Identification of discriminating chemical compounds in banana species and their odor characterization using GC-MS, statistical, and clustering analysis

The study aims identification of discriminating chemical constituents in the banana odor grown in Philippines and Ecuador using GC-MS characterization. Ester is recognized as a major chemical class in selected banana odor. Odors discriminating compounds like, 2-hexenal, ethyl acetate, and hexanoic acid, ethyl ester, etc. have been identified. Besides, other odors generating chemical compounds (alcohols, esters, aldehydes, and ketones) have been recognized. Furthermore, principal component analysis (PCA) and hierarchical cluster analysis were implemented to differentiate banana odors. PCA achieved 100% discrimination of selected bananas odors using the peak area information about recognizing chemical compounds. Odor identity and discrimination of selected bananas have been achieved successfully.

Automated summary

This study aims to identify discriminating chemical constituents in banana odors from the Philippines and Ecuador using GC-MS characterization. Ester is recognized as a major chemical class in selected banana odors, and compounds like 2-hexenal, ethyl acetate, and hexanoic acid, ethyl ester have been identified. Principal component analysis and hierarchical cluster analysis successfully differentiated the banana odors, achieving 100% discrimination of selected banana odors.
