| Abstract: | "The nutritional and volatile profiles of pulp and flavedo samples from four distinct local pummelo landraces ('Siji,' 'Pingshan,' 'Wendan,' and 'Guanxi') cultivated in Fujian province of China were investigated. 'Guanxi' pummelo exhibited relatively high contents of vitamin C (42.01 mg/100 mL) and phenols (360.61 mg/L) and displayed a robust antioxidant capacity (41.15 mg/100 mL). Conversely, the red pulp from 'Pingshan' demonstrated relatively high values of carotenoids (55.96 microg/g) and flavonoids (79.79 mg/L). Considerable differences were observed in volatile compositions between the two fruit tissues and among the four genotypes. A total of 166 and 255 volatile compounds were detected in the pulp and flavedo samples, respectively. Notably, limonene and beta-myrcene were identified as the principal volatile compounds in flavedo, whereas hexanal was highly abundant in the pulp of 'Siji,' 'Pingshan,' and 'Guanxi.' 'Wendan' displayed distinct separation from the other three pummelo cultivars in principal component analysis based on the pulp volatile compositions. This distinction was attributed to the higher number and content of volatile compounds in 'Wendan' pulp, particularly the remarkable enrichment of beta-myrcene. The newly characterized pummelo landraces and genotype/tissue-dependent variations in volatiles provide essential information for the genetic improvement of pummelo aroma, as well as for fruit processing and utilization" |
