Comprehensive evaluation of aroma and taste properties of different parts from the wampee fruit

Abstract

Wampee is a tropical fruit having high medicinal value. To fully realize the fruit’s potential, it is essential to reveal the flavor characteristics. In this study, a comprehensive analysis of the aroma and taste profiles of different parts from the wampee fruit was conducted. The aroma profile was analyzed by E-nose, and 67 volatile components were identified through HS–SPME–GC–MS. Among them, 11 were considered as crucial compounds. Additionally, 42 volatile components were identified by HS–GC–IMS, with 22 compounds showing a variable importance in projection scores greater than 1.0. Moreover, the taste profile and representative compounds were analyzed by E-tongue and HPLC, and 12 compounds were considered as important taste contributors based on taste activity value. These findings shed light on the various compounds responsible for the unique aroma and taste of the wampee fruit, providing theoretical foundation for exploring ways for its comprehensive utilization and development.
