Marine phospholipids

Marine phospholipids - A new generation of omega-3 lipids The recently built extraction capabilities to remove dioxin from fishmeal at TripleNine in Esbjerg, Denmark, will allow the factory to produce not only clean fishmeal and fish oils, but also a new generation of fishmeal-derived polar lipids, the so-called phospholipids

hat are phospholipids and what is the difference between marine phospholipids and marine oils? Phospholipids act as natural emulsifiers and as such facilitate and ease the digestion and absorption of fatty acids, cholesterol and other lipophilic nutrients. Marine phospholipids have many benefits over fish oils, as they are much more resistant to oxidation (rancidity), have much higher contents of the physiologically important long-chain polyunsaturated omega-3 fatty acids EPA and DHA, provide these fatty acids with much better bio availability and have a much broader spectrum of health benefits for both animals and humans. Compared with triglycerides (oils), marine phospholipids provide a highly synergistic approach to combining the positive effects of long-chain omega-3 fatty acids with excellent stability, perfect bioavailability and a much wider range of health benefits.

Aquaculture use The consumption of fish species for which there is a high consumer demand such as salmon, trout, sea bass and halibut is increasing. Due to the high demand and limited natu-

ral stocks, much effort is spent on developing fatty acids, it is necessary to cultivate the cost effective aquaculture methods for farmorganisms in the presence of enrichment ing such species.

phospholipids production facility

Production of marine phospholipids has started TripleNine Fish Protein has invested DDK 20 million (US$3.8 million) in establishing a plant that makes it possible to extract phospholipids from fishmeal and fish oil. It is built in connection

with the company’s dioxin extraction plant in Esbjerg. The new plant has started the production of marine phospholipids in August 2008 and TripleNine expects great market potential for this new product. First generation of the product will have a content of approximately 40 percent phospholipids and approximately 30 percent of EPA and DHA. The European Union and the Danish Ministry of Food, Agriculture and Fisheries have supported the project of marine phospholipids.

A new generation of omega-3 lipids with a broader spectrum of health benefits. - High DHA contents, preferably in easily digestible and highly bio available form for aquaculture use. - Numerous benefits on improving the immune response, better weight gain and physical conditions of land animals.
