桉木刨花板及其干刨花挥发性成分和气味特征分析

VOCs Analyses and Odor Characteristics of Eucalyptus Wood Particleboard and Its Dried Strands

  • 摘要: 为了解桉木刨花板及其表层、芯层干刨花挥发性有机物(VOCs)的含量和气味特征,采用顶空固相微萃取−气相色谱−质谱联用技术(HS−SPME−GC−MS)结合相对气味活性值(ROAV)对桉木刨花板和表层、芯层干刨花的VOCs组成和气味特征进行分析和评价。结果表明:在桉木刨花板和表层、芯层干刨花中分别鉴定出105、97、104种VOCs,包括芳香烃、烷烃、醛、酮、烯烃、醇及其他类化合物,烯烃类化合物含量最高。其中,相对含量较高的化合物为黄樟素、异黄樟素、(+)−香橙烯、α−姜黄烯、(+)−喇叭烯和Δ−杜松烯等。ROAV分析显示桉木刨花板和表层、芯层干刨花中气味活性成分分别有32、36、34种,其中黄樟素、芳樟醇、1,8−桉叶素、正己醛、壬醛、(+)−α−蒎烯和(E)−2−壬烯醛等8种化合物贡献较大。HS−SPME−GC−MS结合ROAV方法分析桉木刨花板VOCs的气味特征,能够直观地反映各类挥发物对板材的气味贡献情况,可为后期板材气味消除以及高品质桉木刨花板的生产提供参考。

     

    Abstract: In order to clarify the content and odor characteristics of volatile organic compounds (VOCs) from Eucalyptus wood particleboard and its surface and core layer dried strands, their VOCs components and odor characteristics were evaluate by using a headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) and relative odor activity value (ROAV). The results showed that 105, 97 and 104 VOCs including aromatic hydrocarbon, alkanes, aldehydes, ketones, alkenes, alcohols and other compounds, were identified in Eucalyptus wood particleboard and two dried strands, respectively, with the highest content of olefinic compounds. The compounds with a higher relative content were safrole, isosafrole, (+)-aromadendrene, α-curcumene, (+)-ledene and Δ-cadinene. ROAV analysis showed that there were 32, 36 and 34 kinds of odor active ingredients in Eucalyptus wood particleboard and two dried strands, respectively. Among them, eight compounds including safrole, linalool, 1.8-cineole, hexanal, nonanal, (+)-α-pinene and (E)-2-nonenal contributed significantly to the odor released from Eucalyptus wood particleboard and two dried strands. HS-SPME-GC-MS combined with ROAV method to analyze the odor characteristics of Eucalyptus particleboard VOCs, which can visually respond to the contribution of various VOCs to the odor of the boards, providing a basis and reference for the later research on the elimination of odor of the boards, and the results of the study provide a reference for the production of high-quality Eucalyptus particleboards.
