Natural Spirulina Extract Phycocyanin Powder

1. Solubility

Phycocyanin Powder dissolves rapidly in cold or warm water to form a uniform and transparent solution.

2. PH stability

Its tone remains stable within the PH range of 4.5 to 8.0. Due to the structure of Phycocyanin binding to proteins, aggregation and precipitation occur at a pH value of around 4.2. When used together with milk, eggs or other protein-containing ingredients, its stability will be enhanced.

3. Thermal stability

It is recommended to add Phycocyanin to the solution after it has cooled down. It can also be added to solutions at 60°C or lower, but Phycocyanin should be further cooled immediately after addition. Its stability will increase in high-density sucrose solution.

4. Light stability

When exposed to light, its stability will slightly deteriorate, but when used together with antioxidants such as sodium ascorbate, its color stability will be improved.

5. Alcohol solubility

If used in 100% alcohol, precipitation will occur, but Phycocyanin can dissolve in solutions with an alcohol content of less than 20%.

6. Stability in the presence of metal ions

Although affected by trivalent metal ions such as Fe3+ and Al3+, the impact can be mitigated by using chelating agents.

Functions and Applications

1.Food industry

As a natural blue pigment, Phycocyanin is used in food processing such as confectionery, beverages, and dairy products, replacing synthetic pigments (such as bright blue). Its heat resistance can reach 60-70℃, and the applicable pH range is 4-8. However, high-temperature or strong acid environments may cause fading.

2. Health product

Studies have shown that Phycocyanin can eliminate free radicals, inhibit inflammatory factors (such as TNF-α and IL-6), and enhance immunity by regulating the NF-κB pathway. Animal experiments have shown that it has anti-tumor potential and may exert its effect by inducing apoptosis of cancer cells or inhibiting angiogenesis.

3. Cosmetics

Some skin care products add Phycocyanin as an antioxidant ingredient to help reduce skin damage caused by ultraviolet rays, but the actual effect needs further clinical verification.

Advantage of Daynatural’s Phycocyanin

1. Phycocyanin is safe to use as it contains no organic solvents. Another attractive feature is that only a small amount of addition (about 0.01-0.1%) is needed to achieve a bright blue color.
2. It is the only blue colorant that meets the food standards of the United States and Europe and is derived from natural ingredients. It is recognized as safe and has a good record of use in a variety of foods such as ice cream, chewing gum and candies.
3. When dissolved in water, it presents a bright sky blue color.
4. The wavelength (max) with the maximum absorbance is 618 nm, which lies between the synthetic colorants Bright Blue FCF (FD&C Blue No. 1) and indigo carmine (FD&C Blue No. 2).
