Phycocyanin is a dark blue powder isolated from Spirulina. It mainly exists in cyanobacteria, red algae and cryptoalgae. Phycocyanin is usually also divided into C-phycocyanin and r-phycocyanin. The former mainly exists in cyanobacteria, the latter mainly exists in red algae and cryptoalgae. Its function is to absorb light (Orange) energy and transmit light energy. It is not only a protein, but also an excellent natural edible pigment, but also a good health food.
Brief Introduction
Phycocyanin is one of the rare pigment proteins in nature. It is not only bright in color, but also a nutrient rich protein with complete amino acid composition and high content of essential amino acids.
Phycocyanin has the effects of anti-cancer, promoting blood cell regeneration, maintaining ovary and promoting the synthesis of elastin in human body. At the beginning of the 21st century, phycocyanin was widely used as advanced natural pigment in food and cosmetics and made into biochemical drugs in Europe, America, Japan and other countries. In 1986, phycocyanin, produced by the Japanese Institute of AIDS research and CONFIDENCE algae Nutritional Foods Inc, was used as a rehabilitative drug and nutritious food for cancer patients and leukemia patients, and achieved outstanding results in the treatment of confident.
Application
Phycocyanin has a wide range of applications, which can be summarized as follows:
(1) Natural food pigment: phycocyanin is a water-soluble pigment, non-toxic, pure blue, clear and lovely. It can be used as an additive for food colorants and cosmetics.
(2) Medical and health food: phycocyanin in vitro experiment can stimulate the formation of erythrocyte colony, similar to erythropoietin (EPO). Many kinds of phycocyanin compound drugs have been successfully developed abroad, and the Japanese Institute of Kangzi AIDS has successfully reported the improvement of anaemia and hemoglobin by phycocyanin. In 1982, Iijima et al. Studied that oral phycocyanin could improve the survival rate of mice injected with liver tumor cells, and the lymphocyte activity of mice in the experimental group was significantly higher than that in the control. They believed that the protein had the functions of promoting immunity and anti disease. In 1986, Schwartz and Shklar of Harvard hospital found that Spirulina phycocyanin inhibited some cancer cells.
(3) Special reagent for biological, chemical and cytological experiments: phycocyanin is blue and fluorescent. It can be used as some photodynamic research reagents for biology and cytology.
Effect
1. Anti cancer cells, anti-tumor.
Phycocyanin has been shown to inhibit the expansion of cancer cells. Scientists have found that phycocyanin can significantly inhibit the function of cancer cells. It can be made into anti-tumor adjuvant therapy drugs, and the adjuvant therapy for chemotherapy can enhance the immunity of the body. In a scientific experiment, rats with liver cancer were fed with extracted phycocyanin. It was found that the survival rate of rats fed with phycocyanin was much higher than that of the control group. After 5 weeks, 90% of the rats in the treatment group survived, while only 25% of the rats in the untreated group survived. After 8 weeks, 25% of the rats in the treatment group survived and all the rats in the untreated group died. This shows that oral phycocyanin can improve the survival rate of organisms with cancer
2. Antioxidant and free radical scavenging.
Phycocyanin can promote cell activity, remove free radicals in the body, improve ovarian function and promote the rapid synthesis of elastin. According to scientific research, phycocyanin can stimulate the formation of erythrocyte colony, similar to erythropoietin (EPO); It can adjust white blood cells and improve lymphocyte activity; Increasing physical fitness and promoting the growth of red blood cells can enhance the immune function and promote growth and development.
3. Anti allergy
The research team of Taiwan University published new research results on January 7 and found that the purified phycocyanin had an inhibitory effect on all allergies.
Another function of phycocyanin is fluorescent agent.
