摘要
为了探讨适合茶叶渣的色素提取工艺,首先,通过光波扫描寻找适宜的可见光检测波长;随后,设计单因素实验找出最佳的温度、料液比、时间和浓度;最后,利用L_(9)(3^(4))正交试验优化提取工艺。结果发现,茶叶渣色素最大吸收波长为665 nm;单因素试验发现提取茶叶渣色素最佳效果为:温度80℃、料液比1:10、提取时间120 min和乙醇浓度80%;通过正交实验优化后,提取茶叶渣最优工艺为85℃的提取温度、1:5(g/mL)的料液比、135 min的提取时间和100%的提取液浓度,并检验试验也证实该条件下茶叶渣色素提取效果最佳。
In order to explore the suitable pigment extraction process for tea residues, firstly the suitable visible light detection wavelength was searched by light wave scanning, then a single factor experiment was designed to find the best temperature, material-liquid ratio, time and concentration, L_(9)(3^(4)) orthogonal experiments were used to optimize the extraction process.The results showed that the maximum absorption wavelength of tea residue pigment was 665 nm, the single factor experiment found that the best effect of extracting tea residue pigment was as follows: temperature was 80 ℃,solid-liquid ratio was 1:10,extraction time was 120 min, and ethanol concentration was 80%.After the optimization of the experiment, the optimal process for the extraction of tea residues was as follows the extraction temperature was 85 ℃,the ratio of solid to liquid was 1:5(g/mL),the extraction time was 135 min and the concentration of the extraction liquid was 100%.The test also confirmed this condition.The best results were obtained from the extraction of pigment from tea residues.
