Caqui cv. 'Mikado': Análise de compostos voláteis em frutos adstringentes e destanizados

Abstract

The objective of this study was to determine the volatile compounds in persimmon (Diospyros kaki) Mikado variety, astringent and astringency removal in two periods of storage, using solid phase microextraction (SPME, fiber DVB/CAR/PDMS) by gas chromatography mass spectrometry (GC-MS). The results showed differences in the volatile composition of astringent and astringency removal, with losses in both analyses. The removal of astringency with alcohol exposure increased the volatiles on day 1 after astringency removal. The volatiles from persimmon Mikado are mainly represented by terpene hydrocarbons, followed by straight-chain esters.
