中文摘要：本研究采用HS-SPME-GC-MS技术分析了有机种植与普通种植方式下不同品种鲜橙中的风味物质，结果表明：各品种鲜橙在普通种植方式下的酯类化合物含量高于有机种植。另一方面，有机种植方式下与香叶基-二磷酸通路（橙花醇和香叶醇乙酸酯）相关的化合物及部分萜类化合物的含量更高。研究首次对不同种植方式下橙子的风味物质含量进行了比较。以通过挥发性物质组成对有机鲜橙进行鉴别为重点，综合应用了本地数据集、栽培方式和先进的分析工具进行分析。
外文摘要：A targeted approach using HS-SPME-GC-MS was performed to compare flavor compounds of 'Navelina' and 'Salustiana' orange cultivars from organic and conventional management systems. Both varieties of conventional oranges showed higher content of ester compounds. On the other hand, higher content of some compounds related with the geranyl-diphosphate pathway (neryl and geranyl acetates) and some terpenoids were found in the organic samples. Furthermore, the partial least square discriminant analysis (PLS-DA) achieved an effective classification for oranges based
on the farming system using their volatile profiles (90 and 100% correct classification). To our knowledge, it is the first time that a comparative study dealing with farming systems and orange aroma profile has been performed. These new insights, taking into account local databases, cultivars and advanced analytical tools, highlight the potential of volatile composition for organic orange discrimination.
