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.

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.

Dedicated to serving every client

Built to pharmaceutical fine chemical standards, the Norbidar site is designed for food-grade Omega-3 production at scale.

The NBD process

A multi-combined, high-efficiency continuous distillation that reaches mid-to-high concentrations other processes struggle to achieve.

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

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.

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.

In-house analytics

Assay of EPA/DHA and full fatty-acid profile, together with color, oxidation and contaminant testing on every batch.

Traceability & documentation

Batch-level records from raw fish oil intake through to finished concentrate, with documents issued per shipment.

Standards alignment

The site is built to pharmaceutical fine chemical standards, with clean-area and utility design appropriate for food-grade operations.

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.
