  A physiologically active substance of aglycon type, in particular, aglycon isoflavone, can be efficiently produced, without resort to any acid/alkali treatment or fermentation and substantially without changing the physical properties of a material, by treating the material with a sufficient amount of diglycosidase for a sufficient period of time at an appropriate temperature and pH so that a physiologically active substance of glycoside type contained in the material can be converted into the physiologically active substance of aglycon type. Moreover, by using diglycosidase and/or a specific enzyme preparation, the aglycon content in a protein or protein-containing food can be increased and the flavor thereof can be improved.

  一种生理活性物质，特别是糖苷型异黄酮的活性物质，可以通过使用足够量的二糖苷酶在适当的温度和pH下足够长的时间处理原料，而无需采用任何酸碱处理或发酵，并且基本上不改变材料的物理性质，从而高效产生。这样，原料中含有的糖苷型生理活性物质可以转化为糖苷型生理活性物质。此外，通过使用二糖苷酶和/或特定酶制剂，可以增加蛋白质或含蛋白质食品中的糖苷型物质含量，并改善其风味。

  在适当的温度和 pH 值下，用足量的双糖苷酶对材料进行足够时间的处理，使材料中含有的苷类生理活性物质转化为苷类生理活性物质，就可以有效地生产苷元类生理活性物质，特别是苷元异黄酮，而无需进行任何酸碱处理或发酵，也基本上不会改变材料的物理性质。此外，通过使用二糖苷酶和/或特定酶制剂，可以增加蛋白质或含蛋白质食品中的苷元含量，并改善其风味。

  The present invention relates to the use of certain oleanene-type triterpene glycosides of formula (I) and/or physiologically acceptable salts thereof wherein M is hydrogen or hydroxyl, preferably hydroxyl, and A is a carbohydrate moiety, preferably an oligosaccharide moiety, for modifying (i.e. modulating) or masking (i.e. reducing or suppressing) unpleasant taste impressions, in particular bitter and/or astringent taste impressions and to a corresponding method for modulating or masking an unpleasant taste of a substance or substance mixture. The present invention also relates to compositions, in particular orally consumable compositions, comprising (a) one or more compounds of formula (I) or a physiologically acceptable salt thereof, and (b) one or more substances with unpleasant taste, in particular bitter and/or astringent taste.

  本发明涉及式 (I) 的某些齐墩果烯型三萜苷和/或其生理上可接受的盐的用途 其中 M 是氢或羟基，最好是羟基，以及 A 是碳水化合物分子，最好是寡糖分子、 用于改变（即调节）或掩盖（即减少或抑制）不愉快的味道印象，特别是苦味和/或涩味印象，以及用于调节或掩盖物质或物质混合物的不愉快味道的相应方法。 本发明还涉及组合物，特别是口服组合物，包括(a)一种或多种式(I)化合物或其生理上可接受的盐，和(b)一种或多种具有令人不快的味道，特别是苦味和/或涩味的物质。
