A process is described for producing a syrup containing reducing sugars, of which at least 70% is fructose. The process comprises extracting the liquid material from an inulin-containing naturally-occurring material to obtain an inulin-containing liquid feedstock, adjust ing the pH of the inulin-containing liquid to about 3-5, continuously moving the said liquid through a confined tubular hydrolyzer to produce a hydrolyzate in fluid form containing monosaccharides as at least about 80 wt.% of the dissolved material therein, said reducing sugars containing at least 70 wt.% fructose, less than 20 wt.% disaccharides and trisaccharides and substantially no higher saccharides, subjecting the hydrolyzate to ion exclusion chromatography to separate ash therefrom an subjecting the hydrolyzate from ion exclusion to ion exchange to remove any remaining ash, as well as some disaccharides and proteins, the final product after ion exchange being a high fructose syrup in which at least 95 wt.% of the reducing sugars are monosaccharides, of which at least 70 wt.% is fructose, and less than 5 wt.% disaccharides. |
