摘要:

利用固相微萃取技术(solid phase micro extraction,SPME)与气相色谱- 质谱(gas chromatography-mass spectrometry,GC-MS)相结合对1-methylcyclopropene(1-MCP)处理南果梨20℃贮藏香气成分进行研究。结果表明:南果梨香气成分的释放与果实的后熟程度有很大的关系,总体上呈现先上升后略下降的趋势;1-MCP 处理延长了南果梨20℃贮藏期,但减少了香气成分种类;处理组检出果实香气的种类比对照组减少了27.8%,其中酯类香气种类比对照果减少了31.3%。

Abstract:

The fruit aroma components of Nanguo pears with 1-methylcyclopropene (1-MCP) treatment during storage at 20℃ were determined by solid phase micro-extraction (SPME) and gas chromatography-mass spectrometry (GC-MS). Results showed that the release of fruit aroma components had close correlation with fruit post-ripening degree, which exhibited a trend of initial increase and final decrease. The 1-MCP treatment could extend the shelf life time of Nanguo pears during storage at 20℃, while reduced the quantity of fruit aroma components. Compared with the fruits without 1-MCP treatment, the quantity of total fruit aroma components and esters aroma components decreased by 27.8 % and 31.3%, respectively.

Key words: Nanguo pear, fruit aroma component, 1-methylcyclopropene (1-MCP) treatment, solid phase microextraction(SPME), gas chromatography-mass spectrometry (GC-MS)
