PROBLEM TO BE SOLVED: To provide a new starch decomposition product showing a low viscosity, low sweet taste, and a low osmotic pressure, compared to an existing starch decomposition product showing the same DE value.SOLUTION: This starch decomposition product is such that a content of components with a glucose polymerization degree (DP) of 8-19 is &ge32%, and a content of components with a glucose polymerization degree (DP) of &ge20 is &le30%. The starch decomposition product shows a low viscosity, low sweet taste, and a low osmotic pressure, compared to an existing starch decomposition product showing the same DE value. A method for producing the starch decomposition product, including at least a process of making debranching enzyme act on starch, and a process of making branching enzyme act on starch is also provided.COPYRIGHT: (C)2011,JPO&INPIT【課題】同一のDE値を示す既存の澱粉分解物に比べ、低粘度、低甘味、低浸透圧を示す新規な澱粉分解物を提供すること。【解決手段】グルコース重合度(DP)8~19の含量が32%以上、かつ、グルコース重合度(DP)20以上の含量が30%以下の澱粉分解物を提供する。該澱粉分解物は、同一のDE値を示す既存の澱粉分解物に比べ、低粘度、低甘味、低浸透圧を示す。また、澱粉分解物を製造する方法であって、澱粉に枝切り酵素を作用させる工程と、澱粉に枝作り酵素を作用させる工程と、を少なくとも含む澱粉分解物製造方法を提供する。【選択図】なし
