The present invention provides a method for producing tagatose crystals from an aqueous system using no organic solvent. In this method, seed crystals of tagatose are added to a tagatose solution in which a tagatose purity of solid contents in the solution is at least 70% and a solid contents concentration in the solution is 60 to 98 mass %, and crystallization of tagatose is carried out by stirring and cooling the solution while keeping a degree of super saturation of tagatose at 1.25 or lower. It is preferred that the solution containing tagatose is a solution containing no organic solvent. It is further preferred that a part of massecuite for which the crystallization is completed is added to a mother liquor so as to produce the tagatose crystals semi-continuously or continuously. It is furthermore preferred that the tagatose crystals formed from the massecuite are separated by centrifugation or filtration and dried to obtain tagatose crystals.

Process for producing crystalline tagatose

CGTase enzymatically acts on starch, dextrin, amylopectin, and amylose to produce primarily &#x3b3;-CD, with quantities of &#x3b2;- and &#x3b1;-CD produced being smaller than the quantity of &#x3b3;-CD produced, has an optimum pH of 10.5-11.0, an optimum temperature of about 60&#xb0; C., a stable pH of 6-11, and temperature stability, exhibits residual activity of not less than 90 percent with a 15 minute-treatment at 50&#xb0; C., is produced by culturing a(for example, FERM B-7156), reacts with starch or the like to produce principally &#x3b3;-cyclodextrin.

Process for producing starch sugar composition

A .beta.-glucooligosaccharide-containing composition comprising at least one material selected from food, drink and medicine, and at least one selected from a glucooligosaccharide comprising at least one .beta.-1,6 bond and a reduced product thereof. A method of improving intestinal floras, comprising administering to a human or animal for ingestion a physiologically effective amount of at least one selected from a glucooligosaccharide comprising at least one .beta.-1,6 bond and a reduced product thereof. The ingestion of the .beta.-glucooligosaccharide and/or the reduced product thereof can bring about promotion of the selective growth of useful bacteria such as Bifidobacteria and lactic acid bacteria, inhibition of the growth of harmful bacteria or putrefactive bacteria, and hence improvement in the intestinal floras.
