Abstract:

A natural yellow pigment was extracted from sunflower ligulate flowers, and its stability at different environmental conditions was studied. The results indicated that this pigment has good water-solubility, heat resistance, lightfastness, oxidation resistivity, and with the maximal absorption wavelength of 390 nm. Food additives and Cu2+, Na+, Ca2+, Zn2+, etc. metal ions are all benefit to the color maintenance of this pigment. In a word, this yellow pigment is cheap, simple and nature, and is able to be used as food additive and colorant.

Key words: sunflower ligulate flower, natural pigment, stability
