The invention relates to an apple flavor enhancement agent and an apple flavor enhancement method. A conventional apple flavor fragrance can fully reproduce top-level apple aroma to middle-level fruit aroma and fruit feeling, but pulp feeling of the apple and juicy pulp feeling that spreads in the mouth when gnawing the whole apple are lacked. A small amount of sinensal and/or nootkatone is added into apple flavor food and drink or apple flavor perfume, so that sweet pulp feeling as well as hard and crunchy pulp feeling when gnawing the apple which can not be reproduced in the prior art are accompanied, furthermore apple-like aroma and flavor can be reproduced and enhanced.
