Description
Premium Phycocyanin E18 Natural Blue Pigment – High-Purity Water-Soluble Colorant for Food, Nutraceutical and Cosmetic Applications
Xi'an Le-Nutra Ingredients Inc specializes in manufacturing Phycocyanin E18, a standardized natural blue pigment-protein complex derived from clean-cultured Spirulina Platensis through aqueous extraction technology. Our product delivers a guaranteed color value of ≥180 CU at 620nm with phycocyanin content between 50-55%, supported by strict GMP and ISO quality systems. With 14+ years of plant extraction expertise, a 60,000㎡ production facility, and 3,000 tons annual capacity, we provide stable supply and consistent specifications for global food, supplement, and cosmetic manufacturers seeking clean-label blue colorant solutions.

What Makes Our Phycocyanin E18 Stand Out?
Our product offers exceptional water solubility in both cold and hot applications, creating brilliant sapphire blue solutions without precipitation. The fine powder format ensures easy integration into diverse formulations.
We maintain heavy metal levels well below international limits: Pb <0.5 ppm, As <1.0 ppm, Cd <1.0 ppm, and Hg <0.1 ppm. Microbiological safety meets food-grade standards with TPC ≤250 CFU/g and negative results for E.coli and Salmonella.
The purity ratio (A620/A280) typically exceeds 0.7, confirming food-grade quality. Our controlled extraction process preserves the natural antioxidant properties while delivering consistent color performance across production batches.

Key Performance Benefits
You gain access to a high-performance natural colorant that replaces synthetic blues like Brilliant Blue FCF. The bright blue colour is persistent in neutral pH compositions.
And not just colouring, but powerful antioxidant activity that helps neutralise free radicals. This dual functionality brings health-supporting claims to your finished items.
For eye-care formulations, our ingredient helps relieve visual tiredness and dry eye symptoms caused by long-term screen exposure. It helps liver cells to defend themselves by cutting down oxidative stress and metabolic load.
The immuno-modulating qualities elevate the natural defence potential by regulated activation of immune cells. These functional benefits place your products into the higher-end health orientated market segments.
Diverse Application Scenarios
Your beverage compositions provide brilliant natural blue hues in sports drinks, therapeutic waters and botanical beverages. Clean-label colourings without synthetic additives are good for dairy products such as yoghurt and ice cream.
You can also make immunity-support supplements and vision-care recipes for nutraceutical tablets and capsules. Besides colouring, great protein content offers nutritional value.
Phycocyanin E18 is used by confectionery producers in naturally coloured sweets and gummies which appeal to health-conscious consumers. It is included in cosmetic compositions in aqueous phase to achieve calming skincare products with antioxidant qualities.
The substance is very compatible with the Vitamin C, fruit extracts and water phase raw materials and guarantees the stability of the formulation with no precipitation.

Quality Assurance and Compliance
We conduct quality control in five dimensions, including UV-Vis spectrophotometric verification of the colour value, to ensure that the potency of E18 is within ±5% tolerance. Monitoring of purity ratio prevents too much spirulina proteins affecting odour or solubility.
All food practices are validated for safety by extensive microbiological testing. ICP-MS heavy metal analysis shows values much below FDA & EU regulatory limits.
Ash and moisture content ensure long shelf life and clumping during industrial mixing. With each production batch we provide full traceability report with COA, TDS and MSDS available on request.
We are FDA registered, ISO compliant, Kosher approved and meet the appropriate organic standards. We can help you meet your requirements in any global market.
