Problem The present invention is to provide a generation method that can generate 3, 5-dihydroxy-4-methoxybenzyl alcohol, which was not found at all from raw oyster meat originally, at an extraction phase of oyster meat essence. Solution The present invention heats raw oyster meat from which 3, 5-dihydroxy-4-methoxybenzyl alcohol is not detected in a raw state at 98°C to 100°C for six hours or more to generate 3, 5-dihydroxy-4-methoxybenzyl alcohol from oyster meat liquid on which the heating process has been performed.
