毛细管气相色谱之前的顶空进样方法已广泛用于测定不同种类样品中存在的挥发性化合物。本文描述了一种用于测定酸奶中挥发物的自动化快速系统。在用于酸奶包装的聚苯乙烯杯中发现了 35 种挥发性有机化合物 (VOC)，在酸奶样品中发现了 42 种挥发性有机化合物 (VOC)。对来自西班牙零售市场的几个样品中的苯乙烯进行了定量。
Headspace sampling methods prior to capillary gas chromatography have been widely used for the determination of volatile compounds present in very different kinds of samples. This paper describes an automated and rapid system to determine volatiles from yoghurt. Thirty-five volatile organic compounds (VOCs) were identified in polystyrene cups used for yoghurt packaging and 42 VOCs from yoghurt samples. Quantitation of styrene in several samples from the Spanish retail market was carried out.
