采用顶空固相微萃取对存放了30个月的早籼稻米及其72 h自然发酵液的挥发性成分进行提取,利用气相色谱-质谱对挥发性化合物进行分析,结合谱库检索技术、标准物色谱和参考文献对化合物进行鉴定,应用内标法定量,发现两者的主要挥发性成分均有乙醛(各为95.05,46.84 μg/mL)、2-羟基丙腈(43.59,30.79 μg/mL)、乙酸(17.77,59.36 μg/mL)和2-壬酮(78.27,92.38 μg/mL)等,自然发酵增加了二氧化碳(36.83 μg/mL)和4-甲氧基-1,3-苯二胺(0.67 μg/mL)等成分.

Headspace solid phase microextraction （SPME） technique was employed to extract volatile compounds from stored early indica rice and its 72 h natural fermented liquid, the early indica rice had stored for 30 months after harvested. Volatile compounds of the samples were isolated and identified successfully by capillary gas chromatography - mass spectrometry （GC - MS） coupled with NIST, GC chromatogram of reference samples and related hteratures. There are following same volatile components in both the stored early indica rice and the ferment...
