distillate prepared from fresh apricots revealed (R)-gamma-decalactone, (E)-beta-damascenone, delta-decalactone, and (R/S)-linalool with the highest flavor dilution (FD) factors among the 26 odor-active compounds identified. On the basis of quantitative measurements performed by application of stable isotope dilution assays, followed by a calculation of odor activity values (OAVs), beta-ionone, (Z)-1,5-octadien-3-one
对由新鲜杏子制得的香精馏出物进行的香精提取物稀释分析表明,(R)-γ-癸内酯,(E)-β-大马烯酮,δ-十内酯和(R / S)-芳樟醇的风味稀释度最高(FD )鉴定出的26种气味活性化合物中的因素。在应用稳定同位素稀释测定法进行定量测量的基础上,然后计算气味活性值(OAVs),β-紫罗兰酮,(Z)-1,5-辛二烯-3-酮,γ-癸内酯,( E,Z)-2,6-壬二烯醛,芳樟醇和乙醛在OAVs> 100的情况下出现,特别是某些内酯,通常与杏香气有关,例如γ-十一内酯,γ-壬内酯和δ-癸内酯,显示非常低的OAV(<5)。通过将18种最重要的增香剂按新鲜水果中的浓度进行混合而制成的香气重组物,其总体香气与杏子非常相似。省略实验表明,杏子以前未知的成分,例如(E,Z)-2,6-nonadienalal或(Z)-1,5-octadien-3-one,是导致杏子香气的关键因素。
