates.

Solubility Profile:

· Standard powder: Slightly soluble in cold water; readily dissolves in hot water, ethanol, and methanol

· Cyclodextrin-modified version: Rapid cold/hot water dispersion with clear, stable solutions

· Lipid systems: Moderate oil solubility; high concentrations require careful dispersion to prevent crystallization

Stability Features:

· Thermal Tolerance: Stable up to 65°C; prolonged exposure above 80°C causes oxidative degradation—process with temperature monitoring

· pH Range: Optimal stability between pH 4.0-7.5; strong acids/alkalis damage molecular structure

· Light Sensitivity: Dry powder remains stable when sealed and light-protected; aqueous solutions yellow under UV exposure

· Hygroscopicity: Higher purity grades attract moisture—vacuum-sealed aluminum foil packaging ensures 24-month shelf life unopened

Step 1: Raw Material Processing

Defatted soybean meal is air-screened for the elimination of contaminants and rancid-sized particles. Drying at low temperature regulates moisture content and mechanical milling to 20-30 mesh particle size maximises floor location for effective extraction.

Step 2: Ethanol Reflux Extraction.

The cloth is charged into sealed reactors and extracted in food-grade ethanol-water mixtures in 2–three cycles. Plate-and-frame filtration separates particles and collects all liquid extracts.

Step 3: Vacuum Concentration

The filtrates are concentrated via poor strain evaporation at < sixty five°c and the ethanol is reused to present crude extract paste.

Step 4: Resin Purification (Specification Driver)

Diluted extract is loaded onto macroporous resin columns. Water washing eliminates sugars, salts and proteins. Isoflavones are accumulated with the aid of gradient ethanol elution: 20%-40% grades in unmarried skip; 80%+ purity in multi-level series.

Step 5: Enzymatic Conversion (Optional for Aglycone Forms)

The purified glycoside answer is treated with β-glucosidase beneath regulated temperature/ph to convert the molecules into relatively absorbable aglycones. Warmth inactivates enzymes after response.

Step 6: Refining and Decolorising

That is observed by means of secondary awareness and removal of pigments with the aid of activated carbon reflux. Filtration produces a satisfactory liquid.

Step 7: Spray-drying

Atomise the extract into fine Soy isoflavones powder and dry it quickly under strict inlet/outlet air temperature control.

Step 8: Cyclodextrin Inclusion (Custom Water Soluble form)

The purified extract is complexed with β-cyclodextrin by high strain homogenisation and ultimately spray-dried.

Step 9: Milling & Homogenization

Product crushing 80-100 or 200 mesh homogeneity. 3D mixing assures uniform batch properties.

Step 10: Packaging Quality Confirmed

The vacuum packed aluminium foil bags cross into moisture-evidence drums. Earlier than discharge from the warehouse, full checking out for potency, heavy metals, aflatoxin and microorganisms is carried out.

Health Supplement Industry:

Create menopausal guide tablets containing 40-80mg day by day doses to reduce hot flashes, night time sweats, and temper swings. Bone fitness tablets contain isoflavones, that could assist save you osteoporosis with the aid of retaining calcium. Antioxidant mixes guard cellular structures from unfastened radical harm.

Functional Food & Beverage:

Increase the nutrients of soy milk, yoghurt and meal replacement powders by 0.1%-0.3% without altering the flavour. Micro-encapsulation avoids the harsh taste of protein shakes.

Cosmeceuticals Segment:

Add 0.5%-1% to your anti-aging lotions and serums. Genistein boosts collagen production and protects against UV-induced photoaging, enhancing skin suppleness and minimising wrinkles.

Core Benefits:

Phytoestrogens natural action • Lipid control and cardio protection • Boosting the immune system • A natural, hormone-free alternative to synthetic HRT.

We are committed to excellence and have an extensive certification portfolio that includes ISO9001, HALAL, NOP, EOS, KOSHER, cGMP, ISO22000, FSSC22000, and HACCP. Every batch undergoes stringent in-house testing for potency (HPLC), heavy metals (ICP-MS), and microbiology (following international limits).

Our results are verified by third party laboratories and we include a Certificate of Analysis with each of our shipments. Complete traceability documentation from seed source to final packaging gives audit-ready transparency. Quality worries? No worries, our replacement/refund policy has got you covered.

Standard Packing:

Inner: vacuum packed aluminium foil bags (light proof, oxygen barrier)

Outer: 25kg moisture-proof fibre drums with good seal.

Custom Choices:

1kg, 5kg, 10kg retail ready pouches; • Private Labelling • Blister containers of final dosage forms

Shipping Method:

The global logistics network covers express courier (small samples), air freight (urgent orders) and sea transport (bulk volumes). Our supply chain management provides safe and timely delivery with full export documentation (Phytosanitary Certificates, COA’s).

Q: Can I get soy isoflavones that are non-GMO?

A: We provide both conventional and certified Non-GMO. Full traceability evidence is provided for non-GMO products from certified soybean sources.

Q: What’s the difference between the specs?

A: For cheap daily supplementation, the 20%-40% glycoside versions are best. 80% high purity grades for intensified dosage in premium formulae. Aglycone variants have a better intestinal absorption for particular purposes.

Q: Do you test for contaminants?

A: Sure. All batches are tested for heavy metals, aflatoxins, pesticide residues and solvent purity according to EU and FDA food safety regulations. Third party reports available on request.

Q: Do you have a stable bulk supply?

A: We have tonnage-based inventory and annual contract manufacturing capabilities. Complete export documentation guarantees smooth international transactions.

Q: What do I do with this ingredient?

A: Mix powder with carrier (starch/lactose) in tiny portions before adding to main formulation. Do not use for long periods above 80°C. Store in sealed container in cool, dry, dark circumstances.
