Soft, squashable toys known as squishies have become increasingly popular amongst children. In this study, one such toy was evaluated sensorially by a trained panel and analytically using gas chromatography-mass spectrometry/olfactometry (GC-MS/O) after thermal extraction of the sample. Sensory analysis revealed the presence of an intense and unpleasant odour exhibited by the sample. The smell was dominated by almond- and inflatable swimming aid-like, as well as malty and glue-like notes, but also pleasant odours that were described as caramel-like and coconut-like. GC-MS/O analysis identified 2-butoxyethanol, cyclohexanone, γ-nonalactone, and ethyl maltol as being the main causative substances for the overall odour of the product. The data additionally indicated that the pleasant smelling substances γ-nonalactone (coconut-like smell) and ethyl maltol (caramel-like smell) were intentionally added by the manufacturer to mask the unpleasant odour of the solvents.
柔软、可挤压的玩具俗称“慢回弹玩具”，在儿童中越来越受欢迎。在这项研究中，一个这样的玩具经过热萃取后，由经过培训的小组进行感官评估，并使用气相色谱-质谱/嗅觉测定法（GC-MS/O）进行分析。感官分析显示，样品有强烈而难闻的气味。这种气味主要由杏仁味和充气游泳辅助用品的味道、麦芽味和胶水味组成，但也有一些令人愉悦的气味，被描述为焦糖味和椰子味。GC-MS/O 分析确定 2-丁氧基乙醇、环己酮、γ-壬内脂和乙基麦芽酚是导致产品整体气味的主要物质。此外，数据还表明，制造商故意添加了具有宜人气味的γ-壬内脂（椰子味）和乙基麦芽酚（焦糖味），以掩盖溶剂的难闻气味。
