Dou, Xinjing;Zhang, Liangxiao;Yang, Ruinan;Wang, Xiao;Yu, Li;Yue, Xiaofeng;Ma, Fei;Mao, Jin;Wang, Xiupin;Li, Peiwu research published 《 Adulteration detection of essence in sesame oil based on headspace gas chromatography-ion mobility spectrometry》, the research content is summarized as follows. Sesame oil is a traditional and delicious edible oil in China and Southeast Asia with a high price. However, sesame oil essence was often illegally added to cheaper edible oils to counterfeit sesame oil. In this study, a rapid and accurate headspace gas chromatog.-ion mobility spectrometry (HS-GC-IMS) method was proposed to detect the counterfeit sesame oil where the other cheap oils were adulterated with essence. Combined with chemometric methods including principal component anal. (PCA), orthogonal partial least squares discriminant anal. (OPLS-DA) and random forest (RF), authentic and counterfeit sesame oils adulterated with sesame essence (0.5%, weight/weight) were easily separated into two groups. More importantly, 2-methylbutanoic acid, 2-furfurylthiol, methylpyrazine, methional, and 2,5-dimethylpyrazine were found to be markers of sesame essence, which were used to directly identify the sesame essence. The determination of volatile compounds based on HS-GC-IMS was proven to be an effective method for adulteration detection of essence in sesame oil.
Name: Acetylpyrazine, 2-Acetylpyrazine has been identified as one of the volatile flavor constituents in popcorn, wheat and rye bread crust.
2-Acetylpyrazine, also known as 1-pyrazinylethanone or fema 3126, belongs to the class of organic compounds known as aryl alkyl ketones. These are ketones have the generic structure RC(=O)R’, where R = aryl group and R’=alkyl group. 2-Acetylpyrazine exists as a solid, soluble (in water), and a very weakly acidic compound (based on its pKa). Within the cell, 2-acetylpyrazine is primarily located in the cytoplasm. 2-Acetylpyrazine has a bitter, bread crust, and chip taste.
2-acetylpyrazine is a pyrazine that is substituted by an acetyl group at position 2. It has been identified as one of the volatile flavor constituents in popcorn, bread crust, vinegar, and potato snacks. It has a role as a flavouring agent. It is an aromatic ketone and a member of pyrazines.
2-Acetylpyrazine is a nitrogen containing compound that has been used in biological studies. 2-Acetylpyrazine has been shown to have inhibitory properties against the growth of prostate cancer cells and other cell lines. It also inhibits the production of fatty acids and epidermal growth factor, which are important for cellular proliferation. The inhibition is due to the photochemical properties of 2-acetylpyrazine, which cause the formation of reactive species that react with biological molecules. The reactive species may be generated by either a reaction mechanism or a reaction pathway that involve coordination geometry. 2-acetylpyrazine has also been used as a fluorescence probe for fatty acid detection in lipid bilayers and liposomes., 22047-25-2.
