Study on Aroma Components of Canarium album of Different Cultivars Based on HS-SPME-GC-MS

Headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) was used to detect and analyze the aroma of Canarium album of different cultivars to explore the characteristics of aroma components. The results showed that a total of 56 aroma compounds were detected in 9 kinds of C. album of different cultivars, all of which were mainly olefinic substances, accounting for 78.51%~89.34% of the content of the total aroma components of each variety. α-pinene, β-pinene, caryophyllene, α-caryophyllene and myrcene were the main aroma components. These aroma substances laid the foundation for the aroma of C. album. Among them, caryophyllene was a relatively high content and stable existence in various cultivars. There were also differences in odor activity value (OAV) among different varieties of C. album. Pinene was an important component of the aroma characteristics of C. album of these nine varieties, and the aroma types were pine oily and woody. There are differences in aroma substances and substance contents among different C. album varieties, and the research results can provide a basis for later C. album aroma mechanism research, breeding, promotion and quality innovation.
