| Abstract: |
| With the recent announcement of the falsification of vanillin added in pressed fragrant sesame seed oil, whether endogenous vanillin exists in pressed fragrant sesame seed oil has become a hot spot in the industry. In order to provide theoretical reference for the daily supervision and high-quality development of pressed fragrant sesame seed oil, vanillin was briefly introduced, and from the synthesis of vanillin, combined with the domestic and international and the existing research of the author′s team, the formation mechanism of the endogenous vanillin in pressed fragrant sesame seed oil was analyzed. In addition, the direction of the research on the vanillin in pressed fragrant sesame seed oil was prospected. Sesame seeds themselves contain a small amount of vanillin, and the lignin in sesame hull is an important precursor of vanillin, which will produce a large amount of vanillin after roasting at high temperatures. These vanillin are further transferred to pressed fragrant sesame seed oil in large quantities with the oil production process, thus making the presence of endogenous vanillin in pressed fragrant sesame seed oil. Therefore, it is inaccurate to use the detection of vanillin in pressed fragrant sesame seed oil as a criterion for "fake pressed fragrant sesame seed oil". In the future, more attention should be paid to the research on the upper limit of endogenous vanillin in pressed fragrant sesame seed oil. |
