摘要
用直线和曲线模型,模拟分析了60个品种(系)鲜叶中的主要生化组分与绿茶感官。品质的关系,结果表明,水浸出物(We)、儿茶素(TC)和咖啡碱(Cf)与绿茶品质(GQ)的关系可用二次曲线模型(GQ=32.48+3.043We-0.0429We^2,GQ=84.5329+0.0463TC-0.0003 TC^2,GQ=48.57+18.3629Cf-2.2402 Cf^2)来模拟,茶多酚与绿茶品质之间也呈二次曲线关系,但以其对水浸出物的相对含量(Ph/We)来分析比绝对含量更适宜[GQ=80.23+0.3058 Ph/We-0.0037(Ph/We)~2],氨基酸(A)、酚氨比(P/A)和还原糖(S)与绿茶品质的关系宜用直线模型(GQ=79.94+2.3652A,GQ=87.88-0.2107P/A,GQ=87.5816-3.142S)来描述。
Relationship between the content of biochemical component in theshoot of the one bud & two or one bud & three and the quality ofgreen tea was simulated with linear and curve mathematical models.Results showed that the relationships between the water extract contentand the quality,between the catechin content and the quality,betweenthe Caffeine content and the quality,and between the polyphenol con-tent and the quality could be matched in a quadratic curve model'sway,while those between the amino acid content and the quality,between the value of polyphenols/amino acids,and the quality,andbetween the reducing sugar content and the quality in a linear model'sway
