The pigment of Berberis heteropoda Schrenk is a type of anchocyanin and it is strong in resistance against light and to some extent, good in enduring heat and low consistence oxide. But it is poor in resistance against reductant and preservative. It can be applied to the condition of PH. It is also found that sucrose and most of metal ions do not exert negative effects on the stability of the pigment, except Fe3+, Fe2+and low consistence Pb2+, which have some extent effects. Adding stability matter can improve its stability. The harm trace elements contains are within requirement of the National Standard on food safety, As the lexicological study indicates that the pigment does not have any toxicity and mutagenesis, it can be used as edible pigment.
