Of these type I methods, AACC International Approved Method 32-45.01 (AOAC method 2009.01) is the only procedure that measures all of the dietary fiber components as defined by Codex Alimentarius. The application of the Hellendoorn enzymatic-gravimetric method showed similar values of unavailable carbohydrate for both varieties; however, these values (21.6%) were higher than those previously reported for food grain legumes in the literature using the same method. The determination of soluble dietary fibre (SDF) yielded insignificant . Some known methods of extracting fiber from plant sources include dry processing, wet processing, chemical, gravimetric, enzymatic, physical, microbial or a combination of these methods.These methods are all enzymatic/gravimetric methods and the official status of each is summarised in Table 1 and acronyms are listed in Table 2. Figure 1. A schematic representation of the Prosky method (AOAC Method 985.29) for total dietary fiber determination. Concurrently, in the UK, Englyst and colleagues8,9), extended
The enzymatic-gravimetric method of Prosky et al (1985), officially known as AOAC method 985.29 (AOAC 1990), has been adopted by government agencies in many countries for routine nutrient labeling analyses because it is simple and rather inexpensive. However, there is some concern that the values forMain steps of the original and modified enzymatic-gravimetric AOAC methods AOAC original Prosky et al. (1988) AOAC modified Lee et al.

2.1 First Definition and Enzymatic Methods. In the middle of the twentieth century, the “dietary fiber” concept was first mentioned by Hipsley when he found a correlation between the lack of DF and pregnancy toxemia.The compounds included in Hipsley’s concept included lignin, cellulose and the hemicelluloses, defined as a non-digestible group of compounds that form .
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 .
The application of the Hellendoorn enzymatic-gravimetric method showed similar values of unavailable carbohydrate for both varieties; however, these values (21.6%) were higher than those previously reported for food grain legumes in the literature using the same method.
