- Mid-to-High Concentration · Food-Grade Omega-3
Clear & Safe Omega-3,
engineered for purity & clarity
Zhejiang Norbidar Biomedicine produces food-grade EPA/DHA fish oil concentrates from 65% to 88%
— nearly colorless, physically separated, and free of fishy odor — via our proprietary NBD multi-stage distillation process.
A specification for every formulation
Ethyl ester (EE) Omega-3 concentrates in blended, EPA-rich, and DHA-rich profiles — from 65% to 88% EPA+DHA.

The NBD process
A multi-combined, high-efficiency continuous distillation that reaches mid-to-high concentrations other processes struggle to achieve.
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.
70–88% DHA+EPA
Conventional processes face a hard ceiling:
- Molecular distillation — typically only 30–60%
- Urea inclusion — food-incompatible, ethyl carbamate risk
- SFE / SFC / preparative LC — high cost, toxic solvents
- Rectification — isomerization, polymerization, coking
Five advantages, one clear standard
Our mid-to-high concentration fish oil reaches a new purity level, with Gardner color ≤ 2 and a nearly colorless appearance.
Light in color
Gardner ≤ 2, nearly colorless appearance.
Physical separation
Pure distillation — no solvents, no residues.
Ultra-low impurity
Controlled down to ≤ 0.5% for cleaner oil.
No fishy smell
Almost odorless for superior sensory profile.
