This method involves a partial drying of a weighed sample prior to a Soxhlet extraction. The extracted fat is weighed and the fat content calculated. It is important that sand be incorporated with the sample before drying.What is the AOAC method for fat determination?
Gas Chromatography for Detection of Trans Fats
Methodology for Detection of Trans Fats: As per the Official Methods of Analysis, AOAC method 996.06 is used for the detection of trans fats in food samples by Gas chromatography. By using this method, the total trans fat content in the food samples can be detected.What is the standard method for fat estimation?
The “Soxhlet” method described here is recognised by the Association of Official Analytical Chemists (AOAC) as the standard method for crude fat analysis. In addition, some rapid instrumental methods are also approved by the AOAC.- The Gerber Method is a primary and historic chemical test to determine the fat content of substances, most commonly milk. The Gerber Method was developed and patented by Dr. Niklaus Gerber of Switzerland in 1891. In this method milk fat is separated from proteins by adding sulfuric acid (1.820-1.825 sp.
