摘要
为揭示黄瓜果皮、果肉间香气差异及不同黄瓜品种果实香气特点,利用气相色谱-质谱联用技术对6个黄瓜品种进行芳香物质成分的检测分析。结果表明:从黄瓜果皮、果肉中分别检测出60种和47种芳香物质,主要包括醛类、醇类、酮类、酯类和烃类。醛类是黄瓜果肉的主要风味物质,含量高达总风味物质的83.78%~96.31%,显著高于果皮;醇类、酮类、酯类等主要分布在果皮中。综合比较黄瓜不同品种、不同部位的特征芳香物质差异可知,果实的黄瓜味主要来源于果肉,清香味来源于果皮;6个黄瓜品种香气风味物质存在明显差异,其中温室水果型品种相较于其他供试品种,含有较多的(E)-6-壬烯醛和壬醛,具有独特的水果香甜味道,‘南水8号’(E,Z)-2-6-壬二烯醛含量最高,黄瓜风味最为浓郁。
In order to reveal the aroma differences between peel and flesh of cucumber and the aroma characteristics of cucumber fruits in different varieties,gas chromatography-mass spectrometry(GC-MS)was used to detect and analyze the aroma components in the peel and flesh of cucumber.The results showed that 60 and 47 aroma compounds were detected in the peel and flesh of tested cucumber varieties,respectively,which mainly included aldehydes,alcohols,ketones,esters and hydrocarbons.Aldehydes were the main flavor compounds in flesh of cucumber,and its content was 83.78%-96.31%of the total flavor compounds,which was significantly higher than that in peel of cucumber.While other aromatic substances such as alcohols,ketones,and esters were mainly distributed in the flesh.By comprehensive comparison of the differences of characteristic aromatic compounds in the peel and flesh of cucumber,it suggested that the cucumber flavor of cucumber fruits mainly came from the flesh,while the fresh fragrance came from the peel.There were significant differences in aroma and flavor among the six cucumber varieties,among which the fruit type varieties for greenhouses contained more(E)-6-nonenal and nonenal than other tested varieties,and had unique flavor of sweet fruit.‘Nanshui No.8’had the highest(E,Z)-2-6-nonenal content,and the flavor of cucumber was the strongest among all tested varieties.
