Analysis of fat content by direct method (Direct extraction method) is a method of direct extraction with organic solvents, various. In General, a component of fat in the diet are compounds extracted by different solvents such as ether, petroleum ether and thathin ether, which is a non-polar solvents (Non polar solvent) extracts have called the "Crude fat" is an independent lipid (Free lipid) that is found.In the diet, but if doing extraction with alcohol part extracted, there will be other components attached to the fat contaminated with. If you want to get all the lipid extract in food must make hydrogen lies food samples with acid or alkali light. They included with the lipid compounds, such as proteins, carbohydrates, hydrocarbons will be closed as an independent cause lies extraction. How to perform a brief analysis follows.
