Phycocyanin E10 is a dark blue pigment extracted from spirulina. It is one of the rare pigment proteins in nature. It is not only bright in color, but also a nutritious protein with complete amino acid composition and high essential amino acid content. . It is not only a kind of protein, but also an excellent natural food coloring. At the same time, it has anti-oxidation, anti-tumor, anti-radiation, immunity enhancement, blood enrichment and other health benefits. Therefore, it is actively called "Diamond Food" by food experts. It is widely used in food coloring, health care products, medicines and cosmetics. It is a colored food permitted by the European Union and the only edible natural blue pigment approved by the FDA. Phycocyanin E10 is a blue powder with about 45% trehalose as a carrier and about 5% sodium citrate. Compared with conventional E18, although the protein content is lower than E18, the color difference between the two is at the same concentration. The concentration is not large, so E10 is more suitable as a natural pigment and more cost-effective.
This product is a protein-binding pigment, a porphyrin pigment protein unique to cyanobacteria, and has the same properties as proteins. It is the "light-harvesting antenna" in the seaweed cells, which transmits the absorbed light energy to the chloroplast for photosynthesis. The product is blue particles or powder. Soluble in water, insoluble in alcohol and grease. Organic solvents such as ethanol can cause irreversible denaturation of phycocyanin. The color of its aqueous solution is bright blue. Each phycocyanin monomer is composed of a subunit and b subunit. Its monomer (ab) has a molecular weight of about 40,000 d. When the pH is 6.5-8.0, it is trisomy (ab), and when the pH is 4.5-6.0, it is It exists in the form of six bodies (ab) with a molecular weight of about 230,000 d. No matter it exists in the form of monomer, trisomer or hexamer, it all presents a beautiful sapphire color under visible light. The color is bright, and it is determined to be quite stable under a variety of physical and chemical factors.Email:firstname.lastname@example.org
