摘要:本研究针对成人纸尿裤在实际使用中面临的臭味物质复杂性，筛选并确定了9种具有代表性的恶臭化合物。通过综合运用检知管法、液相色谱-质谱/质谱法和热脱附-气相色谱质谱法，建立了一套科学的成人纸尿裤消臭效果检测体系。对市售不同品牌成人纸尿裤的消臭效果进行了评价，结果显示部分样品对异戊酸、2-壬烯醛和吲哚等化合物具有超过98%的消臭效果；对于氨气，添加了抑菌原材料的消臭型成人纸尿裤，其消臭效果通常超过70%，显著优于普通型纸尿裤的不足30%的消臭效果；而对甲硫醇等化合物的消臭效果则尚需改进。本研究为成人纸尿裤的消臭效果评价提供了科学依据，有助于行业质量标准的提高和产品创新。

Abstract:This study targeted the complexity of odor compounds faced by adult diapers in actual use and identified nine representative malodorous compounds. By integrating detection tube methods, liquid chromatography-tandem mass spectrometry (LC-MS/MS), and thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS), a scientific deodorization effectiveness evaluation system for adult diapers was established. The deodorizing effect of different brands of adult diapers on the market was evaluated. The results showed that some samples had a deodorizing efficiency of more than 98% for compounds such as isovaleric acid, 2-nonenal and indole; for ammonia, inhibitors were added The deodorizing effect of deodorizing adult diapers made of bacterial raw materials usually exceeds 70%, which is significantly better than the deodorizing efficiency of less than 30% of ordinary diapers; however, the deodorizing effect of compounds such as methyl mercaptan needs to be improved. This research provides a scientific basis for the deodorant property evaluation of adult diapers, contributing to the enhancement of industry quality standards and product innovation.
