采用振荡技术,研究了黑茶-丙酮-溴酸钾-硫酸锰-硫酸的振荡反应新体系的振荡图谱.测定了不同浓度,不同温度下黑茶的振荡反应图谱,考察了添加物碘酸钾对振荡行为的影响,并探索了黑茶的最佳饮用条件.实验结果表明:黑茶振荡体系诱导期表观活化能为Ein=96.919 kJ/mol,振荡周期平均活化能为Ep=64.275 kJ/mol,其最佳饮用条件为浸泡温度100℃、浸泡时间8 min、采用蒸煮茶叶或泡黑茶粉末的方式.这为黑茶制备黑茶饮料以及将黑茶入药的研究提供了一定的指导意义.

The oscillation reaction in dark tea -Acetone-KBrO3-MnSO4-H2SO4 was studied by means of oscillating technology. Secondly, The oscillating behaviors of dark tea were determined at different concentrations and temperatures. Further, The effect of potassium iodate on the oscillating reaction and the best conditions to drink dark tea were studied. The results showed that the apparent activation energys for induction phase was 96.919 kJ/mol, and oscillating period was 64.275 kJ/mol. And its optimum drink conditions are as follow： soaking temperatur...
