The purpose of this study was to identify key odorants in used disposable absorbent incontinence products.
Descriptive in vitro study SUBJECTS AND SETTING:: Samples of used incontinence products were collected from 8 residents with urinary incontinence living in geriatric nursing homes in the Gothenburg area of Sweden. Products were chosen from a larger set of products that had previously been characterized by descriptive odor analysis.
Pieces of the used incontinence products were cut from the wet area, placed in glass bottles, and kept frozen until dynamic headspace sampling of volatile compounds was completed. Gas chromatography-olfactometry was used to identify which compounds contributed most to the odors in the samples. Compounds were identified by gas chromatography-mass spectrometry.
Twenty-eight volatiles were found to be key odorants in the used incontinence products. Twenty-six were successfully identified. They belonged to the following classes of chemical compounds: aldehydes (6); amines (1); aromatics (3); isothiocyanates (1); heterocyclics (2); ketones (6); sulfur compounds (6); and terpenes (1).
Nine of the 28 key odorants were considered to be of particular importance to the odor of the used incontinence products: 3-methylbutanal, trimethylamine, cresol, guaiacol, 4,5-dimethylthiazole-S-oxide, diacetyl, dimethyl trisulfide, 5-methylthio-4-penten-2-ol, and an unidentified compound.
本研究旨在确定用过的一次性吸收性失禁产品中的关键气味物质。
描述性体外研究
从瑞典哥德堡地区老年护理院中8名尿失禁居民处收集用过的失禁产品样本。产品是从先前通过描述性气味分析进行表征的一大组产品中挑选出来的。
从用过的失禁产品的潮湿区域剪下小块，放入玻璃瓶中，并冷冻保存，直至完成挥发性化合物的动态顶空采样。采用气相色谱 - 嗅觉测定法确定哪些化合物对样品中的气味贡献最大。通过气相色谱 - 质谱法鉴定化合物。
发现28种挥发性物质是用过的失禁产品中的关键气味物质。成功鉴定出26种。它们属于以下几类化合物：醛类（6种）；胺类（1种）；芳烃类（3种）；异硫氰酸酯类（1种）；杂环类（2种）；酮类（6种）；硫化合物类（6种）；以及萜类（1种）。
28种关键气味物质中有9种被认为对用过的失禁产品的气味尤为重要：3 - 甲基丁醛、三甲胺、甲酚、愈创木酚、4,5 - 二甲基噻唑 - S - 氧化物、二乙酰、二甲基三硫、5 - 甲硫基 - 4 - 戊烯 - 2 - 醇以及一种未鉴定的化合物。
