Fish oil among plant and animal extracts is rich in DHA
components and obtains high-purity DHA fractions in the food and
pharmaceutical industries. The purification of DHA&EPA is required, which relies on the separation of components
achieved by the difference in the activity of different components
under high vacuum conditions.
Purification of DHA&EPA is a type of short-path
vacuum distillation, characterized by extremely low vacuum
pressure. It’s considered the safest mode of separation and
purifies thermally unstable molecules and related compounds with
low volatility and elevated boiling point.
