PURPOSE:To provide a sweet composition containing sophorose (2-0-beta-D- glucopyranosyl-D-glucose), having slightly lower sweetness than sucrose, giving a high-quality sweet taste and useful for dietary food because of its non- absorbable property. CONSTITUTION:A cyclic (1 2)-beta-D-glucan is treated with beta-D-1,2-glucanase originated from a sophorose-producing microorganism (e.g. Aspergillus fumigatus) at 35 deg.C for 16hr and the reaction liquid is passed through an activated carbon column. The adsorbed fraction is eluted with an aqueous solution of 10% ethanol and the eluate is subjected to fractional collection to obtain sophorose. The sophorose powder is sprayed with a small amount of water and lightly compression molded to obtain the objective sweet composition having the shape of cube sugar. |
