摘要:

【目的】 通过分析不同黄瓜种质资源的营养品质与风味物质等果实品质特征,并关联人体感官评价,为科学评判黄瓜果实品质提供依据。【方法】 以天津黄瓜研究所提供的果实感官品质存在较大差异的12个品系(种)为研究材料,通过测定不同黄瓜果实中的可溶性糖含量、可溶性固形物含量、可滴定酸含量等营养品质指标,果实风味物质总量及(E, Z)-2, 6-壬二烯醛和(E)-2-壬烯醛等风味物质含量,并对黄瓜果实甜味、水分、脆度、香气、涩味、苦味等6个维度进行人体主观感官评鉴,基于感官评价结合营养品质特征与风味物质特性综合关联分析黄瓜果实品质。【结果】 黄瓜果实感官评价中非涩味与甜味两个维度的权重赋值分别为27.12%和25.49%,其余香气、脆度、非苦味、水分4个维度的权重在10.59%—12.51%,而6个维度赋值越高,其感官品质综合评分越高。黄瓜果实感官评价中甜味、水分、脆度、香气、非苦味等与果实可溶性固形物含量、可溶性糖含量、抗坏血酸含量(极)显著相关。黄瓜风味物质(Z)-6-壬烯醛与感官评价中甜味、香气、水分、非苦味、非涩味等呈现极显著或显著相关,同时也与可溶性固形物含量、可溶性糖含量、抗坏血酸含量分别具有极显著正相关关系。黄瓜风味物质(E, Z)-2, 6-壬二烯醛与(E)-2-壬烯醛的比值与感官评价中非涩味呈显著相关,即该比值越大,果实涩味越弱。参试黄瓜品系(种)中,L2品系(种)的果实可溶性糖含量、可溶性固形物含量、抗坏血酸含量、固酸比均普遍高于其他品系(种),感官评价中甜味、脆度、香气、水分、非苦味和非涩味6个维度的总分值最高,果实品质最优。【结论】 黄瓜果实可溶性固形物含量、可溶性糖含量、抗坏血酸含量、(Z)-6-壬烯醛含量、(E, Z)-2, 6-壬二烯醛/(E)-2-壬烯醛比值可作为快速评价黄瓜感官品质与风味品质的指标。

Abstract:

【Objective】 This study aimed to establish a scientific framework for cucumber fruit quality evaluation by integrating the analysis of nutritional traits and flavor compound profiles across diverse germplasm resources with human sensory evaluation. 【Method】 Twelve cucumber lines/varieties with significant sensory variation (provided by Tianjin Cucumber Research Institute) were investigated. The measurements included three parts: first, nutritional traits of fruits, such as soluble sugar content (SSC), total soluble solids (TSS), and titratable acidity (TA); second, flavor compound content in fruits, such as total volatiles and key aldehydes [(E, Z)-2, 6-nonadienal, (E)-2-nonenal, (Z)-6-nonenal]; third, sensory evaluation of fruit quality, such as sweetness, juiciness, crispness, aroma, non-astringency, and non-bitterness. An integrated correlation analysis was performed to link sensory attributes with physicochemical profiles. 【Result】 In the sensory evaluation, non-astringency and sweetness had the highest weighting coefficients (27.12% and 25.49%, respectively), while the other four attributes (aroma, crispness, non-bitterness, and juiciness) ranged from 10.59% to 12.51%. Higher scores across these six dimensions indicated superior overall sensory quality. Furthermore, sweetness, juiciness, crispness, aroma, and non-bitterness of cucumber fruit sensory evaluation were (extremely) correlated with the SSC, TSS content and ascorbic acid content. In addition, cucumber flavor compounds (Z)-6-nonenal content showed significant correlation with sweetness, aroma, juiciness, non-bitterness and non-astringency in sensory evaluation, and it also had extremely significant positive correlation with the SSC, TSS and ascorbic acid content, respectively, while the ratio of cucumber flavor compounds (E, Z)-2, 6-nonadienal to (E)-2-nonenal was significantly correlated with non-astringency. Among the different cucumber varieties tested, line L2 generally exhibited higher levels of fruit SSC, TSS and ascorbic acid content, as well as the ratio of soluble solid content to titratable acid compared with the other lines. It also achieved the highest composite score across all those six sensory attributes. Consequently, line L2 demonstrated superior overall fruit quality. 【Conclusion】 The SSC, TSS, ascorbic acid content, (Z)-6-nonenal content, and the ratio of (E, Z)-2, 6-nonadienal to (E)-2-nonenal content of cucumber fruits could serve as effective indicators for the rapid evaluation of sensory and flavor quality.
