Yellow brewers' grits ground to different particle sizes were extracted from 2 to 16 hr. with pentane-hexane, diethyl ether, or carbon tetrachloride. For comparative purposes, fat content of the grits was determined also by acid hydrolysis and by an extraction-transesterification procedure wherein the extract was analyzed by gas-liquid chromatography. Particle size strongly influenced the reported fat content regardless of method of analysis or extraction solvent used. Standardization of the grinding and analytical procedure would provide a basis for direct comparison of reported fat contents of brewers' grits.
