Abstract

The quality of the fruit is affected by several main ingredients and the aroma plays a fundamental role during the selection of fruit by consumers. In the case where several fruit have similar aromas and only one of them has specific health properties, it is very important to find the differences in the volatile organic compounds (VOCs) composition to distinguish these samples. Such situations are often found for hybrid fruit. Sweetie is a hybrid of grapefruit and pummelo. Sweetie fruit is characterized by high antioxidant potential and a positive effect on human health. The aim of this study was to verify the unique volatile compositional traits of three species of citrus fruit. Proton transfer reaction Time-of-Flight mass spectrometry (PTR-TOF-MS) was utilized to obtain the mass-resolved fingerprints of VOCs. The chemical formula of these VOC masses was tentatively identified. Principal component analysis was performed to evaluate the differences between the groups.

质子转移反应质谱法分析甜心(Citrus maxima × Citrus paradisi)及其亲本果实的挥发性成分。

摘要

水果的质量受多种主要成分的影响,而香气在消费者选择水果的过程中起着至关重要的作用。在几种水果具有相似的香气并且只有一种具有特定的健康特性的情况下,找出挥发性有机化合物(VOCs)成分的差异来区分这些样品非常重要。这种情况经常出现在杂交水果上。Sweetie是葡萄柚和柚子的杂交品种。甜果的特点是具有高抗氧化潜力和对人类健康的积极影响。本研究的目的是验证三种柑橘类水果独特的挥发性成分特征。质子转移反应飞行时间质谱 (PTR-TOF-MS) 用于获得 VOC 的质量分辨指纹。初步确定了这些 VOC 物质的化学式。进行主成分分析以评估组之间的差异。
