摘　　要： 本文研究了大叶蛇葡萄色素热稳定性、光稳定性、耐氧化还原性和pH稳定性,并进一步探讨了食品中常见的金属离子K+、Na+、Fe2+、Fe3+、Mg2+、Zn2+、Cu2+、Al3+和常用添加剂对大叶蛇葡萄色素稳定性的影响。结果表明热、光照、K+、Na+、维生素C及苯甲酸钠对色素无不良影响;Mg2+、Fe2+、Fe3+、Zn2+、Cu2+、Al3+、氧化剂(H2O2)、还原剂(Na2S2O3)及碱性环境对色素有不良的影响。 Pigment was extracted from Ampelopsis Megalophylla Diels et. Gilp. The chemical properties of the pigment including thermo stability, photo stability, resistance to oxidation-reduction and the stability of pH value of pigment solution were examined. The major actions such as K ^＋ , Na ^＋ , Fe^2＋ , Fe^3＋ , Mg^2＋ , Zn^2＋ , Cu^2＋ , Al^3＋ and usual food additive were also investigated for pigment stability. The results showed： The pigment had a strong resistance to heat and light, K ^＋ , Na ^＋ , VC and sodium benzoate had no negative effects on the stability of the pigment. Mg^2＋ , Fe^2＋ , Fe^3＋ , Zn^2＋ , Cu^2＋ , Al^3＋ H2O2, Na2S2O3, and alkali was disadvantage to its stability.
