| Abstract: |
| In order to better control the quality of ground fragrant sesame seed oil, the color, acid value, peroxide value, fatty acid composition and flavor of sesame seed oil in different process stages were measured by sampling at the end of three main processes: sesame seed roasting, millstone grinding and oil separation by oscillation (including water adding and mixing). The results showed that the process of oil separation by oscillation made sesame seed oil have the largest a value and b value, which were 12.84 and 89.36, respectively. The acid value of sesame seed oil decreased continuously during roasting and millstone grinding, but increased after oil separation by oscillation. Compared with sesame seed oil obtained with unroasted sesame seed, roasting increased the polyunsaturated fatty acids content slightly. The results of electronic nose detection were consistent with those of GC-MS. The flavor of sesame seed oil obtained by roasting and millstone grinding was similar, while the variety of flavor substances in sesame seed oil increased and the flavor was stronger after oil separation by oscillation. In conclusion, besides the roasting process, oil separation by oscillation is also a key link that affects the quality of ground fragrant sesame seed oil, especially the color and flavor. It is necessary to strengthen the research on the change and formation of flavor substances in ground fragrant sesame seed oil at this stage. |
