<p>A method for preparing a mixture of fructose, glucose and compounds of the general formula GFn, wherein G is glucose and F is fructose and n is an integer. The mixture is recovered from plant tubers or roots by means of a method which does not involve any chemical modification of the components of the mixture. A juice or syrup comprising fructose, glucose, sucrose and oligosaccharides is subjected at one or more suitable steps to a physical separation process to reduce the amount of fructose, glucosse and sucrose. The physical separation may be carried out by chromatography or nanofiltration or both. The mixture is suitable for use in foodstuffs and beverages for human beings and animals.</p> |
