About Norbidar
Zhejiang Norbidar Biomedicine Co., Ltd. is a manufacturer dedicated to mid-to-high concentration, food-grade Omega-3 fatty acids. We produce food-grade EPA/DHA fish oil concentrates from 65% to 88% — nearly colorless, physically separated and free of fishy odor.
The company continues a technical lineage that began in 2018 with Ropeedar (Zhejiang) Biological Technology Co., Ltd., producing fumaric acid and antioxidants. Today, with achievements accumulated from 2012 to 2026, Norbidar concentrates that heritage into a single focused mission: making high-concentration fish oil that is genuinely clean, safe and food-grade.
- Enterprise History
Achievements from 2012 to 2026
From fumaric acid and antioxidants to high-purity Omega-3
— a steady build from process capability into a dedicated Omega-3 platform.
2018
Founded Ropeedar (Zhejiang) Biological Technology Co., Ltd.
Producing fumaric acid and antioxidants — the technical and manufacturing foundation the group was built on.
2024
Zhejiang Norbidar Biomedicine Co., Ltd. — under construction
A new site purpose-built to pharmaceutical fine chemical standards for mid-to-high concentration Omega-3 production.
2026
High-Purity Omega-3 Fatty Acid Project — put into production
Food-grade EPA/DHA concentrates from 65% to 88% via the proprietary NBD multi-stage distillation process.

- NBD innovative technology
The NBD process
A multi-combined, high-efficiency continuous distillation that reaches mid-to-high concentrations other processes struggle to achieve.
- Conventional process
Multi-step, with a hard ceiling
Feedstock DHA+EPA
25–30%
8-stage molecular distillation
50–60%
Urea inclusion & other processes
65–88%
Food-safe ceiling
50–60%
VS
- NBD process
One integrated continuous train
Feedstock DHA+EPA
20–30%
Multi-combined high-efficiency continuous distillation
70–88%
Food-grade result
70–88%
High-efficiency distillation
Multi-combined continuous distillation delivers DHA+EPA up to 70–88% — beyond typical molecular distillation (30–60%).
Full component separation
EPA or DHA can each reach 88%, with the counterpart controlled below 0.1%.
Gentle, food-grade, safe
Physical separation, no urea, no toxic methanol — no ethyl carbamate, no cis-trans isomerization.
- Quality System
Food-grade safety, made verifiable
Quality at Norbidar is a property of the process, not an inspection at the end.
Physical separation and controlled operating conditions are supported by batch-level testing and documentation.
Food-grade by design
No urea, no toxic methanol — physical separation only, so there is no ethyl carbamate and no cis-trans isomerization.
- Physical separation only
- No solvent residues
In-house analytics
Assay of EPA/DHA and full fatty-acid profile, together with color, oxidation and contaminant testing on every batch.
- EPA/DHA assay
- Gardner color ≤ 2
- Peroxide & anisidine value
- Heavy metals, PCB, dioxin screening
Traceability & documentation
Batch-level records from raw fish oil intake through to finished concentrate, with documents issued per shipment.
- Batch certificate of analysis
- Specification sheet
- Safety data sheet
Standards alignment
The site is built to pharmaceutical fine chemical standards, with clean-area and utility design appropriate for food-grade operations.
- Pharmaceutical fine chemical standards
- Segregated Class A storage
- Central process control
- Certification status and specific test limits are confirmed in the specification sheet and batch certificate of analysis issued for each product and shipment.
- What we stand for
Dedicated to serving every client
Four commitments that shape how we build, test and supply our Omega-3 concentrates.
Purity you can measure
Gardner color ≤ 2 and impurity controlled to ≤ 0.5% — cleanliness made verifiable, batch after batch.
Sensory quality
Almost odourless and nearly colorless oil, so it will not compromise the taste or appearance of your finished product.
Process depth
Continuous distillation engineered for 70–88% EPA+DHA, with full separation of EPA and DHA monomers.
Supply at scale
72,000 ㎡ of site with 10,000 tons of annual fish oil processing capacity behind every commitment.
