热脱附-气相色谱质谱联用法分析3种活性炭添加对燃香产品香味的缓释作用

Analysis of 3 activated carbons Sustained Release from Incense Flavors by thermal desorption-gas chromatography-mass spectrometry

以不同比表面积的椰壳活基与大麻杆基活性炭作为燃香产品Ⅰ~Ⅲ型添加剂,采用热脱附-气质联用法对燃香样品进行香气缓释实验,平行测定6次,其总峰面积及主要化合物峰面积RSD值均小于10%,重复性较好。结果表明,Ⅰ~Ⅲ型活炭对自然放置状态的燃香样品具有香味缓释功能,但缓释能力并不与其比表面积呈正比;同时,Ⅰ~Ⅲ型活性炭对点燃状态下的燃香样品香味发散有加强作用,对有毒有害物质有削弱能力,但作用能力可能与活性炭本身的纤维素含量相关。

Coconut shell activated carbon(CSAC)and hemp stem activated carbon(HSAC)with different specific surface areas were used as typeⅠ~Ⅲadditives for Burning Incense.The sustained Release experiment of Burning Incense flavors by thermal desorption-gas chromatography-mass spectrometry,and parallel measurement 6 times.The RSD values of the to⁃tal peak area and the peak area of main compounds were all less than 10%,showing good repeatability.The results showed that typeⅠ~ⅢAC had slow-release function when the Buring Icense naturally placed,but the slow-release ability was not proportional to its specific surface area.The activated carbon of typeⅠ~Ⅲenhanced the fragrance concentration of Burning Incense and weakened the noxious compound.It might be related to the cellulose content of activated carbon.
