Poisson, Luigi;Pittet, Jonathan;Schaerer, Anja;Mestdagh, Frederic;Davidek, Tomas research published 《 Quantitative Validation of the In-Bean Approach in Coffee Roasting》, the research content is summarized as follows. The representativeness of the so-called biomimetic “in-bean” technique was studied by following the formation of target aroma compounds during the roasting course (10 points from 0 to 400 s) in recombined coffee beans and non-treated green coffee reference beans. For this purpose, the water-soluble fraction was replaced by a biomimetic recombinate in reconstituted beans prior to roasting. The targeted anal. of key aroma compounds was performed by means of the stable isotope dilution assay and solid-phase microextraction-gas chromatog.-mass spectrometry of roasted and ground coffee samples. The results were compared to the quant. data on a green coffee reference roasted under the same conditions. The results showed similar formation kinetics for most of the evaluated volatiles, such as Strecker aldehydes, alkylpyrazines, or α-diketones. In addition, the final quantities of key odorants in both types of samples were quite comparable. Hence, the refined biomimetic approach was validated as a valuable tool in studying different aspects of flavor formation upon coffee roasting.
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., Name: Acetylpyrazine
