A novel, simple and automatic method based on static headspace-gas chromatography-mass spectrometry has been developed to determine 10 low-molecular mass aldehydes that can be found in beverages, coming from the treated water used in their production. These aldehydes are the most frequently found in treated water as water disinfection by-products, so they can be used as indicators of the addition of treated water to beverages. The study covered a large number of fruit juices and soft drinks. The presence of the whole array of analytes is related to the contact with treated water during beverage production, mainly by the addition of treated water as ingredient. In particular, propionaldehyde, valeraldehyde and benzaldehyde can be used as indicators of the addition of treated water in these kinds of beverages. Among the ten aldehydes, only formaldehyde and acetaldehyde are naturally present in all kinds of fruit, and their concentrations are related to stage of the ripening of the fruit.
一种基于静态顶空-气相色谱-质谱联用的新型、简单且自动的方法已被开发出来，用于测定饮料中可能存在的10种低分子量醛类物质，这些醛类物质来自饮料生产过程中使用的处理水。这些醛类物质作为水消毒副产物在处理水中最为常见，因此可作为饮料中添加处理水的指标。该研究涵盖了大量果汁和软饮料。所有分析物的存在与饮料生产过程中与处理水的接触有关，主要是通过添加处理水作为配料。特别是，丙醛、戊醛和苯甲醛可作为此类饮料中添加处理水的指标。在这十种醛类物质中，只有甲醛和乙醛天然存在于各种水果中，其浓度与水果的成熟阶段有关。
