Study on fruit volatiles of strawberry varieties from China, Japan and the United States
Gas chromatograph-mass spectrometer (GC-MS) was applied to detect fruit volatiles of 9 strawberry varieties from China, Japan and the United States. A total of 68 volatiles were identified in tested materials. The results showed that there were no significant differences in total number of volatiles and number of ester, aldehyde, terpene, ketone, furan, and lactone among Chinese (CN), Japanese (JP), and American (AM) varieties. Average 8.0 alcohols were identified in JP varieties and it was significantly more than CN and AM varieties. Remarkable more acids were separately found in JP varieties and AM varieties. CN varieties had notably higher percentage of aldehyde in total volatiles than JP and AM varieties, however, the average contents of ketones and acids in JP varieties were significantly higher than those of CN and AM varieties. There were average 11.0 prominent compounds found in CN varieties, while average 11.3 and 15.0 compounds in JP and AM varieties, respectively. The average content of 2-Hexenal in CN varieties was significantly higher than other variety groups, simultaneously AM varieties had the lowest content. Butyl acetate, hexyl acetate and 1-methylethyl butanoate were only prominent in AM varieties, however, only the content of hexyl acetate and 1-methylethyl butanoate was significantly higher than CN and JP varieties, respectively. The average content of hexanoic acid in JP varieties showed notably higher than other varieties.
