东魁杨梅果实储藏期挥发性有机化合物成分的变化
Changes in volatile organic compounds (VOCs)during storage for Myrica rubra 'Dongkui'
摘要
Abstract
To determine changes in volatile organic compounds (VOCs) during storage for fruits of Myrica rubra, the composition and relative content of VOCs were analyzed using thermo desorption system-gas chromatogra-phy-mass spectrum (TDS-GC-MS). Results showed that M. Rubra emitted 62 types of VOCs, mainly as ter-penoids, esters, alcohols, aldehydes, and ketones, in which caryophyllene was the main compound with a relative content of 47.06%. The relative content of terpenoids showed a great difference during storage. After 4 days storage, the relative content of terpenoids was highest (95.91%) with the relative content of caryophyllene accounting for 62.74%. Measuring on the same day as picking, the relative content of aldehydes was highest with furfural and hexanal being the main components, but these decreased during storage. Alcohols first decreased and then increased with a relative content on the 6th day storage 5.80%.关键词
