Phycocyanin is a pigment from the light-harvesting phycobiliprotein family, along with allophycocyanin and phycoerythrin.Its not only a natural colourful edible pigment but also a nutritious protein and health food. It's the only natural blue pigment that FDA recognised in the United States.
The European Union has already listed it as a raw material for food colourant and its use is unrestricted .The Chinese Food Additive Catalog also allow it to be used as a natural coloring agent.
Function and application
1.Phycocyanin is a water-soluble pigment, non-toxic, pure blue, can be used as a food colorant and cosmetic additive. Itself is a nutritious protein with a full range of amino acids.The body's essential amino acids account for 37.2% of the total weight.
Products that can be applied in：Ice cream, chewing gum, powder drink, cool drink, cake, candy, jelly, noodles, mustard, sugar coated tablets, capsules, etc.
2.Phycocyanin is a class of collagen with antioxidation, moisturizing, anti - allergy, antiphlogistic, freckle and other effects, its color shows beautiful ocean blue.
3.The experiment of phycocyanin in vitro shows that it has the effect of stimulating the production of erythrocyte colony(Similar to the effect of EPO). Phycocyanin can regulate a variety of important enzymes in the human body, play an important role in inhibiting the growth of cancer cells and promoting the regeneration of human cells . It can also regulate the immune system of the human body to improve the immunity. A lot of phycocyanin compound drugs have been developed to promote immunity against diseases. So in the future, Phycocyanin will be a safe & valuable target therapy drug and a tumor photosensitizer.
4.The blue colour of phycocyanin has fluorescence property. A characteristic reagent that can be used as a biological, chemical, and cytological experiment, the effect of fluorescence is 30 times as high as that of the common fluoro .
Phycocyanin is the main photosensitive protein in the phycogallin series , Its the light harvesting antenna for algae cells . The application of fertilizer to the leaf surface can promote plant photosynthesis.Photosensitization of phycocyanin caused by sunlight,The effect of an antiviral and anti bacterial effect on plants .Experiments by the Beijing Academy of Agricultural Sciences and the Shandong Vegetable Research Institute have proved that phycocyanin contains specific plant auxin.
