摘要: 采用气相色谱-质谱-嗅闻仪(gas chromatography-mass spectrometry-olfactometer,GC-MS-O)对新鲜沙棘果汁和沙棘原浆中的气味化合物进行鉴定,分别在新鲜沙棘果汁和沙棘原浆中鉴定出39和36种气味化合物。进一步发现己酸乙酯、2-甲基丁酸乙酯、3-甲基丁酸乙酯和异戊酸异戊酯具有较高的香气稀释(flavor dilution,FD)因子,确定是新鲜沙棘果汁中的关键气味化合物。另外,巴氏杀菌之后的沙棘原浆中果香酯类气味化合物的含量显著降低。通过感官评价和电子舌分析发现沙棘原浆的甜度和整体口感要优于新鲜沙棘果汁。相比较新鲜沙棘果汁,沙棘原浆中维生素C和总黄酮的含量明显降低,表明巴氏杀菌会降低沙棘果汁的营养品质。研究成果可以为沙棘产品的风味及营养品质优化提供理论参考

Abstract: Identification of odor compounds in fresh sea buckthorn juice (FSBJ) and sea buckthorn pulp (SBP) was performed by gas chromatography-mass spectrometry-olfactometer (GC-MS-O). A total of 39 and 36 odor compounds were identified in FSBJ and SBP, respectively. Further found that ethyl hexanoate, ethyl 2-methylbutyrate, ethyl 3-methylbutyrate, and 3-methylbutyl 3-methylbutanoate had high flavor dilution (FD) factors and were identified as the key odor compounds in FSBJ. In addition, the content of fruity esters odor compounds was significantly reduced in SBP after pasteurization. Taste sensory evaluation and electronic tongue analysis revealed that the sweetness and overall taste of SBP was superior to that of FSBJ. The content of vitamin C and total flavonoids in sea buckthorn pulp was significantly lower compared to FSBJ, indicating that pasteurization reduces the nutritional quality of FSBJ. The results of the study can provide theoretical references for flavor and nutritional quality optimization of sea buckthorn products.

Key words: sea buckthorn, odor compounds, flavor dilution factor, electronic tongue, vitamin C
