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 .

This method extends the capabilities of the previously adopted AOAC Official Method 2009.01, Total Dietary Fiber in Foods, Enzymatic–Gravimetric– Liquid Chromatographic Method, applicable to plant material, foods, and food ingredients consistent with CODEX Definition 2009, including naturally occurring, isolated, modified, and synthetic .

Abstract. A method for the determination of total dietary fiber (TDF), as defined by the CODEX Alimentarius, was validated in foods. Based upon the principles of AOAC Official Methods SM 985.29, 991.43, 2001.03, and 2002.02, the method quantitates high- and low-molecular-weight dietary fiber (HMWDF and LMWDF, respectively).

(1992). The origins of these methods can be tracked back to the biochemical approach of measuring the indigestible residues in human foods introduced by The enzymatic-gravimetric methods are considered the most suitable for routine analysis of dietary fibers, but are ineffective for determining oligosaccharides with polymerization degree less than .

Organic matter digestibility (OMD) is of great importance, as it is the main factor determining the energy value of animal feed (de Boever et al., 1986; Beecher et al., 2015).In vivo determination of OMD of feeds is regarded as the reference value.
