NUTRIOSE® soluble dietary fibre granted prebiotic effect health claim in Korea
Roquette Korea obtained Health Functional Ingredients approval for its soluble dietary fibre NUTRIOSE® at the end of February 2011. This was thanks to NUTRIOSE® being certified for its prebiotic effect by the Korea Food and Drug Administration (KDFA).
The approval means NUTRIOSE® can be marketed in the Korean market as a “functional ingredient that may proliferate intestinal beneficial bacteria and inhibit harmful bacteria”.
NUTRIOSE® has been used as a beneficial ingredient in various applications – for instance, in yoghurt – since it was introduced in Korea in 2005. With the availability of a great deal of scientific research conducted by Roquette’s Nutrition Technical Team into the benefits of NUTRIOSE® – like its prebiotic effect – Roquette Korea started to assemble the documentation necessary to obtain approval of NUTRIOSE® as a functional ingredient. Backed up with support from members of Roquette worldwide, data on the identification, stability, safety and scientific substantiation were in due course submitted to KFDA, with eventual success.
Prebiotic effect of NUTRIOSE®
NUTRIOSE®meets the necessary and sufficient conditions for the prebiotic effect: (1) an increase in “beneficial bacteria” and/or a decrease in “harmful bacteria”; (2) a decrease in intestinal pH; (3) production of short chain fatty acids (SCFAs); and (4) changes in bacterial enzyme concentrations. NUTRIOSE® induced an increase of the colonic saccharolytic flora and a decrease in potentially harmful Clostridium perfringens in human faeces and a decrease in the faecal pH of human volunteers (Pasman et al., 2006). It also increased production of short chain fatty acids (SCFAs) in rats (Roberfroid and Slavin, 2001) and changes in faecal bacterial enzyme concentration (Van den Heuvel et al., 2004; Pasman et al., 2006).
