Abstract:

In order to study on volatile components under four different preprocessing models, fresh fruit samples from Gongshan, Yunnan were dried by natural drying, 55 ℃ baking, lyophilization drying and smoking drying, respectively. The dried fruit was separated into pericarp and kernel, grounded and extracted with n-hexane, and the extraction was analyzed by GC-MS. 53 components were detected at present research. Higher content and more compound types were found in the smoking drying treatment of pericarp and kernel than that of the other three treatment groups, indicating that the components of pericarp and kernel after smoking drying treatment became rich and complex. In addition, the relative content of the same compound in the kernel was significantly higher than that in the pericarp in all four treatments. Although the pericarp had more compound types, the relative content of the same compound was generally not high. The results would provide a certain technical reference for the later processing, preservation and application of grass fruit.
