Evaluation of Dark Tea Processing Suitability in 11 New Low-fluorine Tea Plant Strains
摘要
Abstract
Tea plant variety is a key factor determining tea quality,as the morphological characteristics and internal components of fresh leaves from different varieties make them suitable for processing into different types of tea.To breed new tea plant varieties suitable for dark tea production and establish suitability evaluation indicators,the fluorine content of 117 hybrid tea plant new strains was measured,from which 11 low-fluorine tea plant new strains were screened.The main biochemical components of these 11 low-fluorine tea plant new strains were determined,and sensory evaluations were conducted on the dark rough tea made from them.Significant difference and correlation analyses were performed to provide support for the selection of tea plant varieties suitable for dark tea processing.The results showed that the fluorine content of the 11 screened tea plant new strains ranged from 41.06 to 148.70 mg/kg,water extract content from 28.78%to 35.02%,tea polyphenol content from 11.93%to 15.50%,free amino acid content from 3.56%to 5.66%,caffeine content from 1.41%to 2.65%,catechin component content from 10.14%to 14.25%,cellulose content from 8.14%to 20.26%,and lignin content from 19.69%to 28.85%.Four strains received higher sensory evaluation scores than the control.Based on comprehensive comparison of fluorine content,biochemical component content,and sensory evaluation results,two low-fluorine high-quality dark tea plant new strains were preliminarily selected.Correlation analysis indicated that water extract,tea polyphenols,caffeine,and catechin components can serve as indicators for dark tea suitability,while the tenderness represented by cellulose and lignin content is also a major reference indicator for screening dark tea-suitable varieties.关键词
