Omega 3: Concentration process
Vitaelin Nutraceutical's WINOmeg3complex is a natural choice. There are many studies proving the wide-range of benefits provided by omega-3. However not all omega 3s are the same. Vitaelin's Physician’s Health & Diet line of omega-3 supplement considered a pharmaceutical grade omega-3, filled with 88% omega-3 ethyl esters with a 60% concentration of EPA for maximum anti-inflamitory benefit, making WINomega3complex approximately three times more potent than most omega-3 supplements currently available.
Concentration processes...
The omega-3 fatty acids EPA and DHA have special characters compared to all other naturally occuring fatty acids in two ways: they have the longest carbon chain and they are the most unsaturated. This means that they have the largest number of double bonds in the chain. Both these properties are exploited in processes for making products with higher concentrations of omega-3.
Long chain fatty acids have lower volatility than short chain fatty acids thus being separable by distillation. But the boiling points are high. In order to avoid decomposition caused by high temperatures, the most common way of distillation is molecular distillation. This is true even if the separation is poorer than in ordinary distillation columns. The technique is characterized by the fact that the evaporation takes place from a heated thin film and that the distance from this evaporation zone to the cooled condenser is very short. In this way temperature strain to the product is minimized. By molecular distillation it is possible to increase the omega-3 content from 30 to 60%.
Urea complexation is a special crystallization technique that is not yet fully understood. It is based on the fact that when urea chrystallizes during cooling from a solution of fatty acids in a suitable solvent, the saturated and monounsaturated fatty acids are included in the crystals. As a result they are removed from the solution together with the crystals by filtration while the polyunsaturated fatty acids remain in solution. In this way it is possible to remove all saturated and monounsaturated fatty acids and increase the concentration of omega-3 fatty acids from a molecular distilled concentrate from 60 to more than 85%.
