ABSTRACT: Dietary Fiber (DF) is a plant bioactive
compound, mainly a mixture of complex organic soluble and non-soluble polysaccharides
that is non-digestible and less hydrophobic. This dietary fiber is one of nutritional
supplements that demonstrated to have impact on
human and animal health. Chemical structures, sources, classification, methods of
analysis and therapeutic functions of DF are under investigation
by researchers for diseases prevention and enhancing immune response.
Dietary Fiber (DF) is diverse organic chemicals with higher molecular weight (HMW)
over 10 DP and lower molecular weight of lower under 10 DP and can be classified
generally by their solubility, viscosity, and fermentability. Dietary fiber is non-digestible
by enteric enzymes and passes through small intestine into the colon intake where
is fermented by enteric microbial biomass into
beneficial metabolites and short chains fatty acids. Other health benefits from
the acceptable daily intake such as adsorption of bile salts, polyphenols, and
minerals. In addition to, influence gastrointestinal tract physiology where it
has high water holding capacity and viscosity resulted in feeling satiety,
alternate digestive enzymes activity, improved gastric emptying, and increase
healthy microbial biomass in the colon.
