Study on the content of wax oil chlorophyll and preparation technology of sodium copper chlorophyll

基于蜡油重要利用价值，优化蜡油叶绿素提取条件，分析蜡油叶绿素含量，设计酸化铜代、中和成盐二步法制备蜡油叶绿素铜钠工艺，并实时分析工艺效果，对蜡油叶绿素铜钠产品质量进行评价。低温（-10℃）条件下，料液比1：20—22（g：mL），以无水乙醇为溶剂萃取蜡油叶绿素为最佳萃取条件；蜡油叶绿素含量为3．0％；经酸化铜置、中和成盐二步工艺可有高效制备蜡油叶绿素铜钠，工艺产率达63．0％，产品各项重要指标符合国家标准。蜡油叶绿素含量丰富，具有开发利用价值。

Because of the important applications, the chlorophyll of wax oil was studied in this paper. The extraction condition of the wax oil chlorophyll was explored, and the content of wax oil chlorophyll was detected. Two step preparation process of the sodium copper chlorophyll was designed including acidification and copper replacement, neutralization and salt formation. The effects of preparation process were analyzed in real-time. The product quality was evaluated based on national standard. The results showed that the wax oil chlorophyll was efficiently extracted by absolute ethyl alcohol under the low temperature condition at -10 ℃ with ratio of material to solvent at 1：20-22 （m/V）. And the content was about 3% （g/g）. The wax oil sodium copper chlorophyll was successfully prepared using the above preparation process. And the yield of the sodium copper chlorophyll reached to 63.0% （g/g）. The quality evaluation results showed that some important quality factors met with the national standards. Wax oil has the great economic value because of the abundant chlorophyll. The preparation process of the sodium copper chlorophyll has the industrial development prospect duo to the simple, efficient yield and excellent product quality.
