| Sesamin and other lignans are very important natural antioxidants in sesame seeds, which have many physiological functions. Clarification of the distribution of sesamin in the subcellular structure of sesame seeds is of great importance for the deep processing of sesame, especially for the extraction and utilization of sesamin. As sesamin is a fat soluble component, the oil body, the main existing state of sesame lipid, was taken as the main research object. The results showed that approximately 95% of sesamin and 95% of lipid were distributed in the oil body, while the rest were distributed in the endoplasmic reticulum and other membrane structures, which showed a very regular quantitative relationship between sesamin and lipid. Alkali washing had little effect on sesamin content in oil body, whereas urea could dissolve sesamin to some extent. High speed shear could destroy the microstructure of oil body, resulting in the release of sesamin. However, stone mill could protect the microstructure of oil body. |
