| Abstract: | Aroma components in seven kinds of pears were investigated.Aroma components in pear were determined and analyzed by method of solid-phase microextraction (SPME) coupled with gas chromatography-mass spectrometry(GC/MS).Fourteen components including ten esters and four alkenes were identified from seven kinds of pears.Major aroma components in pear were esters,minor were alkenes acetic acid hexyl ester and alpha-farnsene were the two main constituents.It was cleared that aroma components of esters and alkenes should be a guideline for quality evaluation of pears. |
