Features: SPECIAL FEATURE: Changing Methods for the Measurement of Dietary Fiber

In its simplest terms, dietary fiber content in a sample is measured in the laboratory by what is called an enzymatic-gravimetric method. After defatting, a food sample is treated with enzymes that mimic the digestive process in the human small intestine. Digestible carbohydrates are broken down into simple sugars and removed from the sample by precipitation using ethanol followed by filtration.
