| Outline of Final Research Achievements |
It is known that chlorophyll of a green pigment is easily discolored under the light. In this study, we investigated the physico-chemical properties of chlorophyll species in water-alcohol solution and in aqueous solution containing surfactan. And we studied the effect of chlorophyll species on discoloration under UV light. As a result, chlorophyll was easily discolored in the monomer type, but it was revealed that the discoloration of chlorophyll was prevented by the formation of small aggregates of nano-size. In the future, it is thought that it is possible to prevent the discoloration of chlorophyll which was impossible so far by using this technology, and to maintain the green color of green tea and vegetable drink for a long time.
