A method and an apparatus for making a simple sugar solution from a liquid solution including at least one compound sugar by performing hydrolysis in the presence of a heterogeneous catalyst. The method comprises contacting the hydrolysis reaction medium with at least one microporous solid adsorbent compound selected for compatibility with the hydrolysis and catalysis conditions and for selectively adsorbing by-products other than simple sugars under the hydrolysis reaction conditions. A pure, colourless, food-grade simple sugar solution is achieved.
L'invention concerne un procédé et une installation de fabrication d'une solution de sucres simples à partir d'une solution liquide comprenant au moins un sucre composé, par hydrolyse en présence d'un catalyseur hétérogène. Le procédé consiste à mettre le milieu réactionnel de l'hydrolyse au contact d'au moins un composé adsorbant solide microporeux choisi pour être compatible avec les conditions d'hydrolyse et de catalyse et pour adsorber sélectivement les sous-produits autres que les sucres simples dans les conditions réactionnelles de l'hydrolyse. On obtient une solution de sucres simples pure et incolore, de qualité alimentaire.
