Abstract
ABSTRACT This study investigated the effects of different shelter coverings (arched-shelter and umbrella-shelter) on the volatile components of sweet cherry mature fruits in rainy areas, and the postharvest quality of these fruits during storage at room temperature. A total of 68 volatile compounds were identified and semiquantified in mature fruits. Aldehyde compounds were the most abundant, followed by alcohols. Benzyl alcohol, acetaldehyde, 2-methyl-propanal, hexanal, (E)-2-hexenal and benzaldehyde were the major volatiles, and the proportions of these compounds were greatly affected by different shelter coverings. With the extension of the storage period, the color parameters (L*, a* and b*), texture parameters (hardness, springiness, chewiness, resilience, skin strength and flesh firmness) and titratable acidity of the fruit rapidly decreased. The total soluble solid content and weight loss of the fruit gradually increased. Principal component analysis indicated that the sweet cherry fruits from the arched-shelter had the best quality and the longest shelf life.
