Example 1 Air was dramatically blown into a 0.05% L-Dopa aqueous solution (pH 7.0 phosphate buffer), and the blackening of the liquid was reduced to 470%.
It is measured by absorption at a wavelength of nm. This reaction indicates the production of bald melanin, and the reaction is completed in about 3 days at room temperature.

Now, when this reaction is carried out under ultraviolet irradiation, it is significantly accelerated. A UM-452 (Ushio Inc.) high-pressure mercury lamp (having a strong line spectrum between 665 and 579.1 nm) was used as the light source, and the distance between the light source and the specimen was 95111. When the above-mentioned reaction is carried out at a liquid temperature of 20 to 25°C, it is completed in 3 hours.

Example 4 Effect of γ-pyrone on the body color of tiger prawns When prawns are reared in shallow artificial seawater and irradiated with ultraviolet rays, their body color significantly turns black. This seems to be due to increased melanin formation. At this time, when 0.1% of a γ-pyrone derivative was added to the artificial seawater, blackening was significantly suppressed.
