为了分析市售枫槭浸膏挥发性成分,建立了枫槭浸膏挥发性成分的顶空-固相微萃取-气相色谱质谱联用(HS-SPME-GC/MS)方法,分析了5种市售枫槭浸膏的挥发性成分,并采用单因素方差分析和主成分分析比较了其挥发性成分差异.结果表明:①该方法采用双保留指数对挥发性成分进行定性,提高了定性结果的准确性;②5种枫槭浸膏中共鉴定出104种挥发性成分,其中95种成分具有香气特征,但仅有11种香气成分为5种枫槭浸膏共有成分,这些成分多表现出焦香和甜香特征,是构成枫槭浸膏香气特征的重要物质基础;③5种市售枫槭浸膏挥发性成分存在显著差异,而枫槭浸膏W、XH分别与DP具有一定相似性,枫槭浸膏GZ中的柠檬烯、茴香醛、肉桂酸乙酯等香气成分使其呈现果香和辛香香韵,从而有别于其他枫槭浸膏.“,”A method coupling headspace solid-phase micro-extraction to gas chromatography/mass spectrometry was developed to analyze the constituents of commercially available maple concrete. Five commercial maple concrete products were analyzed and the differences of volatile components among them were compared by One-way AVONA and PCA. The results showed that: 1)When adopting double-retention index to qualitatively analyze the volatile components, the results were more accurate. 2) Totally 104 volatile components were identified by the developed method, in which 95 components had odor characteristics. However, only 11 aroma components were all detected in the five maple concrete products, these components offered burnt scent and sweet scent, which were important for the aroma characteristics of maple concrete. 3)The volatile components in the five maple concrete products differed significantly. Maple concrete W and Maple concrete XH had certain similarity with Maple concrete DP separately. Maple concrete GZ contained aroma components, such as cinene, p-anisaldehyde, ethyl cinnamate, etc., which offered fruit scent and spicy scent and made GZ different from the other four maple concrete products.
