Although chemical compositions and analytical methods still play an important role in the definition of DF, physiological activity has also been taken into consideration. Decades of scientific research have initiated the expansion of the term DF to include indigestible oligosaccharides with their DP between 3 and 9; hence responding to the positive health benefits of DF as well as fulfilling the needs in food labeling regulations. Green leafy vegetables like spinach, lettuce, etc. each fibre is a single elongated cell that is flat twisted and ribbon like with a wide inner hollow (lumen). The term ‘dietary fibre’ (DF) was first introduced in 1950s, referring to plant cell wall materials; later it was used to describe a class of plant-originated polysaccharides, which cannot be digested and absorbed in the gastrointestinal tract (van der Kamp, 2004). Our dietary fiber range includes products suitable for use with all mainstream methods of dietary fiber analysis, recognising the 2009 Codex definition of total dietary fiber and methods designed for use with earlier definitions.
