[Features] The aqueous solution of cyanobacteria is a bright azure blue color, showing a beautiful sapphire color under visible light. Unstable under light, heat, and acidic conditions. It is stable under weak acid and neutral conditions, acidic conditions are prone to precipitation, strong alkali can be decolorized, stability to metal ions is poor, and dyeability is slightly poor.

[Use] Coloring agent, can be used in fruit and vegetable juice drinks, ice cream, popsicles, jelly, candy, cheese products, etc.

If used in conjunction with milk or protein materials, the stability of the product can improve.

2.Heat Stability

Because it is pigment combined with protein, it is suggested to be cooled rapidly before heat or around 60 ℃ , however, in a high concentrated sugar solution thermal stability of the product is improved significantly.

3.Light Stability

Light stability of the product performs a little bad , if used with sodium ascorbate as antioxidant, its light stability can significantly improve .

4.Ethanol Stability

Can be soluble in 20% alcohol solution, but can’t be soluble in 100% alcohol

5.Metal Ion Stability

The stability of the product is easily influenced by  3 valence metal ions, Fe, Al . metal block material can reduce its influence
