Phycocyanin is a dark blue powder isolated from spirulina. Mainly exists incyanobacteria, red algae and cryptophytes.
Phycocyanin is also generally divided into C-phycocyanin and R-phycocyanin. The former is mainly found in cyanobacteria, the latter is mainly found in red algae, and cryptophycos have both.
Its function is to absorb light (orange-yellow) energy and transmit light energy. It is not only a kind of protein, but also an excellent natural food coloring, and it is also a good health food.
The application research of phycocyanin is very extensive, which can be summarized as follows:
(1) Natural food coloring:Phycocyanin is a water-soluble coloring, non-toxic, pure blue, clear 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.
