Yang, Yanqin;Xie, Jialing;Chen, Jiayu;Deng, Yuliang;Shen, Shuai;Hua, Jinjie;Wang, Jinjin;Zhu, Jiayi;Yuan, Haibo;Jiang, Yongwen research published 《 Characterization of N,O-heterocycles in green tea during the drying process and unraveling the formation mechanism》, the research content is summarized as follows. N,O-Heterocycles play an important role in the characteristic flavor of green tea owing to their strong odors and low odor thresholds. In this study, a rapid and sensitive method was developed to determine seven N,O-heterocycles in green tea by using headspace solid-phase microextraction Arrow (HS-SPME-Arrow) coupled with gas chromatog.-triple quadrupole-tandem mass spectrometry. The HS-SPME-Arrow extraction was performed using a Carbon WR SPME Arrow fiber. Good linear ranges (5-1000 ng/mL) were obtained, with correlation coefficients (R2) higher than 0.99 for all target compounds LODs and LOQs were in the range of 0.44-5.12 and 1.48-17.04μg/kg, resp. The recoveries of seven N,O-heterocycles were found to vary from 83.1% to 117.3%, with RSDs being lower than 10%. The dynamic changes of N,O-heterocycles during the drying process revealed that 25- and 40-min-long drying processes were key transition points. Furfural could be used as a key indicator compound for evaluating the extent of the drying. Moreover, furfural and 2-methylfuran revealed a significant pos. correlation with proline (p < 0.05). The possible formation mechanisms of N,O-heterocycles were further elaborated by simulated Maillard reactions. Our results provide a theor. foundation for the improvement and directional regulation of aroma quality of green tea during manufacturing
22047-25-2, 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., Related Products of 22047-25-2
