The results showed that the pigment had a high resistance to heat and it′s stability seemed to be affected greatly by pH, and red pulp plum was suitable to be applied for making acid food. Several kinds of metallic ions including Na + 、Zn 2+ had an effect of reinforcement on its tone, however Fe 3+ had a disruptive effect. Sucrose had no undesirable effect, but vitamin C had a significant undesirable effect. Also the preservative of sodium benzoate had a definite undesirable effect. The pigment showed strong resistance to reducer sodium sulfite but was very weak in resistance to oxidizer hydrogen peroxide.展开更多
