Abstract: The stability of pigment extracted from mangosteen was studied in this paper. The results showed that the pigment is soluble in alcohol and highly sunlight-resistant and heat-resistant. The pH value affects the stability of the pigment but it is stable in range of pH3~7. It lumps well as food additive in common use of glucose, sucrose, sodium benzoate, but NaCl and oxidizer and reducer can harm its stability. K+, Na+, Ca2+, Mg2+, Zn2+ hardly affect the color and stability of the pigment, but the color turns deep with Cu2+, while Fe3+ greatly damages the pigment.

Key words: mangosteen, pigment, stability
