https://www.taimaorganicbio.com/ Phycocyanin E25 (CAS 11016-15-2) is a premium natural blue phycobiliprotein extracted from food-grade Arthrospira platensis (Spirulina), widely used as a natural colorant and functional ingredient in food, beverage, dietary supplement, and cosmetic formulations. As a premium Phycocyanin E25 ingredient, it delivers scientifically documented antioxidant, anti-inflammatory, and neuroprotective benefits alongside its vibrant sky-blue coloration for diverse health and beauty applications. Produced using advanced aqueous extraction and purification technology from carefully selected premium Spirulina, each production batch undergoes strict quality control through UV-Vis spectroscopy and HPLC analysis, ensuring a consistent color value of E1% ≥ 250 (at 618nm) and purity ratio (A620/A280) ≥ 2.0 that meets international standards for food, cosmetics, and pharmaceutical ingredients. Naturally rich in complete amino acids, high-quality protein (≥55%), and potent antioxidants, Phycocyanin E25 serves as a key raw material in natural food coloring, functional beverages, dietary supplements, anti-aging cosmetics, and pharmaceutical research. Functions & Benefits Vibrant Natural Blue Color — Phycocyanin E25 delivers a brilliant, consistent sky-blue hue, serving as a clean-label alternative to synthetic dyes like FD&C Blue No. 1 in food and beverage applications. Its exceptional purity ratio (A620/A280 > 2.0) ensures minimal off-tastes and excellent clarity in liquid formulations, making it the preferred choice for manufacturers seeking natural coloring solutions. Potent Antioxidant Protection — Phycocyanin E25 exhibits powerful free radical scavenging activity, reducing oxidative stress at the cellular level and protecting tissues from environmental damage and premature aging. The protein-bound phycocyanobilin chromophores work synergistically to neutralize reactive oxygen species (ROS) and support the body’s natural defense system. Anti-Inflammatory Support — C-phycocyanin (C-PC), the primary bioactive component of Phycocyanin E25, inhibits pro-inflammatory mediators including COX-2 and suppresses the production of inflammatory cytokines. This provides significant anti-inflammatory effects that benefit joint health, cardiovascular wellness, and overall systemic balance. Neuroprotective Effects — Phycocyanin E25 scavenges hydrogen peroxide (ROS) in brain astrocytes, reduces astrogliosis and glial inflammation, and promotes nerve regeneration by increasing brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF). These properties make it valuable in formulations targeting cognitive health and neurodegenerative conditions. Hepatoprotective Properties — Phycocyanin E25 demonstrates significant liver-protective effects, supporting healthy liver function and aiding in detoxification processes. It helps protect hepatocytes from oxidative damage and supports the body’s natural cleansing mechanisms. Anti-Cancer Potential — C-phycocyanin (C-PC) has shown promising anti-cancer activity through multiple mechanisms: inhibition of tumor cell proliferation, induction of apoptosis, and modulation of critical signaling pathways. These properties are under active investigation for potential therapeutic applications in oncology research.
