What does NSP fibre stand for?
non-starch polysaccharides
Dietary fibre is often referred to as non-starch polysaccharides (NSP) fibre or as AOAC fibre. NSP fibre only includes polysaccharides of the plant cell wall components characteristic of plant foods, such as wholegrain cereals, fruits and vegetables ( BNF website , FAO/WHO 2003 , pdf).
What is enzymatic-gravimetric?
In the early 1980s, a enzymatic-gravimetric method was developed in which the sum of soluble and insoluble polysaccharides and lignin were measured as a unit and considered to be total dietary fibre (TDF). The procedure was later extended to the determination of insoluble dietary fibre (IDF) (32.1.
What is AOAC fibre?
AOAC fibre comprises of the total amount of non-digestible polysaccharides, and includes e.g. lignin and resistant starches, measured with a set of methods developed by the Association of Analytical Chemists (AOAC) ( BNF website ). In general, figures for AOAC fibre are higher than NSP fibre.
What is Englyst method?
The analytical procedure known as the Englyst method determines NSP after enzymatic removal of starch, precipitation of NSP, followed by acid hydrolysis and measurement of the released constituent sugars. Its principle is that in-vitro RS is defined as that starch which is not hydrolyzed by incubation with a-amylase.
