Study on Stablity and Clearing Nitrite Function of Rose Flowers Pigment

Abstract

Abstract: The stability and nitrite clearing function of rose flowers pigment were studied.The results showed that maximunabsorption was observed at wavelength 304nm. Its stability was poor to light, while heat and reduction, while its stability wasgood to acid, alkali, oxidation and food additives. The common metal ions(except Fe3+, Cu2+)showed little obvious effects on thepigment. Moreover, it had better capability of clearing nitrite. The capability of clearing nitrite of the pigment was different withdifferent concentrations and acting time.

Key words: rose flowers pigment, stability, nitrite, clearing
