Linablue® does not clump nor form solids in water to give the perfect natural blue color solution. spirulina extract stable 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. When used together with milk, egg or other ingredients containing protein, its color stability improves. Heat Stability As a colorant made of protein, it is recommended to add Linablue® in a solution after it has cooled down or at about 60°C while cooling immediately after adding.
