The Optimization and HS-SPME/GC-MS Analysis in Pear Fruit

摘要

Solid-phase microextraction (SPME) is a rapid sample preparation in volatile analysis. The aromatic volatile compositions of 'Kuerle' were analyzed using SPME and gas chromatography-mass spectrometry (GC-MS). The effect of different types of fibers, extraction time, and extraction temperature on the volatile results were compared and discussed. The results were as followed. Results showed that 65um PDMS/DVB fiber had the best effect of extraction. The optimum factors such as extraction time and temperature were 45 min and 40°C.
