Phycocyanin (PC) is a dark blue powder. It is both a protein and a good natural food coloring. It is mostly found in Spirulina, Anabaena and Auricularia, among which the protein content in Spirulina cells is rich.
Phycocyanin has anti-cancer, promote blood cell regeneration, nourish the ovaries, and promote the synthesis of elastin in the human body. At the beginning of the 21st century, in Europe, America, Japan and other countries, phycocyanin was widely used as a high-grade natural pigment for food and cosmetics, and it was made into biochemical drugs. In 1986, Confident Phycocyanin, developed by Japan's Kangpai AIDS Research Institute and produced by CONFIDENCE Algae Nutritional Food Company, was used as a rehabilitation medicine and nutritious food for cancer patients and leukemia patients, and achieved outstanding therapeutic effects.
The application research of phycocyanin is very extensive and can be summarized as follows:
(1) Natural food coloring: Phycocyanin is a water-soluble coloring, non-toxic, pure blue, bright and lovely, and can be used as food coloring agent and cosmetic additive.
(2) Medical and health food: Phycocyanin in vitro experiments can stimulate the formation of red blood cell colonies, similar to erythropoietin (EPO). A variety of phycocyanin compound drugs have been successfully developed abroad. The Kangpai AIDS Research Institute of Japan has successfully reported that phycocyanin can improve anemia and increase hemoglobin. In 1982, Iijima et al. studied that oral administration of phycocyanin in mice increased the survival rate of mice injected with liver tumor cells, and the activity of lymphocytes in the experimental group was significantly higher than that of the control. They believed that the protein had the function of promoting immunity and anti-disease. In 1986, Schwartz and Shklar of Harvard Hospital in the United States discovered that spirulina phycocyanin has an inhibitory effect on some cancer cells.
(3) Special reagents for biology, chemistry and cytology experiments: Phycocyanin is blue with fluorescence, and can be used as some photodynamic research reagents for biology and cytology.
