对中、长保质期夏朗德哈密瓜的风味进行了比较。使用多因素分析将挥发性和半挥发性特征与感官数据相关联。收获时的成熟度对中等保质期水果的风味有重大影响。收获时成熟对长保质期基因型的影响要小得多。成熟的中等保质期水果中的酯和硫化合物含量更高。研究了在两种不同成熟度（未成熟和成熟果实）收获的夏朗德哈密瓜（中等保质期和长保质期）的两种基因型的风味特征。采用动态顶空萃取（DHE）、固相萃取（SPE）、气相色谱-质谱（GC-MS）和气相色谱-嗅觉/质谱（GC-O/MS）来测定挥发性和半挥发性化合物。定性描述分析（QDA）用于评估不同甜瓜的感官影响，并将感官数据与化学分析相关联。对于中等保质期基因型，成熟和未成熟的果实之间存在显着、一致和实质性的差异，较不成熟的果实具有绿色、黄瓜的特征，并且缺乏成熟果实的甜味、果味特征。然而，收获时的成熟度对长保质期甜瓜的影响要小得多，并且检测到的差异也较少。这些保质期长的瓜尝起来很甜，但缺乏果味，反而表现出霉味和泥土味。
Flavour of medium and long shelf-life Charentais cantaloupe melons was compared. Volatile and semi-volatile profiles were correlated with sensory data using multifactorial analysis. Maturity at harvest has a significant impact on the flavour of medium-shelf life fruit. Maturity at harvest had much less impact on a long shelf-life genotype. Esters and sulphur-compounds were more abundant in mature medium shelf-life fruit. The flavour profiles of two genotypes of Charentais cantaloupe melons (medium shelf-life and long shelf-life), harvested at two distinct maturities (immature and mature fruit), were investigated. Dynamic headspace extraction (DHE), solid-phase extraction (SPE), gas chromatography–mass spectrometry (GC–MS) and gas chromatography–olfactometry/mass spectrometry (GC–O/MS) were used to determine volatile and semi-volatile compounds. Qualitative descriptive analysis (QDA) was used to assess the organoleptic impact of the different melons and the sensory data were correlated with the chemical analysis. There were significant, consistent and substantial differences between the mature and immature fruit for the medium shelf-life genotype, the less mature giving a green, cucumber character and lacking the sweet, fruity character of the mature fruit. However, maturity at harvest had a much smaller impact on the long shelf-life melons and fewer differences were detected. These long shelf-life melons tasted sweet, but lacked fruity flavours, instead exhibiting a musty, earthy character.
