Abstract:

In this paper the extraction of Rubus biflorus Buch aroma compounds with three coating materials of solid-phase micro-extraction（SPME） fiber and the automatic identification method for gas chromatography/mass spectrometry（GC/MS） data were researched. The aim of this experiment was to summarize a simple，accurate method for quality breeding and processing of strawberry. The aroma compounds in Rubus biflorus Buch were detected by SPME-GC/MS. A total of 27 compounds were identified by using 3 fiber heads. The major constituents were alcohols，esters，carboxylic acids，ketones and terpenes，with the proportions of 40.7%，29.6%，18.5%，7.4%，3.7%，respectively. The 85 μm PA fiber showed high sensitivity and selectivity for the determination of aroma compounds. 3 kinds of fiber hends were found nerol，geraniol，neral and geranial，geranic acid and lauryl alcohol of 6 kinds of aroma components. Nerol，nerol，geraniol，geranial and geranic acid content is relatively high，is the characteristic aroma components of the Rubus biflorus Buch fruit. 85 μm PA fiber is suitable for the extraction of aroma compounds of Rubus biflorus Buch. And provide a simple and accurate method for the study of Rubus biflorus Buch quality breeding and deep processing.
