中文摘要: 以玫瑰茄的花萼为原料,通过气相色谱嗅闻技术筛选出11 种可能呈现与甜味感知相关的挥发性香气成分,包括己醛、糠醛、苯甲醛、1-辛烯-3-醇、辛醛、芳樟醇、壬醛、α-松油醇、癸醛、香叶基丙酮和橙花叔醇。由感官描述筛选出6 种甜味感知相关的香气成分,分别为糠醛、苯甲醛、芳樟醇、癸醛、香叶基丙酮和橙花叔醇,且除癸醛以外的5种香气成分在30 g/L 蔗糖溶液中均有显著增甜作用,其中芳樟醇的增甜效果最佳。通过气相色谱-质谱联用技术对玫瑰茄中香气成分进行定性定量分析。结果表明,玫瑰茄样品中香气成分达56 种,占峰面积的95.51%,其中醛类17 种、碳氢化合物10 种、醇类10 种、酯类8 种、酸类3 种、酮类4 种和其他化合物4 种。糠醛(12.64%)、苯甲醛(1.69%)、芳樟醇(1.75%)、癸醛(4.10%)、香叶基丙酮(1.36%)以及橙花叔醇(1.01%)的相对含量均高于1%。
Abstract:The gas chromatography/olfactometry-associated taste method was employed to screen the volatile aroma components that might present a sweet taste from the calyxes of roselle(Hibiscus sabdariffa Linn.).A total of 11 components were screened out,including hexanal,furfural,benzaldehyde,1-octen-3-ol,octanal,linalool,nonanal,α-pinoresinol,decanal,geranylacetone,and nerolidol.According to the results of sensory description,six aroma components related to sweetness perception were identified,which were furfural,benzaldehyde,linalool,decanal,geranylacetone,and nerolidol.Except decanal,the other five aroma components had a significant sweetening effect in 30 g/L sucrose solution,and linalool had the best sweetening effect.Furthermore,the aroma components in roselle were qualitatively and quantitatively analyzed by gas chromatographymass spectrometry.A total of 56 aroma components were detected in roselle,accounting for 95.51% of the peak area,including 17 aldehydes,10 hydrocarbons,10 alcohols,8 esters,3 acids,4 ketones,and 4 other compounds.The relative content of furfural(12.64%),benzaldehyde(1.69%),linalool(1.75%),decanal(4.10%),geranylacetone(1.36%),and nerolidol(1.01%)was higher than 1%.
