How do you calculate the mass fraction of fatty acids?
Calculate the mass fraction of all fatty acids included in a group or in a class of fatty acids by the simple addition of individual fatty acids results corresponding to each class or group (expressed in grams fatty acids (FA) per 100 g product):
How are fatty acids extracted from food?
Fat and fatty acids are extracted from food by hydrolytic method. Fat is extracted into ether, then methylated to fatty acid methyl esters (FAMEs). FAMEs are quantitatively measured by gas chromatography. Add internal standard, ethanol and 8.3 M HCl. Remove flasks from water bath. Cool to room temperature. Add ethanol, Ether and shake.
What fatty acids should be in a fatty acid test?
fatty acids should be better than 0.05 g/100 g respectively. Availability of FAME standards for calibration is crucial to this test method. Insufficient FAME standards would underestimate the level of saturated fat and trans fat.
How do you measure fatty acid in milk powder?
Note: For fatty acid analysis on fat extracted from foods, the same amount of fat is required (about 50 mg). For milk powder or infant formula powder, add 2.0 mL water using a micropipet. Close the tube, and then dissolve gently using a vortex mixer. Wait for 15 min at room temperature.
