摘要
利用顶空固相微萃取法提取大青皮甜石榴整体果实、石榴皮和石榴籽汁的芳香物质,气相色谱-质谱联机定性定量分析,检测香气组分。石榴香气组分中以醛类和醇类为主,在石榴整体果实中占总峰面积的78.32%和14.52%,在石榴皮中占89.88%和4.70%,在石榴籽汁中占82.15%和9.78%。石榴中共检测出77种香气组分,其中石榴果实、果皮和籽汁中分别检测出42种、39种和43种。香气成分中共有的成分为18种,在果实、果皮和籽汁中分别占总峰面积的94.62%、95.59%和93.76%。2-己烯醛、己醛、3-己烯醛、(E,E)-2,4-己二烯醛为石榴的主要香气成分,在果实、果皮和籽汁分别占78.27%、89.78%和81.79%。结果表明,石榴香气组分以C6醛和醇为主,石榴不同部分香气组分差异也主要表现在C6醛和醇含量的差异上。
The aromatic substances in fruit, pericarp, and pulp of pomegranate were extracted with headspace solid phase micro extraction and determined by GC/MS. The main aromatic substances in the fruit were aldehydes and alcohols, and their contents were respectively 78.32% and 14.52% in the entire fruit, 89.88% and 4.70% in the pericarp, and 82.15% and 9.78 % in the pulp. Seventy-seven kinds of the aromatic substances were determined in pomegranate fruit, among which 42, 39, and 43 kinds of substances were respectively found in the entire fruit, pericarp and pulp. There were 18 aromatic substances shared with all the three parts of the fruit and the substances were respectively 94.62%, 95.59% and 93.76% of the total aromatic substabces in the entire fruit, the pericarp and the pulp. The main aromatic substances of pomegranate were 2-Hexenal, Hexanal, 3-Hexenal, and ( E, E)-2, 4-Hexadienal and their relative contents were 78.27% , 89.78% , 81.79% in the entire fruit, pericarp and the pulp, respectively. The results indicated that the main aromatic substances in the pomegranate fruit were aldehydes and alcohols which have 6 C. The various fragrances in different parts of the fruit were determined by the composition of the 6 C aldehydes and alcohols.
