【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（p H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。更多还原

【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 （p H 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.更多还原
