Non-starch polysaccharides (NSP) Plant cell-wall NSP Other NSP Many different types of polysaccharides Main constituents arabinose, xylose, mannose, galactose, glucose, uronic acids Many types of constituents Escape digestion in the small intestine and are fermented to different extents Encapsulate and slow absorption of nutrients. Good marker for naturally fiber-rich diets for which health benefits have been shown Food additives. Minor components of the human diet. The amounts added to foods are known and regulated... 

A more precise analytical method permits measurement of the specific polysaccharides other than starch (section 4.2.1.6) that are the main constituents of dietary fibre the results of such analysis are quoted as non-starch polysaccharides (nsp).

Enzymes have been used for more than 20 years in poultry feed, mainly to improve the digestibility of cereals with high soiuble non-starch-polysaccharide (NSP) levels, such as wheat, barley, oats and rye [159, 160], It is well established that the inclusion of cell wall hydrolases in wheat, barley and rye-based diets of single-stomach animals, improves the efficiency of feed utilization, enhances growth and contributes to a better use of low-cost feed ingredients [161, 162], Several studies on the potential application of CBMs for animals feeding are available [163,164]. 

ADF = acid-detergent fibre, CF = crude fibre, NDF = neutrai-detergent fibre, NSP = non-starch polysaccharide. 

Dietary fibre was defined by Hugh TroweU as the plant polysaccharides and lignin which are resistant to hydrolysis by the digestive enzymes of humans . This definition lacks chemical precision, because non-flbrous pectins and gums are also present. The term nonstarch polysaccharide (NSP) is often preferred, although the term dietary fibre still persists. Unfortunately, NSP is also not satisfactory since some starch, known as resistant or par-...
