Product Description
Ingredients: Phycocyanin Powder
Spirulina is a type of Algae and Algae is the word used to describe a simple family of organisms that are neither plants, animals or microbes. They have no roots or leaves like plants do and instead either float around free (in the sea) or attach themselves to rocks or other substrates and in doing so help to oxygenate the our waterways.
In its complete form Spirulina is quite green due to its high Chlorophyl content. However, concentration of its minor pigment Phycocyanin, is what is used to produce this powder which gives a dark blue that is completely soluble in water.
Use amount: Typically up to 1% in a product with up to 0.3% being most typical to create a deep blue colour through your water-containing formulations.
pH tolerance: The blue colour of Spirulina starts to weaken as the pH increases towards pH 12 before almost completely dissapearing. It changes to a more greeny blue in more acidic formulations (pH 2-4). The deep blue colour dominates from pH 4-11 with the highest stability achieved at pH 5-6.
UV tolerance: Although not as unstable to UV as chlorophyll this colour will fade over time when exposed to UV either from daylight or shop lights.
Heat Tolerance: The pigment that produces this blue colour is protein based and has been found to be stable in hot springs where the temperature can reach 70C. That said, prolongued heating will start to degrade the protein structure and this can increase the aroma the colour emits and will eventually reduce colour intensity. For these reasons we recommend adding the colour in cool-down phase in most instances as stability studies have found this pigment performs best when conditions are kept below 45C.
Improving colour stability: This study found that stabilising the protein structure improves colour stability. This was best achieved by adding sodium chloride (salt) to your water phase at a level of between 2.5-20%.
