ABSTRACT:
Spirulina blue, which is not soluble at low pH, is subjected to enzymatic hydrolysis in an aqueous alkaline medium. The pH of the aqueous system is lowered and the liquid phase is dried to produce a blue dye in dry form which is soluble at low pH. The blue dye is useful as a blue colorant in food products, particularly food products, such as beverages, in which acid solubility is desired.
