Analysis of Volatile Components and Characteristic Aroma Substances of Different Pomelo Peel Essential Oil Based on GC-MS Combined with ROAV Method
Gas chromatography-mass spectrometry(GC-MS)was used to analyze and identify the volatile components of the pomelo peel essential oils in 4 different cultivars,i.e.,Shatian pomelo,Sanhong pomelo,Qiangdele pomelo and Jiayuan pomelo,respectively.The key fragrance substances of the four essential oils were identified by the sensory evaluation method of relative aroma activity value(ROAV)combined with artificial sniffing.The results showed that a total of 24 volatile compounds were identified from the essential oils,and the composition and content distribution of volatiles and the sensory fragrance types of the four essential oils were different.Combined with ROAV method,the key flavor substances contained in four essential oils were mainly citral,d-limonene,β-pinene,decaldehyde and β-myrcene,respectively.The distribution differences of the above substances in different essential oils were important reasons for the formation of their respective fragrance characteristics.This study identified the key aroma components contained in different pomelo peel essential oils,which could provide a theoretical reference for the development and utilization of pomelo characteristic flavor products.
