acid hydrolysis method fat
What is the acid digestion method for fat?
For foodstuffs, the most commonly used method for determining the total fat content is extraction using acid digestion, i.e. the Weibull-Stoldt/Weibull-Berntrop method.
The sample is heated up with hydrochloric acid in order to digest proteins and release the bound lipids.
