摘要: 通过向稳态体系“溴酸钠-硫酸锰-硫酸-丙酮”中加入不同的茶饮料,获得来自不同产家、不同品种的茶饮料的非线性化学指纹图谱,并对其进行相似度计算。非线性化学指纹图谱的直观信息、定量信息、相似度计算结果都能很好的将冰红茶从其他茶饮料中鉴别出来,且振荡寿命与检测用量有很好的函数关系。通过比较不同掺水量的茶饮料的非线性化学指纹图谱的参数信息,对茶饮料的质量进行评价。非线性化学指纹图谱技术可为茶饮料的鉴别和评价提供一种新的方法。

Abstract: Nonlinear chemical fingerprint based on chemical oscillatory reaction is a novel technology to analyze samples from the nonlinear chemical viewpoint. Different kinds of tea beverages from different manufacturers were added to the steady system sodium bromate-manganese sulphate-sulphuric acid-acetone to obtain their nonlinear chemical fingerprints, and the similarity was calculated. Uni-President ice black tea could be differentiated from other tea beverages by the intuitionistic information, quantitative information, and similarity calculation. And the function between oscillatory life and determining dosage was good. The quality of the tea beverage was evaluated by comparing the nonlinear chemical fingerprint parameter information of the ice black tea with different amounts of adulterated water. Therefore, nonlinear chemical fingerprint can provide a novel strategy to identify and evaluate tea beverages.

Key words: tea beverages, identification and evaluation, chemical oscillatory reaction, nonlinear chemical fingerprint
