Title: Study on the extraction and application of rose rugosa pigment
Abstract: As the research object with rose rugosa pigment,use the single factor experiment to the best extraction conditions rose pigment probes.The results indicated that the optimum extracting conditions were as followed: 0.1 mol/L hydrochloric acid-95% ethanol solution at 60 ℃ for 60 min with the solid-liquid ratio 1∶25.The pigment had the strongest absorption peak at 520 nm.Results also showed that rose pigment kept its stability under the acid conditions of metal ions,H2O2,Vc and food additives,but it was unstable in the effects of Fe2+and Fe3+,and it wasn't suitable for high temperature.
