Conclusions & recommendations fatty acids

Current assessment X Fatty acids in food products can be analyzed by many different methods using various analytical steps including or excluding a preliminary fat extraction. X Most of these methods have been developed a long time ago, updated regularly and harmonized, but often have to much freedom/lack of guidance.
