摘要: 本实验对西番莲果皮色素Ⅰ的稳定性进行研究。结果表明:pH值对西番莲果皮色素Ⅰ的影响明显,在pH1~4之间该色素较稳定;金属离子Cu2+、Al3+对色素有增色作用,而Fe3+则对西番莲果皮色素Ⅰ有明显的不良影响。该色素对耐强光、高温、还原剂、氧化剂和NO2等能力较差;漂白剂对色素溶液有明显漂白作用。

Abstract: The stability of pigmentⅠ from Passiflora edulis Sims’seedcase was investigated in this study. The results showed that the pH has obvious effects on the pigmentⅠstability. In the range of pH 1~4 there is little effect, but the metallic ions such as Cu2+ and Al3+ can strengthern the pigment color. However, Fe3+ has severe undesirable effect, changing the colorⅠinto some other color. It was found that the pigmentⅠis poor resistant to light, heat, reduct, oxide and NO2 . Bleacher can bleach the pigment Ⅰ.The results showed that the pigmentⅠ is worth of exploiting and utilizing. It may be used as one of the resources of natural edible pigment.
