摘要： Goji (Lycium barbarum L.) leaf tea (LBLT) has gained popularity among consumers owing to its pleasant aroma. Selecting optimal Goji cultivars for tea processing is critical for enhancing the quality of LBLT. This study investigated the aroma characteristics of Goji leaf white tea (LBLWT) and green tea (LBLGT) prepared from 25 Goji lines. LBLWT emitted woody, floral and fruity aromas, while LBLGT exhibited a distinct roasted corn aroma. The integrated application of variable importance in projection, odour activity value and partial least-squares regression analyses led to the identification of key aroma compounds, whose metabolic pathways were also illustrated. Using multi-criteria evaluation methods, excellent Goji lines suitable for processing LBLWT (Z20, Z48 and N1) and LBLGT (Z85, Z20, N1 and Z68) were screened. This study took the lead in adopting multi-criteria evaluation methods, screening high-quality Goji lines and providing theoretical basis for high-quality LBLT processing.
