摘要
以茶渣为试验原料,利用传统的碱法提取茶渣中非水溶性蛋白。主要研究了提取温度、提取时间、碱液浓度以及料液比等单因素对蛋白提取率的影响,正交试验结果表明,碱法提取茶叶蛋白的最佳条件为,料液比1∶30(g/mL),时间60 min、温度80℃、碱液浓度0.3 mol/L。此时蛋白的提取率达77.35%,该提取工艺参数具有较高的提取率。
Extracting tea-protein from tea residues by using alkali extraction was investigated in this paper: extraction temperature,extraction time,solid to water ratio and alkali concentration on extraction rate of protein were tested.Orthogonal test results showed that: the optimum technology was: extraction temperature(80 ℃),extraction time(60 min),solid to water ratio 1 ∶ 30(g/mL) and alkali concentration(0.3 mol/L).The extraction rate of tea protein was about 77.35 % under above conditions.This extraction process parameters have higher extraction rate.
