Separation and Method of Natural Pigments by Chromaticity Transformation of Green Seaweed

Green algae are distributed in various parts of the world and live on rocks and stones in coastal waters. And it is a green alga that can be seen in the four seasons in the area where the sea meets the river. Korea has four distinct geographical seasons and uses the sea, land, and experimental bottles to observe and investigate the structural colors and characteristics of green algae and the transformation of chromaticity in the seasonal environment of nature. Green algae have nine pigments genetically and seasonally change color due to UV light and temperature.Green algae (Chlorophyll-a and b) have pigments (green, blue, yellow, white, scarlet, red, red, brown, and black). According to genetic information in mitochondria, cell pigments are signal-transmitted, directing and determining cell pigments, and the colors of cells are physiologically subject to regular or irregular color synthesis due to UV effects.We found that various colors of green algae were followed by a chromatic transformation in some environments and conducted various observations and experiments.The colorimetric transformation of green algae in the ocean occurs frequently in summer seasonally and irregularly when exposed to ultraviolet light at high and low sea levels.On the ground, seasonal changes in the chromaticity of green algae appeared regularly, and they sometimes appeared irregularly.Changing from green to white is a strong ultraviolet or temperature effect.Green algae turning yellow is the influence of ultraviolet light at the top of the sea water.Green algae turning scarlet is white to pink and appears in seawater.The change of green algae to red appears as a transformation of scarlet to chromaticity.The transformation of green algae into red purple appears in the transformation and process of red chromaticity.The transformation of green algae into reddish brown occurs during the transformation of red purple to chromaticity.The change of green algae to brown appears as a transformation of chromaticity from reddish brown.The turning of green algae into black appears to be black due to the occurrence of acid volatile sulfide in contaminated seawater.The blue color of green algae appears bright blue as moisture evaporates, and in green and blue, they appear blue.The appearance of green algae in purple is attributed to the effects of red purple and brown.In other words, the structural colors of green algae can be transformed from light to dark in color and produce a variety of more pigments.The main production and study of natural blue pigments over a long period of time is cyanobacterium arthrospira (Spirulina) platensis, which is responsible for the production of one of the blue compounds of eukaryotic algae as metal oxides, animals, plants and marine microorganisms.Recently, there are indigo dine pigments by extracting pigments of yttrium, indium, manganese metal compounds, and bacteria used as cosmetics, which are produced for industrial use as blue pigments.Despite this development, there has been no study of blue pigments in marine green algae, and interest in these products is very high because there is no stable natural blue pigments in nature.We are the first in the world to identify the structural colors and chromatic transformations of green algae as marine life.We developed technology and research on natural pigments in the future, enabling the foundation for mass production. This study focused on the characteristics of green algae and the production of blue pigments, which can be an important source of blue pigments, along with potential applications in the cosmetics and food industries and other industries.
