難い。However, by employing such a distillation method, it is difficult to collect aroma components ranging from low boiling points to high boiling points that exist in natural products while maintaining an excellent and favorable aroma balance of the natural aroma components. This is practically impossible, and furthermore, changes in components due to heat during the distillation operation are unavoidable.

しまう欠点がある。On the other hand, when a solvent extraction method is adopted, the extraction process itself can be carried out at low temperatures, or the resulting extract can only be obtained in a highly diluted state with a solvent, resulting in weak aroma and unsatisfactory aroma. This is usually the result. When removing the solvent from such a solvent extract to obtain an aromatic juice concentrate, there are disadvantages such as changes in the components due to heat during the solvent removal operation and changes in the aroma balance due to loss of components due to volatilization. However, it has the disadvantage that it becomes an aroma component that is far from the original natural aroma component.

However, it is difficult to obtain natural aroma components that maintain their excellent and desirable aroma balance in a sufficiently satisfactory manner.

The above water-miscible organic solvent aqueous solution or aqueous solution is brought into contact with a chemically bonded silica sol to adsorb the natural aroma component onto the silica gel, and then the natural aroma component is eluted using ethanol. There is no unfavorable change in the fragrance, and there is no unpleasant change in the fragrance ingredients.

出させる効果を示すことを発見した。According to the research conducted by the present inventors, it has been found that silica gel adsorbents, which have traditionally been considered difficult to adsorb and recover aroma substances due to their strong activity, can be replaced with silica gel adsorbents. For example, alcohols,
The so-called "8 chemically bonded silica gel" (modified silica gel), which is made by chemically bonding amines, silanes, etc., prevents changes in aroma substances due to side reactions such as hydrolysis and dehydration of aroma substances found in one volume of ordinary silica sol adsorbent. A combination of the chemically bonded silica gel and ethanol as an elution solvent, It has been discovered that the natural aroma components, which have been adsorbed at a high concentration and with a good aroma balance, can be eluted again in a high yield while maintaining their excellent aroma balance.
