Abstract
The optimal conditions for the measurement of free fat in milk powder were determined in samples and fat-free milk powder to which defined amounts of fat were added.
It was found that approximately 90% of free fat could be extracted within a short time and under moderate conditions using carbon tetrachloride as a solvent. Experimental conditions were also found to be adequate for the measurement of free fat from fat-free milk powder.
In addition, n-hexane was also found to be suitable for use as a solvent, which is preferable given that carbon tetrachloride is harmful to humans and the environment.
