1-Kestose and method of producing the same |
摘要 |
The present invention relates to 1-kestose, especially crystals which is a fructooligosaccharide, and it is an object of the present invention to provide high-purity 1-kestose having no hygroscopicity and a method of producing it. Methanol is added to an aqueous solution containing as a main ingredient 1-kestose with a purity of 80% or more, and the mixture is then dried. Methanol is further added to the mixture to obtain 1-kestose crystals with a purity of 90% or more. An aqueous solution with a purity of 70% or more is concentrated, and 1-kestose microcrystals are added to the concentrate obtained to separate 1-kestose crystals with a purity of 94 to 99.9%. <IMAGE> |
