Abstract :1.サツマイモβ-アミラーゼによる沖縄産サトイモ澱紛アミロペクチンのβ-限界デキストリンは, 61%であった。2.過ヨウ素酸化法で求めた同アミロペクチンの平均鎖長は, 13であった。3.平均鎖長とβ-アミラーゼ分解限度との組合せによって求めた外側の鎖長及び内側の鎖長は, それぞれ, 10及び2であった。
1. The β-limit dextrine of the starch amylopectin of the wet-taro cultivated in Okinawa was determined as 61% by the β-amylase prepared from sweet potato. 2. The average chain length of amylopectin was found to be approximately 13 by periodate oxidation procedure. 3. The external and internal chain lengths were calculated as 10 and 2,respectively, by utilizing both of the average chain length and the β-limit dextrin.
