FUNCTION IN FOODS: A bright egg-yellow food colour
ALTERNATIVES: Other yellow food colours, although not of exactly the same hue, include: Mixed carotenes; Betacarotene;
Carminic acid; Sunset yellow; Quinoline yellow; Crocin
TECHNOLOGY OF USE IN FOODS: For oil-based applications, a solution of the oleoresin in vegetable oil can be directly applied.
For aqueous-based food products, water-dispersible forms are required. These are generally oil-inwater
emulsions with the pigment dissolved in the oil phase and using a food-grade emulsifier such as
polysorbate.
SYNERGISTS: Antioxidants/ Emulsifiers (e.g. polysorbates)/ Vegetable oil
ANTAGONISTS: Sulphur dioxide/ Oxygen/ Metal ions
FOOD SAFETY ISSUES: None known
