Enzymatic-gravimetric methods. In the early 1980s, a enzymatic-gravimetric method was developed in which the sum of soluble and insoluble polysaccharides and lignin were measured as a unit and considered to be total dietary fibre (TDF). That method is detailed in section 45.4.07 of the AOAC International Official Methods of Analysis (45).
The method that evolved was AOAC Official Method 985.29 ‘Total Dietary Fiber in Foods; Enzymatic-Gravimetric Method’ 4, 5. Subsequently, the method was extended to allow measurement of total, soluble and insoluble dietary fibre in foods (AOAC Official Method 991.43) 6 , and various other modified methods for fibre determination have been . The IDF, SDF, and TDF were measured in date fruits using the enzymatic gravimetric method AOAC 991.43 in the ANKOM dietary fibre analyser, with and without enzymatic digestion.

Enzymatic–gravimetric methods have been recommended to determine dietary fiber. Recently in Brazil, the method 985.29 of AOAC (1990) was adopted for fiber levels notification on the label of packed food products (Brasil, 1998).Several problems as to the performance of these modifications of the method have been recorded (Jeraci and Van Soest, .

In 1985 the Association of Official Analytical Chemists (AOAC) adopted an enzymatic-gravimetric method, in which samples are subjected to serial digestion with amylase, amyloglucosidase, and protease, followed by isolation and gravimetric measurement of the residue as fiber (EGF). This method was first accepted in 1994 by the U.S. Food and Drug .A simplified enzymatic-gravimetric method for total dietary fiber (TDF) determination has been published and used in the Food Composition Laboratory of the U.S. Department of Agriculture since 1988.
