BINMEI, global leader in blue spirulina

Blue spirulina(phycocyanin) is a natural blue food colorant of phycocyanin derived from Spirulina. Mixed with red, yellow, and other colorants, it is possible to obtain green, purple, and other neutral colors. It is fully in compliance with regulatory criteria for coloring food in the EU and the USA as well as in Japan, Korea, and other Asian countries. Like chlorophyll and carotenoid, phycocyanin takes part in photosynthesis. It is an antioxidant and has other important properties to support a healthy lifestyle. It is not only a high-quality plant protein but also a good raw material for nutrition and health care. The amino acid composition of phycocyanin is the closest to the essential amino acid composition of the human body. At the same time, it is also the natural material with the strongest antioxidant capacity and the widest antioxidant range among water-soluble raw materials. It can be widely used in food coloring, such as ice cream smoothie fudge beverage baking, etc., it is a pure natural blue, so eating does not have any side effects on the human body, so your tongue will not become blue color.

Properties

① Solubility
Spirulina blue powder can dissolve quickly in cold and warm water to make a homogeneously transparent solution.

② pH stability
Its color shade is stable at around pH 4,5 – 8,0.

Aggregation and precipitation occur at around pH 4,2 as phycocyanin has a combined structure with protein. Used together with milk, egg, or other ingredients containing protein, its color stability improves.

③ Heat stability
Being a colorant combined with protein, it is recommended to add Spirulina blue in solution after cooled down or at about 60°C and cool it down immediately after adding. Its stability improves in a high-density sucrose solution.

④ Light stability
Its color shade deteriorates when exposed to light, but when used together with antioxidation agents like sodium ascorbate, its color stability can improve.

⑤ Solubility in alcohol
Precipitation occurs if used in 100% alcohol, but it can dissolve in a solution with less than 20% alcohol.

Appearance

When dissolved in water, the color shade is the vivid sky blue.
The color shade of BINMEI Spirulina blue is much more brilliant and vivid than gardening blue.
