白茶化学成分与风味科学
White Tea Chemistry and Flavor Science
白茶的核心化学成分：茶多酚(占干重15-30%)——贡献涩感和抗氧化活性；咖啡碱(2-5%)——苦味和提神；茶氨酸(1-3%)——鲜甜和放松；黄酮类(2-5%)——抗氧化、随陈化增加；可溶性糖(3-5%)——甜味和汤感厚度。白茶的'不炒不揉'工艺使这些成分保留率高于其他茶类。萎凋过程中，蛋白质分解为氨基酸、多糖分解为单糖，是白茶'越萎凋越甜'的化学基础。芳香物质中，芳樟醇及其氧化物是白茶'毫香'的主要来源。
Key white tea compounds: polyphenols (15-30% dry weight)—contribute astringency and antioxidant activity; caffeine (2-5%)—bitterness and alertness; L-theanine (1-3%)—sweetness and relaxation; flavonoids (2-5%)—antioxidant, increasing with aging; soluble sugars (3-5%)—sweetness and mouthfeel thickness. The 'no roasting, no rolling' craft preserves higher compound levels than other tea types. During withering, proteins break down into amino acids and polysaccharides into simple sugars—the chemical basis for 'sweeter as it withers.' Among aroma compounds, linalool and its oxides drive the 'downy aroma.'
