Application:	Characterization of Flavor Profile of Sauced Pork from Different Regions of China Based on E-Nose, E-Tongue and Gas Chromatography-Ion Mobility Spectroscopy.: This study by Yuan et al. characterizes the flavor profile of sauced pork using various sensory and chromatographic techniques, including gas chromatography-ion mobility spectroscopy. It identifies key aroma compounds, including 2-ethyl-3,5(6)-dimethylpyrazine, contributing to the overall flavor profile (Yuan et al., 2024 ). The effect of thermal times of circulating non-fried roast technique on the formation of (non)volatile compounds in roasted mutton by multi-chromatography techniques and heat transfer analysis.: Liu et al. explore how different thermal processing times affect the formation of volatile and non-volatile compounds in roasted mutton, highlighting the presence of 2-ethyl-3,5(6)-dimethylpyrazine among the key aroma contributors (Liu et al., 2023 ). Investigation of the effect of over-fired drying on the taste and aroma of Lu′an Guapian tea using metabolomics and sensory histology techniques.: Zhang et al. investigate how over-fired drying affects the aroma and taste of Lu′an Guapian tea, identifying 2-ethyl-3,5(6)-dimethylpyrazine as a significant aroma compound (Zhang et al., 2024 ). Unveiling the aromatic intricacies of Wuyi Rock Tea: A comparative study on sensory attributes and odor-active compounds of Rougui and Shuixian varieties.: This comparative study by Wang et al. examines the sensory attributes and odor-active compounds of Wuyi Rock Tea, highlighting the role of 2-ethyl-3,5(6)-dimethylpyrazine in the aroma profile (Wang et al., 2024 ). Characterization of the Key Aroma Compounds in Dong Ding Oolong Tea by Application of the Sensomics Approach.: Wang et al. characterize the key aroma compounds in Dong Ding Oolong tea, identifying 2-ethyl-3,5(6)-dimethylpyrazine as one of the major contributors to its distinct aroma profile (Wang et al., 2023 ).
Biochem/physiol Actions:	Taste at 5 ppm
General description:	2-Ethyl-3(5 or 6)-dimethylpyrazine, a mixture of isomers are odor-active pyrazine compounds that are typically found in roasted foods formed due to Maillard reaction and pyrolysis of serine and threonine.
Other Notes:	Natural occurrence: Burley and Virginia tobacco, cocoa, coffee, cooked beef, peanut, Swiss cheese.
