Gardenia Blue is manufactured by enzymatic (beta-glucosidase) conversion of geniposide in gardenia fruit extract, followed by reaction with amino acids to form stable blue pigments (genipin-amino acid polymers).
It is one of the few natural sources of true blue colour for food applications, widely used in East Asian markets. Provides stable colour at pH 4-8 and is heat-resistant.
