Phycocyanin Bulk Powder — Natural Blue Colorant for Food, Nutraceutical & Cosmetic Applications

Shaanxi New Things Biotech’s phycocyanin bulk powder, made from Arthrospira platensis (Spirulina), has a bright electric blue colour and specification from E6 to E40. This water-soluble biliprotein pigment is verified by UV and HPLC testing procedures and is ISO 9001, KOSHER and HALAL approved. It provides a clean-label alternative to synthetic colourants in the food, nutraceutical and cosmetic industries. We have stock ready and despatch within 2-3 working days after order confirmation with comprehensive third-party HPLC documentation.

Product Specifications

Product Characteristics & Technical Profile

Phycocyanin is a light harvesting biliprotein that contains a protein backbone covalently attached to open chain tetrapyrrole chromophores. The vivid blue colour stems from a maximum absorption at 618 nm, and it is one of the very few recognised natural blue colourants worldwide.

The powder dissolves in aqueous systems readily, without precipitation or sedimentation. This makes it very reliable in beverages, dairy formulas and confectionary where visual uniformity is important.

Your formulation is directly affected by grade selection. For example, E25 is roughly 38% more concentrated than E18, leading to lower inclusion rates and less impact on the flavour character of the finished product. The right grade helps you find a happy medium between colour depth and a neutral flavour.

The purity ratio (A618/A280 >2.5) confirms the high purification of the protein. This is an important quality marker for B2B buyers looking at batch to batch consistency of ingredients.

Application Scope

Food & Beverage: Ideal for heat-sensitive applications such as cold-pressed juices, handmade ice creams and confectionery. In dairy systems, addition of the pigment after pasteurisation retains the intense blue colour and resists syneresis very well.

Nutraceuticals & Supplements: Used in antioxidant superfood blends, recovery capsules and athletic nutrition products. It is not simply a colourant, it is a functional activity because Phycocyanin has the capacity of scavenging free radicals and supports the hematopoietic function.

Cosmetics & Personal Care: Used in high-end serums, face masks, and blue ocean aesthetic skincare. It is utilised as a natural colourant and as a bioactive agent with anti-inflammatory properties in controlled emulsion systems.

Quality Assurance and Safety

Every phycocyanin bulk batch is tested using a multi-stage quality control method. The first check is extinction coefficient at 618 nm to establish potency. Secondary testing: SDS-PAGE electrophoresis for protein integrity analysis to check for degraded fragments.

We screen for heavy metals using ICP-MS technology and use GC-MS testing to screen for any potential solvent residues. Because extraction is a pure aqueous process no chemical solvents are involved at any stage.

The stability testing under accelerated light and heat settings establishes the half-life of the pigment in different matrices. This allows you to predict actual world performance prior to full scale production.

We can provide HPLC third party test reports upon request to assist your regulatory filing and procurement compliance.

Storage and Handling Guidelines

Keep away from direct light and moisture in a cool place below 20°C. UV radiation causes degradation of the chromophores and decreases shelf life.

After opening, it is suggested to use sealed packing with nitrogen flushing or vacuum film. Shelf life is 24 months under suitable conditions.

Above 60°C phycocyanin starts to denaturate. For industrial processing, add the powder after any thermal treatment phase, or use a cold-fill technique to maintain colour integrity.

In case of acidic applications with a pH fall below 4.0, a stabilised or micro-encapsulated version is recommended to avoid protein precipitation.

Packing and Delivery

Standard packing 25kg/drum, vacuum composite sheet, aluminium foil nitrogen-filled bag, optional light-resistant bottle. OEM/ODM orders are welcome with customised labelling and multi-language packaging.

Deliveries can be made by courier, air freight and ocean freight. In stock and delivered in 2-3 working days following order confirmation to keep your production plan on track.

Shaanxi New Things Biotech has sophisticated GMP compliant production base in Xi'an, with supercritical fluid extraction equipment, molecular distillation technologies and automatic production lines.

Each batch is digitally traced from receipt of raw materials, through quality inspection, to delivery of the finished product. This guaranties full transparency in the supply chain.

Flexible production capacity from experimental batches in kilograms to large-scale commercial orders. We have our own R&D Centre and Quality Control Centre. Technical support on unique formulations is always accessible.

FAQ

Q1: Is the product powder stable during heat processing?

A: It begins to denature above 60°C. Cold-fill or post-heat addition is recommended to maintain full color intensity in commercial applications.

Q2: Will it dissolve completely in beverages without clumping?

A: Yes. The ultra-fine micronized powder disperses instantly in water with no residue or sedimentation in dairy or beverage systems.

Q3: Is it suitable for acidic beverages?

A: Below pH 4.0, protein precipitation may occur. A stabilized or encapsulated version is recommended for low-pH applications.

Q4: What is the difference between E18 and E25 grades?

A: E25 is approximately 38% more concentrated than E18, allowing lower usage rates and less impact on flavor.

Q5: Are any chemical solvents used during extraction?

A: No. Pure aqueous extraction and centrifugal separation are used throughout, delivering a 100% solvent-free product.

Q6: Can you support stable year-round supply?

A: Yes. Integrated cultivation operations and sound inventory management ensure consistent availability and stable pricing regardless of season.
