| 中文摘要: |
| 【目的】比较三个不同产地的赣南早脐橙果实品质，为赣南早脐橙的合理区划提供借鉴。【方法】测定了信丰、兴山和秭归三个产区赣南早脐橙的果实品质，利用气相色谱质谱联用（GC-MS）检测样品果实挥发性物质成分，并用主成分分析法进行香气品质的评价。【结果】三个不同产区的赣南早脐橙的果实品质没有明显差异。但不同地区的赣南早脐橙果皮和果肉中挥发性物质的种类和含量均存在一定的差异。兴山赣南早脐橙果皮挥发性物质总量（4220.37ug/g）和果肉挥发性物质总量（40.87ug/g）均最高。D-柠檬烯在赣南早脐橙果皮和果肉挥发性物质中含量最高。主成分分析表明，单萜类及烯萜类氧化衍生物挥发性成分的差异，形成不同产地赣南早脐橙的风味特征。通过主成分分析，能将不同产区的赣南早脐橙区分开。 |
| 英文摘要: |
| [Objective] The fruit quality of Gannanzao navel oranges（Citrus Sinensis Osbeck） from three different origins was compared in order to provide reference for the rational division of Gannanzao navel oranges. [Method]The fruit quality of Gannanzao navel orange from Xinfeng, Xingshan and Zigui was determined. Then the volatiles components in peel and pulp were detected by GC-MS, and the aroma quality was evaluated by principal component analysis. [Result] There was no significant difference in fruit quality among Gannanzao navel orange from three different producing areas. But the kinds and contents of volatiles compounds in the peel and pulp of Gannanzao navel orange were different in different regions. The total amount of volatiles in the peel (4220.37ug/g) and the total amount of volatiles in the pulp (40.87ug/g) of Xingshan Gannanzao navel orange were the highest. The content of D-limonene was the highest in the volatile substances in the peel and pulp of Gannanzao navel orange. The principal component analysis showed that the differences in the volatiles of monoterpenes and terpenoid oxidized derivatives formed the flavor characteristics of Gannanzao navel oranges in different origins. Through principal component analysis, Gannanzao navel oranges from different producing areas can be distinguished. |
