5-dimethyl-3(2H)-furanone. Of the further odorants, 13 compounds have previously not been reported as tomato odorants. Although most of these showed lower FD-factors, in particular, the coconut/dill-like smelling wine lactone ((3S,3aS,7aR)-3a,4,5,7a-tetrahydro-3,6-dimethylbenzofuran-2(3H)-one) appeared with a quite high FD factor. In addition, a fruity, almond-like odorant (6) with an FD factor of 1024 was
通过溶剂萃取和随后的SAFE蒸馏,从意大利葡萄番茄中制得香气馏出物,产生强烈的总体香气。gc /嗅觉测定法和香气提取物稀释分析的应用揭示了44种气味活性化合物,其中42种可以被识别。对绿色,草绿色(Z)-3-己烯醛,金属味反式-4,5-环氧-(E)-2-癸烯,马铃薯样3-(甲硫基)确立了最高的气味活性值2048丙醛和焦糖状的4-羟基-2,5-二甲基-3(2 H)-呋喃酮。在其他增香剂中,以前没有13种化合物被报道为番茄增香剂。尽管其中大多数显示出较低的FD因子,尤其是椰子/莳萝味的葡萄酒内酯((3S,3a S,7a R)-3a,4,5,7a-四氢-3,6-二甲基苯并呋喃-2(3 H)-one)的FD系数很高。此外,还检测到FD系数为1024的果味杏仁状增香剂(6)。通过应用高分辨率质谱法和极性考虑因素,提出了甲基-2-乙氧基四氢吡喃异构体的结构用于6。合成了五个可能的异构体中的四个,即3-
