Page/Page column 25-27, (2009/03/07)
In the technical field of Chemistry, encompassing products defined like FOS - fructooligosaccharides and applicable in food and or medical-pharmaceutical, veterinary and odontological industries, including the segment of supplements and functional foods, through the partial hydrolysis of inulins and similar fuctans till hydrossoluble FOS in the preferential range of DP - Degree of Polymerization from 2 to 18 or even more with reduced content of free fructose, using as catalysts for hydrolysis the citric and / or phosphoric acids as alternative to the classic hydrochloric or sulfuric acids and to the microbial enzymes, with the particularity that, through partial neutralization or simple dilution of the hydrolyzates, the catalysts now proposed, may either remain for the industrial and ulterior proposals or alternatively be removed by ion exchange resins or other means, being still possible that the citric or phosphoric acid may be conveniently diluted to the preferential range of pH 2.0 to 3.0 as moderate acidicity and the hydrolysis be carried out at moderate temperatures in the range from 75oC to 90oC in the range of preferential times from 5 to 30 minutes.
