Fish oil is quite literally on everyone‘s lips. No other food supplement causes such a furor throughout the world. The reason is essentially the health-promoting effect of omega-3 fatty acids. According to scientific studies, fish oil is not only able to prevent cardiovascular disease, but also positively counteract Alzheimer‘s disease and other diseases in the dementia family.
However, before fish oil can be processed into ready-to-eat fish oil capsules, the fish oil obtained by the pressing process has to undergo a process of refining. Chemical refining with separators from GEA Westfalia Separator Group reliably removes unwanted substances from the fish oil.
Fish oil occurs either as a by-product of fishery or is produced specifically from industrial fish or from fish waste. The steeply rising demand for fish oil as a food supplement has now boosted the specific production of fish oil worldwide. To optimize fish oil for human consumption, it goes through a refining process to remove unwanted substances.
Chemical refining has proved itself in this context, neutralizing unwanted fatty acids and separating them off as soapstock using separators from GEA Westfalia Separator Group. Another separator is used after the refined fish oil has been washed. It removes the wash water from the oil phase, the oil is then vacuum-dried and can be processed further by the industry.
