Our production infrastructure spans three dedicated, high-capacity facilities specializing in plant-based extraction, certified bee products, and customized animal-derived derivatives.
Independent GMP processing lines for herbal, bee, and animal-derived extraction.
Fully compliant with GMP, ISO, HACCP, ORGANIC, FDA, HALAL, and KOSHER guidelines.
Leading research in anti-aging, longevity molecules, and neuroprotective compounds.
An in-depth chemical and economic analysis of Olea europaea's rise in global therapeutic and functional food sectors.
Modern clinical studies are raising demand for high-strength Oleuropein (10% to 80%) and Hydroxytyrosol. Pharmaceutical companies are replacing raw leaf powders with standardized chemical fractions to ensure stable dosing in metabolic wellness and cardiovascular health supplements.
Due to the push for clean labels, commercial bakeries, oil mills, and meat processors are using fat-soluble olive extracts as natural antioxidants. This natural alternative successfully replaces synthetic options like BHT, BHA, and TBHQ, helping protect products from lipid oxidation.
Thanks to their ability to fight free radicals, Hydroxytyrosol and Oleuropein are becoming key ingredients in anti-aging creams and sunscreens. Their biological activity helps soothe skin redness, minimize UV damage, and support natural collagen levels.
The global market is shifting focus from basic herbal powders toward highly purified, bioavailable isolates. Regulatory bodies in Europe (EFSA) and North America (FDA) have acknowledged the heart health benefits of olive oil polyphenols. This recognition has driven raw material buyers to demand detailed chemical profiling, strict control of minor compounds, and absolute transparency regarding geographic origins.
At TRB, we address these evolving market needs by leveraging advanced membrane filtration and low-temperature counter-current extraction systems. This ensures the native molecular structures of Olea europaea are preserved without utilizing aggressive chlorinated solvents, delivering a clean, pesticide-free ingredient ready for the global stage.
For global purchasing managers, sourcing olive extracts requires careful attention to active assays, impurity profiles, and physical properties. Nanjing Tong Rui Bio-Tech (TRB) guarantees consistency across every batch, backed by our strict raw material validation processes.
We supply standardized parameters designed to integrate smoothly into dietary supplements, functional foods, and cosmetics:
| Active Molecule / Parameter | Standard Specification | Assay Method |
|---|---|---|
| Oleuropein | 10%, 20%, 40%, 60%, 80% | HPLC (High-Performance Liquid Chromatography) |
| Hydroxytyrosol | 5%, 10%, 20% | HPLC |
| Heavy Metals | < 10 ppm (Pb < 2.0ppm, As < 1.0ppm, Cd < 0.5ppm) | ICP-MS (Inductively Coupled Plasma Mass Spectrometry) |
| Pesticide Residues | Compliant with EP / USP limits | GC-MS / LC-MS-MS |
| Microbiological Profile | Total Plate Count < 1,000 cfu/g; Yeast & Mold < 100 cfu/g | USP / Standard Plate Count |
| Solvent Residues | Ethanol Only < 5,000 ppm (Methanol Free) | Headspace GC |
How TRB addresses supply chain risks, customization requirements, and formulation challenges for large-scale operations.
We provide tailormade particle sizing (fine mesh for tableting or granular forms for direct compression) alongside custom carrier systems (like maltodextrin-free options) to meet clean-label requirements.
Our raw material sourcing network guarantees a steady inventory, neutralizing market fluctuations caused by crop disease, seasonal variations, or geopolitical tensions in olive-growing regions.
Every shipment comes with detailed, auditable documentation, including Certificates of Analysis (COA), Allergen Statements, Non-GMO Declarations, MSDS, and full botanical traceability records.
Developing next-generation active ingredients through sustainable engineering and green chemistry.
In recent years, TRB has focused on the research and development of Nootropics products, such as Brain Health Herb Extract, Anti-Aging Herb Extract, and Longevity Herb Extract, which have received excellent feedback from our customers.
Our research shows that polyphenols from olive leaf extracts work synergistically with adaptogenic and nootropic compounds. For instance, pairing Hydroxytyrosol with targeted cognitive enhancers helps support cellular energy and neuroprotection. This opens up new possibilities for advanced wellness and brain health formulations.
We are constantly refining our extraction technologies. By using water-based extraction and membrane separation, we eliminate harmful chemical residues, offering a cleaner profile that aligns with modern consumer expectations.
