Fructo-Oligosaccharide
FOS can be produced by degradation of inulin, or polyfructose, a polymer of D-fructose residues linked by β(2→1) bonds with a terminal α(1→2) linked D-glucose. Inulin can be degraded enzymatically or chemically to a mixture of oligosaccharides with the general structure Glu–Frun (abbrev. GFn) and Frum (Fm), with n and m ranging from 1 to 7. This process also occurs to some extent in nature, and these oligosaccharides can be found in a large number of plants, especially in Jerusalem artichoke, chicory and the blue agave plant. The main components of commercial products are kestose (GF2), nystose (GF3), fructosylnystose (GF4), bifurcose (GF3), inulobiose (F2), inulotriose (F3), and inulotetraose (F4).
The second class of FOS is prepared by the transfructosylation action of a β-fructosidase of Aspergillus niger or Aspergillus on sucrose. The resulting mixture has the general formula of GFn, with n ranging from 1 to 5. Contrary to the inulin-derived FOS, not only is there β(1→2) binding but other linkages do occur, however, in limited numbers.
Because of the configuration of their glycosidic bonds, fructooligosaccharides resist hydrolysis by salivary and intestinal digestive enzymes. In the colon they are fermented by anaerobic bacteria. In other words, they have a lower caloric value, while contributing to the dietary fiber fraction of the diet. Fructooligosaccharides are more soluble than inulins and are, therefore, sometimes used as an additive to yogurt and other (dairy) products. Fructooligosaccharides are used specially in combination with high-intensity artificial sweeteners, whose sweetness profile and aftertaste it improves.
Bailong is the leading production enterprise of Fructo-Oligosachharide Powder 95% (FOS), Isomalto-Oligosaccharide Powder (IMO), Xylo-Oligosaccharide Powder and syrup (XOS), Polydextrose Powder and syrup, Resistant Dextrin Powder and syrup, Allulose Crystal and syrup and Galacto-Oligosaccharide Powder and syrup (GOS) in China. Those products can replace sugar and be applied in healthy food, functional beverages, baby food etc.
