中文摘要: 大马士革玫瑰（Rosa damascene）精油提炼通常采用水蒸气蒸馏法，提取后会产生大量的花渣废水。通过前期采用大孔树脂吸附方法从花渣废水中回收得到了玫瑰色素，该文首次考察2种环境条件（pH值和温度）、4种常用食品添加剂（蔗糖、抗坏血酸、苯甲酸钠、Na2SO3）、1 种食品消毒剂（H2O2）、和 5 种金属离子（Fe3+、Cu2+、Al3+、Ca2+和 Mg2+）对色素稳定性的影响。结果表明，温度、蔗糖、Na2SO3、H2O2、苯甲酸钠和Mg2+对色素的稳定性无明显影响。玫瑰色素在中性和碱性环境下较稳定，在贮存过程中应尽量避免接触Fe3+、Al3+、Cu2+、Ca2+及强还原剂抗坏血酸。
Abstract:Steam distillation is usually used to extract essential oil from the flower of Rosa damascene，which would produce a large amount of waste water.In present study，the stability of the pigment recovered from waste water was firstly studied under different conditions，included two environmental conditions （pH and temperature），four common food additives （sucrose，Na2SO3，sodium benzoate and ascorbic acid），one food disinfectant （H2O2）and five metal ions （Ca2+，Mg2+，Fe3+，Al3+and Cu2+）.Experimental results showed that temperature，sucrose，Na2SO3，H2O2，sodium benzoate and Mg2+had no significant effect on the stability of the pigment.The pigment was stable in neutral and alkaline conditions.Fe3+，Al3+，Cu2+and Ca2+as well as ascorbic acid should be avoided during storage.
