| 摘要: |
| 利用顶空固相微萃取（Head space solid phase microextraction,HS-SPME）和气相色谱-质谱联用技术（Gas chromatography/Mass spectrometry,GC/MS）对猕猴桃酒香气成分进行了分析鉴定。结果表明：①从猕猴桃酒中共分离鉴定出82种香气成分,其中新发现香气成分有邻苯二甲酸二丁酯（0.04%）、2-苯乙基月桂酸酯（0.01%）、棕榈酸乙酯（0.75%）、肉豆蔻酸乙酯（0.17%）、月桂酸乙酯（1.93%）、法呢醇（0.05%）、橙花叔醇（0.03%）共7种;②香气中相对含量较高的酯类有癸酸乙酯（8.52%）、丙酮酸异戊酯（7.51%）、乙酸乙酯（6.22%）、辛酸乙酯（6.00%）、乙酸苯乙基酯（3.61%）、月桂酸乙酯（1.93%）、乙酸己酯（1.28%）、己酸乙酯（0.92%）、乙酸异丁酯（0.87%）等;③香气中相对含量较高的醇类有2-甲基-1-丁醇（13.29%）、异丁醇（5.40%）、苯乙醇（3.18%）、己醇（0.79%）等;④香气中相对含量较高的脂肪酸类主要有辛酸（4.37%）、癸酸（3.99%）。此外,还检测出可能构成猕猴桃酒特征香气组分的α-松油醇、里哪醇等香气成分。 |

| Abstract: |
| The aroma components of kiwifruit wine were analyzed by gas chromatography mass spectrometry with head space solid phase microextraction，and 82 components were identified.The results showed as follow:① 7 aroma components including Dibutyl phthalate(0.04%),2 phenylethyl laurate(0.01%),Hexadecanoic acid ethylester(0.75%),Myristic Acid,ethyl ester(0.17%),Lauric acid,ethyl ester(1.93%),(E.E) Farnesol(0.05%) and Trans nerolidol (0.03%) were reported for the first time.②Esters in the main aroma components with higher relative content in kiwifruit wine included Decanoic acid,ethylester（8.52%）,Iso-amyl pyruvate（7.51%）,Ethyl Acetate（6.22%）,Ethyl-caprylate（6.00%）,Acetic acid,phenethyl ester（3.61%）,Lauric acid ,ethyl ester（1.93%）, Acetic acid ,hexyl ester（1.28%）, Hexanoic acid,ethylester（0.92%），and Acetic acid.2-methylpropyl ester（0.87%）.③Alcohol with higher content included 2-Menthyl-1-butanol（13.29%）,Lsobutyl-alcohol（5.40%）,Phenylethyl Alcohol（3.18%）and Hexyl alcohol（0.79%）.④Fatty acid consisted of Octanoic Acid（4.37%）,and Decanoic acid（3.99%）.And some possible characteristic of aroma components of kiwifruit wine were detected such as p-Menth-l-en-4-ol and Linalool etc. |
