Abstract: In the thesis, the extration and stability of pericarp pigment from Citrus reticulata Blanco‘ Jiao gan’ was studied for its further development and utilization. Results showed that the color of pericarp pigment from Citrus reticulata Blanco ‘Jiao gan’ was glassy yellow, and the optimum extraction technics was solvent 70% ethanol, temperature 50 ℃, the ratio of material to liquid 1:30 and extraction time 360 min. The pigment was stable to light, heat, acid and alkali (pH3~11), oxidant and reductant, food additive and metal ion, and the pigment had good stability, safe and accessibility as a kind of natural plant pigment.
