A process for producing a cellooligosaccharide which comprises enzymatically decomposing in the presence of a cellulase a water-insoluble natural cellulosic substance which has an average degree of polymerization of 700 or lower and an average particle diameter of 100 ~m or smaller and in which the content of components soluble in diethyl ether is less than 1 mass%. Also provided is a process for cellooligosaccharide production which comprises enzymatically decomposing in the presence of a cellulase a water-insoluble natural cellulosic substance which has an average degree of polymerization of 700 or lower and in which the content of colloidal cellulose components is 10 mass% or higher and the content of components soluble in diethyl ether is less than 1 mass%.

Cette invention a trait à un procédé pour la production d~un cello-oligosaccharide comprenant une substance cellulosique naturelle insoluble dans l~eau subissant une décomposition enzymatique en présence d~une cellulase ayant un degré moyen de polymérisation de 700 ou moins et un diamètre moyen de particule de 100 µm ou moins et dans lequel la teneur en composants solubles dans l~éther diéthylique est inférieure à 1% par masse. Cette invention concerne également un procédé pour la production d~un cello-oligosaccharide comprenant une substance cellulosique naturelle insoluble dans l~eau subissant une décomposition enzymatique en présence d~une cellulase ayant un degré moyen de polymérisation de 700 ou moins et dans lequel la teneur en cellulose colloïdal est égale ou supérieure à 10% par masse et la teneur en composants solubles dans l'éther diéthylique est inférieure à 1 % par masse.
