Comparison of Chemical Composition Content of Different Dry Green Tea Leaves |
| |
| Abstract: | The chemical composition is the material basis of tea quality and different chemical composition is the cause of tea quality diversity. By analyzing the chemical composition of 14 samples of high quality dried green tea, the results show that there are abundant varieties of green tea in Our market. The chemical composition of tea have?great variation, which provides abundant materials for breeding different characteristic tea varieties. At the same time, correlation analysis showed that there was a significant correlation between the chemical components, indicating that the tea quality was complex, and the main factors affecting the quality should be identified in the breeding process. Through principal component analysis and cluster analysis, 14 samples can be divided into 4 categories, each with different characteristics. |
