Dietary fiber df is an important component of the human diet.

Total dietary fiber analysis of foods. The contents of dietary fiber in some foods are given table 5 jalili et al 2001. The gold standard method for the measurement of total dietary fibre is that of the association of official analytical chemists 2000. Based upon the principles of aoac official methods 985 29 991 43 2001 03 and 2002 02 the method quantitates water insoluble and water sol. Chemically fiber is formed by a special type of carbohydrates called starchy polysaccharides or pna which in most cases corresponds to the cell walls of plant foods.

From a viewpoint of food fiber is considered to those parts of plants that can not be digested by the human body.

The choice of analytical method depends therefore primarily on the purpose of the analytical work.

Although it is not hydrolyzed and absorbed in the upper gastrointestinal tract df can be fermented in the lower gastrointestinal tract and provides health benefits when consumed regularly latulippe et al 2013 the establishment of definitions and analytical methods able to quantify all the compounds included. This method is an update of aoac method 2009 01 also published as aacc method 32 45 01 for the determination of total dietary fiber in foods and food ingredients as defined by the codex alimentarius commission. Measurement of dietary fiber dietary fiber content in a sample is measured in the laboratory by what is called an enzymatic gravimetric method.
