Abstract
The invention concerns a process for production of L-arabionose in crystalline form. Starting material are extracted sugar beet pulp or other L-araban containing plant materials. These are heated in an autoclave as an aqueous suspension in the presence of Ca(OH).sub.2. The so obtained solution is chromatographed on a cationic exchanger in the Ca-form. The araban containing fraction is hydrolyzed after adding H.sub.2 SO.sub.4, neutralized and rechromatographed on a cationic exchanger in Ca-form. After concentrating the arabinose containing fractions L-arabinose is obtained in form of crystals by cooling crystallization.
