[English name] Spirulina blue ; Algae blue ; Lina blue; Phycocyanin
[Legal number] CNS 08.137; Japan Natural No. 230; KFDANo. 37
[Source] The natural pigment extracted by modern biotechnology is used as a raw material for the spores of the cyanobacteria of the cyanobacteria. The ingredients are mainly phycocyanin and phycocyanin.
[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.
[Product special effects] It is not only bright in color, but also very rich in protein. Its amino acid composition is complete, and essential amino acids account for 37.2% of the total.
Powder can quickly dissolve in cold water or warm water, form a uniform transparent aqueous solution.
PH Stability Within PH5 ~ 8 this color of powder won’t change. Because this product is a kind of pigment combined with protein pigment, so around PH4.2 will flocculation and precipitation phenomenon occur. If used in conjunction with milk or protein materials, the stability of the product can improve.
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.
Light stability of the product performs a little bad , if used with sodium ascorbate as antioxidant, its light stability can significantly improve .
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
