When sucrose (+66.5°) is hydrolyzed with dilute acid or enzymes, it becomes a mixture of D -glucose (+52.6°) and D -fructose (-92.8°). During this process, the optical rotation changes from dextrorotatory to levorotatory (-20°), a change called inversion, and the resulting sugar mixture is called invert sugar. It gives a different taste to sucrose, is difficult to crystallize, but is easily absorbed, so it is used in food manufacturing as a nutritious substance, seasoning, etc. Honey contains 60-90% invert sugar.

スクロース(+66.5°)を希酸や酵素で加水分解すると,D-グルコース(+52.6°)とD-フルクトース(-92.8°)の混合物になる.その際,旋光度が右旋性から左旋性(-20°)に転じるので,この変化を転化(inversion),生成した糖混合物を転化糖という.スクロースと異なる味を与え,結晶化しにくいが吸収されやすいので,滋養剤,調味料など食品製造に使用される.ハチミツは60~90% の転化糖を含む. 出典 森北出版「化学辞典(第2版)」化学辞典 第2版について 情報 |
