The first object of the present invention is to provide a method for preparing an aroma-retaining material, which enables to increase the adsorbed aroma amount, retain the aroma for a long period of time, and impart stability. The second object of the present invention is to provide an aroma-retaining material, which can retain aroma for a long period of time and has satisfactory stability. The third object of the present invention is to provide a composition comprising the aroma-retaining material. The forth object of the present invention is to provide an aroma-retaining agent, which enables to stabilize an aromatic substance. The fifth object of the present invention is to provide a retained-releasing bactericide comprising the aroma-retaining material. The present invention solves the above objects by providing a method for retaining an aroma in such a manner of mixing an aromatic substance and a cyclic tetrasaccharide or the mixture of cyclic tetrasaccharide and its saccharide derivative(s), an aroma-retaining material obtainable by the method, a composition comprising the aroma-retaining material, an aroma-retaining agent comprising a cyclic tetrasaccharide or a mixture of a cyclic tetrasaccharide and its saccharide derivative(s) as effective ingredients, and a bactericide using the aroma-retaining material having a sustained-release property. |
