Application of HS-SPME and GC-MS analysis of trace volatile components in the liquor fermented grains

Abstract

Abstract:

Application HS-SPME and GC-MS method extraction the volatile components of the solid phase micro of the Chinese white wine fermented grains. Different types of SPME fibers, the water bath temperature, ultrasonic extraction time, and sample extraction on the extraction efficiency of trace volatile components. The results showed that the optimum condition for 65μm the PDMS / DVB SPME fibers, water bath temperature is 60℃, extraction without ultrasonic and the amount of fermented grains powder 10g. Throughout the fermentation process, this method detected 105 kinds of trace volatile components from fermented grains ,and we get the variation of the number and relative content of volatile substances species over time.
