Studies on quantitative changes of α-amylase and free sugar in fermentation of Awamori Moromi (Department of Agricultural Chemistry)

1.泡盛醪中のα-amylaseは発酵初期において麹米に吸着されているか, あるいは麹菌体に結合状態にあるが発酵が進むにしたがって醪滬液相に溶出する。2.糖化力は糖成分の変化と一致している。3.ペーパークロマトグラフィーにより泡盛醪中からglucose, maltose, xylose, galactose, arabinose, riboseの6種類の糖類を検出した。4.maltoseは発酵初期においてわずかに検出されたが30時間目頃にはほとんど消失した。1. As Awamori fermentation proceeds, α-amylase of the Koji was gradually eluted to the Moromi (mash) solution. Saccharifying activity of the Moromi was in agreement with the change in the composition of sugar. 2. Glucose, maltose, xylose, galactose, arabinose and ribose were chromatographically detected from the Awamori Moromi. 3. In the beginning of the fermentation, a small amount of maltose was detected in the Moromi solution. After the fermentation proceeded for 30 hrs., however, the maltose disappeared almost
