Abstract
ABSTRACTThe relationship between aroma and volatile composition of McIntosh apples was investigated. Significant correlations were found between aroma qualities determined organoleptically by a trained panel and by GLC. Unripe apples contained low levels of all volatiles and exhibited grassy and green aroma notes. C‐6 aldehydes correlated with overall aroma intensity, ripeness, and fruity and aromatic notes. Esters correlated with a cheesy aroma note. Overripeness correlated with esters and total peaks in unstored but not in stored apples. The GLC peak groups which previously were found to correlate with physical and chemical properties related to maturity in unstored McIntosh apples also correlated with aroma.
