Acetone–Water Mixtures for the Extraction and Rapid Estimation of Fats of Biological Materials, Particularly Fish Products

The variation of the efficiency of acetone as an extractant of fats from biological materials has been studied. The moisture content of the acetone was found to be the dominating factor. Refluxing time, as well as the ratio of solvent to sample, have been found to be of minor importance. A rapid, precise analytical method of fat determination based on these observations has been developed.
