| 中文摘要: |
| 研究采用热脱附-气相色谱-质谱（TD-GC-MS）对甘肃陇南生产的6个单品种初榨橄榄油的挥发性组分及多酚含量进行测定，并对6个单品种初榨橄榄油挥发性组分及多酚含量与其感官属性的关系进行分析。结果表明：鉴定出22种挥发性组分；甘肃陇南各单品种初榨橄榄油的活体香气主要呈现果味，C6醛醇类物质对初榨橄榄油果味有积极影响；6个单品种初榨橄榄油中多酚含量（401.77~780.34 mg/kg）较高，多酚类物质对橄榄油苦味的影响较大；辛辣味的来源则有待进一步研究。 |
| 英文摘要: |
| Volatile components and polyphenols content of six single varieties of virgin olive oils in Gansu Longnan were determined by thermal desorption -gas chromatography-mass spectrometry, and the relationships between volatile components and polyphenols content with sensory attributes of six single varieties of virgin olive oils were analyzed. The results showed that 22 volatile components were identified. Living aroma of the six single varieties of virgin olive oils in Gansu Longnan was mainly fruit fragrance, and the content of C6 aldehydes and alcohols had positive impact on olive oil fruit fragrance. The polyphenols contents of the six single varieties of virgin olive oils were high（401.77-780.34 mg/kg）,which had larger effect on bitter taste of olive oil, while the hot taste source could be further studied. |
