摘要:采用顶空固相微萃取-气质联用色谱法（HS-SPME-GCMS）对7款无香类生活用纸（抽取卫生纸）的气味组成进行测定与分析，研究了生活用纸的气味组成，建立了一种快速测定生活用纸气味组成的方法。结果表明，诱发纸张气味组成物质主要有醛类、酸类、酯类、醇类、酮类和酚类物质。7款纸张中共检出53种挥发性成分，其中乙酸、苯酚、癸醇、异辛醇、辛酸、己醛、乙酸、丁酸、戊酸和壬醛为纸张异味的主要成分。在纸张中，少量酸类物质即可引发纸张异味；较高含量的醛类、酯类和醇类也易引发纸张气味；酮类物质不易引发纸张异味。

Abstract:The method of head-space solid phase micro-extraction/gas chromatography-mass spectrometry （HS-SPME-GCMS） was used to analyze the odor components of 7 types of tissue paper and the rapid method to determine the odor composition of tissue paper was established. The results showed that the odor components of tissue paper mainly included aldehydes， acids， esters， alcohols， ketones and phenols. A total of 53 volatile components were detected in 7 types of tissue paper， among which acetic acid， phenol， decanol， iso-octanol， octanoic acid， hexanal， acetic acid， butyric acid， pentanoic acid and nonanal were the key components of the odor. In tissue paper，minor dosage of acid substances would lead to the generation of odor， higher dosage of aldehydes， esters and alcohols would generate odor， and the ketones were not the main factors which resulted for generating odor.
