    • Oligoglucosylfructosides wherein an oligoglucosylfructoside having a polymerization degree of 2 or 3 glucose units are recovered in a high purity from a feed solution additionally containing substantial amounts of higher- and lower-oligosaccharides by sequentially admitting predetermined volumes of the feed solution and water to the column of a strongly-acidic cation exchange resin in alkaline-earth metal form; sequentially separating the effluents from the column into the first fraction rich in the higher oligosaccharide, the second fraction rich in the higher oligosaccharide but highly contaiminated with the oligoglucosylfructoside, the first fraction rich in the oligoglucosylfructoside, the fourth fraction rich in the oligoglucosylfructoside but highly contaminated with the lower oligosaccharide, and the fifth fraction rich in the lower oligosaccharide; and recovering the third fraction. The second- and fourth fractions can be admitted to the column so as to decrease the amount of elution water and also to recover the high-oligoglucosylfructoside fraction in a much higher concentration and recovery yield.

    • The invention provides a process for enabling the production of a particulate composition containing anhydrous crystalline ascorbic acid 2-glucoside that does not significantly cake even when the production yield of ascorbic acid 2-glucoside does not reach 35% by weight. The process for producing a particulate composition containing anhydrous crystalline ascorbic acid 2-glucoside, which comprises allowing a CGTase to act on a solution containing either liquefied starch or dextrin and L-ascorbic acid and then allowing a glucoamylase to act on the resulting solution to obtain a solution with an ascorbic acid 2-glucoside production yield of at least 27%, purifying the obtained solution to increase the ascorbic acid 2-glucoside content to a level of over 86% by weight, precipitating anhydrous crystalline ascorbic acid 2-glucoside by a controlled cooling method or pseudo-controlled cooling method, collecting the precipitated anhydrous crystalline ascorbic acid 2-glucoside, and ageing and drying the collected anhydrous crystalline ascorbic acid 2-glucoside.
