bespoke Formulations for Powder, Tablet, Hard Capsule & Soft Capsule Formats ：We can develop a bespoke formulation for your application requirements.

Core Extraction Raw Materials: We source exclusively from first-harvest Lithocarpus spp. tender leaves harvested in spring. Old leaves, withered branches, moldy materials, and insect-damaged parts are strictly removed. Post-harvest, raw materials undergo rapid low-temperature drying (40–45℃) to prevent sunlight oxidation that degrades flavonoid content.

Grade Classification:

· High-Purity Refined Grade (98%): First-harvest tender buds undergo full heavy metal and pesticide residue screening before processing. This grade features low background impurities and is produced on independent lines to prevent cross-contamination—specifically designed for export markets.

· Traceable Export Grade: Complete planting, harvesting, and processing traceability with origin data available. Independent production lines ensure zero cross-contamination with conventional raw materials.

Trilobatin Powder (Standard): Slightly soluble in cold water, soluble in hot water, ethanol, methanol and acetone. Almost insoluble in vegetable oils. (Do not add to vegetable oils) Crystallising and dispersing poorly when introduced at high quantities immediately to oil phases.

Cyclodextrin-modified version: Easily soluble in both cold and hot water to provide homogenous transparent solutions that do not become murky or precipitate on standing – the choice for clear essences, oral liquids and cleared drinks.

Thermal Stability: Stable during vacuum drying at low temperature (≤65℃). Prolonged exposure to high heat might cause some deterioration.

Light & Oxygen Sensitivity: Vacuum packed in light resistant aluminum foil pouches to ensure glycoside integrity and prevent oxidation.

Step 1 – Raw Material Pretreatment Impurities are removed by manual and air sorting, then the material is dried with low temperature hot air (40-45℃). Materials are ground to 20 to 30 mesh to improve the contact area with the solvent.

Step 2 – Ethanol Reflux Extraction: Closed reactor extraction with food grade ethanol aqueous solution 2-3 times. Plate and frames filtration for solid-liquid separation.

Step 3 – Low-Temperature Concentration: Under negative pressure (<65℃), concentrate extract with ethanol recovery for recycling.

Step 4 - Macroporous resin purification: Diluted extract was placed onto columns of resin. Sugars, pigments and salts are washed by water. Trilobatin is enriched by ethanol gradient elution.

Step 5 – Recrystallization & Purification Specification 98%: Double recrystallization with activated carbon decolorization and two-stage resin purification can effectively eliminate flavonoid impurities and pigments, and the purity is constant and the color difference between batch is small.

Step 6 – Rinsing & Vacuum Drying: The crystals were washed with weak ethanol and filtered water, centrifuged for dehydration and vacuum dried in darkness (≤65℃) to avoid oxidation.

Step 7-Optional Cyclodextrin Modification: Mix high-purity trilobatin with β-cyclodextrin by high-pressure homogenization, spray dry to get cold-water-soluble modified powder.

Step 8 – Grinding & 3D Mixing: Grinding to required particle sizes and blending in 3D mixers to achieve homogenous content, color and particle dispersion.

Step 9 - Sealed Packaging & Testing: Vacuum packed in aluminium foil bags, secured in 25kg moisture resistant cardboard barrels. Heavy metals and microbial testing prior to storage , full content .

Metabolic Health Supplements: Supports modification of glucose metabolism for weight management tablets, capsules and meal replacement powders.

Whitening & Anti-Aging Cosmetics: With constant purity and uniform color, 98% Trilobatin Powder is the standard option for whitening essences, anti-aging serums and high-end skincare formulas.

Oral Care Products: A natural sweetener with bioactive qualities, perfect for chewable pills, lozenges and oral care supplements.

Functional Beverages: Offers natural sweetening and antioxidant advantages for health beverages, sports nutrition and clarifying beverages.

Certification Systems ISO9001, ISO22000, FSSC22000, HACCP, HALAL, KOSHER, cGMP, Non-GMO, Vegan

Testing Capabilities: Each batch is evaluated for purity, potency, heavy metals, pesticide residues and microbiological by UPLC, HPLC, ICP-MS and GC-MS.

Traceability: Complete documentation from the procurement of raw materials to the final product distribution provides complete transparency of the supply chain.

Third Party Validation: Independent laboratory testing results are available upon request.

Standard Packaging: 1 kg aluminum foil bags; 25 kg cartons; 25 kg fiber drums with moisture-proof liners.

Customized Options: Flexible packaging solutions available for specialized transportation and storage requirements.

Shipping Methods: Air freight and ocean freight options; worldwide supply capabilities with professional logistics support.

Q: Do you test raw materials for heavy metals and pesticide residues before processing?

A: Yeah. We utilize only recently picked fresh delicate leaves and do not use rotting, worm-eaten or damaged material. All source materials undergo tested for complete pesticide residue and heavy metals before feeding. Unqualified batches are rejected immediately.

Q: What’s the difference between 95%, 98% and 99% specifications?

A: 95% single recrystallization (inexpensive for basic skin care and meal replacements); 98% double recrystallization with decolorization (most common for oral supplements and whitening essences); 99% repeated gradient recrystallization and chromatographic purification (premium dietary formulations and pharmaceutical intermediates).

Q: Can I put regular trilobatin straight into oil-based creams?

A: Slightly soluble in vegetable oils. Crystallization may be caused by direct high dosage addition. Emulsifiers should be pre-dissolved in ethanol or propylene glycol to provide a uniform distribution into the oil phase.

Q: Do you have cyclodextrin modifications in water soluble forms?

Yes. Our β-cyclodextrin inclusion modified product is meant to dissolve quickly in cold and hot water to provide clear solutions. It is specifically developed for use in transparent essences, oral liquids and clarified beverage formulations.

Q: What is your minimum order quantity and lead time?

A: MOQ is adjustable as per specification. Standard lead time 10-15 days following order confirmation. For bespoke needs, please contact us at information@sxrebecca.com.
