Multivariate analysis of chemometric based aroma dynamics in small cardamom (Elettaria cardamomum Maton) during drying.

ABSTRACT: The aroma compositions and essential oil contents extracted from small cardamom (Elettaria cardamomum Maton) dried at three temperatures using a hot air convective dryer was studied by chromatographic methods. The major compounds in the dried samples were 1,8-cineole (7.23-11.76%) and α-Terpinyl acetate (61.65-68.19%) that were responsible for the specific aroma. The extracted essential oil was found to be majorly composed of alkenes (33-42%), alcohols (18-30%) and esters (18-22%) with acids, alkyls and ketones. The changes in esters and alcohols with drying time were more significant (p < 0.05) than acids, alkenes and aldehydes at all three temperatures. The data were analysed using Principal Component Analysis (PCA) and Hierarchical Cluster Analysis. The analyses ind
