Despite extensive research in recent years on camel milk composition and health benefits, limited scientific data exists on the volatile organic compound profiles of camel milk and its fermented product, . This study analyzed volatile organic compounds (VOCs) in raw camel milk and from six Kazakh farms across all seasons. We found that camel milk displayed higher concentrations of aldehydes, ketones, and alcohols with the main two compounds in milk being acetone and (2-Aziridinylethyl) amine. Conversely, the majority of volatile organic compounds in samples belonged to esters, but the predominant compounds by concentration were ethanol, dimethylamine, propanoic acid, and octanoic acid. Seasonality emerged as the primary driver of variation in milk, with heptanal being the most discriminative compound. Fermented milk showcased regional diversity likely driven by distinct microbial communities. Findings demonstrate the dynamic nature of camel milk's aromatic properties, which are influenced by multiple factors that contribute to its distinctive sensory characteristics.
尽管近年来对骆驼奶的成分和健康益处进行了广泛研究,但关于骆驼奶及其发酵产品的挥发性有机化合物谱的科学数据有限。本研究分析了来自六个哈萨克农场的生骆驼奶及其发酵产品在四季中的挥发性有机化合物(VOCs)。我们发现骆驼奶中醛、酮和醇的浓度较高,奶中的主要两种化合物是丙酮和(2-氮丙啶基乙基)胺。相反,发酵产品样品中的大多数挥发性有机化合物属于酯类,但按浓度计主要化合物是乙醇、二甲胺、丙酸和辛酸。季节性是牛奶中变化的主要驱动因素,庚醛是最具区分性的化合物。发酵奶表现出可能由不同微生物群落驱动的区域多样性。研究结果表明骆驼奶香气特性的动态性质,这受到多种因素的影响,这些因素促成了其独特的感官特征。
