Analysis of aroma profiles in kernels of four Torreya grandis cultivars after roasting process
【Objective】 The aim of this experiment was to analyze changes in aroma profiles of kernels from different cultivars in Torreya grandis after roasting process, and provide an effective research method for finding out the best idioplasms with particular T. grandis aromas. 【Method】 In the present study, the volatiles of roasted T. grandis nuts from four cultivars (T. grandis ‘Zhuyuan’, T. grandis ‘Dingxiang’, T. grandis ‘Mufei’ and T. grandis ‘Xifei’) were analyzed using SPMS/GC-MS. 【Result】 79 aromatic components were detected using a gas chromatography-mass spectrometer (GC-MS) and were divided into nine categories, including alcohols (27), terpenes (23), aldehydes (6), benzenes (6), esters (5), alkanes (4), ketones (3), acids (2), ethers (2), pyrazine (1) and benzene derivatives (4). Terpenes were the most abundant aromatic compounds in the four T. grandis cultivars, which was expected for T. grandis ‘Zhuyan’, among which D-limonene formed the largest proportion. Results from principal component analysis (PCA) showed that the key characteristic aroma substances in T. grandis ‘Xifei’, included ketones, esters, aldehydes, benzene derivatives and terpenes. The key characteristic aroma substances in T. grandis ‘Mufei’ are terpenes and pyrazines. The key characteristic aroma substances in T. grandis ‘Zhuyan’ and ‘Dingxiang’ are ethers and acids. T. grandis ‘Xifei’ contains many specific aroma substances with characteristic aromas, including D-limonene, 2-furaldehyde, camphor, 1-nonanal and diisobutyl phthalate. T. grandis ‘Zhuyan’ contains dihydrocarvyl alcohol, T. grandis ‘Dingxiang’ contains stearic acid, and T. grandis ‘Mufei’ contains α-pinene, dipentene, muurolene, and (R)-(+)-dipentene. 【Conclusion】 T. grandis ‘Xifei’ has more specific aroma substances, and a greater number of specific aroma substances further enrich its aroma profiles.
