Firstly, headspace solid-phase microextraction was established to determine AITC by orthogonal design. Extraction temperature, stir speed, extraction time, and desorption time were set at 40℃, 900r/min, 30min, and 5min, respectively. Under these optimal conditions, volatile flavor compounds in mustard oil, wasabi, and 'Chongcai'leaf mustard product were identified by SPME/GC/MS. In these three samples, 6,12,17 constituents were identified respectively; Allyl isothiocyanate was the main flavor compound, which accounted for 73.45%, 64.25%, 32.74% of total volatile compounds, respectively. Carbon disulfide, a hydrolysis product of AITC, accounted for 14.37% 25.40%, 51.67% of total volatile compounds respectively. There were some other isothiocycannates, such as butane, 1-isothiocyanato-, isobutyl isothiocyanate, 1-benzene, 4-isothiocyanato-, benzene (2-isothiocyanatoethyl)-, etc.

首先采用正交实验设计优化固相微萃取技术的前处理条件，结果表明，以萃取温度40℃、搅拌速度900r／min、萃取时间30min、解吸时间5min为最佳条件；在此最优条件基础上，利用SPME／GC／MS联用技术分析芥末油、青芥辣、冲菜的挥发性风味成分，分别检出6、12、17种化合物，主要风味物质均为AITC，相对丰度分别为73.45％、64.25％、32.74％；AITC的水解产物二硫化碳的相对丰度分别为14.37％、25.40％、51.67％；还检测到了其它几种异硫氰酸酯，如异硫氰酸丁酯、异硫氰酸异丁酯、异硫氰酸丁烯酯、2-苯乙基异硫氰酸酯等。
