Volatile Flavor Components in Bogyojosaeng and Suhong Cultivars of Strawberry (Fragaria ananassa Duch.)

Volatile flavor components of two strawberry (Fragaria ananassa Duch.) varieties, Bogyojosaeng and Suhong, ere extracted by SDE(Simultaneous steam distillation and extraction) using a mixture of n-pentane and diethylether (1:1, v/v) as an extract solvent. Analysis of the concentrate by capillary gas chromatography and gas chromatography-mass spectrometry led to the identification of 146 and 153 components in Bogyojosaengand Suhong respectively. There were 49 esters, 25 alcohols, 20 ketones, 24 aldehyds, 6 acids, 9 terpenes and terpene derivatives, 2ethers, 11 unknowns and miscelaneous in Bogyojosaeng and 67 ethers, 9 unknowns and miscellaneous in Suhong. Among these, (E)-2-hexenyl acetae (4.56%) in Bogyojosaeng and (E)-nerolidol (12.38%) in Suhong were major compounds and aceticacid, (E)-2-hexenal, hexyl acetate, ethyl acetate, ethyl butanoate, methyl butanoate, ethyl hexanoate and ${\gamma}$-dodecalactone were the main components in each sample, though there were several differences in composition and threshold of volatile compounds. Total contents of volatile components isolated and identified in Bogyojosaeng an Suhong were 9.010 and 12.527 mg/kg, respectively.
