中文摘要: 以西林火姜干姜片为原料,通过顶空固相微萃取(headspace solid phase micro-extraction,HS-SPME)结合气相色谱-质谱(gas chromatography-mass spectrometry,GC-MS)对萃取头种类、萃取时间和解析时间进行单因素优化,研究其挥发性香气成分。结果表明:3 g 西林火姜干姜粉采用100 μm PDMS 萃取头,萃取40 min,解析3 min 萃取挥发性香气成分效果最佳。在此条件下检测到干姜45 种香气成分,含量最高的是萜烃类,也有少量酯、酮、醛和醇等。主要的香气成分为姜烯、β-倍半水芹烯、(E,E)-α-法呢烯、β-红没药烯、α-姜黄烯、β-荜澄茄油烯、2-茨醇、α-柠檬醛、β-榄香烯。
Abstract:Volatile aroma components of the dried Xilin fire ginger slices were analyzed using headspace-solidphase microextraction(HS-SPME)in combination with gas chromatography-mass spectrometry(GC-MS).The SPME fiber type,extraction time,and desorption time were optimized using a single-factor optimization process.The highest extraction efficiency of the volatile aroma components was achieved with 3 g of dried Xilin fire ginger powder,a 100 μm polydimethylsiloxane extraction head,an adsorption time of 40 min,and a desorption time of 3 min. A total of 45 aroma components were detected,with terpenes being the most abundant;small amounts of esters,ketones,aldehydes,and alcohols were also present. The main volatile aroma components were (-)-zingiberene,β-sesquiphellandrene,(E,E)-α-farnesene,β-bisabolene,α-curcumene,βcubebene,2-endo-borneol,α-citra,and(-)-β-elemene.
