PROBLEM TO BE SOLVED: To provide an aroma adsorption desorption agent that can easily desorb the aroma component under a predetermined condition while maintaining the retention of the once adsorbed aroma component.SOLUTION: The aroma adsorption desorption agent that adsorbs aroma components contains, as a main component, a molecular-weight-lowered starch whose molecular weight has been lowered by a treatment to obtain a partially-decomposed-starch by enzymolyzing a natural starch to have the molecular weight dispersion degree (weight average molecular weight/number average molecular weight) in 100 to 1600 and to have the dextrose equivalent (DE) in 0.5 to 10.0, or by a treatment to obtain a finely-dispersed-starch finely dispersed by gelatinizing a natural starch and irradiating the same with ultrasonic wave.COPYRIGHT: (C)2015,JPO&INPIT【課題】いったん吸着した香気成分の保持を維持しつつ、所定の条件下において簡単に香気成分を放散することができる香気吸着放散剤を提供する。【解決手段】香気成分を吸着する香気吸着放散剤は、天然デンプンを酵素分解し分子量分散度(重量平均分子量/数平均分子量)を100~1600とし、かつ、デキストロース当量(DE)を0.5~10.0としたデンプン部分分解物を得る処理、または天然デンプンを糊化しこれに超音波を照射して微分散化した微分散デンプンを得る処理によって低分子量化した低分子量化デンプンを主成分として含有する。【選択図】なし
