摘要
The objective of this study was to determine the aroma and taste differences of black sesame in before and after processing from three origins via flavor and widely metabolomics. By analyzing the sensory characteristics and metabolites of raw and treated black sesame in China, Vietnam, and Myanmar, treated Chinese sesame have the most significant change in hardness after thermal processing, low viscosity and was easy to chew. The electronic nose could distinguish between raw and treated sesame due to the aroma distribution. The reason of treated sesame from China was “fragrant” is ranged from the highest content (2545.50 μg/kg) of total pyrazines including 2,5-dimethylpyrazine, 2-ethyl-5-methylpyrazine, 2,3,5-trimethylpyrazine, 3-ethyl-2,5-dimethylpyrazine. 933 metabolites were detected via a wide targeted metabolomics in the taste of raw and treated sesame. Based on the analysis of metabolites related to bitterness, 145 substances were selected. The main bitter contributors may be amino acids, dipeptides and organic acids.
