| 摘 要： | 通过正交试验研究柏树叶中叶绿素浸提的最佳工艺条件,经过皂化、酸化、锌代及其成盐反应制备叶绿素锌钠盐,并对其稳定性进行研究。结果表明,柏树叶叶绿素的最佳浸提工艺条件为,乙醇浓度100%,浸提时间70 min,料液比为1∶20,温度控制在60℃。而其制备的叶绿素锌钠盐水溶性较好,耐热性、耐氧化还原性较好,但在光照条件下,稳定性差。常用的食品添加剂和一些金属离子对叶绿素锌钠盐的稳定性几乎没什么影响,Cu2＋、Fe3＋对叶绿素锌钠盐的稳定性有较大的影响。

| Abstract: | The optimum extraction method and conditions of chlorophyll from cypress were determined by orthogonal experiments.Sodium zinc chlorophyllin was prepared from the chlorophyll extracted through the processes of saponification,acidification,zinc substitution and its stability was investigated.The optimum extraction method and conditions were 100% of alcohol,70 min for extracting time,1：20 to the ratio of solute to solvent,and 60 ℃.The product had high water-solubility,thermal stability,and high resistance abilities to oxidants and reducers,but it was significantly faded down under sunshine.Moreover,it would not be influenced by some common food additives and metal-salts.However,it would be influenced by Cu2＋ and Fe3＋. |
