| Abstract: | The diversity of aroma volatile compounds from 12 pineapple varieties were studied. Cluster analysis and principal component analysis were used to evaluate the experimental results. A high variability of aroma volatiles compounds were found among 12 pineapple varieties. Cluster analysis showed that these pineapple varieties were separated into four groups when correlation coefficient distance was 19. Principal component analysis suggested 120 compounds identified could be simplified to 3 components including 27 compounds, and Mibao variety reached the highest comprehensive score. The results had a certain applied value for assessing aroma qualities and improving the breeding process of pineapple. |
