PURPOSE:To obtain extract having excellent solubility in water system and in mixed solution of water/ethanol by adding water to kiwi fruit after heat treatment, crushing, filtering, adding ethanol to resultant filtered solution, stirring, leaving at rest to age and filtering. CONSTITUTION:About two times amount of water is added to kiwi fruit after heat treatment and the fruit is crushed, filtered, and then ethanol is added to same amount of resultant crude solution. The solution is stirred, then aged by leaving at rest in cooling place for a whole day and night, preferably 2-3 days, thus filtered by filter paper, with concentrating as necessary, to afford extract solution of kiwi fruit containing >=1.0% water-soluble extract calculated as solid component. Stable solubility of said extract in water system is preserved and generation of turbidity or precipitation is extremely slight, and further, unpleasant odor is not emitted. |
