Abstract

The aim of this study was to test the effects of film mulching treatment on aroma components of pineapple fruits. In this present study, the pineapple fruits of treatment and control (open field) were harvested twice (in winter and summer, respectively) to detect the aroma components. The results indicated that esters and alkenes were the main aroma components of both treatment and control pineapple fruits. There were more kinds of esters with higher total relative contents detected in the treatment fruits both harvested in winter and summer. There were fewer kinds of alkenes with lower total relative contents detected in the treatment fruits harvested in summer. There were equal kinds of alkenes detected in both treatment and control fruits harvested in winter. But the total relative content of alkenes of treatment fruits harvested in winter was lower than that of control. There was one ester containing sulfur, propanoic acid, 3-(methylthio)-, methyl ester with relative content of 1.40%, detected in the treatment fruits harvested in winter. No ester containing sulfur was detected in the control fruits harvested in winter. In the treatment fruits harvested in summer, two esters containing sulfur, propanoic acid, 3-(methylthio)-, methyl ester (2.60%) and 3-(methylthio) propanoic acid ethyl ester (1.46%) were detected. There was only one ester containing sulfur, propanoic acid, 3-(methylthio)-, methyl ester (3.01%) was detected in the control fruits harvested in summer.
