The science of colorants is found in numerous areas of our lives. Artificial colorization can complement the natural colors of products, such as food or daily commodities. However, synthetic colorants in the artifical colorization are more often than not unwelcome to customer's liking. In contrast, the natural colorants, which are the sources of beauties in flowers or fruits, have limited usefulness for industrial applications. In this dissertation, I investigated the science of natural colorants; their classification, molecular structures, chemical reactivities, etc.
Most natural colorants, investigated in this dissertation, are not stable unless they are isolated to their molecular forms and their colors diminish slowly. The isolated molecular colorants have several acid-base structures, which are usually distinguished by the bindings of protons and accordingly by pH of the solution. The color of the natural colorants therefore changes with pH of the solution, leaving a possibility that the natural colorants can be developed for pH indicator. In this disseration, I showed the structures of numerous natural colorants and their visible absorption spectra under numerous chemical environments such as pH. Studying related sciences of the natural colorants would hopefully stimulate our interests in chemicals found easily in our daily lives.
