Phycocyanin: Blue Nutrition Code in Microalgae

Phycocyanin, a special pigment protein extracted from spirulina, breaks through the limitations of traditional ingredients with its dual properties of "natural blue" and high nutritional value, becoming a "new favorite" in the food, beauty, and health sectors.

Unlike the extraction of common plant-based ingredients, the cultivation of phycocyanin raw materials holds a "technological secret." The extraction process prioritizes "activity preservation," abandoning traditional organic solvent extraction in favor of a low-temperature water extraction process combined with ultrafiltration membrane separation technology. This removes impurities from the microalgae cell walls while preserving the phycocyanin's three-dimensional structure. Its nutritional density far exceeds that of most plant-based proteins.

The uniqueness of phycocyanin lies primarily in its ability to address the food industry's "blue" challenge. Natural Blue Pigments are scarce on the market, with most relying on artificial synthesis. Phycocyanin, however, is not only an FDA-certified "GRAS" ingredient but also boasts exceptional stability: its color remains stable within a pH range of 3-10, it can withstand prolonged heating below 80°C, and it remains colorfast or odorless even when added to acidic beverages or baked goods.

More importantly, the nutritional benefits of phycocyanin are more than just generalities. The phycocyanin it contains is a unique porphyrin that binds to human hemoglobin, aiding in iron absorption. Its antioxidant capacity is also clearly supported by data: DPPH free radical scavenging experiments have shown that phycocyanin's antioxidant activity is 2.3 times that of vitamin C, effectively reducing oxidative damage to skin cells. This is why it is so popular among beauty brands.

In addition to its common applications in food and cosmetics, phycocyanin is also used in pet food. Adding 0.5% phycocyanin to dog nutritional cream can boost a pet's immunity and reduce skin inflammation. In aquaculture, it serves as a natural colorant for fry, brightening the color of ornamental fish without the risk of residue. Even in the biomedical field, phycocyanin's fluorescence properties are used in cell imaging studies, making it an auxiliary tool in scientific research.

As a company deeply engaged in microalgae extraction, Risun maintains strict standards for phycocyanin quality control. Every batch of microalgae raw material undergoes heavy metal testing, the extraction process is sterile throughout, and the finished product is tested for purity and activity using high-performance liquid chromatography to ensure compliance with the requirements of GB 1886.246-2016 National Food Safety Standard - Food Additives - Phycocyanin. We also offer customized services to meet diverse customer needs: we provide liquid phycocyanin for beverage companies (convenient for direct addition) and powdered products for health supplement companies (easy to store). Our technical team provides application guidance and helps solve formulation problems.

From microscopic algae cells to phycocyanin, a component of everyday life, this small ingredient is unleashing powerful energy. Risun will continue to explore the potential of microalgae, leveraging phycocyanin in even more applications, and providing customers with a product experience that is both natural, healthy, and innovative
