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^＋、Fe^2＋、Fe^3＋、Mg^2＋、Zn^2＋、Cu^2＋、Al^3＋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；Mg^2＋、Fe^2＋、Fe^3＋、Zn^2＋、Cu^2＋、Al^3＋、氧化剂（H2O2）、还原剂（Na2S2O3）及碱性环境对色素有不良的影响。[著者文摘]

Abstract:
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.[著者文摘]
