Translating complex plant active profiles into highly solubilized, bio-accessible solutions for international wellness brands.
Shenzhen Rubrum Biologics Co., Ltd. stands at the forefront of China's herbal extraction industry as an authoritative manufacturer and technology integrator. We dedicate ourselves entirely to the systematic research, technological development, raw material purification, and global supply of high-grade natural plant extracts. Our target applications cross various critical industry lines: premium infant nutrition, functional food formulations, pharmaceutical-grade dietary supplements, personal care items, and clinical cosmetics.
Leveraging a complete matrix of modern extraction lines and highly integrated production systems, our scientific teams address one of the industry's longest-standing issues: maintaining natural botanical bioactivity while securing absolute water-solubility. This dual capability allows raw ingredients to blend seamlessly into clear liquid matrices without sedimentation, phase separation, or off-flavor challenges.
We provide comprehensive OEM/ODM product pipelines. Whether you require customized standardized powder extracts, bulk liquids, bespoke dry ratios (10:1 to 100:1), or clean-label formulations, Shenzhen Rubrum Biologics equips you with market-validated ingredients backed by strict chemical and microbiological certification.
"Our core mission is to bridge raw natural potency with precision engineering. Through physical modification, particle engineering, and green extraction techniques, we ensure every batch of active compounds behaves flawlessly in aqueous solutions."
Analyzing the consumer demand for rapid absorption, clear formulations, and clean-label functional beverages.
Traditional herbal powders possess complex cell walls and crystalline structures that resist human digestive breakdown. Developing dynamic water-soluble formats significantly increases systemic cellular uptake, accelerating metabolic utilization and onset speed.
Functional beverages and cosmetic serums demand clear, non-turbid finishes. Our technological integration targets lipid-soluble molecules, adapting them through micro-emulsification or molecular encapsulation to prevent precipitation and cloudiness.
Concentrated phytochemical compounds like polyphenols and alkaloids carry intense bitter, astringent profiles. Our specialized processing embeds target materials, masking off-notes without using synthetic chemical blockers.
Why leading international brands choose Shenzhen Rubrum Biologics for cost efficiencies, scale, and high quality.
We manage direct agricultural partnerships and contract farming across diverse climatic regions of China. This guarantees that botanical species such as Danshen, Dandelion, and Epimedium are harvested at peak active compound content, free from environmental contaminants.
Located within Shenzhen’s high-tech industrial corridor, we combine biological engineering with advanced machinery integration. Our production units run adjacent to primary domestic shipping routes and global air freight hubs, reducing logistics overhead.
High-capacity extraction vessels paired with automated packing lines ensure lower processing costs per kilogram. We transfer these structural advantages straight to our global OEM/ODM partners, helping them optimize their product margins.
Our dry climate controlled storage spaces maintain multi-ton inventories of key raw botanicals. This protects your brand's supply chain from seasonal crop fluctuations, sudden market shortages, or unexpected international price hikes.
Understanding the mechanics and processing steps behind our custom water-soluble formulations.
Every botanical species undergo selective solvent extraction. We optimize critical extraction parameters—temperature, pressure, raw material ratios, and dwell time—using water or food-grade ethanol. This process selectively extracts the target phytochemicals while removing undesirable insoluble fibers, lipids, and waxes.
For hydrophobic compounds like curcuminoids, silymarin, or fatty acids, we apply advanced physical modification technologies. Utilizing high-shear homogenizers and food-grade carriers (such as cyclodextrins, gum acacia, or sunflower-derived phospholipids), we wrap active molecules in hydrophilic shells, allowing rapid dispersion in water.
The refined liquid complex undergoes rapid low-temperature spray drying under vacuum. This protects heat-sensitive active ingredients from thermal degradation. We control the particle size distribution (PSD) and use fluid-bed agglomeration to produce instant-dissolve, dust-free granules that melt instantly upon contact with water.
Rigorous analytical verification and certification systems designed to clear international regulatory hurdles.
Modern international sourcing managers face a complex web of regulatory barriers. From FDA NDI filings, EU Novel Food authorizations, to Prop 65 compliance, sourcing botanical ingredients demands high transparency. Shenzhen Rubrum Biologics operates on a foundation of absolute reliability and document traceability.
Every batch of our water-soluble botanical extracts undergoes strict testing. We issue a comprehensive Certificate of Analysis (CoA) containing detailed testing methods, active compound standardization (HPLC/UV/GC), heavy metal thresholds, residual solvent analyses, and microbiological counts.
| Test Item | Testing Method | Standard Specifications |
|---|---|---|
| Active Compound Assay | HPLC-DAD / UV-Vis | Fully Standardized (e.g., Lcariin 10%-98%) |
| Heavy Metals (Pb, As, Hg, Cd) | ICP-MS | ≤ 10.0 ppm (individual limits below USP thresholds) |
| Pesticide Residues | GC-MS/MS | Meets European Pharmacopoeia (EP) & FDA Regulations |
| Solvent Residues | Headspace GC | Ethanol / Water only (≤ 5000 ppm) |
| Microbiological Profile | Plate Count | Total Count < 1,000 cfu/g; Yeast/Mold < 100 cfu/g |
Our production facilities and manufacturing processes are regularly audited by third-party certification bodies to guarantee consistent quality. We hold credentials including:
By establishing relationships with global testing networks like Eurofins and SGS, we facilitate verification processes before shipping, accelerating port customs clearance.
From clean-label functional beverages to active topical formulations, discover where our ingredients shine.
Our soluble extracts (such as Dandelion, Danshen, or Oyster Mushroom) are optimized for tablet compression, hard shell encapsulation, and liquid fill systems. The uniform particle sizes prevent physical separation during manufacturing.
Designed to dissolve instantly in cold water without stirring. Ideal for modern stick pack formulas, energy drinks, tea formulations, and wellness shots. Complete clarity, zero precipitate, and balanced taste profiles.
Soluble botanical actives like Chamomile liquid and Oat extract with standardized Avenanthramides are engineered to blend smoothly with topical emulsion bases, creams, face masks, and clear personal care serums.
