Volatiles Distinguishing the European 'Conference' and the Asian 'Yali' Pears Stored at Different Post-Harvest Temperatures
Original language description
A total of 124 identical volatile aromatic compounds were identified during storage of the European 'Conference' and the Asian 'Yali' pear cultivars in different temperature conditions. Only 5 volatiles were statistically differentiated in both cultivars by means of successive multinomial logistic regression: 3-methylbutan-1-al, 2-methylpropyl acetate, 2-methoxy-4-vinylphenol, ethanol, and eugenol. Significant statistical data obtained by sequential multinomial logistic regression developed by the principal component analysis (PCA) procedure and distinguishing the different 'Conference' and 'Yali' pears storage regimes were dimensionless in themselves. The PCA components were expressed as linear combinations of selected variables necessary to distinguish the cultivars. The eigenvalues of the first three PCA components differentiated the storage regimes. For each principal components were selected volatiles with a probability higher than 0.4. Combinations created from PCA components were shown using clusters distinguishing the pear storage conditions used. Analytical data from SPME-GC/MS such as concentration (ng kgMINUS SIGN 1) demonstrated multiple and order-of-magnitude differences between the 'Conference' and 'Yali' pears. The 'Yali' cultivar exhibited significantly higher concentrations of eugenol.
