Phycocyanin is a blue water-soluble pigment extracted from spirulina. It is also 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 essential amino acids. It accounts for 37.2% of the total. It can be used as a natural food coloring agent, a raw material for functional foods, an additive for cosmetics, and the like.
Natural pigment for food
As a pure natural pigment, phycocyanin has been widely used in high-grade natural pigments in foods and cosmetics in Europe, America and Japan in the early 21st century. Algin blue pigment is a natural blue pigment approved by the US FDA and is also listed as a color food raw material in the European Union.
The phycocyanin is a collagen-like protein with whitening, moisturizing, anti-allergic, and ecchymosis effects. For example, French Ou Lan Ya, a well-known female friend, and the domestic brand Danzi have used phycocyanin raw materials in their customized cosmetic products to give the skin a natural care while creating a marine-like color.
Medicine and health food field
Studies have confirmed that phycocyanin can scavenge free radicals, and as a natural antioxidant, it can help remove cell damage, aging, and inflammatory reactions caused by harmful free radicals.
In addition, due to the fluorescent properties of phycocyanin, its fluorescence is 30 times that of ordinary fluorescein. It can be used as a photosensitizer in some photodynamics such as biology and cytology. It can also be promoted as a light-sensitive protein. Plant photosynthesis, while being stimulated by light energy, produces a photosensitive reaction, thus making the product antiviral and antibacterial.
