Product Description

Phycocyanin is a natural active substance extracted from Spirulina platensis. It appears as a dark blue powder with no visible impurities and exhibits excellent solubility, with a solubility of over 98% in water at 20℃. Its core component is phycocyanin (content ≥ 95%), along with a small amount of algal polysaccharides (≤ 3%) and 18 amino acids, including all 8 essential amino acids, resulting in a rich nutritional composition.

The product is categorized into food grade and cosmetic grade. The food grade complies with GB 1886.311-2022 National Food Safety Standard - Food Additive Phycocyanin, while the cosmetic grade adheres to QB/T 5641-2021 Cosmetic Raw Material - Phycocyanin. Both grades follow strict industry standards to ensure product compliance and safety.

Technical Analysis

1. Extraction and Purification Technology

It adopts supercritical CO₂ extraction combined with low-temperature centrifugal purification technology. Throughout the process, there are no chemical solvent residues, which maximizes the retention of the natural activity and purity of phycocyanin. Low-temperature centrifugal purification can effectively separate miscellaneous proteins and free pigments, laying a foundation for high-purity products in subsequent steps.

2. Purity and Stability Testing Technology

Purity Testing: Detected by High-Performance Liquid Chromatography (HPLC), the purity is measured by the A620/A280 ratio. The ratio of this product is ≥ 4.0, which is much higher than the industry average of 3.0-3.5. Technical testing methods ensure controllable purity.

Stability Verification: Through constant-temperature storage experiments (storage in the dark at below 40℃ for 6 months) and pH adaptability tests (within the pH range of 5.0-8.0), combined with absorbance monitoring technology, it is verified that the product's activity retention rate is ≥ 92% and the absorbance change rate is ≤ 5%. Technical data supports the stability performance.

3. Production and Quality Control Technology

The production process complies with the ISO 22000 Food Safety Management System, and low-temperature processing at ≤ 45℃ is adopted throughout the process to reduce the damage of high temperature to active ingredients, ensuring that more than 90% of active ingredients are retained. At the raw material end, it has obtained GAP (Good Agricultural Practice) certification, and combined with third-party SGS testing (covering 38 indicators), full-process technical quality control is realized from the source to the finished product.

Product Advantages

1. High Purity and Strong Stability

The purity (A620/A280) is ≥ 4.0, with no interference from miscellaneous proteins or free pigments; the activity retention rate is ≥ 92% when stored in the dark at below 40℃ for 6 months, and the color is stable within the pH range of 5.0-8.0. Compared with similar products in the industry, it has significant advantages in purity and stability, and can meet the long-term use needs of multiple scenarios.

2. Dual Effects of Natural Nutrition and Function

Nutritional Aspect: It contains 18 amino acids (4.2g/100g lysine, 1.8g/100g methionine) and trace elements such as zinc (3.2mg/100g) and selenium (18μg/100g). It complies with standards such as GB 28050-2011 and GB 14880, and can be used as a high-quality nutritional fortifier.

Functional Aspect: At a concentration of 100μg/mL, the scavenging rates for DPPH free radicals and hydroxyl free radicals reach 89.6% and 78.3% respectively. At a concentration of 0.1-0.5mg/mL, it can increase the survival rate of liver cells damaged by H₂O₂ by 35%-52%. It has prominent antioxidant and physiological activities, and has no potential risks of artificial ingredients.

3. Safety Compliance and Quality Assurance

The content of heavy metals (lead, mercury, arsenic) in raw materials is ≤ 0.1mg/kg, and the microbial indicators (total bacterial count ≤ 100CFU/g, Escherichia coli not detected) are far better than industry standards. It has obtained GRAS certification from the US FDA and approval from the EU EFSA (No.: E181). At the same time, it meets the requirements of vegetarian and halal diets, with a wide range of applicable people and reliable safety attributes.

Product Application

1. Food Field

Applicable Categories: Covers fruit and vegetable juice drinks, dairy products, baked goods (cakes, cookies, bread), health foods, etc., and can realize both coloring and nutritional fortification functions.
Usage Parameters: The addition amount for beverages is 0.05%-0.2% (presenting a uniform sky-blue color without precipitation), and the addition amount for baked goods is 0.1%-0.3% (the color retention rate is ≥ 85% after high-temperature baking). It is recommended to add at the low-temperature stage of ≤ 60℃ and avoid direct strong light to ensure stability.

2. Cosmetic Field

Applicable Categories: Includes skin care products (facial masks, serums, lotions) and color cosmetics (lipsticks, liquid blushes), which can replace artificial pigments and exert skin care effects.
Usage Parameters: The addition amount is 0.5%-2.0% for skin care products and 0.8%-2.0% for color cosmetics. The final pH of the product needs to be controlled at 5.5-7.5 to ensure stability. Its core functions are antioxidant, soothing and repairing, and it also provides a natural blue tone, which conforms to the "natural beauty" consumption trend.
